| Children’s physique is related to the future of our country.While building a well-off society in an all-round way,the physical health of primary school students is highly valued by the whole people.National physical health test data directly reflects the status of primary school students’ physical fitness indicators and the implementation of sunshine sports activities is an important measure to improve the physical health level of all students.In this study,the students of 12 classes in grade 10 of Hanzhong normal primary school were selected as the research object.10 students were selected from each class for a half year experiment.Among them,60 students were given rope skipping training three times a week,and the other 60 students were given regular physical exercise(and were not required to take extracurricular exercise),which exercise for 30 minutes each time for experimental comparison.Before and after the experiment,according to the national physical health standards,the pre-test and post test were carried out.In the process of the experiment,the subjects in the experimental group were given short rope jumping special skills training and special physical training,so as to improve the students’ physical quality.Then,by comparing the test results before and after the experiment,we can judge whether the short rope jumping can affect the physical quality of the fourth grade students,aiming at improving the physical quality of teenagers Physical health.This study uses the methods of literature,physical test,control experiment,mathematical statistics and other research methods to test and evaluate the physical fitness of the fourth grade in Hanzhong normal primary school.The students of Hanzhong normal primary school have mastered basic rope skipping,so the main purpose is to improve the students’ physical health in the process of rope skipping,and cooperate with special rope skipping physical training in the experiment.After determining the experimental personnel,the test items are weight,vital capacity,50 meter running,sitting forward,one minute rope skipping,sit up according to the national physique test standards.Before the experiment,120 students were tested.In the test,according to the requirements of the national physique test network,the students in our school were tested before and after the experiment,and statistical analysis of the data.Results:(1)after 12 weeks of experimental intervention,the system test scores of subjects in the control group and the experimental group were improved,especially the number of rope skipping in one minute and vital capacity.After statistical analysis of the score data before and after each test,the P values were less than 0.01,so there were significant differences before and after each test.In the physical fitness test results before and after the control group,in the data comparison before and after the physical fitness test in the control group,the P values were significantly greater than 0.01.Although all the results were improved,the effect of the control test group was not significant.In the comparison of the physical fitness test results of men and women in the experimental group and the control group,the intervention effect of men’s physical fitness test results is better than that of women,but there is no significant difference between men and women in the control group.Research conclusions:(1)after using the national physical test standard to evaluate the subjects,it is concluded that the subjects can enhance their physical quality after physical exercise,but the different sports and the arrangement of sports load intensity will have different effects on students’ physical health;(2)After the intervention of short rope skipping skills and physical fitness,the physical test scores of the subjects in the experimental group were significantly improved,which confirmed that short rope skipping can have a significant positive impact on the physical health of the subjects,and then have a positive impact on the physical quality of the subjects.The vital capacity test was significantly improved,and the reaction quality of the students was improved,The endurance quality of students in the later stage has increased to a certain extent,and the abdominal muscle strength of students has significantly improved,that is,the relative strength of students has improved.The sensitive quality of students has increased to a certain extent,which is mainly reflected in the obvious shortening of the interval between continuous rope skipping after rope skipping is interrupted,and the improvement of reaction quality will also have a certain impact on the sensitive quality.(3)The control group can improve the physical health after routine sports skills and physical exercise,but compared with the data of the experimental group,the improvement range is smaller.Therefore,short rope skipping can have a more positive impact on the physical health of students compared with other sports.Suggestions:(1)carry out scientific physical exercise according to the students’ age,and choose the physical exercise method which more suitable for the students’ age.During rope skipping training,students should be taught to breathe reasonably in the process of sports and match the breathing with the form of sports.(2)When improving students’ physical health,we can improve students’ physical fitness through the continuous training of some sports skills,so as to improve students’ physical quality.However,fourth grade students are in the stage of obvious improvement of speed quality,which should be vigorously developed,but not too specialized.(3)Pay attention to students’ interest in sports and enhance the entertainment of sports.Teachers should set up personalized teaching courses and teach students according to their aptitude. |
