一、前言: 田径运动中的投掷项目,包括掷标枪,都可被称为是以人体最大速度完成的非周期性运动。由于这种速度在很大程度上决定着投掷项目取得成功最重要的先决条件——构成取得最远投掷距离关键的器械出手速度,所以速度素质对于投掷运动员来说就至关重要了。本文的目的就是通过分析速度在掷标枪过程中所起的作用使我们对掷标枪技术有一个更为全面的了解,包括以下几个方面内容: ·明确速度及其在投掷项目中所起的作用。 ·分析掷标枪的不同动作阶段。 ·研究速度在掷标枪最后用力动作中的重要 I. Foreword: Throwing items in track and field, including throwing javelins, can all be said to be non-periodic movements done at the maximum speed of the human body. Because this rate largely determines the most important prerequisite for the success of the thrown project - the speed at which the instrument, which is the key to getting the farthest away from the throw, is of paramount importance, speed qualities are of paramount importance to throwing athletes. The purpose of this article is to provide a more complete picture of throwing gun technology by analyzing the speed’s role in throwing a javelin, including the following: • Clarify speed and its role in throwing projects . Analyze the different stages of javelin throwing. · It is important to study the speed of the final javelin throwing
