Metabolic demand dictates hyperemia in rat muscle; leaves open translation to human exercise physiology.
In a rat model, metabolic demand for O2 primarily controls contraction-induced hyperemia during low-intensity exercise (≤ 2Hz), whereas at higher intensities O2 delivery becomes insufficient.
Tonson et al. (2017) studied this question.
