Also, the inverse dynamics analysis was applied to inspect the horizontal, vertical forces and net muscle torque of wrist, elbow and shoulder during the process of forehand groundstroke. Five college tennis players were participated as subjects in this study. The following is the basic data of the experimenters. The average age is 22.4±2.3 years old. The average height is 174.6±3.2 cm. And the average weight is 69±4.2 kg. Two Mega Speed high-speed digital cameras(250Hz) and SIMI Motion software were used to collect the data. And we applied the inverse dynamics analysis to examine the force and torque for each joint of upper limb. The result of this study was expectably coincident with the stroking pattern of the subjects. During the whole process of the stroking, the elbow and the wrist were mostly expressing straining and flexing. Finally, the inverse dynamics analysis showed that the shoulder had the greatest force to keep stability of stroking.
