Clothing Pressure and Physiological Responses According to Boning Type of Non-stretchable Corsets

摘要

We explored the effects of the boning corsets on women's health so that the body's physiological response to the corset's pressure was measured by the "changes in heart rate, blood flow, perspiration, metabolism and their subjective pressure sensation when exercise. The corsets were reconstructed with or without boning inside the corsets with 10-20 % smaller waist girth of participants. Five women in their twenties volunteered to be our test subjects. The results vary according to the corset type and time period of exercise process. The peak corset pressure appeared almost 7 kPa with the most boning-type Corset B. Compared to the control group that did not wear a corset, the heart rate of the corset wearers decreased up to 15-20 % at most changes of Corset C, blood flow at the finger tips decreased 36 % at most changes of Corset C. And perspiration decreased up to 90 % at maximum of Corset A. The energy expenditure of corset wearers increased 14 % at most of Corset B due to higher corset pressure in sides even at the same activity level, which means that more energy is required to make the body torso move. Physiological responses were different according to corset type, that is, the most boning-type corset showed highest clothing pressure at 2 points, under armpit and near the side waist point and highest changes of energy metabolism, but showed least changes of heart rate and blood flow among the corsets. This is for it enhances blood circulation during exercise movement of body as seesaw effects of leveraging boning wires on blood vessels. Thus we can say the most boning type of corset affected the physiological responses and body comfort positively specially when body exercise, eventhough the boning inside corset enhanced clothing pressure partially.
