Before revision: This is the minimum speed for which the organism's maximal oxygen uptake is reached (after a few minutes of exercise at this intensity) ; at higher paces, additional power is entirely delivered by anaerobic processes.
After revision: In a constant rate exercise, this is the maximum speed for which the organism's maximal oxygen uptake is reached (after a few minutes of exercise at this intensity) ; at higher paces, any additional increase in power is provided by anaerobic processes.
