Abstract

The purpose of this study was to compare the effects of a six week training period of combined plyometric and resistance training (PRT, n = 13) or resistance training alone (RT, n = 14) on fitness performance in boys (12-15 yr). The RT group performed static stretching exercises followed by resistance training whereas the PRT group performed plyometric exercises followed by the same resistance training program. The training duration per session for both groups was 90 min. At baseline and after training all participants were tested on the vertical jump, long jump, ...

<.05, with the PRT group making significantly greater improvements in performance than RT. There were no significant interaction effects between groups for the vertical jump, 9.1 m sprint and flexibility, [F.sub.(1,25)] = 3.6, 0.1, and 1.6, respectively, p>
