A potential mechanism that could contribute to central fatigue includes_________

One of the proposed mechanisms to explain the positive impact of post-activation potential on muscle performance is that low-intensity muscle contractions result 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
