Efficacy of resisted sled sprint training compared with unresisted sprint training on acceleration and sprint performance in rugby players: An 8-week randomized controlled trial
(Wirksamkeit des Sprinttrainings mit Widerstand im Vergleich zum Sprinttraining ohne Widerstand auf die Beschleunigung und Sprintleistung von Rugbyspielern: Eine randomisierte, kontrollierte 8-Wochen-Studie)
Purpose: To compare the effects between resisted sled sprint training (RSS) and unresisted sprint training (URS) on sprint and acceleration performance, vertical jump, and maximal strength during an 8-week period of preseason training.
Methods: Twenty-six recreational active rugby players were randomly divided into either RSS or URS training groups and then performed 8 weeks of training, 2 sessions/wk of sprint-specific training program. The RSS group performed sprints by towing a sled overloaded with 12.6% of body mass for 2 of the 3 sets of 3 × 20-m sprints, plus one set was carried out with unresisted modality. The URS groups performed 3 sets of 3 × 20-m unresisted sprints. The measures of 10- and 30-m sprint times, vertical jump, and 3-repetition-maximum (3-RM) squat tests were performed at baseline and after 8 weeks.
Results: Ten- and 30-m sprint times (P < .05 and np^2 > .44) improved significantly more in RSS than in URS. Both groups improved significantly in vertical jump and 3-RM squat tests; however, no significant differences (P > .1 and np^2 < .11) between groups were found.
Conclusions: Our findings indicate that an 8-week program of RSS is more effective than URS for enhancing sprint time performance in male recreational active rugby players. In addition, these data suggest that a sled overload corresponding to 12.6% of body mass can induce positive effects on both acceleration and speed performance in recreational active rugby players.
