평지와 경사 달리기 시 인체 운동사슬에 관한 역학적에너지 해석연구

Abstract

The purpose of this study is to investigate the effects of lower limb and trunk segments on the flat and 5° slope running of male subjects in their early 20s. The kinematic variables of the lower limb and the trunk segment were investigated and the correlation between the two types of trunk model Ⅰ and trunk model Ⅱ was investigated. The following conclusions are obtained. First, there was a statistically significant difference in the leg joints in the weight-absorbed area according to inclination. Especially, the knee joints showed high level running and the hip joints showed high level of 5°slope running. Second, there was a difference in the inter pretation of the kinetic energy of the trunk generated by the trunk model two types. In the case of trunk model I, there was a statistically significant correlation between the trunk energy and the hip joint in the weight absorbing zone and the propulsive zone in the flat running. The 5°sploe running showed a significant correlation in the body weight absorbing zone. In case of trunk model Ⅱ, there was a statistically high correlation between the upper body of the torso and the knee joint in the flat running, and there was a significant correlation in the lower body of the torso and the knee joint in 5° slope running. From the above results, it is found that the hip and the knee joint affect the running exercise according to the inclination from the kinematic analysis of the upper body of the trunk and the lower extremity. Therefore, the upper and lower parts of the trunk should be strategically considered for efficiency and effectiveness in applying exercise techniques and training in hip joint and knee joints in terms of power output and energy efficiency.
