1 问题提出短跑是各项体育运动的基础。近年来,随着竞技体育水平的提高,短跑技术的发展也不断完善,世界纪录屡屡被刷新,男子百米世界纪录已达9″85,女子百米世界纪录达10″49。近几年来,我国的百米水平在一定程度上有所提高,男子百米纪录达10″20,女子百米纪录达11″02,但就世界水平而言,仍存在很大的差距。表1是1995年我国与世界百米成绩的对照。若今后不进行技术创新,提高训练质量,将会与世界水平的差距越来越大。
1 PROBLEM PROBLEMS Sprinting is the basis of all sports. In recent years, with the improvement of competitive sports, the development of sprint technology has been continuously improved. The world record has been repeatedly refreshed. The world record of men’s 100 meters has reached 9 “85 and the world record of women’s 100 meters has reached 10” 49. In recent years, the 100-meter level in our country has been somewhat improved. Men’s 100-meter record reached 10 “20 and that for women’s 100-meter record reached 11” 02. However, there is still a big gap in world standards. Table 1 is a comparison between the achievements of China and the world in 1995 in 1995. If we do not carry out technological innovation in the future and improve the quality of training, we will find that there will be a widening gap with the world level.
