Document Summary
Speed skating: you have to be strong, anaerobically fit, but also need to be aerobic component to race. From fatty acids we are forming acetyl-coa accumulates --> inhibits pfk. Slowing of glycolytic pathway: as acetyl-coa accumulates it feeds back pyruvate hydrogenase --> inhibits pdh. Summary: atp release from fa (palmitic acid c16h32o2, during b- oxidation 1- fadh2 and a 1-nadh+h, acetyl-coa enters cta. So for each 2 carbon compound of your fatty acids you get: remember, 2. 5 atp/ nadh+h, 1. 5atp/ fadh2, triglyceride= 3fa (lots of atp available in just one triglyceride, 3x atp= Oxygen uptake: take up, lung function is going to be part of o2 uptake. Vo2max, maxvo2 (all referring to same thing) --> maximal capacity to use oxygen. Going to be lower because you have used some: vo2max: either absolute (how much o2 did someone use at max) or relative (relative to their body weight/mass) values, example.
