摘要
本文通过对陕西省王峥、张莉、张叶伟等省队优秀女子运动员采用文献法、专家访谈法、生物力学测试方法和数理统计法等研究方法对投掷不同重量铅球的动作技术进行分析,结果表明:①不同负荷对链球旋转投掷技术在各个阶段的运动学参数存在差异。②不同负荷在教学和训练过程中应该采用相对的质量。③不同负荷在链球投掷训练过程中,建议选球重量与标准球重量差异不超过1.5公斤,否则可能对标准球投掷技术的技术结构与技术节奏产生负面影响。
By research methods of using expert interview,biomechanical testing method and mathematical statistics to conduct analysis on action techniques of throwing different weight shot for Shaanxi outstanding female athletes,such as Wang Zheng,Zhang Li,Zhang Yewei etc.The results show that: ①it exists in differences for kinematics parameter of different load to hammer throw rotation throwing technology in various stages.②relative quality should be adopted for different load in the teaching and the training process.③different load in the training process of hammer throw,difference between weight of choosing the ball with weight of standard ball should not exceed 1.5 kg,otherwise,it is possible to engender negative impact on technical structure and technical rhythm of throwing techniques of standard ball.
