This study investigated the effect of elbow and forearm rotation angle on forearm torque strength and endurance. Twenty-four male subjects participated in the study. The results revealed that supination torques were stronger overall with a mean maximum value of 16.2 Nm recorded for the forearm 75% prone. Maximum pronation torque was recorded as 13.5 Nm for a neutral forearm with the elbow flexed 45°. Endurance times were longer for supination torques with the elbow flexed 135° and 90° but reduced below the times of pronation for the elbow fully extended. Supination torque endurance times were affected more by elbow and forearm angles than were pronation torque endurance times.
