EFFECTS OF FOOT PLACEMENT ON RESULTANT JOINT MOMENTS OF LOWER EXTREMITY JOINTS DURING SQUAT
Keywords: Squat stance, foot angle, gender, change in moment
AbstractThe purpose of this study was to investigate the effects of foot placement (stance width and foot angle) on normalized sagittal- and frontal-plane resultant joint moments (NRJM) of the lower extremity joints during the squat. Forty-two participants were recruited: male (n = 21) and female (n = 21). Three-dimensional motion analysis and inverse dynamics analysis were conducted. There was a significant interaction between the stance width and foot angle on the NRJM in the sagittal plane, whereas there were significant main effects of the stance width, foot angle, and gender on the NRJM in the frontal plane.
