通过平面定机摄影获得优秀女子竞走队员竞走技术的部分生物力学特征。发现我国优秀女子20km竞走运动员不论是个体还是群体其变化值离散程度均较高，训练中应当加以改进。建议在固定合理稳定的步长基础上加快步频，从而提高运动成绩。
通過平麵定機攝影穫得優秀女子競走隊員競走技術的部分生物力學特徵。髮現我國優秀女子20km競走運動員不論是箇體還是群體其變化值離散程度均較高，訓練中應噹加以改進。建議在固定閤理穩定的步長基礎上加快步頻，從而提高運動成績。

Part of the biomechanical characteristics of outstanding female race-walkers' techniques is gained through plane machine setting photography and it is found that whether individuals or groups, the change value dispersion degree of outstanding 20 km race walkers in China is quite high which should be improved in training. It is suggested that the walkers speed up the pace on the basis of mixed reasonable stable step length so as to enhance athletic performance.
