Abstract
This paper described how the volume of respiration and the contribution between chest and abdomen were changed by clothing pressure of 3 types of jeans in standing and sitting postures. The results were as follows;
(1) In the sitting posture, jeans with a little ease gave abdomen and sides of the body high clothing pressure. Clothing pressure on sides of the body was higher than that on abdomen in all 3 types of jeans.
(2) In the analysis of clothing pressure, clothing pressure was effected by 3 factors; the types of jeans, the measurement postures and the physical characteristics of the subjects. On abdomen, the effect of measurement postures was greatest and on sides of the body, the effect of types of jeans was greatest.
(3) The volume of respiration decreased and the chest contribution increased, as clothing pressure on abdomen became higher.
