Effects of Upper Extremity Flywheel Exercises on Skills, Muscle Oxygenation, and Fatigue in Adolescent Basketball

This study will investigate the effects of flywheel exercises targeting the upper extremities on athletic performance, muscle oxygenation, physical fatigue, and muscle strength in adolescent basketball players. A total of 36 healthy male adolescent basketball players aged 10-18 years will be included in the study and divided into two groups using stratified randomization: a flywheel exercise group (n=18) and a traditional strength training group (n=18). Athletic skills will be assessed using the Johnson Basketball Skill Tests (passing test, dribbling test, shooting test), the Basketball Shooting Accuracy Test, and the Functional Shooting Performance Index (FAPI). Upper extremity muscle oxygenation will be measured using near-infrared spectroscopy (NIRS) with a Moxy muscle oxygen meter. Physical fatigue level will be determined using the Modified Borg Scale. Upper extremity muscle strength will be assessed using a Kinvent hand dynamometer and the Seated Single Arm Ball Throw Test. The flywheel group will undergo eccentric weight flywheel exercises three times a week for eight weeks. The traditional strength training group will follow a strength training program using dumbbells for the same duration and frequency. All assessments will be conducted before and after the training program.
