摘要
采用文献资料法、调查法、影像拍摄法、图像解析法和数理统计法,对我国优秀女子跳远运动员助跑最后两步进行解析,并选择相关技术参数进行分析。研究结果表明:国内外优秀运动员助跑最后两步步长的变化趋势同为"大→小",但我国女子跳远运动员步长相对较小;速度没有显著性差异,呈现平缓型;重心波动呈现"高—中—中"特征。
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
