abstract
This study was designed to investigate the static strength exerted at the different joint angles of the hip, shoulder, elbow, and wrist, and to provide these information with clarifying the basic volleyball spiking technique. The strength was measured isometrically on the flexion and extension at several predetermined angles. Eighteen male students majoring in physical education served as subjects. The maximum flexion strength for each subject was obtained in the range from 20 to 70 degree in the hip joint, 50 to 140 degree in the shoulder, 80 to 100 degree in the elbow, and -70 to 10 degree in the wrist. The maximum extention strength was obtained in the range from 60 to 100 degree in the hip, -30 to 10 degree in the shoulder, 100 to 140 degree in the elbow, and -60 to 0 degree in the wrist. On the other hand, angles of the hip, shoulder, elbow, and wrist at the moment of impact in the international-class volleyball players were 20, 148, 155, 7 degree respectively. Although these angles were slightly deviated from those at which the maximum strength was obtained by the students, these were still acceptable in terms of generating great force in spiking. Such slight discrepancy of angles between the static maximum strength and actual spiking might be due to the fact that the point of hitting the ball was required to raise higher in the game situation.
