Study Overview
Brief Summary
This study examines the effects of an 8-week structured corrective exercise program on Q angle and jump-landing mechanics (evaluated via the Landing Error Scoring System - LESS) in competitive young female volleyball players during their in-season period. Twenty-three athletes were assigned to either an experimental group receiving corrective exercises or a control group maintaining standard training. The primary goal is to determine if targeted biomechanical corrections can improve knee alignment and movement quality to mitigate injury risks.
Detailed Description
The intervention consists of a specialized corrective exercise program focused on body segment alignment and injury risk mitigation, performed over an 8-week duration. Assessments were conducted pre- and post-intervention, including:
Static Q angle measurements.
Biomechanical analysis using the Landing Error Scoring System (LESS).
Countermovement jump (CMJ) height to evaluate explosive power.
The study analyzes whether integrating these exercises into in-season training effectively reduces the Q angle and improves jump-landing mechanics compared to a control group performing only standard volleyball training.
