| Research Abstract |
When an individual performs a submaximal isometric contraction, there are two different load types either to produce a constant force against a rigid restraint (force task) or to maintain the position against a constant load (position task). In previous studies reported that the time to task failure for a submaximal contraction was twice as long in force task compared with in position task. In this study, we demonstrated that the position task causes more inhibitory effect on somatosensory cortex compared with the force task. Larger gating effect in the position task could imply that the task to maintain the position of the index finger while supporting a constant load requires more proprioceptive information from the group Ia afferents with which the enhanced gating of centripetal mechanism occurs.
