13. Comparação entre diferentes metodologias para detecção do limiar de anaerobiose durante exercício físico em cicloergômetro de homens saudáveis e com infarto do miocárdio.
The objectives of this study were: to determine AT of healthy (HI) and coronary disease (CD) men by ventilatory visual method (gold standard) and by means of Hinkley statistical method applied to heart rate (HR), carbon dioxide output ( CO2) and surface electromyography (sEMG) root mean square (RMS) data, and to compare both methods in each studied group; to

14. Ventilatory responses during arm and leg exercise at varying speeds and forces in untrained female humans.
1. Involvement of neural stimuli, central and/or peripheral in origin, in exercise ventilatory control was ascertained by examining the ventilatory responses to varying mechanical conditions of arm and leg cycle ergometries. Twelve untrained women underwent each of two modes of exercise at three levels of loading (0, 5 and 10 N), each at three levels of spee

15. Role of the carotid bodies in the respiratory compensation for the metabolic acidosis of exercise in humans.
1. In response to an acute exercise-induced metabolic acidosis, the fall of arterial pH is constrained by the magnitude of the compensatory hyperventilation. To determine the role of the carotid bodies in this regulatory process, subjects performed prolonged (24 min) square-wave cycle ergometry from a background of unloaded cycling at inspired oxygen fractio

16. Cardiovascular, ventilatory and catecholamine responses to maximal dynamic exercise in partially curarized man.
1. In ten young men the ventilatory, cardiovascular, catecholamine and metabolic responses to maximal dynamic leg exercise on a stationary bicycle were followed during partial neuromuscular blockade with tubocurarine. Maximal exercise was performed when the drug effect was at its maximum as well as during the subsequent reduction in the effect allowing a gra
