Document Summary

Chapters 11, 14, 13, pg 40-45, 183-84, and 178-81. *motor unit: motor nerve and all of the fibers it innervates* Sliding filament hypothesis, cross bridge hypothesis are both concerned with muscle contractions. *isometric contraction: muscle does not move but is contracting. Doms (delayed-onset muscle soreness) happens a day or two after a workout using mainly eccentric contractions. Caused by tears in the myofibrils and different chemicals flow out of the muscle fiber cells which irritates the nerves. *transduction: energy is transformed from one form to another (chemical to mechanical in the body) *exercise capacity is determined on how much energy the cells can produce and how quickly it can be used* Muscular work requires transfer of chemical energy to mechanical energy. Chemical energy is supplied by atp (adenosine triphosphate) by splitting it into adp (adenosine diphosphate) and an inorganic phosphate (pi). This process can be reversed (add pi to adp to make atp)
