Document Summary

The autonomic nervous system and vasoconstriction in skeletal muscles. There is evidence of blood flow reduction per unit of. Think of the x axis as an analogy of workload (co. Single leg vs both leg exercise paradigms and measuring active muscle with recruitment of more muscle increasing = workload increasing) blood flow faster rate) compared to two leg paradigm blood flow during exercise, even well before maximal exercise. One leg exercise has a steeper slope (bf increases at a. Something must contribute to this re-distribution of: more data for calculating co: evidence for limited vasodilation around 50% of maximal effort (quads) exercise despite need for more blood. The ans & vasoconstriction in skeletal muscle: basics of the ans outlining the pns and sns distribution and functions. Pns: rest and digest, slows down hr, long preganglionic. Sns: fight or flight, speeds up hr, short preganglionic, long neurons & short postganglionic postganglionic.
