A Cineradiographic, Kinesiological and Electromyographic Study of Ankle Movement During the Use of Shoes for Walking and Running
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.5 Vol.5】
Using electromyography, electrogoniometry, cineradiograph, and foot-contact kinetic measurements (contact forces, barogram, and center of pressure pattern), we investigated walking and running to gather basic data on shoes. We obtained the following results.
1. During contact with the ground, forces were concentrated mainly (a) at the heel, especially on the outside border, and (b) along the fore-foot in the region of the metatarsal heads. For this reason the shoe needs to adequately support the calcaneus and the metatarsal heads.
2. When the foot pushes off to leave the ground, the midfoot, especially that part around the ball of the foot, should not be restricted by the shoe so as to add to the load of the calf muscles.
3. The upper portion of the toe compartment should be constructed so as not to restrict hyperextension of the great toe before the heel contacts the ground.
4. Electromyography, polyaxial electrogoniometry, cineradiography, and simultaneous determina-tion of (a) contact forces, (b) distribution of contact pressure, and (c) path of the center of pressure can all combine to give useful information that might aid in the optimal design of shoes.
