국제 체조 연맹이 정하는 자유 종목에서는 채점 규정상 B난도에 해당된다. 국가 대표 선수 3명을 대상으로 경기력 향상을 위한 기초 자료를 제공하고자 철봉 몸펴 앞돌아 물구나무서기 동작에 대한 보다 정확한 과정을 모색하고 좀더 발전적이고 변형된 기술 습득을 위한 운동학적 변인을 분석하였다. 1. 제 2 구간에서는 신체중심의 수직속도를 증가시키고 Bar에 가깝게 신체를 회전시킴으로 안정된 자세 동작을 수행하는 것이 바람직한 것으로 나타났다. 2. 제 3 구간에서는 신체중심의 수평속도를 빠르게 하고 견관절, 슬관절을 굴곡시켜 회전력을 증가시키는 것이 중요한 요인으로 나타났다. 3. 제 5 구간에서는 수평위치를 회전축인 Bar로부터 회전반경의 길이를 길게 하여 회전력을 상승시키고 견관절의 굴곡을 크게하고 신체를 layout시켜 다음 Swing동작의 준비를 여유있게 하는 것이 중요한 것으로 나타났다. 이상을 종합해보면 철봉 몸펴 앞돌아 물구나무서기 연기 동작을 수행하는데 제 2 구간에서 신체중심의 수직속도를 증가시키고 제 3구간에서 회전반경을 짧게하여 회전력을 높이고 제 5 구간에서 수직상승운동을 위치에너지로 바꾸는 것이 동작을 성공적으로 연기할 수 있는 중요한 요인임을 알 수 있다.

This study has researched on the motion of ´the free hip circle forward to handstand motion on the horizontal bar´ as performed by the three national representative champion as its object for the purpose to present fundamental data for the improvement of competitiveness, in such a manner as to seek a more accurate progress and a more evolved and transformed skill to be attained, based on the kinematic factors as analysed below. 1. At phase 1, it was shown to be desirable to take a short rotation radius with enough room when shortening composite location of physical center, slowing down both in a little flexion. 2. It was also desirable at phase 2 that the vertical speed of the physical center should be increased; motion should be performed in a stable posture by shortening the front of moment, rotating the body closely to the bar when doing down rotation. 3. Phase 2 has revealed it to be an important factor to increase the rotation force by quickening both the vertical and horizontal speeds of the physical center and flexing the shoulders and knees. 4. Phase 4 indicated the rotation force should be raised and the vertical speed of vertical uprising should be used by flexing the shoulders and making the physical center close to the bar from the rotation axis. 5. It was important, as phase 5, that the composite location should shorten the length of rotation radius from the bar, which is the rotation axis so as to accelerate the rotation force and enlarge the flexion of the shoulders, lay out the body, and then prepare for the swinging motion in good allowance. To summarize the forerunning aspects, in the performance motion of the free hip circle forward to handstand motion on the horizontal bar for a more advanced, transformed, improved skill, motion, and competitive force, it was learned to be an important factor that the body-centered vertical speed should be increased at phase 1 and 2; the rotation force should be accelerated by reducing the rotation radius at phase 3; and the vertical uprising motion should be changed into the location energy at phase 5. These appeared as important factors for successful performance.
