1. What physiological factors may affect ATP consumption per cross bridge cycle as well as muscle tension development?
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?
3. How might drugs that mimic neurotransmitters affect the physiologic response to exercise as well as exercise performance?
4. What is neuromuscular fatigue and what are the most likely factors that explain the phenomenon? Can neuromuscular fatigue be prevented or improved?
