Immediate Effect of Dynamic Stretching With and Without Floss Band on Flexibility of Hamstrings in Futsal Players

Study Overview
=================
Brief Summary
-----------------
To compare the immediate effect of dynamic stretching with and without floss band on the hamstring flexibility in futsal players.

Detailed Description
-----------------
Futsal is a soccer-like indoor sport that has been gaining popularity worldwide.To increase the flexibility and ROM of involved muscle group a new method has been introduced named Flossing of tissue by using a floss band. This research study will be helpful to enable therapists to broaden their treatment plans or choose better treatment tools for improving hamstrings flexibility in futsal players. Thus, this study has been designed with the purpose to examine the effect of dynamic stretching with and without floss band on the flexibility of the hamstring.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: With Floss Band<br>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 | Other: Dynamic Stretching with Floss Band<br>* 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.<br>|
| Active Comparator: Without floss Band<br>Perform exercises without floss band. • Multi-directional leg swing | Other: Dynamic Stretching without Floss Band<br>* In this group, only dynamic stretching was applied 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.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Straight Leg Raise (SLR) Test | Universal goniometer was used to measure SLR angle. | Baseline and immediately after the intervention | 
| Active Knee Extension (AKE) Test | Universal goniometer was used to measure AKE angle. | Baseline and immediately after the intervention | 
| Sit and Reach Test | A ruler was used to measure Sit and Reach Test Score. | Baseline and immediately after the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Serum Creatine Kinase (CK) Levels | 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. | Baseline and after 24 hours of the intervention | 
| Serum Lactate Dehydrogenase (LDH) levels | Lactate Dehydrogenase is an enzyme found in body and it converts sugar into energy. When a tissue is damaged, the level of this enzyme in blood increases. This test is valid (r=0.98) to check the muscle damage | Baseline and after 24 hours of the intervention |
