Analysis of throwing motion

Throwing motion needs sufficient physical strength of the shoulder and efficient coordination of the trunk and lower extremity movement. To prevent the occurrence of throwing injury, the biomechanical analysis of throwing motion it is absolutely necessary. In order to investigate quantitative understanding and evaluate each individual throwing motion being complex, the Graphical User Interface - based kinematic and kinetic analysis System (Nobuhara Hospital, Japan) was developed. 448 pitchers were measured their actions with various performance levels using a Motion Capture System. The resultant joint forces and moments in the wrist, elbow and shoulder were estimated using the inverse dynamics technique.
