Document Summary
Knes 373 lecture 15 assessment of aerobic exercise (vo2max) Overview: during this session we will consider various aspects of aerobic exercise, we will also review the key aspects of vo2max, we won"t cover all the slides as some are for discussion or additional information. We start of fifth about a fifth of our inspired air being oxygen: we also inspired nitrogen 79. 04% n2 typically in inspired air. It stays relatively similar to what we breathe in because our bodies don"t metabolize it very much somewhat loosely wraps around proteins but its very little. In theory, we breathe out roughly the same amount of nitrogen as we breathe in: the concentration of oxygen (%) remains the same wherever you are it is the pressure of the gases that change with altitude. More pressure = molecules closer together = easier to inhale more.
