摘　　要：女子争先赛、女子团体竞速赛项目是我国2012年伦敦奥运会冲击金牌的重点项目。分析和评价短距离自行车运动员竞速能力的内在特征和规律,研究表明,争先赛200m的变化趋势为:运动员从俯冲阶段进入第一个100m时速度不断提高,反映速度耐力水平的第2个100m速度略微降低,说明绝对速度高低与项目竞速能力特征要求是匹配的,我国运动员郭爽具备奥运冲金实力。女子团体竞速赛中宫金杰的个人专项爆发力或者起动技术优于其他运动员。在重视个人专项爆发力的训练的同时也要保证其在第1圈后125m的速度耐力水平,从而保证第2圈运动员具备与个体相适应的速度进行第2圈的冲刺。可以筛选具备优秀起动能力,绝对速度能力和速度耐力运动员进行组合,优化配置。Women＇s sprint and team＇s sprint have potential to get gold medal event for China in 2012 London Olympics. By means of analyzing and evaluating the inherent characteristics and patterns of indoor cycling athletes＇ racing ability, it support for gold medal events of China ~s cycling in provides theoretical insurance and practical the London Olympics. Studies have shown that the velocity trend of 200m Sprint is： the velocity from diving stage to the first 100m keeps increasing. The second 100m which reflects the athlete＇s speed endurance is relatively low. This indicates that absolute velocity matches the requirements of racing ability characteris- tics. In women＇s team sprint, GONG Jing-jie＇s specific explosive strength and starting ability is superior to other athletes. We should ensure the speed endurance in the 125m after the first circle as well as valuing the training of specific explosive strength, in order to make sure that the athlete be provided with individual adaptive speed in the second circle. We can select those athletes with better starting ability, absolute velocity as well as speed endurance to optimize the team.
