摘要：林丹、李宗伟是中、马羽毛球届顶尖男单选手，他们的比赛被球迷和媒体戏称为“林李大战”。北京奥运会、伦敦奥运会、里约奥运会，林李大战都出现在决赛和半决赛阶段，反映林李长期处于男单领先水平。研究他们的对抗有助于揭示当代男单打羽毛球技战术的发展趋势，为未来的羽毛球训练提供参考，因此具有较高的研究价值。

本文通过文献资料法、录像法、数理统计法等研究方法，通过对31届里约奥运会“林李大战”基本竞技过程的研究，发现：

（1）从接发球频次分布特征看，发球落点区域频次由高到低依次是2、3、1、5、4、6区。技战术特点是网前选择大于后场。接发第一拍技术中，李宗伟的使用不同技术的频率由高到低依次是：搓球、挑球、平推，林丹依次是挑球、搓球、平推。

（2）从多拍结构频次分布特征来看，最多42拍，最少2拍。其中6拍的结构特征最为显著，技战术特点为发挥自身优势。

（3）从得分能力看，主动得分为主要得分形式，比赛中前五拍获得主动的一方更容易得分。林丹在接发球方面的得分高于李宗伟。

（4）在相持初级阶段、相持中级阶段、相持末级阶段主要技术类型由高到低依次是：搓球、高远球、劈吊球、杀球、挑球、扑球、推球、抽球。

建议：（1）在日常训练中应当加强网前的练习，培养运动员的手感，并指导其在比赛中大胆的运用自己的网前技术。(2)加强对运动员在相持阶段的稳定性的训练，让其在较长时间的对抗阶段也能够充分的完成技战术。(3)在训练中要加强训练相持阶段的稳定性的训练。
