Abstract

This study investigated the effects of changing the entry-angle of a jump landing movement on ACL injury risk factors. Eight female recreational athletes performed 21 trials of a jump landing task. The direction of the first jump varied from -90° to 90° from the anterior axis in 30-degree increments. As the entry angle increased to the left, peak knee flexion and valgus angles as well as external valgus moments remained the same. In conditions where participants jumped more to their right, knee flexion angles were smaller and knee external valgus moments were greater. It can be concluded that kinematic analyses of frontal plane motion alone may not provide sufficient information for risk assessment on the field, as it may not reflect parallel changes in kinetics. These results can be used to further understand ACL injury risk factors in asymmetric jumping conditions.
