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.

Interventions

BEHAVIORAL

Structured Corrective Exercise Program

The corrective exercise program was implemented 3 times per week for 8 weeks during the in-season period. The protocol focused on optimizing lower extremity alignment, improving neuromuscular control, and correcting faulty jump-landing patterns. Key components included exercises targeting body segment alignment, specific drills to reduce the Q angle, and neuromuscular training to enhance Landing Error Scoring System (LESS) scores. All sessions were integrated into the athletes' regular volleyball training schedule to ensure proper kinetic chain integration and injury risk mitigation.
