Muscle pump and rapid vasodilation may drive initial exercise hyperemia; leaves open their relative contributions for targeted studies.
This review outlines the physiological theories and current evidence debating the relative contributions of the muscle pump versus rapid vasodilation to the immediate increase in blood flow at the onset of exercise.
Tschakovsky et al. (2004) conducted a review in Immediate exercise hyperemia. Muscle pump and rapid vasodilation was evaluated. The contribution of the muscle pump versus rapid vasodilation to immediate exercise hyperemia remains limited to indirect assessments due to the inability to measure microvenular pressure in vivo.
