Exercise Ventilatory Limitation: The Role of Expiratory Flow Limitation

BABB, T. G. Exercise ventilatory limitation: the role of expiratory flow limitation. Exerc. Sport Sci. Rev., Vol. 41, No. 1, pp. 11-18, 2013. Ventilatory limitation to exercise remains an important unresolved clinical issue; as a result, many individuals misinterpret the effects of expiratory flow limitation as an all-or-nothing phenomenon. Expiratory flow limitation is not all or none; approaching maximal expiratory flow can have important effects not only on ventilatory capacity but also on breathing mechanics, ventilatory control, and possibly exertional dyspnea and exercise intolerance.
