Abstract

We investigated the 3D biomechanical differences during landing between those who have proximal (PRO) only (frontal pelvis drop down) and combined (COM) proximal and distal (frontal pelvis drop down and medial knee displacement to 2^nd toe) deviations during the lateral step down (LSD) test. Sixty-one recreational male athletes were assessed and those who met the criteria for the groups were tested in a 3D biomechanical laboratory (bilateral drop jump, unilateral forward and drop jump). We found higher hip abduction in the COM group during bilateral drop landings. The COM group also showed lower peak ground reaction force, higher impact absorption rate and higher knee frontal angular velocity during unilateral landings. Participants with LSD proximal and combined deviations differ on key kinetics during unilateral drop landings and hip kinematics during bilateral drop landings.
