THE EFFECT OF CORRECTIVE EXERCISES ON Q ANGLE AND JUMP-LANDING MECHANICS

The Effect of Corrective Exercises on Q Angle, Balance, and Jump-Landing Mechanics in Female Volleyball Players
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.

Detaljert beskrivelse
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.

Våpen og intervensjoner
Deltakergruppe / Arm |
Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Experimental Group
Young female volleyball players (n=12) who participated in an 8-week structured corrective exercise program during the in-season period, in addition to their standard volleyball training
|
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.

Ingen inngripen: Control Group
Young female volleyball players (n=11) who continued their standard volleyball training during the 8-week study period without participating in any corrective exercise protocol.
