PURPOSE This study tested the hypothesis that the magnitude of cardiovascular (CV) drift and decrease in maximal oxygen uptake (V[spacing dot above]O2max) would be greater at 35 degrees C than at 22 degrees C. METHODS The increase in HR and decrease in stroke volume (SV) between 15 and 45 min of cycling at 59.2 +/- 1.9% V[spacing dot above]O2max (CV drift) was measured in hot (HEAT, 35 degrees C) and cool (COOL, 22 degrees C) ambient temperatures in 10 endurance-trained men (age = 23 +/- 3 yr… CONTINUE READING
