摘　　要：对第30届伦敦奥运会田径项目女子400m栏决赛参赛运动员的年龄、身体形态、成绩的稳定性、比赛发挥、发挥情况和各个赛次中成绩进行分析。结果表明:参赛运动员平均年龄为25.88±2.95岁,奖牌获得者出现大龄化特征,女子400m栏运动员平均身高为174.25±4.89cm,平均身高并不是太高,但个别运动员呈现出高大化发展特征;半决赛阶段运动员成绩稳定性最好,决赛阶段成绩离散度最大,三个赛次呈现出"低-中-高"状态,这与运动员对赛次中发挥情况的重要性相吻合,正好适应运动员在不同赛次的发挥情况;受个人竞技能力所限,女子400m栏参赛运动员在决赛阶段的平均发挥率最高,而预赛阶段运动员的发挥率最差,只有极少数运动员在三个赛次中表现出赛季最佳成绩。因此,在训练中应大力培养运动员尽快进入比赛状态的能力,并制定出运动员参加大赛的训练周期计划。The paper analyses the age, body shape, result stability, competitive performance and competition results of the women＇ s 400m hurdle athletes in the 30th London Olympic Games.
