• Description:
  Seven women worked intermittently in three randomly ordered sessions at 75% of aerobic power at three temperatures, and recovered in a cool environment after each work period. Although rectal temperature was higher in each successive work period, the ambient temperature had no effect on the cardiovascular or respiratory responses or on rectal temperature. In all conditions stroke volume decreased with time with a concomitant increase in heart rate to maintain heart output. A fall in mean blood pressure from the initial to final measurement was due entirely to a decrease in diastolic pressure. The final rectal temperature for these women was approximately equal to that previously reported for men working continuously for one hour under conditions equivalent to time- weighted average of the thermal and metabolic loads during work and recovery in this study.
