The synergistic level of flexibility and strength quality of athletes is directly related to the technical play, this paper takes 20 male athletes of level 2 and above freestyle wrestling as the object, randomly divided into experimental group and control group to carry out the research on the influence of flexibility and strength training. The test indexes covered functional screening and athletic performance, and SPSS26.0 was used for repeated measures ANOVA and independent samples T-test. The results showed that: (1) there was no significant difference between the two groups in the pre-test and the six sports performance indicators (P>0.05), the experimental group in the post-test was significantly higher than the control group in the indicators of pull-ups and in-situ vertical jumps (P<0.05), and the score of the experimental group in the post-test of the functional screening was significantly higher than that of the control group in the post-test (17.9±1.36) (15.2±1.62). (2) Repeated-measures ANOVA showed that the variance structure of strength-dominant, jumping, speed and comprehensive indexes had their own emphasis, and the synergistic effect of training method and time on strength and speed indexes was significant. The study showed that the synergistic training of flexibility and strength can effectively improve the performance of freestyle wrestlers.
