Study of relevance between motion analysis and consciousness by using different insole

Abstract

In this study, we aimed to confirm objectively the change by wearing an insole with different thickness on the heel part. In addition, we aimed to examine whether human beings can understand that movement changes according to the thickness of the insole as human body sensation by reproducing the motion during the experiment after the experiment trial. The experiment participants were four healthy men in their twenties. I gave the experiment participants the full vertical jump. We set conditions that do not use insoles and three conditions using 15 mm and 30 mm insoles. The difference between the hip joint angle of the measurement trial and the reproduction trial was 14 degrees under the insole without condition, 11 degrees under the 15 mm condition, and 8 degrees under the 30 mm condition. In addition, the knee joint angle was 4 degrees under the insole without condition, 6 degrees under the 15 mm condition, and -12 degrees under the 30 mm condition. The error at 30 mm condition was the largest value.
