Abstract	From the biomechanical aspect, explosive strength is required in athletic sport disciplines like long jumping, high jumping and throwing. Particularly, it is required in technical gestures like take off and landing in vertical jumping. The aims of the current research were to determine difference in the explosive strength of lower extremities between: 1) athletes and non-athletes; 2) the participants in relation to gender; 3) athletes in relation to their sport activity. The sample of participants consisted of 240 individuals (120 athletes and 120 non-athletes, i.e., 106 male and 134 female participants, respectively), chosen from the population of high-school students. All of the participants performed five CMJ without the arm swing in order to determine, by using the Myotest device (Sion, Switzerland) the following variables of explosive strength: Height (expressed in cm); Power (expressed in W/kg); Force (expressed in N/kg) and Velocity (expressed in cm/s). For the statistical analysis and interpretation of the results, the statistical package SPSS 13.0 was used. The results were expressed by descriptive statistics, while in order to calculate the statistically significant difference in the explosive strength of lower extremities between participants in relation to their sport activity and gender, the t-test, ANOVA and POST HOC (LSD) test were used. The best results for the variables Height, Power, and Velocity were achieved by basketball players, while the best results for variable Force were achieved by non-athletes. In general, athletes and male participants performed better on functional tests than non-athletes and female participants, respectively. The statistically significant differences were determined between groups of athletes for all the variables, except for the variable Force.

BUBANJ, M. ŽIVKOVIĆ, R. STANKOVIĆ, D. ŽIVKOVIĆ, R. BUBANJ, A. DIMIĆ supposed that a yearlong basketball practice represents a good basis for the development of superior jumping abilities in basketball players, in comparison to other athletes in the current research. In general, the results were similar when the athletes and non-athletes, who participated in the current research, were compared: certain sport activities contribute to the difference in explosive strength of the lower extremities.
