영문 초록

The purpose of this study was to evaluate how impact force changed according to both time and striking patterns while jogging. Subjects for this study were four university students in their early twenties. The women were normal and healthy. without any chronic injuries or foot problems. Independent variables for this study were jogging time and striking pattern. Jogging time was divided into six stages over the duration of one hour. Striking patterns were divided into two types: heel-strike, and toe-strike. Dependent variables were impact force, loading rate of impact force, number of impact peaks, interval time between first heel (or toe) strike to first passive peak This study utilized the Kistler type 9281B to measure dependent variables. Toe-strikers possessed lower impact force and fewer impact peaks than heel-strikers. In this aspect, jogging with a toe-strike pattern is more effective in reducing impact force, which can cause pain and injuries. For both groups, interval time between first heel (toe)-strike and first passive peak decreased progressively throughout the duration of the test. These results demonstrated not only a negative correlation between test time and interval time, but also alluded to the effects of fatigue as well. In the case of toe-strikers, impact force did not appear until after thirty minutes. As a result, people who possess a toe-striking jogging pattern can jog for less than thirty minutes in order to minimize the detrimental effects of impact force on the body. After thirty minutes toe-strikers can reduce their exercise intensity level in order to reduce the effects of impact force. Once the effects of fatigue are eliminated at a lower intensity level, toe-strikers can increase their intensity levels back to normal. Heel-strikers displayed impact force from the beginning of the test duration until the end. Furthermore impact force increased steadily with time. Therefore, it is especially important for heel-strikers to have adequately cushioned shoes, socks, and jogging surfaces.
