Effect of Blood Flow Restriction on Football-Related Performance Parameters

Study Overview
=================
Brief Summary
-----------------
The blood flow restriction method can have similar or superior effects to high-intensity exercises even in a short duration, which can positively affect some performance parameters, can be applied with low-intensity load and cause hypertrophy in the muscle by providing high metabolic stress, facilitating muscle growth without significantly changing the total training dose. The aim of this study is to investigate whether adding the blood flow restriction method to the classical training program can be more effective than the classical training applied alone in the development of football-related performance parameters.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Blood Flow Restriction + Classical Training<br> | Other: Blood Flow Restriction<br>* Blood flow restriction with low load (30-50% 1RM) for 2 sessions in a week for 6 weeks during classical training will be applied.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of Muscle Strength and Endurance | Isokinetic dynamometer | 6 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of Lower Extremity Power | Vertical jump test | 6 weeks | 
| Evaluation of Aerobic Endurance | Yo-Yo Intermittent Recovery Level 1 test | 6 weeks | 
| Evaluation of Change of Direction Speed | T Test | 6 weeks | 
| Evaluation of Reactive Agility | Y-Shaped Reactive Agility Test | 6 weeks | 
| Evaluation of Dynamic Balance | Y Balance Test | 6 weeks | 
| Systemic Fatigue | Lactate analysis | 6 weeks | 
| General Perceived Fatigue | Borg scale | 6 weeks | 
| Evaluation of General Satisfaction and Perceived Performance Change | General satisfaction and the change in performance perceived by the participants will be evaluated with the 7 points Global Rating of Change Scale after the training program. According to the scale, it is expressed as -3: I am much worse, -2: I am worse, -1: I am a little worse, 0: No change, 1: I am a little better, 2: I am better, 3: I am much better. | 6th week |
