Effect of Myofascial Release on Muscle Mechanical Properties

Study Overview
=================
Brief Summary
-----------------
This study evaluates effect of self-myofascial release in different paces on muscle biomechanics. All participants will use foam roller in different paces once in a week with weeks apart.

Detailed Description
-----------------
Foam-roller is a widely used self-myofascial release method in sports. Although, effects of foam-roller has been shown, there is no defined speed of usage. Using foam-roller in different paces could cause different changes.
