Cardiovascular responses induced by constant-speed exercises in temperate and warm environments.

<p>Temporal profile of the exercise-induced changes in the MAP (<i>A</i> and <i>D</i>), HR (<i>B</i> and <i>E</i>), and double product (<i>C</i> and <i>F</i>) in rats that were previously subjected to the sham surgery (<i>n</i> = 8) or sinoaortic denervation (<i>n</i> = 8). The constant-speed exercises (18 m/min) were performed in temperate (25° C) and warm (35° C) environments. The values represent the means ± SEM. The times until the interruption of the effort are indicated by the horizontal bars. * <i>P</i> < 0.05 compared with the SHAM group.
