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.

当个体进行次最大等长收缩时，有两种不同的负荷类型，一种是在刚性约束下产生恒定力(力任务)，另一种是在恒定负荷下保持位置(位置任务)。在以前的研究中，力量任务的任务失败时间是姿势任务的两倍。在本研究中，我们证明了与力量任务相比，位置任务对躯体感觉皮层的抑制作用更强。位置任务中较大的门控效应可能意味着，在支持恒定负荷的同时保持食指位置的任务需要来自Ia组传入的更多本体感觉信息，向心机制的增强门控发生在Ia组传入神经元上。
