摘要：Experiments were performed to investigate the muscle strength ratios and the maximum strengths exerted at 2 joint angles of elbow flexion and elbow extension. The subjects were 5 healthy males from 22 to 31 years old. Following results were obtained: 1.The maximum voluntary isometric muscle strength varied according to respective joint an9les. 2. The maximum strength was recorded when angles were 90° in elbow flexion and 40° to 80° in elbow extension. 3. The muscle strength ratios in both actual and calculated values were almost identical.
