Effect of Blood Flow Restriction on Football-Related Performance Parameters
A study testing Blood Flow Restriction and Classical Training Alone in people with Vascular Occlusion and Soccer, run by Biruni University at 2 sites in Turkey (Türkiye).
Trial 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… Read more about this study

About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Blood Flow RestrictionOther
Blood flow restriction with low load (30-50% 1RM) for 2 sessions in a week for 6 weeks during classical training will be applied.
Classical Training AloneOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Blood Flow Restriction + Classical Training | Experimental | Not described Receives: Other: Blood Flow Restriction |
| Classical Training Alone | Experimental | Not described Receives: Other: Classical Training Alone |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluation of Muscle Strength and Endurance
Isokinetic dynamometer
Measured: 6 weeks
Secondary outcomes (8)
Evaluation of Lower Extremity Power
Vertical jump test
Measured: 6 weeks
Evaluation of Aerobic Endurance
Yo-Yo Intermittent Recovery Level 1 test
Measured: 6 weeks
Evaluation of Change of Direction Speed
T Test
Measured: 6 weeks
Evaluation of Reactive Agility
Y-Shaped Reactive Agility Test
Measured: 6 weeks
Evaluation of Dynamic Balance
Y Balance Test
Measured: 6 weeks
Systemic Fatigue
Lactate analysis
Measured: 6 weeks
General Perceived Fatigue
Borg scale
Measured: 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".
Measured: 6th week
