Grip strength is usally used as an indicator of muscular strenght. However, in various exercises muscular activities of forearm are very complicated and there are many muscular activities which can not be elucidated with grip strength alone. Forearm supination and pronation strength have many activities in various exercises and seem to be related to the skill of motions in upper extremities, but these muscular strengths have not been investigated. This study was designed to investigate the function of forearm supination and pronation as a step of study on forearm muscular activities. The following results were observed : 1. Angle of forearm supination in all subjects was greater than forearm pronation in both forearms, but there was not significant difference between left and right forearm. 2. Alternative motions of forearm supination and pronation per 10 sec. did not differe between left and right forearms. 3. In the maximum supination and pronation strenght in left and right forearm, forearm supination strenght was greater rather than the pronation strength. But there was not difference between left and right forearm. 4. In maximum rate of raise in forearm supination and pronation strength, it was greater in expenditure of supination strenght than in pronation strenght. 5. Expenditure of supination strength or pronation strength in the forearm was correlated with rate of raise of forearm pronation or supination strength.
