Abstract

This study developed functional leggings to guide correct posture for women not trained in the squat exercise technique. Through in-depth interviews, we developed four types of functional leggings that prevent unskilled women from rotating their legs inward or outward, both improper squat forms. These functional leggings include two types of design variables: MD(medial direction design), which turns the lower extremities inward; LD(lateral direction design), which turns the lower extremities outward; and two types of variables according to material. The angles of each part of leggings during the squat movement were measured, and subjective sensations by women were evaluated, including control leggings CD(control design) without rotation function. There was no difference in the adduction and abduction angles depending on the type of functional leggings. However, at the rotation angles of the hip joint (p=0.005), femur (p=0.016), and tibia (p=0.000), the MD leggings rotated inward regardless of the material. Further, the LD leggings rotated outward regardless of the material. The developed functional leggings had an excellent subjective sense of ease of movement, pressure, and preference, thus the developed functional leggings were appropriate while guiding squat posture.
