title: Role of the rapid neurogenic component and its constituents in the organization of effort hyperpnea.
abstract: 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.
