基于灰色模型的宁夏青少年田径运动成绩相关性分析

Ningxia Youth Track and Field Correlation Analysis Based on Grey Model Theory

运用文献资料法、数理统计法、访谈法,对宁夏2000—2009年青少年田径比赛成绩的每个分项的相关数据进行累加生成数列后,采用一维灰色模型理论,进行了回归方程分析,以期了解宁夏青少年田径运动近10 a的发展态势,为改进青少年田径运动的训练方法和提高运动成绩提供了理论依据.

By using literature,interviews,statistics methods,every sub-related data of Ningxia youth track and field from 2000 to 2009 is accumulated and generated to series,then,one-dimensional gray model theory is used to get regression equation analysis.As result,Ningxia youth track and field development trend in recent years will be known for providing theoretical basis of both performance enhancement and improving training method of youth athletics.
