摘要:: 蛙泳作为我国竞技游泳的传统优势项目一直备受关注。为进一步帮助运动员优化技术与提升成绩，对全国游泳冠军赛男子50m 蛙泳运动员的技术特征进行研究。运用文献资料、视频解析、数理统计、案例分析等研究方法，分析和阐释我国高水平男子50m蛙泳运动员的技术特征。结论:（1）冠军孙佳俊同国内选手相比，各个分段的用时与游速皆领先，但主要是凭借卓越的出发技术和破水衔接能力夺得冠军。（2）孙佳俊和覃海洋同亚当·皮蒂相比，在出发15m时间、划水次数与游速上差距悬殊。（3）国内选手奖牌组与非奖牌组相比，在出发反应时、出水距离、划次、划幅与划频上并无显著性差异，但在出发15m时间、途中游时间、冲刺5m时间和游速上具备显著性差异。

Abstract:: Breaststroke,a traditional advantageous event of competitive swimming in China,has been attracting much attention.To further help breaststrokers optimize their technique and improve their performance,the technical features of men’s 50m breaststrokers in the National Swimming Championships were studied.The data of the technical features were analyzed and explained by using the literature method,video analysis method,mathematical statistics method,and case study method.The results showed that:(1）The champion Sun Jiajun was ahead of domestic competitors in terms of time and swimming speed in all sections.However,he won the championship mainly by his excellent starting and transitions from entry to the firsttime head breakout.(2）Compared with Adam Peaty,both Sun Jiajun and Qin Haiyang were far behind in the time of the first 15 meters,stroke length,and stroke frequency.(3）There were no differences in start reaction time,distance of the firsttime head breakout,stroke times,stroke length,and stroke frequency between the domestic medalists and the nonmedalists.However,there were significant differences in the time of the first 15 meters,the time of the midway,and the time and velocity of the last 5 meters.
