An Experimental Study On The Effect Of Synchronized Rope Skipping On The Body Composition And Mood Of High School Girls

Physical education is an important part of school physical education,and physical education activities have an irreplaceable role in improving the physical and mental health of students.High school students are in the mature period of the development of secondary sexual characteristics.They pay more attention to the external beauty of their body shape,especially the girls in high school.They have less time to participate in sports activities and lack of interest.Long-term bad sitting posture leads to body deformation,which seriously affects their physical and mental health.Therefore,it is very important to choose a suitable and interesting sport.As a new sport,synchronized rope skipping is deeply loved by the majority of people.It is a sport that integrates fitness,entertainment,interest,appreciation,competitiveness and culture.It plays an important role in the aspects of pleasing the body and mind,cultivating students' interest in learning and relieving psychological pressure.Through the research methods of literature,investigation,experiment and mathematical statistics,this study takes the girls in grade two of Qufu No.1 middle school as the experimental object,and takes the influence of rope skipping on the body composition and mood of girls in high school as the research object.60 girls are divided into experimental group and 30 girls are divided into 12 weeks of rope skipping teaching intervention,control group and 30 girls are divided into regular physical education teaching Statistics and analysis of the data obtained.Through exploring the influence of synchronized rope skipping on the body composition and mood of high school girls,we can provide reference for the smooth development of synchronized rope skipping in high school,so as to achieve the real experimental purpose and promote the overall development of students' physical and mental health.Experimental results:1 Before the experiment,there was no significant difference between the experimental group and the control group in the body composition and mood dimensions,with homogeneity.2 Before and after the experiment,it can be seen from the t-test that there are verysignificant differences in body composition,body weight,BMI index and body water in the experimental group,and significant differences in the indexes of fat free body weight,muscle mass and waist to hip ratio;only the fat free body weight in the control group shows significant differences,and other indexes have no significant changes.3 Before and after the experiment,there were very significant differences in all dimensions of mood state of senior high school girls in the experimental group;in the control group,there were very significant differences in the dimensions of tension,energy,self-related,TMD total score,and there were significant differences in the dimensions of anger and fatigue.4 After the experiment,the body composition of the experimental group was better than that of the control group in terms of body weight,muscle mass and body water,with significant differences.5 After the experiment,the scores of mood in the experimental group were higher than those in the control group,and there were significant differences in anger,depression,panic,energy and TMD.Conclusion:1 Experiments show that the effect of synchronized rope skipping on the body composition of high school girls is very significant.In the aspect of reasonable control of the time and intensity of high school girls' sports,their weight,fat free weight,muscle mass,waist hip ratio,and body water are significantly reduced.2 After the experiment,all dimensions of mood(tension,anger,fatigue,depression,energy,panic,and self-related)in the experimental group showed different degrees of improvement,especially in the dimensions of anger,depression,energy,panic.3 The experiment shows that the effect of synchronized rope skipping on the body composition and mood of girls in senior high school is more significant.Therefore,synchronized rope skipping is a sports event suitable for girls in senior high school,which is of great significance to the reform of physical education curriculum and the development of synchronized rope skipping in China.
