EFFECTIVENESS OF BACK SQUAT TRAINING WITH PLYOMETRIC EXERCISE PROGRAM ON LEG POWER AND SPRINT PERFORMANCE IN YOUNG ADULT SPRINTERS.

ABSTRACT Background: Leg power and sprint performance are important skills for sprinters. Standing broad jump test and 30 meter sorint test are the outcome tool used to measure the leg power and sprinting performance. Purpose: To find the effectiveness of back squat training with plyometric exercise program on leg power and sprint performance in young adult sprinters. Method: The study design was an experimental study, 30 male sprinters were selected from the Sri Venkateswaraa College of Physiotherapy. They were allocated divided into two groups. For Group A (n=15) Back squat training and plyometric training. For Group B (n=15) plyometric training alone, three sessions in a week for 6 weeks. The outcome measure standing Broad jump test, 30 meter sprint test were measured in pre and post-test for 6 weeks. Results: Data analysis was done by unpaired 't' test and paired 't' tost for the between group and within the group analysis respectively. The statistical analysis done with unpaired 't' test within the Group A and Group B analysis shown significance (p<0.0001). Which shows that Group A must be significant than Group B, it have been concluded that Group A shows improvement in leg power, sprint performance in sprinters than Group B. Conclusion: This study concludes that the Back squat training along with plyometric training (Group A) shows more significant improvement in leg power, sprint performance among sprinters when compared with conventional training (Group B).
