 note = {Introduction : Oxygen concentration was gradually changed using the normal pressure low oxygen
room (chamber), the body moisture dynamic state and the circulation response were investigated, and
it aimed at clarifying the physiological response in an individual. Method:Candidates were 18 healthy
youth men (height 170.4 ± 5.1 cm; weight 66.0 ± 7.3 kg; age 22 ± 2 age; VO2max 47.4 ± 4.33 ml/
kg/min). ICW according [ a measurement item ] to part another multi-cycle bioelectricity impedance
spectroscopy (segmental bioelectrical impedance analysis;S-BIS), It was considered as the heart-ratevariability
analysis using an ECW, TW, upper arm blood-pressure (SBP, DBP), cardiac beats rate (HR),
percutaneous oxygen saturation (SpO2), and power lab. It was considered as the upper limbs, the
leg, right side of the body, left side of the body, the thigh, and the lower thigh, and S-BIS estimated
the amount of body moisture (intracellular fluid; ICW, extracellular fluid;ECW, the total amount of
moisture;TW). Moreover, SpO2 was measured using the pulse oximeter. Low oxygen environment was
carried out for [ every % ten steps, and one step ] 10 minutes. [ from 20.93% to 12% ] All measurement
was carried out in the state of the dorsal position.Result : In all the subjects, SpO2 decreased with the
fall of oxygen concentration, and it observed negative correlation in ICW/TW of the leg (p < 0.05).
Discussion: By this research, for measurement by a dorsal position, since a renin angiotensin aldosterone
system was not stimulated without the amount of renal blood flows falling, it is possible that change
of body moisture was not seen. However, it turned out that ICW increases along with the fall of SBP
and ECW decreases. It has been reported that ECW by BIA reflects plasma volume and intercellular
substance liquid (Steven et al.1996).},
