Effect Of Functional Training On The Muscle Power Balance Of Knee Joint Flexors And Extensors Of Greco-Roman Wrestling

Functional training,as a research hotspot in competitive sports,has received increasing attention from researchers and coaches in China.However,due to the late introduction of functional training in China,the theory and practice are disconnected when applied in competitive sports,and there is no complete method system for the application of a particular sport.Classical wrestling is a skill-dominated fighting project.It is a sports event in which two people are in physical contact,fighting with bare hands,and being highly competitive.Because of its strong antagonism,fierce competition,coupled with high exercise intensity,technical movement changes and irregularities,it has high requirements for athletes' physical fitness in all aspects.In daily training,due to the influence of competition rules,coaches and athletes pay more attention to the development of upper limb strength and ignore the development of lower limb strength,resulting in weak strength of the posterior femoral muscles and uneven strength of the knee flexors and extensors,which affects the athletes' knees.The stability of the joints increases the chances of athletes knee injury.Therefore,how to use the functional training method of lower limbs to improve the strength of the posterior thigh muscles of classical wrestlers is a problem to be solved now.This article uses the literature method,expert interview method,experimental method and data statistics method to design the training plan based on the actual needs of male classical wrestlers in Shandong Province.Twenty classical wrestlers were tested for isokinetic strength of the knee joint to analyze the differences in muscle strength of the knee flexors and extensors.The selected athletes were divided into two groups,one was the experimental group and the other was the control group.There was no significant difference in the basic conditions of the two groups of athletes.Functional training programs for lower limbs and traditional lower limb strength training were designed for two groups of athletes for 8 weeks of training.After 8 weeks of training,the two groups of athletes were tested again for isokinetic strength of the knee joint.Analyze and compare the two sets of data,and draw the following conclusions;(1)By training the experimental group and the control group for 8 weeks in different training modes of the lower limbs,the test results show that both the experimental group and the control group have a positive impact on the peak moments PT / BW of the knee flexors and extensors.Among them,the peak torques PT / BW of the flexor muscle groups of the left and right knee joints of the experimental group were significantly higher than those of the control group,but the increase of the quadriceps muscle strength of the control group was higher than that of the experimental group.(2)Through a comparative analysis of the isotopic muscle strength PTR of the two groups of subjects,the results show that there is no significant difference between the experimental group and the control group(P> 0.05),but the mean name can be seen from the experimental group To be superior to the control group,the weak side muscles of the experimental group have been greatly improved,so that the muscles of the same name of the left and right knee joints are more balanced.(3)Through a comparative analysis of the knee flexor and extensor group ratio H /Q of the two groups of subjects,it can be seen that the functional training of the lower limbs for 8 weeks makes the flexion and extension ratio of the left and right knee joints in the experimental group more balanced,compared with the control group.There were significant differences(P less than 0.05).It has been confirmed that functional training of the lower limbs plays an important role in the development of the strength of the posterior thigh muscles of a classical wrestler.(4)Through a comparative analysis of the knee joint flexor and extensor group endurance ratio ER of the two groups of subjects,the results show that there is no significant difference between the two groups of data(P> 0.05),but it can be seen from the comparison of the mean that the experimental group The endurance ratio of the knee flexors and extensors was better than that of the control group.
