NCT05161273

Brief Summary

In this prospective study, male jump-landing athletes (volleyball and basketball) will be screened pre-season and followed for one consecutive season. Pre-season screening consists of 3D biomechanical analysis of standardized (such as drop vertical jump) and sports-specific jumps (such as stop-jump) before and after a high-intensity, intermittent exercise protocol and clinical field tests (such as force measurements).
