Skeletal muscle is known as "water storage organ", but in elderly people with reduced skeletal muscle mass, orthostatic hypotension tends to be caused by decrease in body fluid volume and muscle pump action. Bioelectrical Impedance Analysis (BIA) is adopted as a simple method to measure the body composition including the human body fluid volume, muscle mass, and body fat rate. Using BIA, we investigated time-course changes in the body fluid distribution in various body segments with posture change of the elderly subjects. The body fluid distribution was measured in 9 body segments during the 15 min supine position and 15-min standing position. The body fluid volume in the trunk was observed to decrease or increase during standing position in elderly subjects. The body fluid volumes in the arms, abdomen, and lower limbs gradually increased during standing position. It was suggested that BIA provides more information on the indices of orthostatic intolerance and heatstroke.
