하이컷 축구화가 발목 안정성과 운동수행능력에 미치는 영향

Abstract

The purpose of this study was to research how the existence of a collar, an ankle protection form of football shoes, affects the stability of ankles during landing motions and direction change motions during running, and the differences between them. Because the amount of impact received from the ground is different depending on the type, shape, number, and distribution of the studs of the football shoes during the landing motion, the football shoes used in the experiment were selected as similar models for each size. In order to achieve the research objectives, there are no injuries to the body such as the pelvis and waist, including the ankle joint, knee joint, and lower extremity muscles within the last 3 months, and there are no chronic injuries, and 10 college students who get involved university soccer club. These subjects wore high-cut football shoes with the design of the shoes covered their ankles, jumped after two steps, performed a motion to land naturally after heading an aerial ball, and then performed the same with regular football shoes. Ankle rotation, flexion, inversion and knee flexion angle were measured. The direction change motion is a running motion that runs from the starting line and returns to the first turn point after two 45-degree turn motions. Likewise, when wearing high-cut football shoes and wearing regular football shoes, the acceleration of the center of the body was measured. Based on each measurement, emphasis was placed on comparing when wearing high-cut football shoes and wearing regular football shoes. The kinematic variable analyzed in this study was the change angle of the ankle. Inertial sensor IMU was used to measure the variable, MR v3.8.3 was used for the analysis program, and SPSS 22.0 was used for statistical processing of the result data. As a result of this study, the difference between knee and ankle angles and body acceleration was not significant when wearing high-cut football shoes and regular football shoes, so the ankle collar of high-cut football shoes do not significantly affect ankle stability and motional performance compared to regular football shoes.
