Abstract

This study was to provide quantitative basic data on the forehand and backhand throw movements of flying disks. For this purpose, the kinematic variables were calculated using the three-dimensional motion analysis system. A comprehensive analysis of the study variables showed that it is important to throw flying disks accurately as well as far away, so in P2 and P3 it is necessary to control forward movement and concentrate on the rotation of the joints. In addition, rotational force transfer from pelvis to body is considered important for efficient rotational movement. The forehand was found to mainly utilize the movement of the upper extremity joint to perform throwing motion, while the backhand throw was found to be relatively utilized for the rotation of the torso and pelvis. Based on the quantitative data of this study, we hope that it can be used as a basic material for on-site training of Flying Discs.

본 연구는 플라잉디스크의 포핸드와 백핸드 던지기 동작에 대한 정량적 기초자료를 제공하기 위해 수행하였으며 이를 위해 3차원 동작분석 기법을 활용하여 운동학적 변인을 산출하였다. 연구 변인을 종합하여 분석한 결과 플라잉디스크는 멀리 던지는 것뿐만 아니라 정확하게 던지는 것이 중요하므로 P2와 P3에서는 전방으로의 이동을 제어하고 관절의 회전 운동에 집중해야하는 것으로 나타났다. 또한 효율적인 회전 운동을 위해 골반에서 몸통으로 회전력 전이가 중요한 것으로 판단된다. 포핸드는 상지 관절의 움직임을 주로 활용하여 던지기 동작을 수행하는 반면 백핸드 던지기는 비교적 몸통 및 골반의 회전을 주로 활용하여 던지는 것으로 나타났다. 본 연구의 정량적 자료를 바탕으로 플라잉디스크 현장 교육을 위한 기초자료로 활용될 수 있기를 기대한다.
