- Brief Summary
Blood Flow Restrictive Exercises (BFR) provide strength increase with less load than required for traditional muscle strengthening and power. As an alternative for populations that have difficulty training with high loads and speeds, low-intensity BFR training has been shown to improve muscle strength and aerobic parameters and to be safe, even in professional athletes and individuals with chronic diseases in various populations. The aim of our study is to examine the effects of BFR applied to the upper extremity on upper extremity muscle strength and performance in basketball players.
- Detailed Description
Basketball is a demanding sport that requires participants to display a high level of physical fitness and special sporting skills. Basketball requires a high level of anaerobic and aerobic conditioning and is not only a team sport, but also a sport that requires players to demonstrate their individual characteristics. In this regard, it is thought that the determination of performance components based on field tests is a more suitable method for determining the athletic levels of athletes with special needs.
BFR, which aims to restrict blood flow to the muscle during exercise, is traditionally known as 'kaatsu'. Blood flow is restricted with a pressure-controlled and monitorable exercise belt produced for BFR. In order for the method to be successful, the tourniquet method must be applied to the proximal region of the extremity, and in this way, less blood flow to the muscle can actually be achieved.
With BFR, it is recommended that the external pressure be made sufficient to restrict the arterial oxygen pressure between 40% and 80%, and it is thought that the effects of exercise increase in this hypoxic environment. In this way, it is sufficient to perform the exercises at 20% to 40% of the 1 maximum repetition, not 60-85%, which is normally required for muscle hypertrophy. An ischemic and hypoxic muscle environment during BFR; It has been hypothesized that it is produced to cause high levels of metabolic stress and mechanical tension. Both metabolic stress and mechanical tension have been described as "primary hypertrophy factors" and are theorized to activate other mechanisms for muscle growth.
Strength training performed by restricting blood flow plays an important role in muscle hypertrophy by activating the endocrine system. It has been proven that low-intensity blood flow restriction training increases the plasma concentration of growth hormone more than normal exercises. BFR involves low-intensity resistance training and is placed on the proximal portion of the lower or upper extremity muscles to be worked with a bandage or cuff that restricts blood flow, providing appropriate superficial pressure.
The aim of this study is to examine the effects of BFR applied to the upper extremity on upper extremity muscle strength and performance in basketball players.

Group Intervention Description Blood Flow Restriction Training Group Blood Flow Restriction While the basketball players continue their current basketball training; The 90-minute BFR program will be applied 3 sessions a week for 3 weeks. In the BFR program, biceps curls, triceps curls, shoulder presses, shoulder abduction exercises and sport-specific routine training will be applied. Exercises: 30% of 1 maximum repetition with resistance and 60% of arterial occlusion pressure restricted; Based on previous studies in the literature, the first set will be performed with 30 repetitions and the other three sets with 15 repetitions, a total of 4 sets and a 30-second rest between sets. There will be a 10-minute warm-up exercise before each BFR training and a 10-minute cool-down exercise at the end of the training.
- Primary Outcome Measures
Name Time Method Bench press test Change from Baseline Bench press test at 3 weeks and 6 weeks Bench Press 1RM test will be applied for upper extremity muscle strength. the athlete's 1RM weight will be determined.
Hand Grip Strength Change from Baseline Hand Grip Strength at 3 weeks and 6 weeks "Jamar (NY 10533)" brand dynamometer, one of the hydraulic measuring instruments, will be used to measure grip force.
- Secondary Outcome Measures
Name Time Method T Agility Test Change from Baseline T Agility Test at 3 weeks and 6 weeks T test will be applied to evaluate the agility of the participants.The best time of the participants will be recorded.
20 m Sprint Test Change from Baseline Bench press test at 3 weeks and 6 weeks A 20 m speed test will be applied to evaluate the speed of the participants. Running basketball players will be asked to run the 20-meter track at maximum level after starting.
Free Throw Test Change from Baseline Free Throw Test at 3 weeks and 6 weeks A shooting test will be applied to evaluate the shooting skills of the athletes. Athletes will be asked to make 2 sets of free throws with 8 repetitions after the "Start" command from the starting position behind the foul (free throw) line. Total scores will be recorded at the end of the test.
Fatigue Assessment immediately after each BFR session The modified Borg CR10 scale will be used to evaluate perceived fatigue.
