What does the Vo2 slow component suggest about prescribing high intensity exercise as a percentage of VO2max?
Prescribing exercise as a percentage of VO2max may lead individuals to work too hard at high intensities as they may continuously drift towards VO2max. Therefore, exercise should be prescribed as a percentage of the person's Lactate Threshold to ensure steady state workloads can be prescribed.

When given the choice, gas exchange is more effective if we increase TV than RR because it will result in greater increases in VA in the transition from rest to exercise there is a bigger increase in TV than RR VE increases roughly linearly across low and early moderate intensities, but beyond the ventilatory threshold, VE increases at a faster rate in order to blow off excess CO2 and buffer the blood As we make the transition from moderate to high intensities, we would expect a bigger increase in RR than TV
