• The effects of "Force relaxation" level on force control

Abstract

type:Article

This study investigated the effects of "Force relaxation" level on the control of force level in isometric leg contraction tasks. Subjects were instructed to increase force from 40%MVC to 60%MVC (40-60task) and decrease force from 60%MVC to 40%MVC (60-40task). These tasks were performed in two conditions; adjusting the target force after relaxing preferable amount of force (Prefer condition), adjusting the target force after relaxing completely (Cancel condition). As a result, for the prefer condition, as the force relaxation level of 40-60task was smaller, the absolute error was greater and the velocity of the force control was greater. For the cancel condition, there was the zero-velocity time of force control for about 200ms. Our results suggest that force produced can be controlled accurately by relaxing larger amount of force, and quickly by relaxing small amount of force. Moreover, silent period that was the duration of zero-velocity appeared when the relaxing the force completely.
