Abstract : The metabolic and thermal responses to muscular exertion in a cold environment were studied in outdoor and indoor workers. The resting metabolic rate in a thermally neutral environment was significantly higher for the outdoor workers. In a situation of general body cooling without muscular exercise metabolic response was less for the outdoor workers. The metabolic rate during exercise was found to be higher in all subjects in the cold environment than in the warm environment at low levels of work, at higher workloads it was the same. There was a tendency towards lower oxygen uptake in the cold of the outdoor workers than of the indoor workers at low levels of work. At high levels it was essentially the same. The rectal temperature was not altered significantly in the cold when the work performed was light. At higher levels of work rectal temperature increased in the cold, reaching an equilibrium which was the same as when the same amount of work was performed in a thermally neutral environment. No differences in rectal temperature were found between outdoor and indoor workers. (Author)
