Experimental Research On Application Of PNF Stretch Method In Hurdle Teaching In Normal Colleges

This study aims at the application of PNF stretch method in the teaching of hurdle in normal colleges in the prescribed teaching time from the specific Angle of hurdle,hip knee and ankle joint Angle,FMS functional movement screening,sports quality,hurdle performance and technical evaluation,etc.Through the contrast analysis of the experimental group and control group in experiments before and after the experiment again transverse analysis comparing two groups of related data of the test results,to explore the traditional stretching method and the PNF stretching method compared to effectively within the time prescribed by the teaching learning and mastery of the technology to improve the hurdles result and hurdles,provide perfect hurdle teaching methods and training system.Therefore,it can be used as a reference for the new curriculum reform in recent years to effectively improve students’ hurdle performance and hurdle technology in the prescribed teaching period.This study of Shanxi normal university sports institute 2020 level,in the common class for the sports education professional athletics as experimental object,mainly using the method of documentary,teaching experiment and other research methods,after 12 weeks of stretching training,after the experiment is aimed at students ankle angles hurdles special Angle,hip,knee,FMS functional action screening,movement quality,hurdles and skill evaluation,After comparative analysis,and according to the data change degree of each index of the practice object before and after the experiment,we draw a conclusion:(1)on the hip knee ankle angles,students use PNF stretching method in the aspect of the knee and ankle than traditional static and dynamic stretching method has significantly increased,to the hurdles special flexibility quality and hurdling technique ability has a positive effect,so the student to carry on the hip knee ankle flexibility training should be more when the PNF stretching method is adopted.(2)In terms of the specific Angle of hurdle,students using PNF stretching method have significantly improved the amplitude of bending knees in sitting position compared with the traditional static and dynamic stretching method.(3)In terms of FMS functional movement screening,the effect of students using PNF stretching method in hurdle step is significantly improved compared with traditional static and dynamic stretching method.(4)In terms of sports quality,there was no significant difference between male and female students using PNF stretching method and traditional static and dynamic stretching method.(5)In terms of hurdles and technical evaluation,the performance of male and female students using PNF stretching method in hurdles and technical evaluation is significantly higher than that of traditional static and dynamic stretching method,which can provide guidance and training means for beginner hurdlers.(6)In the general course of hurdle in normal colleges,PNF stretching method can stimulate students’ learning motivation and interest more than the traditional static and dynamic stretching method,solve the problem of boring teaching process and greatly enrich the diversity of teaching methods.
