本文通过文献资料法和数理统计法,对国内外优秀中长跑运动员进行研究,并针对运动员的全程速度明显提高,呈现两头快、中间稍慢的速度特点,提出要培养优秀的中长跑运动员必须在速度训练上下工夫,强调了在发展速度能力中应以短为主,长短结合,速度训练应贯穿中长跑训练的全过程。阐述速度耐力在中长跑训练过程中的重要性,强调耐力跑训练要有一定的速度约束,运动员的高速度能力是提高中长跑成绩的关键。 In this paper, we study the domestic and foreign excellent middle and long-distance runners through the methods of literature review and mathematical statistics, and raise the overall speed of the athletes significantly, showing the characteristics of fast speed in both ends and slower speed in middle speed. Speed ​​training work hard, emphasizing the ability to develop speed should be short, the length of the combination of speed training should run through the whole process of middle and long distance training. The importance of speed endurance in middle and long distance training is expounded. It is emphasized that endurance training should have certain speed restriction. The high speed ability of athletes is the key to improve middle and long distance performance.
