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.
这篇综述讨论了证据表明，III/IV 类肌肉传入神经通过影响神经肌肉疲劳来影响运动表现。这些神经元调节运动时的血液动力学和通气反应，从而确保运动肌肉的适当氧气输送，优化外周疲劳发展并促进耐力表现。就中枢疲劳而言，III/IV 类肌肉传入神经抑制运动神经元的输出，从而限制运动表现。
