Abstract

The objective of this research was to evaluate how box jump training affects lower-limb explosive strength in volleyball players. A pre-experimental approach using a one-group pretest–posttest framework was conducted on ten male athletes from BVC Ambon. Vertical jump performance served as the primary measurement instrument. Statistical testing via a t-test () revealed a significant performance gain post-intervention, with average scores rising from 55.5 to 65—representing a 17.12% improvement. Because the observed t-value () surpassed the critical threshold (), the study concludes that box jump training substantially improves lower-limb muscular power in volleyball athletes.
