Abstract

These results suggest that aerobic fitness affects the energetic response to changes in power output during moderate exercise, such that the more aerobically fit a subject, the greater the increase in oxygen cost (.VO(2)) (reduced efficiency) as work rate increases. Further, Delta.VO(2)/DeltaWR reflects the inverse of DeltaEff for moderate-intensity exercise in healthy fed subjects.
