Study summary
Brief Summary
The purpose of this study is to investigate the effect of foot core exercises on jump performance in professional volleyball players. Participants will be randomly assigned to two groups. The first group will perform a strength training program only, while the second group will perform foot core exercises in addition to the same strength training program. Jump performance will be assessed using the Countermovement Jump (CMJ) test, and performance scores will be obtained through force-time analysis using the ForceDecks system. The findings of this study are expected to contribute to the development of training programs aimed at improving performance and reducing injury risk in professional volleyball players.
