Abstract/OtherAbstract:
Subjects performed supination and pronation of the forearm against an inertial load with maximal voluntary effort, from either rest or when arresting the opposite motion of the load (a wind-up). The angular velocities produced at the mid-range of forearm movement were significantly greater with wind-up than without. The angle from which the movement began was significantly increased by wind-up. Isometric contractions produced torques which varied a great deal through the range of motion. While it was not possible to identify the physiology effects of wind-up, consideration was given to techniques which would achieve this aim. Wind-up was discussed in the context of skilled activity where sustained maximal contractions are unlikely throughout the activity.
