Recently the legitimacy of VO2MAX as a practical measurement of cardio respiratory endurance have been called into question. ” The maximal oxygen uptake (VO2MAX) has been suggested to be the single most important physiological capacity in determining endurance running performance.” both as a physiological parameters for measuring performance capacity or as a variable for distance runner training.
Why? It is not closely tied with performance and fatigue.
The question for scientists and coaches is. Why place so much emphasis on a training method for endurance that does not change in well trained athletes, barely change in the moderately trained or does not correlate well with performance.
