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.

Full description

Detailed Description

This study is designed to examine the effects of foot core exercises on jump performance in professional volleyball players. Participants will be divided into two groups: a control group and an intervention group. The control group will follow a standardized strength training program, while the intervention group will perform the same strength training program combined with additional foot core exercises.

Jump performance will be evaluated using the Countermovement Jump (CMJ) test. Kinetic variables derived from force-time data will be collected using the ForceDecks system. Pre- and post-intervention measurements will be compared to determine the effects of the training programs.

The results of this study are expected to provide evidence-based information for designing training programs that enhance athletic performance and help reduce injury risk in professional volleyball players.
