简要总结
This randomized controlled trial aims to evaluate the acute effects of activator-assisted talocrural joint manipulation on joint range of motion, dynamic balance, vertical and horizontal jump performance, and weight transfer parameters in elite male volleyball players aged 18-25. The study compares a manipulation group with a sham control group and assesses performance metrics before and after the intervention.
