Document Summary
As more force/work are required, we recruit larger otor units with greater numbers of contractile proteins: low forces/speeds = more recruitment of type i fibers. Isometric movements = high force x no velocity = 0 power of maximum velocity) Knes 373 lecture 9 anaerobic metabolism. Creatine kinase is used to convert between pcr + adp & cr. Knes 373 lecture 10 anaerobic metabolism. Monday february 4, 2019: atp is used in contractile proteins, resulting in. It is made in the liver, kidney and pancreas from amino acids glycine, arginine and methionine. Humans require 2g daily 1g made and 1g from food (more difficult for vegetarians: fast twitch fibers have more total pcr and cr content. Body has an upper limit of creatine storage 75-80 mm/kg dry muscle weight: stored in skeletal muscle as pcr (66%), remaining 33% is free cr. [atp] can only fall to ~ 30%; [pcr] can fall to almost zero.
