I was just thinking about the big increase in rate of breathing that occurs as I near max aerobic power, and I'm wondering what causes this? It can't be to bring in more oxygen, because my increase in breathing going from up to 440 watts from 400 watts is about 30% yet the power increase is only 10%. I
always fail (to increase power) because I get pain in my respiratory muscles (diffusely around rib cage, or bottom of rib cage). I no longer experience feelings of heaviness or fatigue in my legs (except after maybe 4-6 hrs) unlike last year
when I most certainly did. I get this feeling like the heavy breathing at max aerobic power is almost an overcompensation, or some kind of reaction to stress without really being tremendously useful itself. Any exercise physiologists here know why the sudden jump in respiratory exchange in going from 90% to 100% VO2 max?
