摘要
采用Track Man雷达追踪系统,测得35名高尔夫球手进行1号木杆击球的23项指标的316组数据。以主成分法对其进行因子分析并提取公因子,旨在构建合理的1号木杆击球效果的综合评价模型。结果表明:第1公因子控制击球的速度,反映击球的总距离;第2公因子控制挥杆的平面,反映球的飞行弧度;第3公因子控制击球的方向,反映击球的精准度;第4公因子控制击球的角度,反映弹道高度。通过构建1号木杆评价击球效果的因子分析综合模型,得出在高尔夫专项训练中应当重视对击球距离综合因子、击球弧度综合因子、击球准度综合因子、击球高度综合因子的监控与优化。
Using the Track Man radar tracking system,316 data sets of 23 indicators of 35 golfers in the Driver shot were measured. The principal component method is used to analyze the factor and extract the common factor,aiming at constructing a comprehensive evaluation model of the hitting effect of the Driver. The results show that the common factor 1 is controls the shot speed,which reflects the total distance of the shot; the common factor 2 is controls the swing plane,which reflects the flight path of the ball; the common factor 3 is controls the shot direction,which reflects the accuracy of the shot; the common factor 4 is controls the shot angle,which reflects the height of the trajectory. Conclusion: A comprehensive factor analysis model for evaluating the hitting effect of Driver was constructed; In the golf special training,we should pay attention to the monitoring and optimization of the hitting-distance comprehensive factor,the hitting-path comprehensive factor,the hitting-accuracy factor and the hitting-height comprehensive factor.
