METABOLIC AND THERMAL RESPONSES TO MUSCULAR EXERTION IN THE COLD
Abstract
The metabolic and thermal responses to muscular exertion in a cold environment were studied in outdoor and indoor workers. The metabolic rate in all subjects during exercise was higher in the cold environment than in the warm environment at low levels of work; at higher workloads it was the same. In the cold environment there was a tendency towards lower o xygen uptake of the outdoor workers than of the indoor workers at low levels of work; at high levels it was essentially the same. Differences in skin temperature and onset of rewarming indicate an adaptability to cold of the vasomotor control mechanism of the peripheral circulation. It is suggested that habituation to cold leads to a lower set point of the thermosensitive cells of the thermoregulatory center, so that vasodilation impulses are discharged at a lower temperature.
