The aim of this study was to determine and to compare the effects of different exercise programs: exercise program with medicine ball and developmental gymnastics program, which was applied in the additional physical activity for 12 weeks, on the transformation of fitness parameters of the experimental groups. The study involved 60 (30 girls) respondents, average age 12 years, who were divided into three groups: the first experimental group (E1; n = 20) which implemented an exercise program with medicine ball, the second experimental group (E2; n = 20) which implemented a program of developmental gymnastics and a control group (K; n = 20) which conducted regular physical education classes. Fitness parameters were evaluated by the following variables: body height, body weight, body mass index, squat jump, long jump, bent-arm hang, sit-ups, push-ups, sprint 30m, T-test, hand grip, shutlle run 20m, medicine ball throw tests, sum of skinfolds, percentage of body fat, mass of body fat, muscle mass, percentage of lean body mass. For all tests, central and distribution parameters were calculated. The normality of the distribution of variables was tested by the Kolmogorov-Smirnov test. Multivariate analysis of variance (MANOVA) and two-factor univariate analysis of variance (ANOVA) were used to determine the significance of differences between groups in the initial and final testing. A t-test for dependent samples was applied to determine the differences between the initial and final measurements. The magnitude of the effects within each group was determined using the Cohen effect size (ES). Multivariate (MANCOVA) and univariate covariance analysis (ANCOVA) were used to determine the effects of experimental programs. The obtained data were processed in the statistical package SPSS 20. (Statictical Package for Social Sciencess, v20.0). Compared to the initial state, the results showed statistically significant differences between groups at the final measurement (p <0.05), in most tests of fitness abilities in favor of experimental groups, while from theДокторска дисертацијаРадомир Пржуљ Страна 7body composition space the results showed statistically significant differences in muscle mass (p=0.045) and the sum of skin folds (p=0.010). Based on these results, it can be concluded that exercise with medicine ball and developmental gymnastics with the instructions of qualified experts can lead to significant improvements in selected fitness parameters of school children and youth, and prove to be an effective method for promoting physical activity.
