Document Summary

Eqn 3050 - lecture 3 - january 16, 2018. Atpase atp changes shape of protein head and in uences its binding af nity to actin) Slow oxidative motor units so nerves also have slow oxidative capacity. High myosin atpase activity myosin has high af nity for atp. High aerobic capacity can utilize oxygen to generate atp = high endurance, posture maintenance. Low anaerobic (glycolytic) capacity it"s the glycolytic pathways that generate the most force so not very strong contractions. 20-30 muscle bres/nerve = small motor unit; precise but less powerful contractions (ie eyes) More powerful than type i but less resistant to fatigue. Will get horse over jump, propel them out of the starting gate. 2a = moderate aerobic capacity ; contract 4x faster than type i ; fast oxidative-glycolytic (fatigue resistant) motor units nerve will be a wider diameter, 2x = low aerobic capacity contract 10x faster than type i generate a ton of force but fatigue quickly.
