Abstract:The purpose of this study was to compare VO2max, HLa and ventilatory threshold (VT) 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.Ten unacclimated men performed an incremental test to exhaustion on a treadmill under a thermoneutral condition without taking a sauna (N25℃) and during the same workload and under same thermoneutral condition after a sauna(D25℃).VO2max,VT and exercise time were increased under D25℃ than those under N25℃, but HR and HLa were decreased under D25℃ than those under N25℃. These findings demonstrate that function of sauna take on “stress protective function” on the organism.
