The Effect Of The "Four Micros" Idea Research On The Sandbags Exercise Of The First Grade Pupils

With the rapid development of the society,people has paid more attention to health problems with the living standard being improved.Teenagers are the future of the motherland and they undertake the mission of realizing the great rejuvenation for our Chinese nation.However,according to the report of the national constitutional monitoring in recent years,the physical fitness of some students showed a downward trend.Students' academic performance and physical fitness can be compared to the wings of a bird and the double wheels of a car.At the same time,many parents pay more attention on children's study,they always neglect the cultivation of children's physical fitness.It is the key period for the children and adolescence to improve the physique in teenager stage.The first grade pupils enter the campus,full of freshness and curiosity.This stage is a critical period for the development of physical fitness and attention for pupils,such as flexibility,agility and coordination.Focused on the children's physical development and attention,and lay a good foundation for future learning and development.With the introduction of the new course standard and implementation,the development of curriculum resources has been fully reflected and a wide range of development.However,the physical education environment in some schools is still not optimistic.Physical exercise is often confined to physical education classes and everyday big class activities.Exercise less time,sports facilities and equipment shortage cannot meet the needs of the students exercise.In order to make full use of the school sports venues and time during class,we use the effective sports content and simple sports equipment to improve the physical fitness of pupils and develop their attention,the dissertation put forward the concept of "four micro" namely micro-site,micro-time,micro-content and micro-device.Its contents are selected micro-sports grounds of 1.6 and 3 square meters per capita in school.Within 6 and 8 minutes break,equipment is arranged for pupils to do small items sports in extracurricular physical training.Sandbag is a kind of sports equipment for children's games in our country,which has a high application value.Sandbag has various forms apart from the traditional lost sandbags,but also the sandbags cast,sandbags thrown and so on.It is entertaining and easy to operate,it can improve students' flexibility,reaction speed and move speed in entertainment.It can also cultivate students' consciousness to corporate and compete.Sandbags sports requires little in equipment and field.There is a larger space for development if carried out in primary and secondary students.The research is based on the research of literature,survey(including questionnaire and interviews),observation,experiment and mathematical statistics,we analyzed by theoretical knowledge and experimental data.In order to know the present situation of extracurricular physical training in Longteng primary school in Shijiazhuang,all teachers,students and parents before the experiment were surveyed,including 21 teachers,512 students and 512 parents.The result showed that the extracurricular physical exercise of pupils in Longteng was not optimistic,The shortage of equipment and facilities in school venues and the exercise time are relatively low.In the form of exercise content,the proportion of broadcast gymnastics is relatively high,and parents pay little attention to extracurricular sports activities.Teaching experiment was conducted before and after the experiment.Sixty-nine experimental specimens were tested for physical fitness(50-meter run,sit-forward flexion,one-minute jump rope)and attention test(Schulte test)to obtain the complete data.Data was analyzed using Excel2016 and SPSS20.0.Results:(1)There was no significant difference(P> 0.05)between physical fitness index and attention index before the experiment of the first grade and the control group in Longteng Primary School.(2)There was a significant difference(P <0.05)in attentiveness test between first-grade experimental class and control group of Longteng Primary School in Yuhua District,Shijiazhuang.There was a significant difference(P <0.05)between skipping in one minute and body flexion(P <0.05),and there was no significant difference in 50-meter running(P>0.05).(3)After the end of the experiment,it was observed that from the beginning of the experiment,the pupils chased after each other without any purpose,and now more elementary school students play sports games at a fixed place after class.Many other grades of primary school students imitate the contents of the exercises next to the venue,and someelementary school students bring sandbags from home and play together.This results in extra-curricular sports activities under the“four micro” concept,which can effectively activate the extracurricular physical training atmosphere in the school and imperceptibly affect more students to participate in the practice of sports.Conclusions:(1)The practice of punching bag under the concept of "four micro" has a positive effect on improving the physical quality and attention of first-grade pupils.(2)Under the concept of "four micro",the practice of first-grade primary school students' sandbags can activate the extra-curricular sports atmosphere in schools and promote more students to participate in physical exercises.
