Animal findings on independent arteriolar control of flow and density; hypothesis-generating for human exercise hyperemia and requires translational validation.
This preclinical study demonstrates that muscle blood flow and capillary density can be controlled independently by proximal and terminal arterioles, respectively.
Honig et al. (1982) studied this question. Twitch contraction and exercise vs. Rest was evaluated on Capillary perfusion and distribution. Active capillary control in exercise is ungraded and solely responsible for eliminating metabolically significant diffusion paths, with flow and density controlled independently.
