An investigation of the role of the rapid neurogenic component and its constituents in the organization of effort hyperpnea was carried out in athletes during physical loads increasing stepwise. The contribution of the condition reflex constituent in the general ventilatory response increases after the subject became acquainted with the increase in the severity of the demands, while with the use of loads in randomized order, its magnitude was approximately identical. With an increase in the metabolic cost of the work, the contribution of the rapid neurogenic component to the overall magnitude of the effort hyperpnea progressively decreases. The tendency to increase in the rapid neurogenic component in experienced athletes is the consequence of adaptive change due to the condition reflex constituent.
在运动员逐步增加体力负荷的过程中，对快速神经源性成分及其组成部分在用力性呼吸增强的组织中的作用进行了研究。在受试者熟悉了需求强度的增加后，条件反射成分在总体通气反应中的贡献增加，而当以随机顺序使用负荷时，其大小大致相同。随着工作代谢成本的增加，快速神经源性成分对用力性呼吸增强总体幅度的贡献逐渐降低。经验丰富的运动员中快速神经源性成分增加的趋势是由于条件反射成分导致的适应性变化的结果。
