Comparison of Post Isometric Relaxation and Post Facilitation Stretching on Hamstring Muscle Flexibility

The goal of this randomized clinical trial is to check the effectiveness of post isometric relaxation and post facilitation stretching on hamstring muscle flexibility in collegiate athletes.The main question it aims to answer is:To compare the post isometric relaxation and post facilitation stretching techniques on hamstring muscle flexibility in collegiate athletes Participants will be divided in two groups,Group-A will be treated with baseline treatment of heating for 15min and rehab protocol post isometric relaxation in which 3-5 repetitions for 7-10 seconds hold in each session for three sessions per week in alternate days for four weeks.Group-B will be treated with baseline treatment of heating for 15min and rehab protocol post facilitation in which 3-5 repetitions for 7-10 seconds hold in each session for three sessions per week in alternate days for four weeks.
