This article is based on a lecture presented in the Symposium on Ventilatory Control During Exercise at the 24th Annual Meeting of the American College of Sports Medicine, May 25-28, 1977, Chicago, Illinois.
DEMPSEY, JEROME A., DALE A. PELLIGRINO, D. AGGARWAL, and E.B. OLSON, JR. The brain's role in exercise hyperpnea. Med. Sci. Sports. Vol. 11, No. 2, pp. 213-220, 1979. Three aspects concerning the role of the central nervous system in the control of exercise hyperpnea are reviewed. First, the integration of sensory input stresses the concept of multiple sites of integration—with the end result that both adequate gas exchange and near-optimal mechanical response of the lung and chest wall are achieved during exercise. Secondly, the potential role of the “central” [H +] chemoreceptor is discussed—in terms of the mechanisms available for the protection of brain ECF [H+] and the stimulus-response characteristics of this important chemical sensor and a critical analysis of how it may be evaluated. Finally, the question of forebrain influences on exercise hyperpnea and the “sensation” of ventilatory effect is discussed, with particular emphasis on the multi-purpose regulation of breathing in athletic endeavors.
