为了最好地维持耐力活动,两个系统必须有效地协调:通风和运动。长期以来,有证据表明,这两种哺乳动物的节奏是联系在一起的,但运动呼吸耦合(LRC)的决定因素和影响仍在继续研究。解释LRC潜在机制的两个一般领域是(1)运动和呼吸的中枢和外周控制器之间的神经相互作用,以及(2)运动动力学和呼吸力学之间的机械相互作用。哺乳动物中存在LRC的其他建议解释/后果包括运动的能量消耗改善和呼吸困难的感觉减少。因此,通过呼吸或运动模式的改变对LRC的任何扰动可能对运动员和患者群体具有负面的表现影响。
Abstract To best sustain endurance activity, two systems must be effectively coordinated: ventilation and locomotion. Evidence has long suggested that these two mammalian rhythms are linked, yet determinants and implications of locomotor–respiratory coupling (LRC) continue to be investigated. Two general areas explaining the potential mechanisms underlying LRC are (1) neural interactions between central and peripheral controllers of locomotion and respiration, and (2) mechanical interactions between locomotor dynamics and respiratory mechanics. Additional suggested explanations for/consequence of the existence of LRC in mammals include an improved energetic cost of locomotion and a reduced sensation of breathlessness. As such, any perturbation to LRC, via alterations in breathing or kinematic patterns, could have negative performance implications to both athlete and patient populations.
