The purpose of this study was to examine hip and knee joint loading during the performance of the common reverse roundhouse or hook kick (Ura Mawash geri. Twenty eight black belt karate players performed hook kicks in two different ways, training kick and competition kick. Motion and force data were collected with a VICON motion analysis system and two Kistler force plates. 3D joint motions and joint moments about the hip and knee of both the support leg and kicking leg for all kicks were calculated in Visual3D. The maximum moments were more varied between kick types for the kicking leg but the joint angles were similar in most cases. Joint loading higher than in the literature for cutting actions were found, with cutting actions considered a risky action.
