In order to investigate the effect of myofascial release technique on sportive performance, balance and injury risk in runners, 49 athletes will include in the study. The myofascial application group (n=26)will receive 12 sessions of 6-weekly lower extremity posterior muscle therapy. The control group (n=23) will continue the routine exercise program.

Running is a sport that involves repetitive movement and is particularly vulnerable to injury in the lower extremities. Myofascial release, on the other hand, is a manual method that is effective in increasing blood and oxygen permeability between tissues, renewing the tissue, protecting it from injury and increasing performance. The aim of our study is to investigate the effect of Myofascial application on sportive performance balance and injury risk in runners. The study will carry out on runners with a 3-month running history. Myofascial application group (n=26) and control group (n=23) will divide into two groups as randomized controlled. My Jump 2 App, Y balance test and Functional Movement Analysis (FMS) will use as assessment methods. The myofascial application group will receive 12 sessions of 6 weeks of therapy for the lower extremity posterior group muscles. The control group will continue the routine exercise program.
