Three experiments were run with each of five young male subjects to investigate the effects of three different environments on the recovery from heat stress. Duration of all the experiments was 2 h. The first hour was spent on a bicycle ergometer working at a load of about 60W in a 40°C and about 25 % RH chamber. In the second hour, subjects were exposed while sitting to more comfortable environments. These environments included a fixed temperature equal to the preferred one determined for each subject in a preliminary test, and two varied schemes starting either 5°C above or 5°C below the preferred temperature. Changes in chamber temperature were made according to subjects' requests. Results of this study appear to indicate that variable temperatures in recovery rooms may be preferable, from a subjective comfort standpoint, to the fixed one Subjective judgements of all environments at the beginning of the recovery period were nearly the same for all conditions studied, which is in contrast to previous steady state studies. For the entire duration of the recovery period the environment with the highest average temperature was judged as the most comfortable among the schemes studied, which may lead to energy savings in recovery rooms. It was apparent that the thermoregulatory system was biased by the initial condition which influenced the thermal sensations of the subjects. Heart rate was also found to decrease more when the temperature was varied in the recovery chamber relative to its decrease in the fixed environment. This study also indicates a possible anticipatory effect of the rate of change of skin temperature on the comfort feeling and sensation. |
