ヨーガウェアの設計手法の開発

抄録

This study carried out an evaluation experiment of yoga wear on eight adult males in order to clarify required performance of yoga wear for males. The participants were asked to wear three kinds of yoga wear, selected from the products of popular yoga wear brands, and do a 15-minute yoga program three times, including yoga poses and exercises. An investigator conducted an interview survey with each participant using the evaluation grid method after he finished the programs wearing all kinds of yoga wear. At first, the investigator asked the participant to rank three kinds of yoga wear according to preference, and questioned each subject about differences between them. As a result, six evaluation items of yoga wear were acquired from their answers. After that, the investigator extracted both generic concepts and more specific concepts from the evaluation items by laddering. The evaluation structure of yoga wear was created by illustrating the relationship between all the evaluation items extracted from the interviews with the participants. In addition, fuzzy cluster analysis about the participants was carried out based on frequencies of their usages of keywords (Sense of pressure, Shape around the neck, Tactile properties, Elasticity, Presence of stitches or tags, Permiability) about the six evaluation items during interviews. The eight participants were classified into three clusters (small build, standard build, large build) according to their body type. The analysis results of data from these interviews showed that the required performance of yoga wear was mainly “not to be conscious of wearing them,” “not being painful wearing them” and “being easy to move while wearing them.” The designing of yoga wear with focus on the sense of pressure, elasticity, and shape around the neck of the clothing was required to realize this performance. Moreover, it is necessary to consider the tactile properties of clothes and the presence of stitches or tags on them for designing yoga wear, depending on the shape and needs of each individual body.
