<p>Purpose: comparative study of indicators of hands’ strength and endurance at athletes of arm sport of different skill levels. Material: the study involved 50 athletes. Athletes were divided into two groups: 1 - 15 athletes with high skill levels (age 25,25 ± 0,62 years) and 2 - 35 athletes and fans of mass categories (age 22,21 ± 0,35 years). Results: it is shown that the results of carpal dynamometry right and left hands were significantly higher in group 1 (respectively: 60,50 ± 0,91 kg and 53,75 ± 0,83 kg against 52,35 ± 0,51 kg and 48 53 ± 0,46 kg). Strength endurance was significantly higher in group 2 (respectively: 32,97 ± 0,61 sec 33,09 ± 0,62 sec against 23,78 ± 0,85 sec and 24,66 ± 0,78 sec). Found that carpal dynamometry has a maximum contribution to the system (in group 1 for the right hand - 18.17, for the left - 23.50, in group 2 - 7.44 and 7.10). Correlation coefficients dynamometry in group 1 were significantly higher. Strength endurance had almost no connection with the study of reliable performance. Conclusions: it is proved that the level of carpal dynamometry is an important informative and adequate criterion. This indicator is characterized by a maximum contribution backbone.</p
