Myofascial Release and Muscle Activity

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to assess the impact of SMR intervention in the hamstring muscles on the activity of the biceps and gluteus muscles.

Detailed Description
-----------------
The study will cover 40 men, players of amateur football leagues, aged 18 - 40. The test will include the measurement of sEMG of the biceps and gluteal muscles during the exercise, followed by myofascial self-release (SMR). Muscle sEMG was re-measured immediately after roller therapy.

Official Title

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Players of amateur football leagues<br>The players of amateur football leagues who will receive SelfMyofascial Release intervention | Procedure: SelfMyofascial Release<br>* Myofascial auto-release consisted of rolling the roller on a group of knee flexors for 3.5 minutes between the sciatic tumor and the knee joint in both directions, omitting the popliteal fossa. Before and after the intervention, sEMG of the biceps and gluteal muscles will be performed.<br>|
| No Intervention: Control group<br>The players of amateur football leagues who will receive no intervention | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 1. Surface electromyography (sEMG) examination before SMR | The sEMG examination of the biceps and gluteus muscles will be performed using the MyoTrace 400 recorder by Noraxon USA Inc. with a sampling frequency of 1000 Hz, using the bipolar method, in accordance with SENIAM standards.The bioelectrical activity of the muscles will be tested during the squat. | Before the SMR intervention | 
| Surface electromyography (sEMG) examination immediately after SMR | The change in bioelectrical activity of the biceps and gluteus muscles will be performed. The bioelectrical activity of the muscles will be tested during the squat. | Immediately after the SMR intervention | 
| Surface electromyography (sEMG) examination 5 minutes after SMR | The change in bioelectrical activity of the biceps and gluteus muscles will be performed. The bioelectrical activity of the muscles will be tested during the squat. | 5 minutes after the SMR intervention |
