一、前言 利用助跑投掷与原地投掷成绩差的利用率,既助跑贡献率研究标枪技术,成为世界各国普遍采用的衡量标枪技术水平好坏的重要手段。我国刘世华教授多次进行助跑贡献率的研究,为我国标枪技术的诊断提供了科学的依据。 助跑贡献率大,固然说明运动员的助跑与投掷技术的衔接较为合理,但助跑贡献率大并不能完全说明和代表专项水平高,如果运动员的原地投掷成绩较低,其助跑贡献率相对就大。以我国为代表的男子标枪运动就是一个典型的例子。从旧标枪的申毛毛、普布次仁,到新枪的张连标、王文忠、陈骏麟等国手,其助跑贡 I. Preface Making use of the poor utilization rate of run-up throwing and in-place throwing, both contributing to the contribution rate research javelin technology has become an important measure commonly used by all countries in the world to measure the technical level of javelin. Professor Liu Shihua of our country has carried on the research on the contribution rate of run-up for many times, which provides a scientific basis for the diagnosis of our country’s javelin technology. Although the contribution rate of run-up is large, it shows that the connection between run-up and throwing technique of athletes is more reasonable. However, the large contribution rate of run-in can not fully explain and represent the high level of special items. If the athlete’s throw-in result is relatively low, . The typical javelin movement represented by China is a typical example. From the old javelin Shen Mao Mao, Pu Bu Tsering, to the new gun Zhang Lianbiao, Wang Wenzhong, Chen Chunlin and other countries, their tribute tribute
