Running performance during constant-speed exercises in temperate and warm environments.

<p>Effects of the sinoaortic denervation (SAD; n = 8) or sham surgery (SHAM; n = 8) on running time until the voluntary interruption of the effort (A and B) during constant-velocity exercises (18 m/min). The exercises were performed in temperate (25° C) and warm (35° C) environments. The values represent the means ± SEM. * <i>P</i> < 0.01 compared with the SHAM group. Panels C and D show the curves of the maximal exercise duration tolerated by the SAD or SHAM rats subjected to constant-speed exercises at the two ambient temperatures. The data are expressed as proportions of rats that were still running at given time points.
