One of the proposed mechanisms to explain the positive impact of post activation potential on muscle performance is that low intensity muscle contractions results in phosphorylation of myosin light chains (i. e., proteins located at the base of the myosin cross-bridge). this increased phosphorylation can increase muscle force production by
