摘要
以第28～30届奥运会田径各项目男、女子前三名为依据,运用比较优势理论对相对优势集团田径项目群的比较优势特征进行了对比研究.结果表明：世界田径相对优势集团各国男、女子等级项目群各不相同且优势程度各异；各国整体相对得分能力与项目相对竞技实力均呈动态变化,男子方面美国整体竞技实力最强,牙买加最差.女子最强为俄罗斯,最弱为肯尼亚；美国男子全能平均得分能力最强,女子则为俄罗斯竞走,英国短跑无论男子还是女子均最弱.我国田径发展的当务之急是延长运动员最佳竞技阶段持续时间,完善田径后备人才培养体制.
Taking the first three males and females of track and field events from 28th to 30th Olympic Games as examples, a comparative research was carried out between using the theory of comparative advantage and relative advantage groups of track and field events. It turned out that relative dominant group of world track and field had different levels of event group, and the degree of advantage vary. The overall relative ability to score in every country and relative competitive strength in the events took on dynamic changes. Males from Unite States own the overall strongest competitive strengths, and Jamaica was the worst. Females from Russia were the strongest, and females from Kenya were the weakest. The USA males＇ ability of average score on the all - round event was the strongest, and the strongest ability of heel and- toe walking race belongs to Russia＇s males. Both males and females from the United Kingdom are the weakest in sprinting. As for the development of track and field in our country, it is urgent to extend the athletes＇ duration during the optimum competitive stage and to perfect training system of reserve qualified personnel.
