国径项目是综合比赛的重头戏,项目多,金牌也多,最能体现一个国家的竞技水平。田径通常包括田赛和径赛两部分。径赛比的是时间,需要选手在最短时间跑(走)完规定的距离;而田赛通常看谁跳得高,跃得远,掷得距离长。田径比赛跑跑跳跳,看似简单,可是真正要达到一定的水平,却要融合体能、技术和意志力,需要掌握先进的技术。投掷项目就是这样,非常讲究技术,而这里又以投掷项目中的旋转技术最为独特。要想把手中的重器械投掷得远,选手就需要在掷出前给器械以较高的运动速度,然后再有力地投掷出去,这样 The national trail project is the highlight of the comprehensive competition. There are many projects and many gold medals, which can best reflect the competitive level of a country. Track and field usually includes two parts of field competitions and track events. It is time for the match to be raced. Players are required to run (walk) for a specified distance in the shortest possible time. Field matches usually look at who jumps high, jumps far, and throws long distances. Track and field competitions seem to be simple, but to achieve a certain level, we must integrate physical energy, technology and willpower, and we must master advanced technology. Throw project is like this, very particular about technology, and here is the most unique in the rotation technology in the throwing project. To throw a heavy instrument in the handle far, the player needs to give the instrument a higher speed before throwing it, and then throw it out vigorously.
