Mod, moderate exercise. Max, maximal exercise. LF, low aerobic fitness. IF, intermediate aerobic fitness. HF, high aerobic fitness. VO_2max, maximal pulmonary oxygen uptake; IVO_2max, work-rate associated to VO_2max.MRT, mean response time of oxygen uptake kinetics. ^a significantly different from LF at the same intensity. ^b significantly different from IF at the same intensity.
