Abstract

Hockey goalies all over the world have adopted the butterfly style of goaltending due to the fast pace of the game. However, the style of play has brought the potential for injuries to goalies. In this study, a motion capture system was used to analyze the butterfly motion performed by a human subject to quantify the kinematics and kinetics associated with the motion. Further analysis was done with the motion capture data to obtain the joint angles of the hip and the knee joints and the forces in the joints associated with the butterfly motions. Through the experiments, the kinematics and joint angles were obtained. With the data obtained, the kinetics, joint reaction forces and moments associated with the butterfly motions were calculated using inverse dynamics modeling. Results from the thesis showed abnormally large joint reaction forces and moments during butterfly motions, in comparison to normal walking motions, and could increase the potential for knee injuries.
