Heat acclimatization and nutrient balances. On the oil tanker S.S. Esso Newcastle, metabolic balances were investigated in three medical students and three working members of the crew during three-day experiments conducted when the ship was located in Biscay, the South Atlantic, and the Persian Gulf. Information was sought on the possible changes in nutrient requirements and the significance of the losses of nutrients in sweat when the subjects became acclimatized to heat. Physiological parameters of acclimatization were measured on each subject by controlled hyperthermia using a heated test-bed. Details are also given of the procedures devised for measuring the daily intake and loss of nutrients in metabolic balance studies on working subjects.
