Experimental Study On The Effect Of Enhanced Training On The Performance Of Five Meter Three-way Turn Back Run Of Physical Education College Entrance Examination Students In Hunan Province ——Take Shimen No.1 Middle School As An Ex

At present,the slogan of national sports has been deeply rooted in the hearts of the people.According to the overall requirements of the national fitness plan(2021-2025),in order to develop the sports industry and speed up the construction of a sports power,more sports talents are needed to participate in it,and the sports college entrance examination is one of the important ways to select sports reserve talents.The "five meter three-way turn back run" mainly examines the students' explosive power,sensitivity and other comprehensive qualities.According to the detailed rules for the examination and enrollment of Hunan Province in 2021,the score of "five meter three-way turnaround" is 60,which is one of the compulsory items in the physical education examination.However,from the scores of this item in Hunan Province over the years,the scores obtained by the candidates are not ideal.The overall scores of boys before conversion are normally distributed,and the scores are mainly concentrated between 8.15 s and 7.85 s,According to the conversion in Appendix 2,the scores of boys in five meters and three directions are concentrated between 80 and 90,which is a certain gap from the high score.The core of enhanced training to improve the training effect is to use muscle stretch contraction(SSC)to develop muscle explosiveness.It has been widely used in the special training of jumping,ball and other sports.Through the research and experimental optimization of scholars,it has been widely regarded as one of the important training methods to enhance muscle strength and explosiveness,However,there is no relevant research in the training of the five meter three-way turn back run in the sports college entrance examination.The five meter three-way turn back run is similar to the sprint and belongs to the speed sports dominated by physical fitness.However,in addition to the explosive power of the lower limbs,the sensitive quality is also an important factor affecting the performance of the five meter three-way turn back run.Combined with the opinions of relevant experts and through scientific and reasonable design,this study combines the enhanced training with the five meter three-way turn back run of Hunan sports college entrance examination,and adopts experiments to verify the positive impact of the enhanced training method on the five meter three-way turn back run,so as to provide suggestions and methods for the efficient training of sports college entrance examination students.Therefore,this paper takes the influence of enhanced practice on the performance of five meter three-way turn back run in Hunan middle school physical education examination as the main research object,and selects twelve male athletes from the college entrance examination sports specialty training team of Shim en No.1 middle school as the experimental object.Using the methods of literature,expert interview,logical analysis,mathematical statistics and experiment,the specific values are obtained,and after eight weeks of enhanced practice,the lower limb explosive force indexes of athletes before and after the experiment(30M straight sprint,barbell semi squat 1RM,standing long jump and standing triple jump)The differences of sensitivity quality indexes(pro sensitivity test,t sensitivity test and elision sensitivity test)and the results of five meter three-way turn back run were analyzed and discussed.The final conclusion is:(1)After eight weeks of enhanced experiment,the explosive level of the lower limbs of the students in the experimental group has increased significantly,so enhanced practice can become an important means to effectively enhance the explosive level of the lower limbs of the students in the physical education college entrance examination;However,the effect of improving athletes' weight-bearing squat 1RM performance is limited,and the effect of conventional strength training is better in this regard.(2)Through eight weeks of enhanced training experiment and intervention,the sensitive quality level of the experimental group has been significantly improved.Therefore,enhanced training experiment can become an important means to effectively improve the sensitive quality level of students in physical education college entrance examination.(3)After 8 weeks of experiment,the performance of the five meters and three-way return run of both the experimental group and the control group were significantly improved,and there were also significant differences between the experimental group and the control group.Traditional strength training is to improve the performance of the five-meter three-way return running by improving the explosive force level of the lower limbs.The enhanced training improves the performance of the five-meter three-way return running by improving the explosive force and sensitive quality of the lower limbs,which is more in line with the special characteristics of the five-meter three-way return running project.?...
