Objective of the study was to identify the parameters of strength fitness of athletes of different skill levels from various team sports and conduct a comparative analysis of the data obtained. Methods and structure of the study. The following research methods were applied: theoretical analysis; testing; mathematical statistics. Sampled for the study were 117 handball players, 118 volleyball players, 114 basketball players, and 127 football players (qualified from Class III to Masters of Sports). The relative strength rates in the subjects` muscle groups were determined using the generally accepted method of B.M. Rybalko and B.M. Abalakov`s test (dynamometry). Results and conclusions. The experimental research under the supervision of Professor G.N. Maksimenko and further comparative analysis of the data obtained revealed the relative strength indices in different muscle groups of volleyball, handball, basketball, and football players with sports qualifications from Class III to Masters of Sports. The sports progress from Class III to Masters of Sports in the studied groups was accompanied by a statistically significant increase in the athletes` relative strength rates (and hence, absolute strength rates). The highest aggregate values of relative strength in the 5 leg muscle groups were recorded in the Masters of Sport in football (6.04±0.04 kg). Simultaneously with the identification of the parameters of development of strength qualities of various muscle groups, we conducted a comparative analysis of the data obtained in the athletes from various team sports with sports qualifications from Class III to Masters of Sports. The findings conform to the modern scientific idea that sports progress and improvement of competitive performance in team sports largely depends on the level of development of strength qualities of individual muscle groups [3, 4]. The growth of sports skills is accompanied by a statistically significant increase in the strength of particular muscle groups.
