The Effect of Dehydration after a Sauna and Intermittent Hypoxia Stimuli on Heat Stress Protein 70 in Human Leucocytes and Aerobic Capacity during Incremental Exercise / 中国运动医学杂志

ABSTRACT

The purpose of this study was to compare Heat Stress Protein70 (HSP70) in human leucocytes, VO2max and Blood Lactate (BLa) during incremental exercise under a thermoneutral condition without taking a sauna with those during the same workload and under same thermoneutral condition after a sauna and after intermittent hypoxia stimuli. Ten unacclimated men performed an incremental test to exhaustion on a treadmill under a thermoneutral condition without taking a sauna (N25℃, relative humidity 65%) and during the same workload and under same thermoneutral condition after a sauna (D25℃, relative humidity 65%), and after intermittent hypoxia stimuli (LN25℃, relative humidity 65%) . The results were as follows (1) HSP70 levels before incremental exercise in D25℃ were significantly higher than that in N25℃(13701.87?5367.17vs 7517.57?1980.01,P
