通过运用三维运动学分析的方法，对我国女子20km竞走运动队员刘虹的技术进行研究发现，她存在步长小、步频快、身体重心上下起伏大、前倾角偏大、着地角偏大、两大腿夹角偏小、髋关节灵活性差、摆动不积极等缺点。建议在以后的训练中主要发展以髋关节为核心的力量和柔韧，努力提高髋关节和摆动腿摆动的幅度，来增大步长。

By using methods for three-dimensional kinematical analysis, the authors studied techniques of LIU Hong as a women 20-meter race walking athlete in China, and revealed that she had the following defects： her stride was too short; her pace was too fast; her body center of gravity fluctuated too much; her forward tilting angle was too big; her landing angle was too big; her leg included angle was too small, her hip joint flexibility was poor; her swing was not active. The authors suggested that in future training she should mainly strengthen the strength and flexibility of her hip joint, and strive to increase the swing amplitude of her hip joint and swinging legs to increase her stride.
