通过查阅相关的文献资料,运用灰色关联分析对我国部分优秀男子背越式跳高运动员一次比赛中所具备的身体素质与专项成绩之间进行定量化分析。结果表明:研究对象跳高专项成绩与身体素质的GM(l,n)动态模型中,专项成绩的发展系数(a)值大于零,说明研究对象主要身体素质指标与专项成绩的发展呈不协调状态,即绝对速度和专项力量,特别是腿部和踝关节的专项力量是影响专项成绩的关键因素。
By referring to the relevant literature and using gray relational analysis, we can quantitatively analyze the physical quality and special achievements of some elite male backless high jumpers in China. The results show that the development coefficient (a) of the special grade is greater than zero in the GM (l, n) dynamic model of the subject’s performance of jumping high and the physical quality, indicating that the development of the main body quality index and the special grade of the subject is uncoordinated , That is, the absolute speed and special forces, especially the special forces of the legs and ankles are the key factors affecting the special performance.
