Passive muscle stretching reduces estimates of persistent inward current strength in soleus motor units Open
Prolonged (≥60 s) passive muscle stretching acutely reduces maximal force production at least partly through a suppression of efferent neural drive. The origin of this neural suppression has not been determined, however some evidence sugge…
