摘 "要:對近10屆田徑世錦賽鏈球比賽獲獎國家及比賽成績進行整理分析,并運用灰色預測GM(1.1)模型對第20屆田徑世錦賽男子和女子鏈球單項的成績進行預測。結果表明:波蘭是世界鏈球強國,世界鏈球項目競爭愈來愈激烈,且男子鏈球單項的競爭程度與女子相比更為激烈;男子鏈球單項的成績發展不穩定,且整體呈現緩慢下降趨勢;女子鏈球成績發展呈現出一種先上升后趨于穩定的態勢;第20屆田徑世錦賽男子鏈球單項的成績仍會繼續下降,女子單項的成績會有小幅度提高。

Abstract: This paper analyzes the winning countries and the results of the hammer throw in the past 10 World Championships, and uses the GM (1.1)"model to predict the results of the men's and women's hammer throw in the 20th World Championships. The results show that Poland is a powerful country in the world hammer throw. The competition of the world hammer throw is more and more intense, and the competition of men's hammer throw is more intense than that of women. The development of men's hammer throw is not stable, and the overall performance shows a slow decline trend; the development of women's hammer throw shows a trend of rising first and then stabilizing. The results of the men's hammer throw event in the 20th World Athletics Championships will continue to decline, and the results of the women's event will improve slightly.
