摘要：

The discharge of 18 single unit spindles located in the right crural diaphragm was recorded during rhythmic diaphragmatic contractions before the onset of and during fatigue. Spindle discharge was significantly greater (P <0.05) during rhythmic exercise when the diaphragm was fatigued than spindle discharge during rhythmic exercise when the diaphragm was not fatigued. The increase in spindle discharge during diaphragmatic fatigue is inconsistent with the notion that spindles comprise the afferent arm of a fatigue-induced inhibitory reflex originating in the diaphragm.
