摘要
采用动力测试与摄像解析相结合的方法 ,对国家男子举重队占旭刚、石智勇等 9人的技术动作进行诊断和评价 ,为改进技术、提高成绩提供科学依据。研究结果表明 ,抓举测试中一些运动员引膝角度不合理 ,展髋抬体幅度偏大 ;挺举测试中张国政引膝时间较长 ,压力调整不合理。跳步动作是维持接铃支撑平衡的补偿性动作 ,运动员杠铃上送距离较大 ,造成过大的回落距离和速度。占旭刚在挺举 180 kg接铃时杠铃回落的距离和速度过大 ,再加上其退让性缓冲不足 ,下砸力过大而导致动作失败。发力后接铃支撑时 ,人、杠铃压力中心移动过大和 Fz对
By using the method of six dimensional force test, the author diagnoses and evaluates the technical movement of 9 weightlifters in order to improve the technique and provide scientific basis for improving the performance. The result shows that some weightlifters' movement of knee is unreasonable, the hip and trunk with horizontal is bigger in snatch. ZHANG Guo-zheng's movement time of knee is longer and press adjustment is unreasonable. Leap movement compensates the balance of maintaining hold bar support. Barbell's movement displacement is too high in jerk and ZHAN Xu gang's technique is like this in jerk 180kg.
