How Are VO2 Max Sessions Supposed to Feel?

No comments (cuz now I have a lot of new reading to do!), just gonna put up some more weeds…

  • Oxygen delivery lags behind the oxygen consumption and this creates an oxygen debt…oxygen debt does not cause a drop in the oxygen saturation of our blood (hypoxia), but rather forces our body to produce energy anaerobically (literally without oxygen). The imbalance caused by the oxygen debt and the anaerobic energy production can actually last for protracted time and results in excessive glycogen consumption causing problems, even on longer races such as marathons if you go out too fast. Improved fitness from training will reduce the time it takes for the body to ramp up O2 delivery.

  • Performance of prior moderate exercise resulted in faster VO2 pulmonary kinetics and also improved exercise time at 100% of VO2max. Prior heavy exercise, although effective in accelerating VO2 kinetics in a subsequent exhaustive exercise, it resulted in a shorter exercise time at VO2max compared to no prior exercise and prior moderate exercise. These results may have important implications for the preparation of athletes in training and competition suggesting the use of an optimal warm-up exercise intensity (and duration) with optimal recovery combination to improve performance.
