The Creation Of Children's Aerobics And The Observation Of The Effect Of Improving Physical Fitness

Research Background:The healthy development of children 's constitution is an important symbol of the progress of social civilization in our country.School education work in the follow the "health first" guiding ideology in the process of children due to the pressure of school,parents spoil and bad eating habits and other reasons,leading to our children's physical health is not optimistic.Sports and health courses under the rhythm of the children's daily exercise is one of the main exercise,but the dynamic intensity is small,reducing the effectiveness of exercise.Therefore,this study is based on the physical and mental development characteristics of children,around the "play the main role of students" as the center,children take the initiative to participate in the classroom,to stimulate children's sports interest,to develop physical habits for the purpose of creating a set of 9-10 Children's children aerobics.Through the experimental test of this set of self-made children's aerobics and scientific rationality and rationality,and asked experts to exercise the value of self-exercise evaluation.Research methods:1.In this study,60 children aged 9-10 years old in Yongji Elementary School,Nankai District,Tianjin were selected as the subjects.The subjects were randomly divided into experimental group and control group.Children's aerobics classes were conducted for 10 weeks in the experimental group according to the children's aerobics.Children in the control group were given level 2 rhythmic gymnastics Learn.2.In order to test the scientific and rationality of the aerobics of children,this study was carried out before and after the experiment.All the subjects were tested for physical fitness index.Physical fitness indicators: height,weight,body weight,BMI,body fat%,skeletal muscle content;physical fitness indicators: seat flexion,standing long jump,reaction,eyes closed feet,6 meters to touch the ground 10 times;Vital capacity,cardiac function index,one skipping rope.Research result:1.Through the analysis and evaluation of relevant experts,this set of children's aerobics is a scientific,reasonable,style,sports load intensity is moderate,the difficulty is appropriate,to stimulate children's sports interest,improve children's physical health has some effectiveness.2.After the end of the experiment,the average vital capacity of the children in the experimental group increased by 236 ml,and the average score of one foot jump was increased by 15.3 and the cardiac function index decreased significantly.Suggesting that this set of self-made children's aerobics to improve children's physical function,promote the healthy development of physical health has a significant role.3.After the end of the experiment,the body shape of the experimental group showed a significant change,the average height of the experimental group increased0.96 cm,the average weight decreased 0.64 kg,the average BMI index decreased by1.27 kg / m2,the average increase of skeletal muscle 0.25 Kg,body fat% decreased by an average of 1.52%.It is suggested that the aerobics of children in this study can be used to improve the physical characteristics of children without affecting the normal growth and development of pupils.4.After the end of the experiment,the average flexion of the sitting group before and after the end of the experiment was 3.68 cm,the average standing time increased by 10.67 seconds,the average jump jump was 7.24 cm,the average time of the reaction was 5.4 seconds,Touch the ground 10 times the average reduction of 2.91 seconds.Indicating that this set of children aerobics created a scientific and rational,so that the experimental group of children's physical quality has been more obvious improvement.
