Summary

This study aims to examine the acute effects of an elastic band rewarm-up on vertical jump performance in highly trained female volleyball players. A randomized crossover design will be used, with participants completing three sessions. Session 1 will serve as a familiarization with the testing and the rewarm-up protocol. In Sessions 2 and 3, participants will be divided into two groups. Group 1 will perform a standard warm-up followed by 5 minutes of rest, then an elastic band rewarm-up, while Group 2 will perform the warm-up followed by 5 minutes of rest only. In the subsequent session, the protocols will be crossed over so that each participant completes both conditions. Vertical jump performance will be assessed using the Chronojump system, evaluating both countermovement jumps (CMJ) and Abalakov jumps. To mimic real-game conditions, athletes will rotate between the vertical jump evaluations and simulated match play, allowing investigation of the acute effects of an elastic band rewarm-up on explosive lower-limb performance during volleyball-specific activity.
