Study On The Development Of Lower Limb Flexibility And Muscle Strength Of Junior Female Football Players By PNF Traction

Football is an adversarial sport in the same field.It not only needs strong muscle strength to support the player's antagonistic ability,but also needs good flexibility to exert its technical action to the utmost.And the flexibility of the lower limbs and the muscle strength of the lower extremities are two important physical qualities that can not be ignored for our junior high school women football players.Most domestic coaches attach more importance to the training of the lower limb muscle strength of the team members.PNF stretch training has a good effect on athletes' flexibility,but the development of muscle strength is still controversial.With traction training becoming more and more important in the field of sports and rehabilitation Seeing,pulling on all aspects of the human body and its mechanism of action,but also gradually attracted the attention of scholars from all walks of life.PNF technology gradually entered the sports field with a new form of traction.After entering the sports field,the PNF technology has played a more obvious role in many aspects,and some studies have shown that PNF stretch training has a positive effect on the flexibility of the players in other sports.It has even a boost to its muscle strength.According to the characteristics of football and the physical characteristics of women football players in junior high school,this paper sets up the theoretical basis and practical operation principle of the existing PNF pulling technique in accordance with the characteristics of football and the physical characteristics of women football players in junior high school.Appropriate,suitable for junior middle school female footballer's PNF pull-down way,carries on the scientific pull effect appraisal,further studies the junior middle school female football player's lower limb flexibility and the development of the muscle strength of the PNF traction to the junior high school female footballer's lower limb flexibility and the muscle strength development.In this paper,by means of literature,questionnaire,experiment,mathematical statistics and other research methods,the women football team members of Nanya Middle School in Changsha City are divided into groups.The conclusions of the study are as follows:1.PNF traction is more favorable than traditional traction to promote the development of lower limb flexibility(hip flexibility,ankle flexibility)of junior high school women football players.2.Compared with traditional traction PNF traction can promote lower limb endurance of junior high school female football players,but it has no obvious effect on lower limb muscle burst PNF traction and traditional traction.3.PNF stretching method can make lower limb flexibility quality and lower limb muscle endurance develop harmoniously.It is an effective auxiliary training method.This characteristic is the greatest advantage over other stretching methods.
