摘要

Background

This study investigates how stance width and foot placement angles influence knee joint loading during partial squats, aiming to optimize exercise performance while reducing injury risks.

Methods

Eight healthy female college students performed partial squats with varying stance widths (1x and 1.5x shoulder width) and foot placement angles (0°, -20°, and + 20°). Kinematic and kinetic data were collected using a 12-camera motion capture system and force platforms. Statistical analysis was conducted using SPSS, including correlation and multiple linear regression analyses to examine the effects of stance width and foot placement angle on knee joint moments.

Results

Stance width significantly affected knee adduction, abduction, and external rotation moments. Increased stance width reduced knee adduction moments, suggesting benefits for alleviating medial compartment stress in knee osteoarthritis. Foot placement angles primarily influenced knee extension, internal rotation, and external rotation moments, with certain angles enhancing knee extension moments, beneficial for quadriceps strength.

Conclusions

Adjusting stance width and foot placement angles in partial squats is important for injury prevention and rehabilitation. These findings offer practical recommendations for optimizing squat performance in both clinical and athletic context. Future studies should consider exploring a wider range of stance widths and foot angles, as well as diverse populations, including different age groups, sexes, and individuals with specific knee conditions.
