Experimental Research On The Effect Of Latin Aerobics On The Physical Constitution Of Fourth Grade Pupils

The healthy development of elementary school physique is very important to the progress of our social civilization.But it is found that there are some problems such as the increase of obesity rate and myopia rate.Latina aerobics is a kind of aerobic exercise combining Latin dance elements with aerobics.It is also a kind of physical activity that can not only stimulate strength but also improve learning interest.A large number of studies have shown that appropriate physical activity can promote the physical health of children and adolescents.However,there are few studies on the application of Latina aerobics in elementary school physical intervention means and methods.Therefore,in this paper,the independent creation of Latin aerobics exercise on the primary school physique exercise intervention research has a certain theoretical reference and practical significance.In this study,the fourth grade students were taken as the experimental objects,and a set of aerobics Latin exercises and training program created by myself and approved by experts was used.An 8-week experiment was carried out to explore the effect of aerobics Latin exercises on the physical fitness level of primary school students.It aims to innovate the methods and means of physical exercise for primary school students and enrich the content of physical exercise in school.Through literature review method,expert interview method,questionnaire method,experiment method,mathematical statistics method and logical analysis method,and reference to a large number of video materials about Latin aerobics,develop a set of scientific and reasonable experimental program of Latin aerobics.A total of 35 students(male: 15,female: 20)from Class 4(6)were selected as the control group,and 35 students(male: 15,female: 20)from class 4(7)were selected as the intervention group.The intervention group received Latina aerobics in 3 classes per week,40 minutes per class,for 8 weeks,a total of 24 classes;The control group exercised according to the physical education syllabus of the school.Before and after the intervention,all subjects were tested by the national physical health standard index,and the experimental data were statistically analyzed.Results: 1.After the experiment,the body shape,body function and physical fitness of the intervention group and the control group showed that the height index of the intervention group had no significant effect(p>0.05),the body weight index had a significant reduction effect(p<0.01),and the other body mass index had a significant improvement effect(p<0.01);In the control group,height and body weight indexes were not significant(p>0.05),and other body mass indexes were significantly improved(p<0.01).The improvement effects of body weight,vital capacity,seated flexion and other indicators in the intervention group were higher than those in the control group,and the improvement effects of other indicators were similar.2.After the experiment,through the feedback data of primary school students’ liking for Latin aerobics,satisfaction with the design of the complete set of self-compiled Latin aerobics and the recognition of the training process,82.9%primary school students like Latin aerobics exercise project,and 88.6% students are willing to continue to learn Latin aerobics in physical education class.80% of the students are satisfied with the choreography and design of the Latin aerobics and the selection of Latin music;85.7% of the students can accept the exercise intensity of the training process,and 85.7% of the students think the Latin aerobics training process is rich and interesting,91.4% of the students feel happy when practicing.Conclusion:1.The results of continuous 8-week exercise experiment show that,without affecting the normal growth and development of primary school students,the Latin aerobics training can help students shape and reduce fat,effectively improve the cardiopulmonary function and physical fitness,and has a better effect than the conventional physical education in weight reduction,lung capacity and flexibility.It shows that the independent creation of Latin aerobics has a positive effect on the physical fitness level of pupils.2.The effect after the experimental application of aerobics Latin exercises assessed by experts show that the teaching content design of aerobics Latin exercises is targeted,operable and interesting,and the exercise load intensity is scientific and reasonable,with the characteristics of aerobic training,which has been recognized by the experts,indicating that the design and training methods of this routine are scientific and feasible.3.The feedback results of primary school students’ liking for aerobics Latin exercises show that this routine is loved by most primary school students,and they are willing to continue to learn aerobics Latin exercises in physical education class,indicating that aerobics Latin exercises can stimulate primary school students’ interest in class and cultivate their lifelong hobby of participating in physical exercise.
