摘要
本研究以无创检测电脑诊脉仪为测试手段,通过对三百余例优秀径赛运动员七千多个血循环运动力学数据分析研究:1.优秀径赛运动员血循环动力学指标的常模参考值;2.运动员成绩和这些指标的关系;3.这些指标是否可辅助判别运动员适合哪种距离跑。通过逐步回归分析,发现部分血循环动力学指标与径赛运动成绩相关,逐步回归的结果有较高的精度,通过多元逐步判断分析发现血循环动力学指标还可帮助我们判断某运动员适合长跑还是短跑,可作为选材的辅助方法。
More than 300 elite track athletes were tested with a computerized pulse insturment and some 7,000 data connectedwith the dynamics of blood circulation were obtained.The aims of the study were:1.to work out a referene module in thedynamics of blood circulation:2.to determine the relationships between the runners'performances and the indices;and 3.tofind out whether these indices are useful for deciding what running distance is most suitable for each runner.Through step-regres,sion it was found that some of the indices were related to the runners'performanoes;the results of step-regression werepretty precise;suitable for each runner.
