为了揭示不同等级跳远运动员的起跳技术特征 ,为跳远的教学和训练提供理论依据 ,笔者通过高速摄影等方法 ,对 13名二级以上男子跳远运动员的技术数据进行解析统计处理。结果发现 ,一、二级运动员上板积极 ,起跳过程中不同运动员身体重心水平速度有较大差异 ,水平速度损失率也存在较大差异 ,垂直速度则无明显差异 In order to reveal the technical characteristics of take-off of different long-jump athletes and provide theoretical basis for long-distance teaching and training, the author analyzed and statistically analyzed the technical data of 13 second-class and longer-term male athletes through high-speed photography and other methods. The results show that the first and second class athletes on the board are active, and the different athletes’ body center of gravity have great differences in the horizontal speed during the take-off, the horizontal speed loss rate also has a big difference, while the vertical speed has no significant difference
