Dynamic muscle oxygen saturation discriminates boundaries between exercise intensity domains, exposes a critical metabolic rate, and predicts time to exhaustion during severe whole-body exercise.

Does dynamic muscle O2 saturation predict time to exhaustion during severe domain whole body exercise?
The matching of oxygen supply and demand is a primary determinant for sustainable exercise intensities and can predict time to exhaustion.
Dynamic muscle O 2 saturation discriminates boundaries between exercise intensity domains, exposes a critical metabolic rate as the highest rate of steady state O 2 supply and demand, describes time series depletion and repletion for work above critical power, and predicts time to exhaustion during severe domain whole body exercise. These results highlight the matching of O 2 supply and demand as a primary determinant for sustainable exercise intensities from those that are unsustainable and lead to exhaustion.
Kirby et al. (Thu,) conducted a observational in Exercise. Dynamic muscle O2 saturation measurement was evaluated on Time to exhaustion and critical metabolic rate. Dynamic muscle oxygen saturation discriminates boundaries between exercise intensity domains, exposes a critical metabolic rate, and predicts time to exhaustion during severe whole-body exercise.
