Abstract


This study aims at identifying the impact of a training program using machines and free weights on developing the maximum muscular power among bodybuilders. The study sample consisted of (12) bodybuilders, who were divided into two identical groups, with (6) bodybuilders in each group. The sample individuals were randomly chosen from Turbo Gym Center for bodybuilding. The study used the experimental approach using the method of experimental design for two experimental groups for the pre and post measurement. The study used the means, standard deviations, Wilcoxon Signed Pairs Method, accompanying variance analysis and one-way variance analysis. The results revealed that there are statistically significant differences at (α≤0.05) between the pre and post measurement using machines on developing the maximum muscular power in favor of the post measurement among bodybuilders. The results revealed that there are statistically significant differences at (α≤0.05) between the pre and post measurement using free weights on developing the maximum muscular power in favor of the post measurement among bodybuilders, while the results showed that there are no statistically significant differences at (α≤0.05) in the post measurement between the group of machines and the group of free weights on developing the maximum muscular power in favor of the post measurement among bodybuilders.

In the light of the results, the researchers recommended the necessity of using the two training programs and integrating them as a method to improve the maximum muscular power among bodybuilders in Jordan and not depending on a single training method for a long period of time.
