RAVEN, P. B. An overview of the problem: exercise training and orthostatic intolerance. Med. Sci. Sports Exerc., Vol. 25, No. 6, pp. 702–704, 1993. The questions, whether endurance exercise training (a) induces orthostatic intolerance and (b) alters blood pressure regulation during orthostasis, have been debated since the early 1970s. This symposium presents data that both support and discount the concepts. In addition, data were presented that document invasive and noninvasive techniques of measurement used during investigations of baroreflex and hemodynamic mechanisms of blood pressure regulation during lower body negative pressure (LBNP), a laboratory technique that simulates orthostasis. These techniques and the results obtained enabled the formulation of a hypothetical mechanism of explanation of the “pro and con” of the debated questions.
