摘　　要：运用录像观察、数理统计、逻辑分析等方法,对第15届世锦赛女子马拉松运动员竞技特征进行分析,结果显示:在女子马拉松决赛前六名及中国运动员赛跑中,运动员速度变化形式有“全程相对匀速”、“前慢后快”、“前快后慢”三种类型;优秀运动员各段的速度与总成绩的相关性分布不均匀,30km^40km的速度与运动员的总成绩相关性最大;夺得奖牌的运动员首先以较快的速度进入第一集团,25km以后速度变化明显,形成鲜明对比,三位中国优秀运动的相对速度与迪巴巴之间还存在差距,后半程速度有待进一步提高,在日常训练中应加强速度和耐力训练。By using the methods of video observation,mathematical statistics,logical analysis,this paper studies the competitive characteristics of the 15th the women’s marathon World Championship.The result shows that,there are three types of speed change such as“relatively balanced speed during competition”,“low speed before and high speed after”,“high speed before and low speed after”in the women’s marathon final of the top six athletes and Chinese athletes;outstanding athletes have an uneven correlation between speeds in different stage and total points,the most correlation is that between the speed of 30km^40km and total points;athletes win medals rank in the first group with quicker speed,whose speed changes obviously after 25km and have a great gap compare with Chinese athletes;the relative speed of three Chinese outstanding athletes still remain gap with Dibaba,the speed of second half need to improve through strengthening speed and endurance in daily training.
