Abstract

This study investigated if knee joint moments are related to the foot strike angle in preplanned and unplanned handball-specific sidestep cuts performed by n = 51 female handball players. Canonical correlation analysis (CCA) with the foot strike angle as predictor variable was performed on the knee joint moment vector field (M_xyz). Subsequently, post-hoc tests using CCA for moment couples and linear regression for individual moment components were performed. In both conditions, the foot strike angle was related to M_xyz. However, the relationship remains partially unexplained when the three-dimensionality of the moment vector remains unaccounted for, especially in the unplanned cut. Given the time periods in which correlations exist, the foot strike angle shows potential to reduce multi-plane knee loading associated with ACL injury.
