Abstract

Abstract : This review discusses evidence suggesting that group III/IV muscle afferents affect locomotor performance by influencing neuromuscular fatigue. These neurons regulate the hemodynamic and ventilatory response to exercise and, thus, assure appropriate locomotor muscle O2 delivery, which optimizes peripheral fatigue development and facilitates endurance performance. In terms of central fatigue, group III/IV muscle afferents inhibit motoneuronal output and thereby limit exercise performance. Abstract : Group III/IV muscle afferents influence whole-body endurance capacity by determining the cardiovascular, ventilatory, and neuromuscular fatigue response to exercise.
