Examination of contractile characterists of flexor muscles of the fingers is equally important factor in the functional evaluation of the arm, i.e. the hand, as it is in the purpose of the evaluation of development of physical abilities levels and preparation of athletes. The function of the hand presents a permanently active field of a scientific research for the purpose of expanding the fundus of knowledge, but of perfecting the procedure of testing and for diagnostical purposes as well. The aim of this research is the determination of differences in contractile wrestlers hand muscles abilits and control group of young and moderately physically active male people. For the need of this research, isometric dynamometry and standardized test . hand grip methods have been used. Fiftynine respondents, aged between 19 and 34 years old have taken part in this research, out of which 28 were wrestlers and 31 were respondents from the control group. For determination of the differences between sets of variables, a multivariate test (MANOVA) was used, whereas for determination of the differences between pairs of single variables, the t test for independent samples was used. By conducting the analysis, the conclusion that wrestlers have statistically significantly higher level of maximum and explosive strength, but not the endurance when it comes to the force of a hand grip in comparison to the absolute values, but statistically significantly higher explosive force of a hand grip from the aspect of relative values compared to control group has was drawn. Higher level of absolute force does not carry within itself the increase of other muscle characteristics (explosive force and endurance) unless the muscle does not adapt to such kind of activity by specific way of training, whereas the lesser absolute force surely requires less energy requirements and lesser need for the oxygen when it comes to realization of maintaining the hand gripfs contractile force on 50 per cent Fmax level for the longest time interval possible.
