Problem:
Question 1: What physiological factors may affect ATP consumption per cross bridge cycle as well as muscle tension development?
Question 2: What will happen if the sarcoplasmic reticulum of the fiber is impaired (i.e. reduced efficiency of calcium uptake into the sarcoplasmic reticulum and/or uncoupling of sarcolemmal excitation and calcium release?
Question 3: How might drugs that mimic neurotransmitters affect the physiologic response to exercise as well as exercise performance?
Question 4: What is neuromuscular fatigue and what are the most likely factors that explain the phenomenon? Can neuromuscular fatigue be prevented or improved?
I dont need long explanation. Just few sentences of expanation.
