Document Summary
Knes 373 lecture 10 anaerobic metabolism & glycolysis. Study: bogdanis et al (1996) pcr use in repeated sprints (cont"d: ph stays quite low, even during the recovery period the numbers are not what is important the principles are what matter! Atp: creatine acts like a middle man, this is somewhat speculative but there is some evidence of this, phosphocreatine may play a important role as a shuttle. It is probably not one pcr travelling, but rather a bunch that pass the on the high energy phosphate (bump from one to the next) to cover the distance. Creatine: we make most of the creatine we need. How does creatine work: stored in skeletal muscle mainly as pcr (66%). Important for high intensity, short duration work, and/or repeated all-out efforts (exactly like the bogdanis study protocol) In theory, increasing the pcr reservoir can extend performance: may work better for vegetarians and those with low muscle cr.
