Effect of Blood Flow Restriction on Football-Related Performance Parameters

Improvement of Football-Related Performance Parameters: Application of Blood Flow Restrictive Exercise

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	Other: Blood Flow Restriction; Blood flow restriction with low load (30-50% 1RM) for 2 sessions in a week for 6 weeks during classical training will be applied.
Experimental: Classical Training Alone	Other: Classical Training Alone; Classical training same as Group 1with moderate to high load (70-90% 1RM) for 2 sessions in a week for 6 weeks will be applied without blood restriction.

What is the study measuring?

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

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
