Key result
The rate of increase in blood flow during rhythmic voluntary exercise is closely coupled to motor unit recruitment, with vasodilation beginning at the first contraction.

Supports motor unit recruitment driving exercise-onset hyperemia; hypothesis-generating for mechanism-targeted interventions in vascular disease.
What are the mechanisms regulating the rapid increase in limb blood flow at the onset of rhythmic exercise in humans?
The rapid increase in limb blood flow at exercise onset is closely coupled to motor unit recruitment and begins with the first contraction, independent of acetylcholine, nitric oxide, or prostaglandins.
Shoemaker et al. (1999) conducted a review in Rest to work transition. Rhythmic exercise vs. Rest was evaluated on Limb blood flow. The rate of increase in blood flow during rhythmic voluntary exercise is closely coupled to motor unit recruitment, with vasodilation beginning at the first contraction.
