The purpose of this study was to investigate sex differences in single-leg squat kinematics and single-leg landing kinetics between freshman and sophomore athletes. Single-leg squat results revealed women had greater peak knee lateral rotation displacement, but no difference in total angular distances. Freshman and sophomore women were similar for peak angles and angular distances. Multivariate analysis of peak net joint moments normalized to body mass identified differences between men and women with separating variables being hip extension, hip medial rotation and knee lateral rotation moments. All three variables were greater in men. Subgroups were separated by hip medial rotation, with freshmen men being greater than freshman and sophomore women. There were no sex differences for moments normalized to momentum at ground contact. The separating variable between subgroups was ankle extension with freshman women being greater than both freshman men and sophomore women.
