Kinematic Analysis on Last Two Strides of Run-up of our Elite Female Long Jumpers

In this paper,the last two strides of run-up of our elite female long jumpers were analyzed by using literature review,survey,imaging techniques,image analysis and mathematic statistic method,some relevant technical data were also analyzed.Results: the last two strides of elite long jumpers abroad show the changing tendency from big to small;however,the last two strides of our long jumpers are comparatively small,without distinct speed change,showing a flat trend,characterized by fluctuation in gravity centre from high to moderate to moderate.
