Study On The Influence Of Cha Cha Dance On Physical Health And Sports Pleasure Of Senior High School Students

Research objective: In the new era,the Party and the state attach great importance to the physical and mental health development of teenagers,and have issued a number of policies to improve the physical health level of teenagers.Driven by the policy,the physical health status of teenagers has been improved to some extent,but it still needs to be further improved.In this context,schools,as the main position of youth activities,should actively seek for interesting and diversified ways of sports and exercise to attract teenagers to actively participate in sports,and effectively improve the physical health level of teenagers through physical exercise.The cha-cha dance is lively and interesting.Introduce it into the campus can not only stimulate students’ interest in participating in physical exercise,but also promote the diversified development of the middle school curriculum system.Based on this,on the basis of the teaching intervention of cha-cha dance for senior high school students,this study understands the role of developing and promoting cha-cha dance in senior high school students,so as to provide reference for Latin dance to be incorporated into the middle school curriculum system.Research methods: This study adopts the methods of literature,experiment,questionnaire and mathematical statistics to randomly divide 185 senior one students of Qinxian Middle School in Shanxi Province into the experimental group(94 in total)and the control group(91 in total).The experimental group has 16 weeks of Cha-cha dance teaching,and the control group has 16 weeks of regular physical education teaching.Compare and analyze the test data and changes of the physical health indicators and sports pleasure of the two groups of subjects before and after the experiment,and explore the impact of cha-cha dance on the physical health and sports pleasure of high school students.Finding:(1)In terms of body morphology,the body weight,BMI,waist circumference,hip circumference,thigh circumference and abdominal skinfold thickness were significantly improved in the experimental group(P <0.05),with no significant change in the skinfold thickness in the upper arm and height(P> 0.05).The T test of independent samples after the experiment showed that the waist circumference,thigh circumference and abdominal skin fold thickness of the experimental group were significantly better than those of the control group(P<0.05).(2)In terms of physical function,the vital capacity of the male and female experimental groups was significantly improved(P <0.05),and the quiet pulse rate was significantly decreased(P <0.05).The T test of independent samples after the experiment showed that there was no significant difference in vital capacity and resting pulse rate between the experimental group and the control group.(3)In terms of physical quality,the performance of 800 / 1000 m,sitting forward bending,standing long jump,sit-ups,standing with eyes closed and 4 round-trip running of 10 meters in the experimental group were significantly improved(P <0.05),and the performance of 50 m and pull-up movement did not change significantly(P>0.05).After the experiment,the independent sample T test showed that the boys in the experimental group were significantly better than the boys in the control group in the indicators of 1000 m,sitting forward flexion,and standing on one foot with eyes closed(P<0.05).Two groups of girls bend forward in the sitting position,standing long jump,sit-ups,standing on one leg with eyes closed and 10 meters × The round-trip running indexes were significantly better than those of the control group(P<0.05).(4)After the experiment,the sports pleasure of male and female students was significantly improved(P<0.05).The T test of independent samples after the experiment showed that the indexes of sports pleasure in the experimental group were significantly better than those in the control group(P<0.05).Research conclusion:(1)Cha-cha dance can significantly have an effect on the improvement of the body shape of high school students.After the experiment,students’ body weight,BMI index,body circumference and abdominal skinfold thickness indexes were significantly optimized,but the improvement of the skinfold thickness index of the upper arm was not as obvious as that of conventional physical education.(2)The cha-cha dance can improve the physical function of high school students and achieve significant results.After the experiment,the students’ vital capacity is significantly improved,and the quiet heart rate is correspondingly reduced.The improvement effect of the two indicators is better than that of the conventional physical education class.(3)Cha-cha dance has a positive effect on the endurance,flexibility,balance,sensitivity,lower limb and lumbar and abdominal muscle strength of high school students,but it has no obvious effect on the improvement of students’ speed quality and upper limb muscle strength.(4)Cha-cha dance is very interesting.It can also take into account gender differences,better stimulate students’ enthusiasm for learning,and has great effect on improving students’ sense of sports pleasure when participating in sports activities.(5)There is a correlation between some physical health indicators and sports pleasure of high school students after Cha-cha dance intervention.The improvement of sports pleasure can promote students to actively participate in cha-cha dance practice and maximize the fitness value of the project.
