Journal ArticleDOI
Inspiratory muscle training improves rowing performance
Stefanos Volianitis,Alison K. McConnell,Yiannis Koutedakis,Lars R. McNaughton,Karriane Backx,David A. Jones +5 more
TL;DR: IMT improves rowing performance on the 6-min all-out effort and the 5000-m trial and improves the resistance of the training group to inspiratory muscle fatigue after the 7-minute all- out effort.
Journal ArticleDOI
Brain and central haemodynamics and oxygenation during maximal exercise in humans
José González-Alonso,Mads K. Dalsgaard,Takuya Osada,Stefanos Volianitis,Ellen A. Dawson,Chie C. Yoshiga,Niels H. Secher +6 more
TL;DR: Reduction in stroke volume underlies the fall in systemic O2 delivery and uptake before exhaustion, and fatigue during maximal exercise, with or without heat stress, in healthy humans is associated with an enhanced rather than impaired brain uptake of O2 and substrates.
Journal ArticleDOI
Effects of hyperthermia on cerebral blood flow and metabolism during prolonged exercise in humans
TL;DR: The hyperthermia-induced reduction in exercise cerebral blood flow seems to relate to a concomitant 18% lowering of arterial carbon dioxide tension, whereas the higher cerebral metabolic rate of oxygen may be ascribed to a Q(10) (temperature) effect and/or the level of cerebral neuronal activity associated with increased exertion.
Journal ArticleDOI
Bicarbonate attenuates arterial desaturation during maximal exercise in humans
Henning B. Nielsen,Per P. Bredmose,M. Strømstad,Stefanos Volianitis,Bjørn Quistorff,Niels H. Secher +5 more
TL;DR: The enlarged blood-buffering capacity after infusion of Bic attenuated acidosis and in turn arterial desaturation during maximal exercise was increased and the exercise-induced increase in the difference between the end-tidal O2 pressure and arterial PO2 was similar in the two trials.
Journal ArticleDOI
Carotid baroreflex responsiveness to head-up tilt-induced central hypovolaemia: effect of aerobic fitness
Shigehiko Ogoh,Stefanos Volianitis,Peter Nissen,D. Walter Wray,Niels H. Secher,Peter B. Raven +5 more
TL;DR: The data demonstrate that the increase in the CBR responsiveness during a tilt‐induced progressive unloading of the cardiopulmonary baroreceptors was attenuated in endurance‐trained subjects, providing an explanation for the predisposition to orthostatic hypotension and intolerance in well‐trained athletes.
