摘要：Changes in heat loss after light-short exercise and unwarmed food intake were investigated using partitional calorimetry to test the hypothesis that heat loss following these treatments is due to sweat evaporation (Esk). Four Japanese male subjects exercised at 30% of their maximum workload for 10 min and rested for 60 min. They ate 200 g almonds, drank 100 g green tea and rested for 120 min on different occasion. Rectal temperature, oxygen consumption, body weight, skin temperatures and local heat flow rates at seven sites on the skin surface were measured at 2-min intervals. The results demonstrated that the heat stored during exercise was dissipated by Esk with a 16 min delay whereas the heat produced by diet induced thermogenesis was dissipated by Esk without delay. Therefore, it was demonstrated that the supplemental heat loss pathway after both light-short exercise and unwarmed food intake was Esk.
