李娜是我国世界排名最高的网球选手，6岁开始练习网球，1999年转为职业网球选手。从网球低级别赛事一路打到四大满贯。2011年获得法国网球公开赛女单冠军，成为亚洲第一个获得大满贯单打冠军的网球选手。2013年，李娜入选全球最有影响力人物名单，2014年2月17日世界排名上升到世界第二，创造了女子亚洲选手个人排名最高记录。文章对李娜近5年的比赛成绩进行观察统计和分析归纳，最后得出李娜成绩的一些特点：按年份来看，李娜2009年、2011年、2012年的成绩起伏较大。2010年、2013年全年成绩高峰比较集中。按月份来看，李娜在年初，特别是1月份的赛事上成绩普遍处于高峰状态。经过一段时间的低谷后，在6月份左右又会出现全年的第二个高峰阶段。在年末10月份的时候又会有一个成绩的小高峰。李娜的成绩在低谷之后必会迎来高峰。
