| 摘 要： | 对崔文华在第八届全运会上抓举200.5 kg 超世界记录的抓举技术作了现场拍摄,并用国产爱捷录像解析系统进行了解析,表明:1)崔文华发力阶段杠心穿越重心轨迹,杠心贴着重心向上而行,而两心(杠心和重心)相对最大偏差明显偏小;2)发力后杠心上抛速度大;3)杠铃上抛最高点相对高度(与身高的百分比)高;4)支撑阶段身体下落快,人体重心向下的加速度超过了重力加速度;5)采用滑杠技术,突出“低”、“稳”支撑的特点。

| Abstract: | In the 8th National Game of China Cui Wenhua snatched 200.5kg which exceeded the old snatch world record. His technique was video recorded and analyzed on the Engine Video Analysis Performance System. The results showed:1) His barbell center got up through the trajectory of the body center, keeping close to it with less relative maximum deviation. 2) Cui's barbell center went upward with large vertical velocity. 3) The relative maximum height of the upcast barbell center (the percentage relative to the height of the body) was high. 4) During the jump phase, Cui produced downward acceleration with the absolute value more than that of the acceleration of gravity (9.8m/s 2). 5) The slipping technique was adopted giving prominence to the characteristics of low and stable receiving point. |
