Floss band made of natural rubber, black in color and 4" in width will be wrapped around the thigh, starting from the distally to superiorly with an overlap of 50%. Perform exercises:

• Multi-directional leg swing

Perform exercises without floss band.

• Multi-directional leg swing

Floss band involves wrapping a band made of natural rubber around the targeted joint or muscle for 1-3 minutes through active movement. The mechanism behind flossing is thought to have a "three-fold effect", compression may stimulate the mechanoreceptors of the underlying fascia layer which causes the hyperemia of the targeted tissue, and leads to increased blood flow.

This intervention was applied in addition to dynamic stretching which involved 3 types of dynamic stretches. These stretches were applied through multidirectional (anteromedial, anterior, and anterolateral) leg swings specifically for the Hamstring muscle. It was performed in 3 sets of 15 repetitions with 30 seconds of rest between each exercise.

Universal goniometer was used to measure SLR angle.

Universal goniometer was used to measure AKE angle.

A ruler was used to measure Sit and Reach Test Score.

Creatine-kinase is a type of enzyme that muscle cell need to function, small amount of CK is present in our blood but high level indicates muscle injury. CK-MM is the substance rises when skeletal muscle is injured. This test is valid(r=0.58) and reliable (r=0.87) to check the muscle damage.
