Runners maintain locomotor–respiratory coupling following isocapnic voluntary hyperpnea to task failure

Introduction Evidence has long suggested that mammalian ventilatory and locomotor rhythms are linked, yet determinants and implications of locomotor–respiratory coupling (LRC) continue to be investigated. Anecdotally, respiratory muscle fatigue seen at the end of heavy exercise may result in an uncoupling of movement–ventilation rhythms; however, there is no scientific evidence to substantiate this claim.
