田径世锦赛短跑竞技成绩发展态势研究

TRACK AND FIELD WORLD CHAMPIONSHIPS SPRINT ATHLETIC ACHIEVEMENT DEVELOPMENT RESEARCH

竞技成绩发展态势研究能有效把握未来竞技发展方向.借助文献资料法、数理统计法对世锦赛短跑项目的竞技成绩进行归纳分析,寻找竞技成绩发展变化规律;借助递进系数、环比动态、定基比等数据分析认为:受领军式人物博尔特的影响,男子项目竞技水平在大幅波动下向着更高水平前进,而女子项目经过前期的加速提升后趋向于稳定发展,没有形成有效性突破.人类挑战速度极限的步伐不会停止,未来短跑项目的发展依然任重而道远.

The development trend of competitive performance can effectively grasp the future development direction of competitive. Using the literature material law, the mathematical statistic method for the world championships sprint athletic performance are summarized and analyzed, and looking for athletic performance development and changes in the law, with the data analysis of progressive coefficient, chain dynamic, fixed base etc. it is considered that affacted by the leader Usain Bolt, the man competitive project level forward toward a higher level, and women after pre accelerated promotion tends to astable development there is without effective breakthrough. The step for limit chanllege will not stop, and there is a long way for the sprint events in the future.
