      <content:encoded><![CDATA[Background
Integrative Neuromuscular Training (INT) is a multi-component training approach aimed at optimizing neuromuscular function, improving athletic performance, and reducing injury-related risks. While existing studies suggest that INT can improve injury risk factors and enhance performance, its effectiveness and underlying mechanisms remain contentious, with many existing studies lacking comprehensive quantitative synthesis and subgroup analyses.

Methods
A systematic search was conducted across nine databases from their inception to August 31, 2025, for randomized controlled trials (RCTs) on the application of INT in athletes. The Cochrane Risk of Bias Assessment Tool (ROB2) was used for quality assessment. Meta-analysis was performed using Stata/MP 17.0, with risk ratios (RR) for dichotomous outcomes and standardized mean differences (SMD) for continuous outcomes. Hedges` g and 95% confidence intervals (CI) were calculated for effect sizes, and publication bias was assessed using funnel plots and Begg`s and Egger`s tests. The GRADE method was employed to assess the quality of evidence.

Results
A total of 25 RCTs (10,124 participants) were included. The meta-analysis revealed that INT is associated with a reduced injury risk in athletes (RR = 0.73, 95% CI: 0.58-0.91, p = 0.004), as well as improvements in jump performance (SMD = 0.88, 95% CI: 0.58-1.17, p < 0.001), sprinting ability (SMD = 0.75, 95% CI: 0.44-1.06, p < 0.001), change-of-direction ability (SMD = 0.97, 95% CI: 0.38-1.57, p = 0.001), and dynamic balance (SMD = 0.91, 95% CI: 0.31-1.51, p = 0.003), However, significant heterogeneity was found in most studies, and according to ROB2, the majority of studies were categorized as "having some concerns". Therefore, the certainty of the evidence should be interpreted in the context of the GRADE framework. Subgroup analysis suggests that INT may be particularly effective in adult athletes (= 18 years), female athletes, football players, and those undergoing high-frequency (= 3 sessions/week) and longer-duration (single session > 30 min) interventions.

Conclusion
Current evidence suggests that INT is associated with reduced injury risk and improvements in jump performance, sprinting, change-of-direction, and dynamic balance in athletes. Adult athletes, female athletes, and football players may benefit more significantly from INT, especially when the intervention frequency is = 3 sessions per week and the duration exceeds 30 min per session.

This study has been prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO) (registration number: CRD420251131811) and was reported in strict adherence to the PRISMA 2020 guidelines. The complete PRISMA flowchart and relevant details can be found in the supplementary materials.]]></content:encoded>

      <content:encoded><![CDATA[Abstract
Objective: This study aimed to (a) assess how female athletes from various sports perceive the impact of their menstrual cycle on training and competition performance and (b) examine whether the sport type is associated with the use of hormonal contraceptives.
Methods: An online survey consisting of 37 questions was conducted among female athletes from different sports. In total, 257 athletes (mean age: 21.1 ± 6.0 years) completed the questionnaire.
Results: Overall, 40% of participants reported health complaints during their menstrual cycle, with a higher prevalence among athletes under 18 years of age (54%) compared to those over 18 (27%). A total of 53% (n = 135) perceived a performance impact related to their menstrual cycle. Of these, 49% (n = 66) reported performance decreases, particularly during menstruation, while 9% (n = 12) reported increases, and 57% (n = 77) noted fluctuations across different phases. Regarding contraceptive use, 49% (n = 126) of all athletes reported using contraceptives; 6% used non-hormonal methods. Contraceptive use varied by sport type (e.g., 73% in aesthetic sports vs. 35% in team sports) but not by age group. Interestingly, 38.5% had not received medical information about associated risks or side effects.
Conclusion: The findings indicate that perceived performance decreases are most commonly reported during the menstruation phase. Contraceptive use patterns vary across sport disciplines, highlighting the potential role of sport-specific demands in reproductive health management. These insights underline the importance of individualized education and training adaptation strategies, particularly in youth and high-demand sports settings.]]></content:encoded>

      <content:encoded><![CDATA[Abstract

This study examined the sex-related variation in the developmental changes of maximal short-term power outputs in young Brazilian volleyball athletes while considering the potential influence of body size. The study included 75 participants, comprising 35 females and 40 males aged between 10.5 and 17.8 years. Performance assessment included the countermovement jump, 10 m sprint, 2 kg medicine ball throw and volleyball-specific agility. Athletes were measured 3-4 times over 12 months. Bayesian hierarchical models were used to model developmental trends across adolescence. The results revealed substantial developmental improvements in maximal short-term power outputs during adolescence, with particularly noteworthy advancements observed among male athletes. Our model predictions revealed a pronounced non-linear increase in jumping and sprint performance at around ages 14 and 16 years for females and males, respectively; however, further improvements plateaued once these peak levels were attained, resulting in negligible gains. Female athletes displayed a markedly lower rate of development in the 2 kg medicine ball throw compared to male athletes. Conversely, there were no sex-based differences in the rate of linear performance improvement in the volleyball-specific agility test. These findings offer valuable insights to coaches, helping them better comprehend the asynchrony in the progression of volleyball-specific maximal short-term power outputs during adolescence.


Zusammenfassung

Diese Studie untersuchte geschlechtsspezifische Unterschiede in den Entwicklungsveränderungen der maximalen kurzzeitigen Leistungsfähigkeit bei jungen brasilianischen Volleyballspielern unter Berücksichtigung des möglichen Einflusses der Körpergröße. An der Studie nahmen 75 Personen teil, darunter 35 weibliche und 40 männliche Athleten im Alter von 10,5 bis 17,8 Jahren. Die Leistungsbewertung umfasste den Countermovement Jump, einen 10-Meter-Sprint, den Wurf eines 2-kg-Medizinballs sowie einen volleyballspezifischen Agilitätstest. Die Athleten wurden 3 bis 4 Mal über einen Zeitraum von 12 Monaten gemessen. Bayesianische hierarchische Modelle wurden verwendet, um Entwicklungstrends während der Adoleszenz zu modellieren. Die Ergebnisse zeigten signifikante Entwicklungsverbesserungen in der maximalen kurzzeitigen Leistungsfähigkeit während der Adoleszenz, wobei insbesondere bei männlichen Athleten bemerkenswerte Fortschritte festgestellt wurden. Unsere Modellvorhersagen ergaben einen ausgeprägten nichtlinearen Anstieg der Sprung- und Sprintleistung bei etwa 14 Jahren für weibliche und 16 Jahren für männliche Athleten. Nach Erreichen dieser Spitzenwerte stagnierten jedoch weitere Verbesserungen, was zu minimalen Zuwächsen führte. Weibliche Athleten zeigten eine deutlich geringere Entwicklungsrate beim Wurf des 2-kg-Medizinballs im Vergleich zu männlichen Athleten. Umgekehrt gab es keine geschlechtsspezifischen Unterschiede in der linearen Leistungsverbesserung beim volleyballspezifischen Agilitätstest. Diese Ergebnisse liefern wertvolle Erkenntnisse für Trainer, um die Asynchronität in der Entwicklung der volleyballspezifischen maximalen kurzzeitigen Leistungsfähigkeit während der Adoleszenz besser zu verstehen.]]></content:encoded>

      <content:encoded><![CDATA[Abstract
Objective: The purpose of this study was to explore the effects of core combined lower limb strength training on medley turning technique of adolescent swimmers.
Methods: Ten female adolescent swimmers were selected for 8-week core combined lower limb strength training. The swimmers completed the core endurance, squat jump test, and 200 m individual medley race before and after training. Core endurance test included trunk extensor and flexor endurance tests; the Kistler MARS (5695BQ2, Kistler Instrument, Winterthur, Switzerland) system was used to perform squat jump test to evaluate the lower limb power. Underwater and digital video cameras and one TritonWear sensor (Triton 2, LUCID Vision Labs, Richmond, BC, Canada) were used to collect the turning parameters.
Results: Compared with pretraining, the time of extensor and flexor endurance increased by 49.5 s (p = 0.005) and 47.5 s (p = 0.005) respectively. Squat jump height, relative peak force and relative peak power increased by 0.02 m (p = 0.042), 0.26 N/kg (p = 0.003), and 3.74 W/kg (p = 0.003) respectively. The -5 m to 5 m times in all swimming turns had significantly decreased by 0.70 s (p = 0.004), 0.53 s (p = 0.018), and 0.53 s (p = 0.002), respectively. The tuck times in backstroke to breaststroke and breaststroke to freestyle turns significantly decreased by 0.26 s (p = 0.028) and 0.24 s (p = 0.034), respectively. The hip joint angle in butterfly to backstroke turn decreased by 8.50° (p = 0.005), and the knee joint angle decreased by 4.87° (p = 0.009). The hip joint angle in breaststroke to freestyle turn decreased by 7.83° (p = 0.016). The maximal acceleration in all swimming turns had significantly increased by 2.73 m/s2 (p = 0.031), 3.47 m/s2 (p < 0.001), and 2.12 m/s2 (p = 0.040), respectively.
Conclusion: An 8-week core combined lower limb strength training can improve the core strength and lower limb power in adolescent swimmers, optimize the tuck technique, reduce the -5m to 5m time, and increase the maximum acceleration during the swimming turns in 200 m individual medley.]]></content:encoded>

      <content:encoded><![CDATA[Bilateral strength differences are frequently discussed as a risk factor for noncontact injuries. Research on this topic, however, is inconclusive. Therefore, the purpose of this study was to investigate the concordance of isokinetic bilateral strength differences in single-joint and multi-joint movements of the lower limb. Forty-nine track and field athletes performed multi-joint leg extensions and single-joint knee and hip extensions at two different velocities. Directed bilateral differences were calculated for all measurements. Concordance correlations were calculated to investigate magnitude and direction of the differences. Additionally, multiple linear regressions for the multi-joint movements as well as an explorative factor analysis were performed. A neuronal net was constructed to investigate whether the bilateral difference in the fast multi-joint leg extension could be predicted from the single-joint measurements. The results indicate poor to fair concordance and the factor analysis identified two independent factors: factor 1 represents bilateral differences in multi-joint and knee extensions, while factor 2 represents differences in hip extensions. The neuronal net was not able to predict the bilateral differences in multi-joint leg extensions with sufficient accuracy. Neither magnitude nor orientation of the observed strength disparities exhibit a discernible pattern across the evaluated parameters. The interchangeable utilization of bilateral strength differences from different testing conditions must be precluded. Consequently, when evaluating interlimb symmetry, it is imperative to conduct a diverse array of tests.]]></content:encoded>

      <content:encoded><![CDATA[Mental health is becoming increasing focus in sport, especially after sport injuries or career termination. This review highlights the accessibility and effects of psychological interventions and extends existing evidence by including both injury- and career termination-related interventions across diverse study designs. We conducted a systematic search in June 2025 across four databases (PubMed, SPORTDiscus, CINAHL, PsycInfo) to identify peer-reviewed clinical studies involving injured elite athletes or those at the end of their careers (aged 16+), who received psychological interventions such as psychotherapy, Acceptance and Commitment Therapy (ACT) or mindfulness-based approaches. In all, 13 studies were included with a total of 298 participants. The studies employed various psychological approaches, e.g., ACT, mindfulness training, Eye Movement Desensitization and Reprocessing (EMDR), goal-setting or behavioral activation (BA). The quality of the studies was assessed by using the Joanna Briggs Institute (JBI) checklist for observational studies, JBI checklist for quasi-experimental studies and the PEDro scale for randomized controlled trials (RCTs). Findings indicate that psychological interventions enhance mental health and support rehabilitation. Two included studies focused on athletes` post-sport careers. Due to the variety of investigated sports and methodological approaches, it remains unclear whether individual or team athletes benefit more. The studies offered a broad overview but limiting detailed insights into specific interventions. This study underscores the need for standardized and easily accessible psychological support for injured athletes.]]></content:encoded>

      <content:encoded><![CDATA[Background
The rise in youth karate competition participation correlates with elevated injury risk. This study investigated injury incidence and patterns among Iranian junior athletes at the 2023 National Karate Championships (Tehran, April-May 2023), the official selection event for the national team, considering differences by age, sex, weight, and bout characteristics.

Methods
A prospective cohort design was employed, analyzing data from 1391 athletes across 1544 bouts. Injury data were systematically collected by qualified medical personnel using standardized forms. Injury incidence rates (IIRs) were rigorously calculated per 1000 athlete-exposures (AEs) and per 1000 min of exposure (MEs) to account for varying exposure durations.

Results
A total of 527 injuries were recorded during the competition. The overall IIR was determined to be 18.94 per 1000 AEs and 9.02 per 1000 MEs. The face was identified as the most commonly injured anatomical site, accounting for 46% of all injuries, while contusions were the most frequent injury type, comprising 48%. Athletes in the Under-21 (U21) male category exhibited the highest injury rates. Furthermore, more than half (52%) of all recorded injuries occurred within the first minute of a bout, and losing athletes sustained a disproportionately high 59% of the total injuries.

Conclusion
In conclusion, this study identified a high injury incidence among Iranian junior karate athletes, with the face being the most commonly affected region and contusions the predominant injury type. Male and U21 athletes showed notably higher injury rates, particularly early in bouts and among those who lost. These findings highlight the need for targeted preventive strategies and serve as a national benchmark for future injury surveillance in youth karate.]]></content:encoded>

      <content:encoded><![CDATA[This study examines how coaches, athletes and managers influence and reproduce cultural expectations of performance within their teams, and how athletes respond to these expectations. Methodologically, the study is based on qualitative interviews with athletes, coaches and managers within two Scandinavian elite football clubs. Using a Foucauldian perspective on power, the analysis shows how coaches and managers normalise athlete sacrifice, discomfort and conformity within team culture, setting high performance standards that athletes internalise and help to sustain. Importantly, athletes are monitored and disciplined into particular behaviours, though paradoxically, these disciplinary practices often inhibit their ability to meet performance standards fully. Additionally, results highlight how recruitment practices pre-screen for cultural compatibility, laying a foundation for maintaining discipline and cohesion. The findings provide insights into how disciplinary power operates within elite sports environments, shaping behaviours, attitudes and beliefs that may prove detrimental to athlete health.]]></content:encoded>

      <content:encoded><![CDATA[The primary aim of this study was to assess the objective and the perceived priming effect of resisted sled sprints (RSS) on 30 m skating sprint performance in under-20 elite male ice hockey players. Further aims were to determine the impact of pre-priming exercise neuromuscular status on the priming effect of RSS, and whether RSS affects initial acceleration (0-10 m) and high-speed skating (20-30 m) differently in skating sprints. Twenty-one national-level ice hockey players (17.8 ± 0.9 yr) performed 4x15 m RSS with a resistance equating to 50% velocity decrement (Vdec), 1 h (1h-PRE) and 24 h (24h-PRE) before performing a 30 m skating sprint. Neuromuscular status was determined with the mean reactive strength index modified (RSImod) of three countermovement jumps. A repeated measures analysis of variance (ANOVA) yielded no differences in skating sprint times in either timing condition for 0-30, 0-10, and 20-30 m. RSImod was significantly lower (p = 0.01) in the 1h-PRE intervention group (1h-INT) compared to baseline, showing a large effect size of neuromuscular fatigue in 1h-INT (g = 0.89). There was no difference in readiness to perform and ratings of perceived performance in either timing condition. These results suggest that 4x15 m RSS at 50% Vdec provides no priming effect in non-fatigued junior ice hockey players following 1 and 24 h. A possible priming effect exists after 1 h in fatigued athletes. Skating sprint performance was not affected in any condition. ]]></content:encoded>

      <content:encoded><![CDATA[Background: Shoulder injuries are highly prevalent among handball players due to the sport`s high-intensity and repetitive overhead movements, which place substantial mechanical demands on the shoulder joint. These injuries not only compromise performance but may also increase the risk of long-term musculoskeletal complications. Evaluating the isokinetic properties of the shoulder`s internal and external rotator muscles provides critical insights into muscle imbalances and can guide targeted preventive strategies.

Objective: This study aimed to analyze and compare the isokinetic characteristics of shoulder internal and external rotator muscles during concentric contractions at ten angular velocities between amateur and professional handball players. Methods: Twenty-four handball players (12 amateurs and 12 professionals) participated in this cross-sectional comparative study. The mean age of the amateur group was 21.16 ± 1.11 years, and 21.66 ± 1.66 years for the professional group. Mean height was 1.82 ± 0.50 m for amateurs and 1.86 ± 0.58 m for professionals, while mean weight was 74.66 ± 5.86 kg and 82.83 ± 15.44 kg, respectively. Isokinetic data were collected at ten angular velocities using the Biodex System 3 Pro device. Key outcome measures included peak torque, time to peak torque, and muscle strength ratios.

Results: Professional players demonstrated significantly higher peak torque at higher angular velocities (270°/s and 300°/s) compared to amateurs (p < 0.05). External rotator muscles exhibited significant differences across all velocities (p < 0.05), suggesting enhanced shoulder stabilization in professionals. Professionals reached peak torque faster, which may confer performance advantages but could marginally increase the risk of shoulder impingement. At higher velocities, internal rotators in professionals showed greater angles at peak torque (p < 0.05). Additionally, muscle strength ratios were more favorable in professional players at higher velocities (p < 0.05).

Conclusions: High-velocity training is crucial for optimizing shoulder internal and external rotator muscle performance in handball players. Professional athletes displayed faster and stronger muscular responses, whereas amateurs exhibited delayed peak torque and weaker external rotators, with notable deviations from standard strength ratios. These findings highlight the importance of isokinetic assessment at multiple velocities to inform training interventions aimed at enhancing performance and minimizing injury risk in both amateur and professional handball players.]]></content:encoded>

      <content:encoded><![CDATA[Background
In taekwondo, sufficient kicking force is required to score valid points on electronic protectors. Impact force varies with kicking speed, and lower extremity strength is crucial for optimal scoring.

Objective
To investigate the relationship between isokinetic strength and segmental acceleration in the striking leg during roundhouse kicks (RHKs).

Methods
Seventeen female taekwondo athletes (age: 208 ± 1.81 years) participated. Lower limb isokinetic strength was assessed with a dynamometer, and segmental accelerations were measured using inertial sensors. Correlations between isokinetic moments and accelerations during mid-level and high-level RHKs were analyzed using Fisher's Z transformation.

Results
During mid-level RHKs, knee flexion moments correlated with ankle accelerations, while high-level RHKs showed additional correlations between hip flexion moments and segmental accelerations. Joint accelerations were driven by flexor moments (hip and knee flexion). No bilateral differences were found in isokinetic strength or segmental accelerations, except for ankle acceleration during high-level RHKs (p = 0.039). Significant increases in segmental accelerations (p < 0.05) strengthened by Fisher Z transformation, particularly for knee flexion and ankle acceleration (p < 0.05).

Conclusions
Mid-level RHKs are knee-dominant, while head-level kicks require greater contributions from both knee and hip flexion. Strengthening both extensor and flexor muscles is vital for optimizing kicking performance]]></content:encoded>

      <content:encoded><![CDATA[Inline speed skating is a very technical sport, and therefore behavioural patterns are a very important subject to analyse. There are several types of curves, and this study proposes to compare skaters` performance on 2 types of curves: i) banked direct curve and ii) parabolic banked curve. To register skaters' motor patterns, an observation system was used. This study focused on registered skaters (aged between 17 and 25 years) performance when skating the 2nd curve of a 200-meter flying lap. Image capture will be done with 3 cameras shooting simultaneously. Existing patterns will be detected using the Theme 5.0 software (Magnusson, 2000; Magnusson et al., 2004). We observed different alphanumeric codes and different numbers of codes in the 6 moments of observation as in Medeiros et all (2025). Behavioural patterns were not similar when compared between tracks.]]></content:encoded>

      <content:encoded><![CDATA[Objective
This study aimed to investigate the physiological, hematological, and performance adaptations resulting from sequential blocks of endurance (EnT), speed (SpT), and strength (StT) training in elite Ethiopian middle- and long-distance male runners. Using a quasi-experimental repeated-measures design with a fixed order (EnT -> StT -> SpT), twenty male athletes (23.7 ± 3.2 years; 3000-10000 m events) completed three 6-week training blocks. Physiological (estimated VO2max, resting heart rate, running economy), hematological (hemoglobin, hematocrit, Red blood cell count (RBC), White blood cell count (WBC)), and performance measures (400 m speed, 5000 m time trial, 12-minute Cooper test) were assessed pre- and post-intervention using paired T-tests and repeated-measures ANOVA.

Results
The endurance training block produced significant improvements in aerobic and hematological parameters, including estimated VO2max (+ 6.20 ml·kg-¹·min-¹), resting heart rate (- 3.80 bpm), and hematocrit (+ 4.35%) (all p < 0.001). Subsequent strength and speed training blocks were associated with gains in running economy (StT: -4.2% oxygen cost, p < 0.01; SpT: -1.8%, p < 0.05) and 400 m speed (StT: -1.21 s, SpT: -1.00 s; both p < 0.001). All training modalities contributed to improved 5000 m times (EnT: -18 s, p < 0.01; SpT: -9 s, p < 0.01; StT: -6 s; p < 0.05). The sequential training approach resulted in complementary improvements across aerobic, anaerobic, and neuromuscular domains.]]></content:encoded>

      <content:encoded><![CDATA[The challenge of athlete participation in decision-making in the context of elite sport is a trending topic in both science and society. Hence, this scoping review aims to systematise the heterogeneous international research discourse, analyse the theoretical frameworks employed, and examine the methodological approaches used to address issues of athlete involvement and power in elite sport organisations. Informed by the PRISMA guidelines for scoping reviews, a systematic literature search was conducted in Web of Science, PsychArticles, PsychInfo, and PubMed. The forty-two peer-reviewed articles included reveal, that participation in decision-making occurs with varying degrees of athlete involvement. Seven discourses were identified and categorised into individual commitment, shared decision-making, and governance in elite sport. The findings also indicate a variety of theoretical and methodological approaches being employed to address athlete participation. The findings provide an innovative foundation for further research on the conceptualisation of athlete participation in decision-making in elite sport.]]></content:encoded>

      <content:encoded><![CDATA[Purpose:
Rotation of the body about its longitudinal axis or "body roll" in front crawl swimming may reduce injury risk, enhance propulsion, and reduce drag. An upper limb amputation may hinder body roll and diminish the benefits associated with this movement. This study examined the external fluid torques (buoyant and hydrodynamic) acting on unilateral upper limb amputee swimmers and their influence on whole-body roll, shoulder roll, and hip roll during front crawl.

Methods:
Ten Para swimmers with unilateral at-elbow amputation completed front crawl trials at sprinting speed. Three-dimensional motion analysis provided shoulder roll and hip roll angle-time histories. Swimmer`s center of mass (CM), center of buoyancy (CB), and whole-body angular momentum (H) were determined relative to the body roll axis. Whole-body roll was calculated by dividing H by the moment of inertia at each time and integrating over the cycle. Buoyant torque was obtained from the cross product of the CM-CB position vector and the buoyant force vector. Net external torque was computed as the time derivative of H, and hydrodynamic torque was then found by subtracting buoyant torque from net external torque.

Results:
Shoulder roll amplitude, maximum buoyant torque, and buoyant torque-impulse were greater (P < 0.01) during recovery (over-water phase) of the nonimpaired limb than during recovery of the impaired limb. No significant bilateral differences were found for whole-body roll, hip roll, or trunk-twist amplitudes. Mean contributions of buoyant torque and hydrodynamic torque to whole-body roll over the full upper limb cycle were 48% and 52%, respectively.

Conclusions:
Swimmers with unilateral forearm amputation experience an asymmetric buoyant torque, requiring them to sacrifice propulsive force to counterbalance the torque asymmetry and maintain symmetric whole-body roll.]]></content:encoded>

      <content:encoded><![CDATA[Purpose:
To determine the energetic and hormonal predictors of advanced menstrual recovery (>=2 consecutive menstrual cycles of <36 d) in the REFUEL study, a 12-month intervention of increased energy intake in exercising women with oligo/amenorrhea.

Methods:
Participants (21.8 ± 0.7 yr; N = 25) were categorized based on whether they experienced advanced menstrual recovery (REC) or not (non-REC). Potential recovery predictors were measured at baseline (BL) and at the time point preceding advanced menstrual recovery (PRE). For the non-REC group, PRE was the measurement preceding the last two menstrual cycles/28-d amenorrheic monitoring periods recorded during the intervention. Predictors included body composition, energy intake, energy availability, urinary estrone-1-glucuronide and pregnanediol glucuronide, serum metabolic hormones, and resting metabolic rate variables. T tests and Mann-Whitney U tests assessed group differences. Logistic regressions determined recovery predictors.

Results:
The REC group had higher percent fat (25.7 ± 1.0% vs 21.8 ± 1.0%, P = 0.006) and fat mass (14.7 ± 0.7 vs 11.6 ± 0.7 kg, P = 0.003) at BL and fat mass (15.3 ± 0.6 vs 13.4 ± 0.5 kg, P = 0.019), insulin-like growth factor-1 (273.1 ± 13.5 vs 229.6 ± 19.3 ng·mL-1, P = 0.036), and leptin (7.5 ± 1.3 vs 4.6 ± 0.7 ng·mL-1, P = 0.033) at PRE than the non-REC group. Estrone-1-glucuronide and pregnanediol glucuronide increased in the REC group (from 27.6 ± 4.5 to 35.3 ± 5.0 ng·mL-1, P = 0.007; from 1.2 ± 0.2 to 1.3 ± 0.2 µg·mL-1, P < 0.001). Predictors of menstrual recovery were the number of menstrual cycles experienced in the 12 month before the intervention, BL percent fat and fat mass, and fat mass and insulin-like growth factor-1 at PRE (P < 0.05). Combining BL fat mass and previous 12-month menstrual frequency correctly classified 91.3% of women as REC or non-REC.

Conclusions:
A higher fat mass and a previous pattern (12-month) of frequency of menses may have an important role for advanced menstrual recovery to be achieved.]]></content:encoded>

      <content:encoded><![CDATA[Purpose:
To investigate performance, recovery, sleep, nocturnal physiology, ovarian hormone concentrations, and menstrual cycle symptoms within and between menstrual cycle phases and establish within-phase reliability of these measures.

Methods:
Twenty naturally cycling, trained female participants (age 27 ± 5 yr) completed a repeated measures study design. Serum estradiol and progesterone concentrations, countermovement jumps, isometric mid-thigh pulls, a repeated 5 km cycle time trial, and two nights of sleep architecture were measured in phases one, three, and four of two menstrual cycles. Sleep and wake measures from activity monitoring, nocturnal heart rate (HR) measures from the Oura Ring, and menstrual cycle symptoms were monitored daily. Statistical analyses included linear mixed models and reliability measures.

Results:
Estradiol concentrations were significantly lower in phase one versus three, one versus four, and three versus four (P < 0.001 to 0.04) in both menstrual cycles. Progesterone concentrations were significantly lower in phase one versus four, and three versus four (P < 0.001) in both menstrual cycles. Symptoms were significantly higher in phase one versus three and four (P < 0.001) in cycle one only. No significant differences between phases were found for performance, recovery, and sleep in either cycle, except for the nonrapid eye movement stage three (N3%) sleep in cycle two. Nocturnal average HR was significantly lower (P < 0.001) and HR variability higher (P < 0.001) in phase one versus four in both cycles. Ovarian hormone concentrations were highly variable within each phase (coefficients of variance 28%-95%), while performance and recovery demonstrated minimal variability in both cycles.

Conclusions:
Performance, recovery, and sleep in trained female participants remained consistent despite ovarian hormone fluctuations. Consequently, practitioners should test athletes when convenient, using accurate and reliable assessments rather than synchronizing testing with specific menstrual cycle phases.]]></content:encoded>

      <content:encoded><![CDATA[Purpose:
This study investigated the acute effects of two structured breathwork methods on autonomic recovery following maximal exertion.

Materials and Methods:
A randomized control trial was conducted with 62 cadets (44 males and 18 females) assigned to three distinct groups: box breathing (BB), cyclic sighing (CS), or spontaneous breathing control. Participants performed a graded exercise test to assess maximal oxygen consumption (VO2). High-frequency heart rate variability (HF-HRV) and heart rate recovery (HRR) were collected to evaluate autonomic recovery and parasympathetic reactivation. HF-HRV was analyzed at three time points: baseline (Pre), 1-3-min postexercise recovery (Post1), and 4-6-min postexercise (Post2). HRR was measured at 1- and 3-min intervals, analyzing reductions from peak heart rate captured at VO2max. All analyses were evaluated using a 3 (group) × 3 (time) mixed-design repeated-measures analysis of variance.

Results:
All groups were comparable in age, weight, height, and body mass index (21 ± 3 yr; 77.4 ± 15.4 kg; 173.1 ± 9.0 cm; 25.7 ± 4.0 kg·m-2, respectively). HF-HRV revealed significant main effects for time (F(2,118) = 465.01, P < 0.001, Eta2=0.89), group (F(2,59) = 8.20, P < 0.001, Eta2=0.22), and time × group interaction (F(4,118) = 3.54, P = 0.009, Eta2=0.21). Both the CS and BB groups had greater increases in HF-HRV from Post1 to Post2 when compared to spontaneous breathing (P = 0.001). HRR improved across all participants from 1- to 3-min postexercise with n group level differences (F(1,59) = 33.51, P < 0.001, Eta2=0.36).

Conclusions:
Structured breathwork following maximal exertion significantly accelerated parasympathetic reactivation as reflected by HF-HRV. Both BB and CS offer a simple field-ready intervention aimed to enhance operational readiness for tactical populations through enhancing acute physiological recovery.]]></content:encoded>

      <content:encoded><![CDATA[Introduction:
Anterior cruciate ligament injuries are debilitating, often requiring surgical reconstruction and prolonged recovery. Female adolescent athletes are at particularly high risk for anterior cruciate ligament injury and display distinct neuromuscular control patterns during jump landing that further increase injury risk. Neuromuscular training (NMT) designed to reduce injury risk can be enhanced with automated movement corrective biofeedback to improve neuromuscular control and landing biomechanics; however, the central nervous system responses to targeted NMT that underlie adaptive biomechanical responses are not well-understood.

Purpose:
This study aimed to identify the effects of NMT on landing biomechanics and task-related brain activity, examine the relationship of changes in these variables, and determine if additive visual biofeedback (augmented versus sham) provides a meaningful impact on injury-related outcomes.

Methods:
This study included 55 female middle- and high-school athletes (agemean = 15.73 ± 1.40 yr) who participated in ~6 wk of NMT (3×/wk; 18 sessions), which included up to 12 sessions of additive biofeedback (augmented: n = 28; sham: n = 27). Testing at pre- and post-NMT included a drop vertical jump task to assess landing biomechanics (sagittal and frontal plane hip and knee kinematics and kinetics) and a supine bilateral leg press task during functional magnetic resonance imaging to assess brain activity during a complex sensorimotor movement task.

Results:
NMT improved landing biomechanics (Eta2 range = 0.04-0.41, Ps < 0.049) and reduced task-related brain activity in sensorimotor regions (Prange = 0.015-0.032). Pre-post increases in postcentral gyrus brain activity predicted a reduction in left knee peak abduction moment (odds ratio = 22.61, 95% confidence interval [2.41, 212.21], P = 0.048). Additive biofeedback did not appear to influence outcomes of interest.

Conclusions:
NMT improved sensorimotor efficiency and landing biomechanics. However, increased somatosensory activity emerged as a critical predictor of improved landing patterns, highlighting the role of enhanced sensory processing in biomechanical risk-reduction.]]></content:encoded>

      <content:encoded><![CDATA[Background:
Brain lateralization, the hemispheric specialization of functional networks, is essential for motor and cognitive functions. However, how intensive athletic training shapes hemispheric organization remains poorly understood. This study investigated the formation of functional lateralization in elite athletes through long-term intensive training and its potential alteration by external factors, specifically sport-related concussions.

Methods:
Resting-state functional magnetic resonance imaging data were collected from 13 world class gymnasts (WCGs) and 14 nonathletic controls. Longitudinal data were collected from 18 soccer players and eight golfers before and after one season, with concussions monitored in the soccer players. Laterality indices of hemispheric integration and segregation (LIint and LIseg) were calculated to quantify hemispheric differences in information processing for each brain region, and the standard laterality index (LI) was employed to measure hemispheric asymmetry. Associations between laterality indices and neurotransmitter receptor/transporter densities were examined. Postseason changes in these indices were assessed to evaluate the effects of concussion on brain lateralization.

Results:
The WCGs showed significantly increased LIint in several left-hemispheric regions, including the precentral gyrus, cingulate gyrus, thalamus, superior parietal lobule, and lateral occipital cortex compared with the healthy controls, although no significant differences were found in LIseg. Furthermore, the LI analysis revealed that the WCGs showed higher hemispheric asymmetry in the left precentral gyrus, cingulate gyrus, and thalamus. These laterality indices also were positively correlated with certain neurotransmitters. Similar patterns of enhanced lateralization and neurotransmitter associations were observed in soccer players and golfers. However, no significant changes in laterality indices were observed as a result of concussions sustained during the season.

Conclusions:
Long-term intensive training enhances functional integration in the left hemisphere, leading to stable brain lateralization patterns resilient to sport-related concussions.]]></content:encoded>

      <content:encoded><![CDATA[Background
Triathlon combines swimming, cycling, and running over varying distances and has grown in popularity in recent years. Despite this, few studies investigate the prevalence and risk factors of injuries. This study aimed to analyze injury prevalence and distribution across body regions in Brazilian triathletes, and to identify predictive factors associated with injury development.

Methodology
A cross-sectional study was conducted with 758 Brazilian triathletes through an online form. Data collected included sociodemographic and anthropometric information, sports participation duration, injuries in the past 12 months, and number of competitions. Descriptive statistics were applied, with group comparisons using t-test, Mann-Whitney, or Chi-square tests. Binary logistic regression identified injury predictors, with variables (p < 0.20) entered into multiple regression via forward selection. Model fit was assessed using R² Cox & Snell, R² Nagelkerke, and ROC curve analysis.

Results
Of the 758 triathletes, 614 (81%) were male. More than half (n = 425) reported an injury in the past 12 months, most frequently in the lower limbs, particularly the knee (16.88%). Logistic regression revealed associations between injury occurrence and receiving prevention guidance from a physician (OR = 0.512; 95% CI: 0.320-0.818; p = 0.005), physiotherapist (OR = 0.249; 95% CI: 0.178-0.348; p < 0.001), and physical education professional (OR = 0.338; 95% CI: 0.244-0.467; p < 0.001). Participation in Ironman 70.3 distance in the last year increased injury likelihood (OR = 1.018; 95% CI: 1.216-2.339; p = 0.002). The ROC curve demonstrated good discriminative capacity (AUC = 0.759; 95% CI: 0.724-0.793; p = 0.001).

Conclusion
Lower limb injuries were the most prevalent among Brazilian triathletes. Injury prevention guidance from physicians, physiotherapists, and physical education professionals was associated with reduced risk, whereas competing in Ironman 70.3 distance increased injury likelihood. The predictive model showed good accuracy.]]></content:encoded>

      <content:encoded><![CDATA[Background
The ITN (International Tennis Number) test is frequently applied to determine the general game success of tennis players. Mental training is widely used to improve the athletic performance. In this context, this study aimed to investigate the effect of an 8-week mental training program applied to male tennis players on ITN test performances.

Method
Twenty amateur male tennis players voluntarily participated in this study. This study was conducted with a quasi-experimental design and the participants were randomly divided into Tennis and Tennis + Mental training groups. The Tennis group performed only tennis-specific training for 45 minutes, 2 days a week for 8 weeks. The Tennis + Mental training group performed 45 minutes of mental training (imagery, focus, self-talk, and breath control) before each tennis training session, followed by similar training with the tennis group, and the tennis players` ITN test performances were measured as pre- and post-tests. IBM SPSS package program was used to analyze the obtained data. Two-way repeated measures ANOVA was used to determine the difference between the ITN test and its components of the Tennis and Tennis + Mental training groups. In addition, the percentage differences of time points according to the groups were calculated with the formula "% Delta = (Pre-test - Post-test) / Pre-test *100".

Results
There was no statistically significant difference between the ITN test performance of the Tennis and Tennis + Mental training groups. When the measurement times of the groups were compared, it was found that there was a statistically significant difference between the ITN test performances. When group and time interactions in ITN test performances were analyzed between groups, a statistically significant difference was found. According to these results, while the ITN test performance of the Tennis group increased by 6.35%, the ITN test performance of the Tennis + Mental training group increased by 16.51%.

Conclusion
It was determined that the ITN test scores of tennis players increased through both Tennis and Tennis + Mental training, applied for eight weeks. However, it was determined that mental training in addition to tennis training provided a higher level of improvement in ITN test performances.]]></content:encoded>

      <content:encoded><![CDATA[Objective
The purpose of this study is to systematically review and meta-analyze the effects of in-season flywheel resistance training (FRT) compared to traditional resistance training (TRT) on vertical jump and linear sprint performance in team-sport athletes. Additionally, this study aims to explore the moderating effects of training parameters (such as frequency, intensity, and duration) on training outcomes.

Methods
This systematic review and meta-analysis followed PRISMA guidelines and was registered in PROSPERO. Five databases were searched for randomized controlled trials comparing in-season flywheel resistance training (FRT) with traditional resistance training (TRT) on vertical jump and sprint performance in team-sport athletes. Risk of bias was assessed using the Cochrane RoB 2 tool, and evidence quality was graded using the GRADE approach. Data were analyzed using Review Manager and Stata, with subgroup and sensitivity analyses performed. Publication bias was evaluated using funnel plots and Egger`s test.

Results
Seven randomized controlled trials with 199 male athletes were included. The overall risk of bias was moderate, and evidence quality was low. Flywheel resistance training (FRT) significantly improved countermovement jump (CMJ) height (SMD = 0.46, p < 0.01) and had a small positive effect on linear sprint performance (SMD = -0.38, p = 0.02). Subgroup analyses indicated that CMJ performance improved with training programs consisting of more than 12 sessions, a duration of 5-10 weeks, and a training frequency of less than twice per week. No significant subgroup effects were observed for sprint performance. Sensitivity analyses confirmed the robustness of the results, and no publication bias was detected.

Conclusion
Compared with TRT, FRT is more effective in enhancing CMJ performance and linear sprint speeds over specific distances in male team-sport athletes during the in-season. Training protocols characterized by low frequency (<= 2 sessions per week) and a total of around 12 sessions appear to facilitate better athletic adaptations. Future research should include female athletes and investigate long-term interventions to further refine the application strategies of FRT in in-season training.]]></content:encoded>

      <content:encoded><![CDATA[The ability to change direction is crucial in soccer; however, evidence regarding acute intervention methods remains limited. Transcranial direct current stimulation (tDCS), a noninvasive brain modulation technique, has already been shown to enhance muscle function and athletic performance. Still, its influence on athletes` change-of-direction skills—especially at different turning angles—has not been fully clarified. In this study, thirteen male collegiate soccer players were divided into two groups: an experimental group receiving real stimulation and a control group receiving sham stimulation. The experimental group underwent twenty minutes of bilateral anodal tDCS over the primary motor cortex at 2 mA. tDCS significantly improved 45° COD performance (p = 0.027), while no changes were observed at 90°. Electromyography results provided further detail: during 45° turns, the integrated EMG values of the vastus lateralis increased significantly (p = 0.021), and during 90° turns, the root mean square values of the vastus medialis also rose significantly (p = 0.047). Altogether, these findings suggest that tDCS can act as an effective acute intervention to improve athletes` agility in direction changes, offering a practical edge for performance enhancement. This study was prospectively registered in the Chinese Clinical Trial Registry (ChiCTR290251, October 15, 2025).]]></content:encoded>

Methods
Sports injuries remain a major concern for athletes and fitness enthusiasts, affecting performance and long-term well-being. Effective prediction and prevention strategies are critical for reducing injury incidence. This study investigates the predictive roles of movement restriction and body asymmetry in sports injury risk.

Results
Significant restrictions in knee and shoulder mobility were associated with increased injury risk. Notably, asymmetries in lower limb strength and flexibility were linked to higher rates of unilateral injuries. For example, a 10% increase in movement restriction corresponded to a 15% higher injury risk, while a 20% strength imbalance predicted a 30% increase. The leg strength imbalance ratio showed a moderate positive correlation with injury rates (r = 0.35, p = 0.03), while the gait symmetry index was negatively correlated (r = -0.42, p < 0.01).

Conclusions
Joint mobility and interlimb balance play critical roles in injury susceptibility. Targeted interventions such as personalized exercise regimens and movement retraining may help mitigate these biomechanical risk factors. Future research should explore sport-specific injury mechanisms and refine predictive models using real-time monitoring and machine learning approaches.]]></content:encoded>

      <content:encoded><![CDATA[Objective
This systematic review and meta-analysis aimed to quantify the risk of subsequent all-cause, recurrent concussion, upper extremity, and lower extremity injuries in athletes with a history of sport-related concussion.

Methods
Following PRISMA guidelines, cohort studies published from inception through August 2025 were retrieved from PubMed, Cochrane Library, Embase, Web of Science, and EBSCO. The methodological quality of included studies was evaluated using the Newcastle-Ottawa Scale (NOS). Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using random-effects models. Pre-specified subgroup and meta-regression analyses were conducted to investigate sources of heterogeneity, including injury timing, study design, sport type, and athlete competition level.

Results
Nineteen cohort studies involving 86,879 athletes were included. Athletes with a history of concussion had significantly higher odds of sustaining a subsequent all-cause injury (OR = 1.93; 95% CI = 1.39-2.68). The risk was most pronounced for recurrent concussion (OR = 3.06; 95% CI = 1.81-5.17), and was also significantly elevated for upper extremity (OR = 1.76; 95% CI = 1.10-2.81) and lower extremity injuries (OR = 1.49; 95% CI = 1.06-2.09). Given the high heterogeneity observed in the primary outcomes (I2 > 90%), the pooled effect sizes should be interpreted with caution as average associations across varying study contexts, rather than as precise predictions applicable to all settings. Subgroup analysis revealed that injury risk was statistically significant in studies with follow-up periods beyond six months (OR = 1.94) but not for shorter durations. The association was strongest and statistically significant among college athletes (OR = 2.29; 95% CI = 1.53-3.44), while estimates for professional and high school athletes were not significant. Meta-regression identified sport type as a significant moderator of injury risk (p = 0.038).

Conclusion
A history of concussion significantly increases the risk of subsequent injuries, with the odds being highest for recurrent concussion. The persistence of this risk beyond six months suggests that clinical recovery does not equate to full functional recovery. These findings underscore the need for enhanced return-to-play protocols that incorporate objective functional assessments and targeted rehabilitation to mitigate the heightened vulnerability to injury in post-concussed athletes.]]></content:encoded>

      <content:encoded><![CDATA[Background
Blood flow restriction (BFR) has gained interest in its application in exercise and potential benefits. This study aimed to investigate the effects of low-load, low-frequency BFR training compared with traditional high-intensity training on soccer-related performance outcomes and injury indicators in amateur athletes.

Methods
Twenty licensed male soccer players competing in a university-level league were randomized to either a BFR group (n = 10, 22.3 ± 1.3 years) or a control group (n = 10, 22.1 ± 1.8 years) for 6 weeks of training. Pre- and post-intervention assessments included muscle strength-endurance (isokinetic dynamometer), power (vertical jump test), aerobic endurance (Yo-Yo level 1 test), speed-agility (T test, Y-shaped reactive agility test), dynamic balance (Y test), thigh circumference, fatigue (blood lactate, Borg scale), and sportive self-confidence. Perceived change (GROC) was assessed post-intervention. Injury data were tracked for six months following the intervention.

Results
BFR improved dominant limb flexor strength, endurance, aerobic capacity, speed, and dynamic balance (p < 0.05, Cohen`s d: 0.40-1.06). Both groups showed gains in power, agility, and self-confidence (p < 0.05, Cohen`s d: BFR = 0.51-1.35; Control = 0.40-1.01), whereas hypertrophy (p = 0.026, PEta2 = 0.24) and GROC scores (p = 0.022) were significantly higher in the BFR group than in the control group. No differences were observed in terms of fatigue. The standard error of the mean values for significant within-group changes ranged from 0.03 to 8.64. Although the injury rate was lower in the BFR group, this trend was not significant (p > 0.05).

Conclusion
BFR appears to be a feasible, load-efficient, and well-tolerated approach to improve performance parameters in amateur soccer players, with potential benefits for lower-limb injury prevention.]]></content:encoded>

      <content:encoded><![CDATA[Background
This study seeks to contribute uniquely to the underexplored field of traditional Turkish archery by objectively examining the effects of music on physiological and technical parameters, including heart rate, shooting duration, shooting frequency, shooting performance, and draw biomechanics.

Methods
In this context, the study investigated the effects of rhythmic diversity on parameters such as heart rate, shooting frequency, shooting duration, shooting accuracy, and draw biomechanics. The participants of the study were 14 students studying at Bayburt University and interested in traditional Turkish archery. The athletes were assigned shooting tasks initially without music and then with music at different BPM ranges (Downbeat, Medium, and Upbeat). Various biometric and athletic data were recorded before and after the music. During the practice, the effects of downbeat, medium, and upbeat tempo music on different physiological reactions and performance variables were analyzed. A Polar watch, a digital stopwatch, and a high-resolution camera were used during the shooting sessions. Kinovea software was used to measure draw biomechanics.

Results
The study results revealed significant differences in heart rate between shots performed with music at different rhythms, with higher average values found with higher tempo music (p < 0.05; F = 13.842). Regarding shot duration (p < 0.05; F = 9.212) and shooting frequency (p < 0.05; F = 8.763), shots performed without music took longer, while shots performed with moderate tempo music were found to be the most efficient. Participants scored significantly higher for shots performed with both no music (42.09) and medium rhythm music (44.71) than for shots performed with downbeat and upbeat tempo music (p < 0.05; F = 9.826). However, no differences were found in the draw biomechanics that shape technical performance during shooting based on music type (p > 0.05; F = 0.968).

Conclusions
The findings indicate that while higher musical tempos elevate athletes` heart rates and reduce shooting duration and frequency, shooting performance is superior at moderate tempos compared to downbeat or upbeat tempos.]]></content:encoded>

      <content:encoded><![CDATA[Background
Volleyball requires repeated explosive actions, agility, and technical precision, demanding contributions from both aerobic and anaerobic energy systems. Time-efficient training methods such as resistance-based high intensity interval training (HIIT) and high intensity functional training (HIFT) have been proposed to enhance multidimensional performance in young athletes. However, direct comparisons of their effects in adolescent female volleyball players are limited.

Methods
Thirty-two licensed female volleyball players (aged 15-18 years) were randomly assigned to a resistance-based HIIT group (n = 10), a HIFT group (n = 11), or a control group (n = 11). The training interventions lasted 12 weeks with two supervised sessions per week, in addition to regular volleyball practice. The HIIT program consisted of progressive resistance-based high intensity intervals performed at 85-95% HRmax, while the HIFT program comprised multimodal circuit-style functional exercises performed at comparable intensities (~ 85-95% HRmax). Performance assessments were conducted pre- and post-intervention and included the countermovement jump (CMJ), standing long jump (SLJ), medicine ball throw (MBT), pro-agility test, 20 m sprint, repeated sprint fatigue index (RSI), volleyball skill test, Yo-Yo IR1 distance, VO2max, blood lactate concentration, and maximal heart rate (MaxHR). Data were analyzed using a 3 × 2 mixed-model ANOVA with Tukey post hoc tests, and effect sizes were reported as Cohen`s d and partial eta squared (Etap²).

Results
Significant Group × Time interactions were observed for CMJ (F(2,29) = 9.14, p < 0.001, Etap²=0.39), SLJ (F(2,29) = 12.08, p < 0.001, Etap²=0.45), VO2max (F(2,29) = 11.53, p < 0.001, Etap²=0.44), MaxHR (F(2,29) = 3.56, p = 0.041, Etap²=0.20), and volleyball skill test (F(2,29) = 7.44, p = 0.002, Etap²=0.34). HIFT produced the greatest improvements in explosive power (CMJ Delta =+5.15 cm; SLJ Delta =+12.82 cm), RSI (Delta =-1.56), and volleyball skill performance (Delta =+13.18 points), with large effect sizes (d = 1.3-3.2). HIIT showed relatively greater improvements in aerobic capacity (VO2max Delta =+0.90 ml·kg-1·min-1) and endurance (d = 0.7-2.0). No significant between-group differences were observed for lactate.

Conclusions
Both resistance-based HIIT and HIFT proved effective in improving several physical and volleyball-specific performance components in adolescent female players. HIIT produced slightly greater gains in aerobic capacity, while HIFT showed larger numerical improvements in explosive strength, agility, and technical skill performance; however, these between-intervention differences were not statistically significant. Overall, the findings suggest that each modality offers complementary benefits, and integrating both HIIT and HIFT may provide a balanced conditioning approach for the holistic development of youth volleyball athletes.]]></content:encoded>

      <content:encoded><![CDATA[Background and aims
Return-to-play (RTP) readiness is a critical consideration for common baseball injuries, including after ulnar collateral ligament (UCL) injuries. UCL injuries, often resulting from repetitive throwing stress, can significantly impact an athlete`s career, requiring interventions ranging from nonoperative rehabilitation to surgical reconstruction. While RTP criteria for these injuries exist, they remain inconsistent across studies and clinical practice. Commonly reported RTP criteria include achieving pain-free range of motion and completion of progressive throwing distances. This systematic review aims to analyze and compare different RTP criteria for UCL injuries in baseball players.

Methods
This systematic review follows the PROSPERO protocol (CRD42024607322) and adheres to the PRISMA guidelines. Three independent reviewers conducted a comprehensive search across PubMed, Scopus, and Embase to identify relevant studies. Search results were imported into Covidence for systematic screening and data management. Any disagreements or uncertainties in study selection were resolved by a fourth reviewer to ensure consistency and accuracy. After full-text screening and eligibility assessment, 18 articles were included for data extraction.

Results
Eighteen studies on UCL injuries (n = 2887) were included. UCL injuries predominantly affected professional or collegiate pitchers in baseball and were linked to valgus stress during high-velocity throwing. Reported rehabilitation protocols varied, ranging from brief immobilization followed by progressive range-of-motion and throwing programs to structured three-month conservative interventions before considering surgery. RTP was assessed using objective performance metrics such as earned run average (ERA), walks and hits per inning pitched (WHIP), and advanced metrics like Wins Above Replacement (WAR). RTP rates ranged from 80% to 91%, with most players returning to their pre-injury level of competition. Some studies reported incomplete protocol adherence due to pain, lack of motivation, or pursuit of alternative treatments.

Conclusion
This review highlights inconsistencies and differences in RTP criteria for UCL injuries. Key influencing factors include treatment type, competition level, and psychological readiness. Although metrics such as ERA, WHIP, and imaging findings are frequently used, their application lacks uniformity. Standardized, multidisciplinary RTP protocols integrating physical, imaging, and psychological components are essential to guide safe and objective return-to-sport decisions.]]></content:encoded>

      <content:encoded><![CDATA[This study conducted a systematic review with meta-analysis to investigate the effects of high-intensity interval training (HIIT) on aerobic capacity and performance in trained athletes. The data sources utilized were PubMed, EBSCO, and Web of Science. Eligibility included trained athletes, encompassing amateur, elite, or professional male and female participants, with no age restrictions. Outcome measures include aerobic capacity and performance. Methodological quality was assessed using the Cochrane, Bias risk assessment tool. The search identified 4,289 titles, with 18 articles eligible for the review and meta-analysis. The results showed that HIIT significantly improved VO2max (SMD: 1.11, 95% CI: 0.48, 1.74; heterogeneity p < 0.1) and VO2peak (MD: 0.52, 95% CI: 0.08, 0.97; heterogeneity p < 0.1) in trained athletes, indicating a remarkable effect of HIIT in enhancing aerobic capacity. In terms of athletic performance, HIIT significantly improved speed (MD: -0.72, 95% CI: -1.41, -0.03; heterogeneity p < 0.1) and agility (MD: -0.93, 95% CI: -1.79, -0.06; heterogeneity p < 0.1). However, no significant effects of HIIT were observed on HRmax, jump, and power, suggesting that its main advantages are focused on cardiopulmonary endurance and efficiency-related indicators rather than maximal strength or explosive power.]]></content:encoded>

      <content:encoded><![CDATA[Purpose
This study examines (i) the relationships between training load and sleep quality parameters of deaf handball players and (ii) their weekly differences. Athletes went through four different camp periods in 45-day camp periods.

Methods
Sleep quality and training load data were obtained from athletes in four separate camp periods, each lasting 10-12 days. Spearman correlation analysis was performed to determine the relationship between Training Load and Sleep Quality. Kruskal-Wallis test was used to determine the differences in sleep quality and training load parameters between blocks. Dunn`s post hoc analysis was performed to determine which block caused the differences.

Results
As a result of the analyses, there are statistically significant differences between both training load and sleep quality between weeks and between weeks in terms of sleep falling asleep and sleep quality [How long did it take to fall asleep (minutes) (p = 0.001: Eta²p: 0.057)]. As a result of Spearman correlation analysis, no statistically significant relationship was detected between training load and sleep quality parameters. No statistically significant relationship was found between the sleep quality of handball players and their training load values. There are statistically significant differences in sleep quality and training load values between weeks.

Conclusions
The analysis reveals statistically significant differences in training load and sleep quality between weeks, as well as between the times of falling asleep and sleep quality within weeks.]]></content:encoded>

      <content:encoded><![CDATA[This article investigates biathlon`s physiological demands, integrating maximal endurance with precision shooting as athletes enter the range at ~85% HRmax, necessitating rapid cardiorespiratory stabilization (Hoffman & Street, 1992). It reports empirical data on per-shot breathing patterns, emphasizing their architecture, temporal stability, and correlations with hit accuracy. Such research on biathletes` ventilatory control during shooting remains markedly underrepresented despite its mechanistic relevance. In precision rifle sports, shots optimally coincide with short apnoea to attenuate somatic motion and enhance sight alignment.]]></content:encoded>

      <content:encoded><![CDATA[This article summarizes how skiing speed, shooting accuracy and range time contribute to biathlon performance across formats. Skiing speed is particularly important in sprint events for lower-ranked athletes, whereas shooting accuracy is decisive for top performers and even more critical in individual races due to time penalties per miss. In pursuit and mass start, final standing shooting largely determines success, with prior sprint performance influencing pursuits and sufficient skiing speed essential for podium contention. In relays, strategic team selection is crucial, with men`s results more influenced by skiing speed and women`s by range efficiency.]]></content:encoded>

      <content:encoded><![CDATA[The inclusion of Coastal Rowing Beach Sprints in the 2028 Olympic program is reshaping the sport by mainstreaming racing in challenging and unpredictable open-water environments, characterized by waves, sharp turns, and constantly changing conditions. Despite its rapid growth in popularity, further systematic research on how to enhance performance, excitement and enjoyment while maintaining athlete safety remains limited. As a result, athletes, event organisers, equipment manufacturers, and governing bodies face a steep learning curve. This work highlights the key technical and safety aspects of the discipline that warrant further development and proposes conceptual solutions grounded in science and engineering. It also outlines a preliminary roadmap for future research aimed at advancing safety, performance, and the overall athlete and spectator experience in coastal rowing—an endeavour that demands collaboration between the sporting, scientific, and engineering communities.]]></content:encoded>

      <content:encoded><![CDATA[Sports analytics has become increasingly central to applied sport science, yet its conceptual development remains unevenly theorized. This study mapped the evolution of sports analytics research from 2015 to 2025 using a Scopus-based bibliometric analysis of 1,211 documents. Descriptive bibliometrics, co-authorship analysis, country collaboration mapping, keyword co-occurrence analysis, trend-topic analysis, bibliographic coupling, and co-citation analysis were used to examine the field`s development, conceptual structure, and intellectual foundations. Findings show that sports analytics has expanded rapidly and is increasingly organized around athlete monitoring, performance analysis, machine learning, training load, artificial intelligence, and decision support. The literature reflects a shift from descriptive measurement toward predictive and computationally mediated forms of applied sport science. However, this growth also exposes unresolved tensions involving model interpretability, data quality, ethical governance, and the translation of analytics into practice. To address this, the study proposes a responsible and integrative framework that positions sports analytics as an interconnected system of data capture, computational processing, human interpretation, applied performance action, and ethical governance. The review argues that sports analytics becomes meaningful only when technological sophistication is aligned with valid, interpretable, and athlete-centred decision-making.]]></content:encoded>

      <content:encoded><![CDATA[The study examined the impact of technical-tactical attacking indicators on futsal performance and differences between players and clubs by performance level. It included 111 elite players from the 1st Croatian Futsal League who played at least 600 seconds in the 2020-2021 season. Competitive performance was rated on a 1-5 Likert scale based on players` and clubs` competitive performance index (PCPI:1-3; CCPI:1-3). Indicators included ball receptions and ACTIVE and PASSIVE passes. Multiple regression (p < .05) and ANOVA with Bonferroni post-hoc were used for statistical analysis and group comparisons. Significant effect (b* = -0.20, p = .047) was found between PASSIVE (UN) and CCPI. On the other hand, ACTIVE (S) (b* = 0.24, p = .031) and PASSIVE (UN) (b* = -0.23, p = .016) were significantly associated with PCPI. CCPI3 significantly differed in RECEIVE (S) compared to CCPI1 / CCPI2 (20.59 vs. 16.53 / 16.40). CCPI3 performed significantly higher in PASSIVE (S) compared to CCPI1 and CCPI2 (19.33 vs. 14.25/14.32). PCPI3 also differed from PCPI1 and PCPI2 in RECEIVE (S) and PASSIVE (S). PASSIVE (UN) negatively affects both team and individual performance, while ACTIVE (S) are linked positively to competitive performance. Additionally, clubs and players with better ball distribution (RECEIVE (S) and PASSIVE (S)) are more likely to be successful.]]></content:encoded>

      <content:encoded><![CDATA[Running-related knee injuries are common in long-distance runners and may lead to persistent biomechanical adaptations even after return to sport. This study aimed to compare spatiotemporal parameters of the running gait cycle between long-distance runners with and without a history of knee injury during incremental treadmill running. Thirty male long-distance recreational runners (15 with previous knee injury and 15 controls) were assessed using three-dimensional motion capture at 9, 11, and 13 km/h. Temporal variables included stride time, stance time, swing time, phase distribution, and cadence. Mixed-model repeated measures analyses and Mann-Whitney U tests were applied (p < .05). No significant main effects or interactions were observed, indicating a preserved global temporal organization across speeds. However, runners with a history of injury demonstrated greater stance time at 9 km/h (right limb) and 11 km/h (left limb). These findings suggest the presence of subtle, speed-dependent adaptations in temporal running mechanics, particularly during the stance phase. Such localized adjustments may be relevant for understanding injury recurrence and guiding biomechanical assessment in running populations. injury recurrence and for guiding biomechanical assessment in running populations.]]></content:encoded>

      <content:encoded><![CDATA[Objectives
Sport climbing presents an exceptionally interesting research field for issues related to anxiety and stress. This discipline, classified as an extreme sport, requires participants not only to be in very good physical condition, but also to be mentally resilient and able to cope with high emotional pressure. Theoretical models of self-efficacy and psychophysiological load suggest that individual characteristics (e.g., gender, BMI) and situational factors (e.g., belay type) may shape climbers` emotional responses by influencing perceived control, physical strain, and risk appraisal. The aim of the study was to assess the level of anxiety experienced by sport climbers.

Design
This was a cross-sectional study.

Method
The study was performed among 100 people practising sport climbing on climbing walls in three large Polish cities. The study was conducted between November 2023 and January 2024. The research was divided into three parts: a structured interview, measurement of anthropometric and vital signs parameters before and after climbing. A self-designed survey questionnaire and a standardised tool, i.e. STAI X-1 and STAI X-2, were used to collect empirical data.

Results
The study showed that climbers experienced significantly more anxiety during lead climbing (40.1 ± 9.2) than when top-rope climbing (33.1 ± 6.3). Anxiety as a state during climbing with a bottom belay was observed at a high level in 46% of the participants.

Conclusions
Most participants experienced anxiety during sport climbing. Their anxiety was reflected by physiological changes. The determining factors for the participants` feelings of anxiety during climbing were gender, BMI and climbing method. In the study group, climbers experienced significantly higher levels of anxiety when climbing with a lead climbing than a top-rope climbing.]]></content:encoded>
