2011 대구세계육상선수권대회 Gilde Type 포환던지기 한국선수와 결승 1, 3위 선수와의 운동학적 비교분석 = Cormparative Analysis from Perspective of Kinesiology between Korean Athletes and Gold and Bronze Medalists in Glide-Type Shot Put at Daegu World Athletic Championships in 2011

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze, in real time, the glide motion and release motion of domestic athletes and gold and bronze medalists employing the glide technique for the men`s shot put at the Daegu World Athletic Championship in 2011. In the glide motion, the Korean athletes had a relatively high body center and shot put heights and lager stretching angles for their hips and knees. In the delivery phase, which shifts to the release phase, the Korean athletes showed slower vertical body center and shot put speeds, and they changed the phase, to the release phase by using a small body angle. In the release phase, the Korean athletes showed differences in their projection speeds and vertical body center speeds. The world-famous players showed high angle speeds, which refer to the composition of the rotation force at the moment of release (body, hip, and shoulder line). In the release phase, the Korean athletes did not have fully stretched hip and knee angles, which might have negatively influenced the vertical speed, because the Korean athletes showed relatively low projection heights and projection angles, it was found that they need to enhance the muscular power of their, throwing arms and lower limbs.
