철봉운동중 Adler동작의 역학적 분석

Kinematic Analysis of the Adler on the Horizontal Bar

&nbsp;&nbsp;The Adler on the horizontal bar belongs to B-difficulty motions and it has the special condition which reduces 0.4 point if not done.<BR>&nbsp;&nbsp;Therefore, this study was done in order to make the fundamental data useful for advancing the athletic ability through studying the athlete factor of Adler.<BR>&nbsp;&nbsp;For this study, four execellent athletes in this country were chosen.<BR>&nbsp;&nbsp;Now these are the result,<BR>&nbsp;&nbsp;1. In the Adler, when putting two legs between the two arms handstood the circle radius of the down motion of hip and ankle should be large so that it increases the acceleration.<BR>&nbsp;&nbsp;2. In the down swing of Adler, the speed increase of Hip J. should be kept very fast in the third and fourth stage.<BR>&nbsp;&nbsp;3. In the Adler, the speed increase of J. and Knee J. increase the turning power, and then made it easier to twist and straighten the shoulders.<BR>&nbsp;&nbsp;4. In the Adler, Shoulder J. and Hip J. showed the biggest change in the angle. And the waist reaction in the aerial space induced the increase of height of Hip J. and the turning power of Knee J.<BR>&nbsp;&nbsp;5. In the Adler, the shoulder remained down-vertical or right-horizontal correctly, and the position of up-vertical shoulders and wrists were advantageous.<BR>&nbsp;&nbsp;6. The pattern of angle change should keep horizonal. The bending position of shoulders, wrists and caused increase of power and height enhancing.
