摘要：We has employed three methods to measure in examining the expanded and moved quantities of live skin: (1) the many-point method that is to write a square at approximately 14 plases on the skin of the whole body and pull each square upwards and sideways with the tip of a forefinger to measure how much each side of it has been expanded and moved than before ; (2) the two-point method that is to write two points every three centimeters lengthwise, totally about 4 places and press down (500g/100mm^2) with apulling machine to measure how much each three centimeter between the two points has been made longer than before ; (3) the one-point method that is to write a point at about 4 places and pull each with a pulling machine to measure the distance of the point moved. The subjects were 12 male students. (20 to 22-years-old) The chief results were as follows; (1) The expanded quantities by the many-point method at normal times ranged from 0.1 mm on palms and soles to 3.0 mm on the navel part. (2) The extension quantity by the two-point method at normal, after-exercise (within 20 minutes) and after-bath 9 within 20 minutes) conditions were compared with. The after-exercise measurement showed the largest quantity on every 4 place, 1.0 mm per 10 mm increase than at normal times. Whereas the normal and the after-bath conditions showed little difference. (3) The moved quantity by the one-point method was 31.0 mm normally, 32.7 mm after exercise and 28.8 mm after bath on the average of about 4 places.
