The authors selected 85 freshmen not majoring in physical education, used instruments such as BIODEX ISOIINETIC dynamometer and Telemyo2400DTS16 channel surface myoelectricity system to test such index data of the students as flexion leg hard pull, lower limb stamping strength, flexion arm strength, hip joint extensor strength, pull-up and grip strength, carried out a regression analysis, and revealed the following findings: as for the male stu-dents’ flexion leg hard pull, its coefficient of correlation with lower limb stamping strength as a laboratory standard test index was up to 0.913, its coefficient of correlation with hip joint extensor strength as a laboratory standard test index was 0.653, its coefficient of correlation with flexion arm strength as a laboratory standard test index was 0.724; as for the female students’ flexion leg hard pull, its coefficient of correlation with lower limb stamping strength as a laboratory standard test index was up to 0.745, its coefficient of correlation with hip joint extensor strength as a laboratory standard test index was 0.463, its coefficient of correlation with flexion arm strength as a laboratory standard test index was 0.559. The said findings indicate that flexion leg hard pull can be used as a whole body muscle strength quality evaluation index.
