Abstract

The purpose of this study was to investigate the functional role of foot effectiveness when humans execute running turn maneuvers. Foot rotation angle at the starting turn and body angle at the vertical axis were analyzed through three-dimensional image analysis and ground reaction force analysis. Then, we created a simple equation: foot effectiveness = total foot rotation angle/total body rotation angle at the vertical axis. This equation made it possible to explain the dynamics of angular running turns. We analyzed data from running turns(0, 30, and 60) at average initial running velocities of 4.5, as well as rotations around the vertical axis during the running turns. As a result, the stance time, foot placement, and left and right force increased.

본 연구의 목적은 런닝 턴 동작시 많은 정확한 턴을 위한 방법으로 발의 움직임을 역학적으로 분석하기 위함이다. 런닝 턴 동작에 대한 많은 역학적인 요인들 중 정확한 턴을 위해서는 감속이 발생되고 이런 감속은 진행하고자 하는 방향으로 턴을 할 수 있게 해준다. 턴이 시작되는 시점인 발의 회전각과 이로 발생되는 몸통의 각을 3차원 영상분석과 지면반력 분석을 하였다. 따라서, 여러 매개변수들 중 수직축(z축)에서 발의 총 회전각($\theta_f$)/몸통 총 회전각($\theta_d$)= 발의 효과($\varepsilon$)로 단순화 시켜 간단한 방정식을 만들어서 설명했으며, 자료 산출을 위해 평균 속력 4.5m/s에서 진행 방향 $0^{\circ}$, $30^{\circ}$, $60^{\circ}$ 턴에 대한 분석을 통해 턴의 각이 커지면 커질수록 입각기 시간, 발 변위, 좌 우힘이 증가했음을 알 수 있었다.
