Upper-arm flywheel exercises to improve skills, muscle oxygenation, and reduce fatigue in teen basketball players
Official title: The Effects of Upper Extremity Flywheel Exercises on Athletic Skills, Muscle Oxygenation and Physical Fatigue in Adolescent Basketball Players
Run by Istinye University · NCT07331012 · Data updated 2026-11-12
This trial will test whether upper-arm flywheel exercises, compared with traditional strength training, can improve shooting, passing, strength, muscle oxygenation, and reduce fatigue in healthy male adolescent basketball players aged 10–18.

Is this trial a fit for you?
✓Likely a good fit
Healthy male basketball players aged 10–18 who have played for at least one year, have trained regularly for the past six months, and have no injuries restricting participation are ideal candidates.
✕Probably not a fit
Players who recently had upper-extremity surgery, sustained an upper-extremity musculoskeletal injury within the last year, or have neurological, cardiovascular, respiratory, or metabolic diseases are unlikely to benefit or be eligible.

What this trial studies
In a randomized controlled design, 36 healthy male adolescent basketball players (ages 10–18) will be assigned to either an upper-extremity flywheel exercise group or a traditional resistance training group, with 18 participants per group. Both groups follow the same duration and frequency of supervised upper-body strength training while continuing their routine basketball practice. Outcomes measured before and after the program include basketball skill tests (passing, dribbling, shooting, shooting accuracy, FAPI), upper-extremity muscle oxygenation by near-infrared spectroscopy (Moxy), perceived fatigue by the Modified Borg Scale, and strength via hand dynamometer and seated single-arm ball throw. Between-group and within-group changes will be analyzed to determine if flywheel training yields different adaptations than traditional methods.
Why it matters
Potential benefit: If successful, flywheel training could help adolescent basketball players gain greater upper-body strength, improve on-court skills and shooting accuracy, enhance muscle oxygenation, and experience less physical fatigue.
How similar studies have gone: Prior research in adults has shown flywheel training can improve strength and eccentric adaptations, but evidence in adolescent athletes is limited and not yet conclusive.
