One of the proposed mechanisms to explain the positive impact of postactivation 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
A. increasing the calcium release from the sarcoplasmic reticulum.
B. increasing the muscle's sensitivity to calcium.
C. promoting increased ATP availability in the muscle.
