摘　　要： 对2007世锦赛男子50 km竞走优秀选手的战术特征和裁判判罚情况进行分析研究。结果表明：男子50 km竞走比赛的战术运用,应考虑比赛裁判的判罚特点。判罚情况说明1-3时段是裁判执裁的重点。世锦赛50 km竞走前八名运动员速度的整体特征变化,基本上以较慢的匀加速开始,逐渐提高速度,至30-40km达到最高速度,最后10-15 km由于体力下降导致逐渐减低了速度。选手采用的战术对50 km竞走比赛成绩产生重要的影响。跟走和领走是耐力项目重要的战术特点,建议我国选手根据运动员的技术、体能特征及比赛规模、气候等制定有效和符合实际的战术计划。从训练方法、能量供应等方面做更多更细地研究。 This study analyzes the tactics and judgment of the elite 50 km men walkers in World Athletics Championships in 2007. The results show that the application of tactics in men＇ s 50kin walk should correspond with characteristics of judgment.

The entire varieties of speed of top 8 walkers indicate that they started with slow uniformly acceleration from and reached their peak speed at 30 - 40kin. During the last 10 - 15km their speed began to decline due to physical capacity descending. The walkers＇ tactics have great impact on their 50kin walk performance. Both following and leading perform as essential tactics in long distance walk. Chinese walkers＇ tactic plans depend on their technique, physical condition, grade of competition and climate.
