This study compared the effects of a six week training period of combined plyometric and resistance training (PRT) or resistance training alone (RT) on fitness performance in boys. Healthy boys (N = 14, 12-14 yr) were divided into two treatment groups to train twice per week for six weeks: RT (N = 7) or PRT (N=7). 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. Both training sessions lasted 90 minutes. All Ss were pre- and post- tested on the vertical jump (VJ), long jump (LJ), medicine ball toss (MB), 10-yd. sprint (SP), pro-agility shuttle run (PRO), and flexibility (FX).

The PRT group improved significantly more than the RT group in long jump, medicine ball toss, and pro-agility shuttle run. There were so differences in vertical jump, 10-yd sprint, or flexibility.

Implication. Combined plyometric and resistance training program may be more beneficial than resistance training alone for enhancing upper and lower body power in boys.
