This paper propose a new index for the characteristics of muscular outputs with cross section and volumes calculated by the three plane patterns (angular velocity-torque plane, angle-torque plane, and angle-angular velocity plane) on the three-dimensional surface. A peak torque was generally used to evaluate muscular strength and the evaluation with two-dimensional curve, such as force-velocity curve and force-power curve were utilized to evaluate the characteristics of muscular outputs as usual. However, even though muscular outputs among the subjects show similar experimental results on force-velocity curve, there are some cases where they show different characteristics on three-dimensional surface including angular data. In order to evaluate muscular characteristics, three-dimensional index including angle, velocity and torque value shows the detail property of muscular characteristics. We measured the elbow flexion for 9 subjects (different types of athletic events) with the system which generate isoviscous load. From obtained data we consisted of three-dimensional surface with angular position, angular velocity and torque data and calculated the volumes by three plane patterns. By using these indexes, we compared with the muscular outputs among different types of athletic events. As a result, these indexes showed significant differences among the athletic events.
