运用三维测力台系统和红外光点运动分析系统同步测试的方式，定量分析运动员杠铃负重半蹲力量素质各参数指标与负荷重量之间的相互关系；定量分析运动员半蹲力量素质各参数指标最大值与其弹跳高度的相互关系。为运动员力量素质训练内容的定向化、定量化提供科学的理论依据。
By means of the synchronous testing of the three-dimensional dynamometer system and the infrared point motion analysis system, the relationship between each index and the weight of load of squat weight is analyzed quantitatively. The index of each parameter of squat strength of athletes is quantitatively analyzed Value and its bounce height of the relationship. It provides a scientific theoretical basis for the orientation and quantification of strength training content of athletes.
