Document Summary

February 13th, 2017: ventilation increases as work rate/intensity increases, breathing increases = increased co, at the end, we see a steep rise in ventilation. If you are trying to maintain your composure, it can be hard when ventilation is extremely high. In some sports, ventilation is performed within the constraints of the sport (whole body contraction) It will be diluted in the bloodstream = smaller fluctuations compared to in the muscle.
