Effects of stance width and foot placement angle on knee joint loading of partial squats in healthy female university students: a cross-sectional study.

ABSTRACT:

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. In
