The two major contractile proteins found in skeletal muscle are

In short-term performances (10-180 seconds) which of the following factors is the primary cause of muscle fatigue?

Carbohydrate supplementation during exercise is most important in performances lasting

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

A high H+ concentration can contribute to fatigue by _________

In aerobic performances lasting 3 to 20 minutes, which of the following factors do not contribute to performance?

Denervation caused by motor unit aging results in_________

Which of the following metabolites have been shown to cause muscle fatigue?

The force-velocity curve describes the relationship between speed of muscle shortening (i.e., velocity of movement) and muscle force production. Which of the following statements are true about the influence of muscle fiber type on the force-velocity curve?

Which of the following statements about muscle fatigue are true?
