The purpose of this study was to analyze the angle of each joint for a tennis stroke using a soft and hard tennis ball for comparison. The subject were nine experienced players with five using a soft ball and four using bard tennis ball. The method of conducting the experiment was measureing the angle variance of the wrist joint, the elbow joint, and the shoulder joint with P & G goniometer. The result were as following : 1. During the forehadn stroke using the soft ball, a positive flexion movement angle of the wrist, elbow, and shoulder were noticed. Especially at the wrist joint a sudden flexion movement using the returning movement of the wrist was observed. 2. During the forehand stroke using the hard tennis ball, when hitting of males, the flexion movement was notice the wrist joint, and the elbow and shoulder joint were fairly stiff. When hitting of females, each joint was fairly stiff. 3. A difference between the usage of flexion and extension was noticed in the wrist during the backhand stroke of the soft ball. The ulner flexion movement of the wrist joint, extension of the elbow joint, and horizontal extension and abduction of the shoulder joint were readily noticed. 4. During the backhand stroke using a hard ball tennis, it was noticed in the single backhand that the wrist joint was fairly stiff, but the elbow joint was extended, and the shoulder joint was horizontal extended and abducted, being very similiar to the stroke of the soft ball. During the doublehand stroke, various kinds of wrist joint were noticed among the different tennis player. Also in the elbow joint, a flexing movement occured and the angle variance of the shoulder joint were not noticed.
