Abstract

A maximal apnoea provides significant challenges to one's physiological systems, including significantly altered arterial blood gases, and requires a highly integrative response from multiple systems, that is, changes in blood pressure, maintenance of cerebral blood flow, etc. Previous work and reviews have focused on the cardiovascular responses to a maximal apnoea, but very little work has focused upon the responses of the respiratory muscles and respiratory mechanics. This is important because of the changes to arterial blood gases leading to an increased drive to breath and the appearance of involuntary respiratory muscle contractions. This review outlines what is known about how the respiratory system responds to a maximal apnoea. We put forth the hypothesis that the respiratory muscles may become fatigued following a maximal apnoea and that the respiratory muscles of elite divers may be more fatigue-resistant, which could be an important feature of these individuals which allows them to be successful in this sport. Finally, we provide direction for future work to explore the long-term health of apnoea diving.

呼吸系统对最大程度呼吸暂停的反应。

最大程度的呼吸暂停对人的生理系统提出了重大挑战，包括动脉血气的显著变化，需要多个系统做出高度综合的反应，即血压变化、脑血流的维持等。以往的研究和综述主要关注最大程度呼吸暂停时心血管系统的反应，但很少有研究关注呼吸肌和呼吸力学的反应。这一点非常重要，因为动脉血气的变化会导致呼吸动力增加，并出现呼吸肌不自主收缩。本综述概述了呼吸系统如何对最大程度的呼吸暂停做出反应。我们提出的假设是，最大程度呼吸暂停后，呼吸肌可能会出现疲劳，而精英潜水员的呼吸肌可能更耐受疲劳，这可能是他们能够在这项运动中取得成功的一个重要特征。最后，我们为今后探索呼吸暂停潜水的长期健康状况提供了工作方向。

期刊介绍： Experimental Physiology publishes research papers that report novel insights into homeostatic and adaptive responses in health, as well as those that further our understanding of pathophysiological mechanisms in disease. We encourage papers that embrace the journal’s orientation of translation and integration, including studies of the adaptive responses to exercise, acute and chronic environmental stressors, growth and aging, and diseases where integrative homeostatic mechanisms play a key role in the response to and evolution of the disease process. Examples of such diseases include hypertension, heart failure, hypoxic lung disease, endocrine and neurological disorders. We are also keen to publish research that has a translational aspect or clinical application. Comparative physiology work that can be applied to aid the understanding human physiology is also encouraged. Manuscripts that report the use of bioinformatic, genomic, molecular, proteomic and cellular techniques to provide novel insights into integrative physiological and pathophysiological mechanisms are welcomed.
