Document Summary

In a manner similar to that for o2, we can determine the amount of co2 expired. = (ve x feco2) - (vi x fico2 = 0. 0003 inspired) Under steady state conditions (oxygen consumption is staying the same = moderate intensity exercise below the la threshold) these values can be used to estimate the pattern of fuel use (cho and fats) 6o2 + c6h12o6 6co2 + 6h2o + energy. Requires 6 oxygen to metabolize the mole of glucose. Requires 23 oxygen to metabolize the mole of palmitate. We have to consume more oxygen to metabolize fats. Anytime the ratio is below 1 you are burning more fats. Typically around 0. 8-67% fat and 33% cho. Rer increases with exercise intensity and in non-steady state exercise may increase above 1. 0 good indicator of maximal effort. As intensity increases the expiratory exchange ratio changes with the intensity. Work load increasing so you need more atp.
