The gas that reaches the gas-exchange zone of the lung is termed

A potential mechanism that could contribute to central fatigue includes_________

The formation of cross-bridges that initiate the contractile process in skeletal muscle is triggered by

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
