Objective:to investigate the effects of genetic polymorphism on achievement of speeding projects , in or-der to find suitable gene type for Chinese elite athletes ’ sports and provide theoretical basis for more scientific and accurate selection .Methods:basing on the genetic polymorphism of individual differences , using information tech-nology method , it comparative analyzes the top eight total of the speeding projects among the intercontinental coun -tries to find the root cause of the athletes creating one by one myth in the sports world .Conclusion:gene polymor-phism can be used as athletes selecting molecular markers .Suggestion:carrying out the study on the correlation be-tween the gene polymorphism of people in different regions and sports , has an important research value for our country to seek excellent athletes .%目的：探讨基因多态性对速度类项目成绩的影响，以期为寻找适用于我国优秀运动员相关运动基因型提供理论依据，从而使运动选材更趋向科学性和准确性。方法：根据基因多态性所表现的个体差异，通过信息技术方法，对各洲际国家之间在速度类项目中，前八名总数进行比较分析，剖析运动员在世界体坛上创造一个又一个神话的根本原因。结论：基因多态性可以作为运动员选材分子生物学标记。建议：开展我国不同地区人群的基因多态性与运动的关联性研究，对我国寻求优秀运动员具有重要的研究价值。
