| 摘 要： | 目的：总结和借鉴优秀运动员的技术特点，应用BioRow赛艇技术测试分析系统对里约奥运会奖牌获得者段静莉划桨技术动作特征进行分析，提供相应技术参数供参考。方法：通过实船测试获得段静莉各个划桨阶段的技术参数，从桨叶控制技术、划桨风格和艇速及艇加速度三方面对段静莉的划桨技术特征进行分析总结。结论：(1)段静莉的拉桨阶段的桨叶控制有待提高，特别是桨叶入水打滑角度和桨叶出水打滑角度均偏大，桨叶入水深，不利于拉桨后期做功效率；(2)段静莉回桨阶段桨叶控制技术良好，桨叶轨迹稳定性较良好，桨叶高度适中；(3)段静莉的划桨风格属于“卢森博格”的中发力模式；(4)艇速及艇加速度是评价运动员划桨技术简单直接有效的方式。

| Abstract: | Purpose: This paper summarized and drew lessons from technique characteristics of elite athletes. It analyzed stroke technical movement characteristics of Duan Jingli, a Rio Olympic medal winner, and provided corresponding technical parameters for reference through BioRow technique test and analysis system. Methods: The technical parameters form different stroke phases were obtained through the real-boat test. Stroke technique characteristics of Duan Jingli were analyzed and summarized from blade control technique, stroke style and speed of boat and acceleration of boat. Conclusions: (1) Duan Jingli''s blade control technique at pulling phase needed to be improved, especially bigger slip angle of blade entry and release and deep blade entry. They were all not conducive to work-efficiency in late pulling phase.(2)Duan Jingli''s blade control technique at recovery phase was good, which was represented as good track stability of blade and appropriate height of blade.(3)Duan Jingli''s stroke style was Rosenberg''s medium power mode.(4) It is the simple and effect way to evaluate stroke technique of athlete by speed of boat and acceleration of boat. |
