Key result
Group III and IV muscle afferent fibers can sense peripheral vascular distension, potentially acting as a regulatory system that anticipates chemical changes to adjust ventilation during metabolic load.
This review proposes a physiological mechanism where slow conducting muscle afferents sense vascular distension to match ventilation with peripheral perfusion during exercise.

Extends afferent role in perfusion-ventilation matching during exercise; leaves open clinical validation and application.
Haouzi et al. (2004) reported a review. Sensing vascular distension by group III and IV muscle afferent fibers was evaluated. Group III and IV muscle afferent fibers can sense peripheral vascular distension, potentially acting as a regulatory system that anticipates chemical changes to adjust ventilation during metabolic load.
