The skin deformation during cycling on terrains for practical application of compression sportswear.

In this study, it is postulated that information based on skin layer deformation is necessary for the design of next-to-skin functional cycling suit. Especially for shoulder–chest region, shoulder–back region, waist–abdomen region and waist–hip region, which are critical factors in contact comfort sensations. The skin length deformation during three different road conditions (including uphill, downhill and normal road) and four cycling motions in various longitudinal, horizontal and curved directions were measured. The amount of skin deformation was slightly different for each of the five subjects, but the basic tendency of boundary between extension and contraction of skin surface was very much within the same region. The research results will help to improve cycling clothing in terms of function and comfort under the premise of the adaptation of human movement. [ABSTRACT FROM AUTHOR]
