Type  Name  Details 
Intervention  STATIC STRETCHING ISOMETRIC RELAXATION IN ATHLETES   The procedure begins with the screening of 50 individuals for inclusion criteria, then the procedure will be explained and an informed consent form will be taken from the individuals. In the first phase pre intervention assessment taken in which the individuals will be divided into two different groups athletic and non-athletic and both will be performing the SLR (straight leg raise test), AKE (Active knee extension test) and Sit and reach test. Then subject will perform warm up exercise in room with static stretching and isometric relaxation followed up by twice a week for duration of four week. In the second phase post assessment taken with the same technique SLR (straight leg raise), AKE (Active knee extension test) and Sit and reach test. STUDY PROTOCOL: Subjects will perform warm up exercise in room then they perform the static stretching and isometric relaxation. Static Stretching: The subjects will be instructed to attain lengthy sitting position with both knees straight, lift their arms, bend at the pelvis, and try to touch their toes. The stretch will be hold for 30 seconds, then performed four times, interspersed with 30-second rest intervals. Isometric relaxation: The subjects will be asked for kneeling, stretching their dominant leg straight forward while extending their knee. Then we will advise them to bend at the pelvis to feel a stretch in their hamstrings, press their heel on the ground for ten seconds, and then relax. This will be performing for five times, pausing for ten seconds in between

Brief Summary   This study involves the static stretching and isometric relaxation to determine the hamstring flexibility in athletes and non- athletes. The hamstrings are essential muscles that are crucial for the function of the lower limbs. A set of muscles called the hamstrings controls the movement of the hip and knee joints as well as the alignment of the pelvis and spine. These muscles are essential for a variety of tasks, including walking and intense sports. The procedure begins with the screening of 50 individuals for inclusion criteria, then the procedure will be explained and informed consent form will be taken from the individuals. In the first phase pre intervention assessment taken in which the individuals will be divided into two different groups athletic and non-athletic and both will be performing the SLR (straight leg raise test), AKE (Active knee extension test) and Sit and reach test. Then subject will perform warm up exercise in room with static stretching and isometric relaxation followed up by twice a week for duration of four week. In the second phase post assessment taken with the same technique SLR (straight leg raise), AKE (Active knee extension test) and Sit and reach test.
