Experimental design: Thirty adolescent boys aged between 14 to 16 years served as subjects for test validation. The subjects completed field test to determine arm explosive power, leg explosive power and muscular power.

Methods: The subjects was randomly assigned to two equal groups (n=15). Group- I underwent isometric strength training (ISTG) and Group - II was acted as control group (CG). The respective training was given to the experimental group for 3 days per week (Monday, Wednesday and Friday) for the period of eight weeks. The control group was not be given any sort of training except their routine work. The physical parameters were arm explosive power (medicine ball throw), leg explosive power (standing broad jump) and muscular power (sit-ups) were measured before and after training period. The data collected from the subjects was statistically analyzed with‘t’ ratio to find out significant improvement if any at 0.05 level of confidence.

Results: The results of the vertical jump, leg explosive power and muscular power improved significantly due to impact of isometric strength training with the limitations of ( diet, climate, life style) status and previous training the result of the present study coincide findings of the investigation done by different experts in the field of sports sciences. Isometric strength training significantly improved vertical jump, leg explosive power and muscular power of school level adolescent basketball players.
