Study on design method of sports compression tights based on strain measurement by digital image correlation

Abstract

In designing sports compression tights, to acquire accurate strain distributions of sports compression tights during exercise is important in order to control its pressure properly. In this study, the strain distribution of sports compression tights during exercise was acquired based on image correlation method. An artificial leg jig made of polymer foam was prepared. The artificial leg jig reproduced the shape of the leg of the CG model of the human body. The strain distributions of sports compression tights worn by the leg jig were measured by image correlation method. From the experiment, large strain was measured on the side surface of lower leg and the front surface of knee joint. From this result, design method of sports compression tights was evaluated.
