Document Summary
Put mask on, measure volume of o2 going in, esimate amount of co2 coming out. Doping would not really increase the untrained person"s vo2 max. Higher in skeletal muscle for all intensiies. Unreliably measured (faigue, out of shape, not avg. max hr) Ventricular walls thicken (hypertrophy) in response to blood low, due to o2 consumpion. You cannot increase the amount of o2 in arterial blood. 98% of o2 is bound to hemoglobin, only 1- You can decrease the amount of o2 let in venous blood. Training can double the amount of mitochondria in the muscle. An untrained person increases output at the same rate as trained person, but will hit a wall. If someone is heavier, they require more oxygen. Vo2maxpred = (work/body mass x 1. 8) + 7. 0. O2 cost of workload similar for everyone. Sv will plateau at about 40-60% of vo2max.
