Abstract

The aim: The aim of this study was to validate the 12-week effect of the experimental program on the performance of segmental velocity and explosive strength of the lower and upper extremities in adolescents. Methods: The research was carried out in a sample of 220 male entities aged 15 years ± 6 months, high school students in the municipalities of Kumanovo and Likova, in the Republic of North Macedonia. The sample of 220 subjects was divided into 2 groups: Group A: Experimental (EG, n=115, height 168.6, weight 60.4, IMT 21.09) and Group B: Control (CG, n=105, height 168.1, weight 56.8, IMT 20.8) ). Subjects from the experimental group underwent a 12-week experimental program, while the control group did not follow any adequate program, except for 2 regular hours during the week in the subject of physical education. To evaluate the performance of segmental speed and explosive strength of the lower and upper extremities, we used foot tapping, hand tapping, standing long jump, vertical jump, medicine ball chest throw and seated medicine ball throw tests. The study had a longitudinal character and lasted 12 weeks, with 36 hours of training or 3 hours during the week and 2 hours from the subject of physical education.Results: The results of the study after the application of the experimental model, in the final measurements, show that all the variables of the explosive force of the lower and upper extremities have statistically significant differences (p=0.05), between the control and the experimental group, in favor of the experimental group, while the segmental velocity variables have no significant differences. According to data from the univariate analysis of variance (ANOVA), in the initial measurements, no significant differences appeared in any test used in this study. While according to the data from the univariate analysis of covariance (ANCOVA), in the final measurements, we find that the data system in the space of physical fitness has statistically significant differences in the vertical jump (VJ) (p=0.019), medicine ball chest throw (MBCHTH) (p=0.026), seated medicine ball throw (SMBTH) (p=0.038) and standing long jump (SLJ) (P=0.047), while segmental speed parameters have no significant statistical differences. Conclusion: All the tests are in favor of the experimental group, which can prove that this experimental model, with 3 extra hours per week, in a 12-week period, has a positive effect on the development of the explosive strength performance of the lower and upper extremities in adolescent. Practical application: These findings provide further evidence for the improvement and enhancement of physical fitness performance through the implementation of the experimental program model in the adolescents who attended this experiment.
