Increased levels of FFA during passive heat loading after a 2-week repeated heat load in Koreans

초록

The purpose of this study was to determine whether repeated heat load is closely related to circulating levels of free fatty acids (FFA) during repeated passive heat loading (PHL), defined as immersion of the lower body up to an umbilical level in hot water, 42 +/- 0.5 degrees C (three times/week, 30 min/day) for 2 weeks. There were significant correlations between mean body temperature and FFA before and after repeated heat load (p<0.001, respectively), and the level of FFA was significantly higher after repeated heat load during PHL (p<0.01). The threshold of mean body temperature for lipolysis was lowered by repeated heat load and enhanced lipolysis during PHL. However, caution is needed for diabetic individuals.
