Creeping Motion Experimental Study On Morphology Of Primary Spinal

In recent years,the children' s spine problem is becoming more and more emergent,the study shows that the spianl morbidity rare of the pupils in the past 10 years has increased markedly,and the characteristics of spinal diseases are diversified.Whether physical activity in school can exert an preventive influence on the spinal problem of primary students becomes the key to the problem.The physical and chemical characteristics of children bone is less inorganic content,organic matter content,elastic and hardness small,hardness small spine easy deformation,elastic large spine problem is not easy to render.The investigation showed that the onset period of abnormal spinal column was generally concentrated in the 10-14-year-old children.It is particularly important to study the physical fitness of primary school students in spinal diseases.At present,the relevant scholars have more research on the crawl movement,and have obtained some research results,but the research direction is mainly for the elderly people's fitness,treatment,and the children's spine problem is less.Based on the above factors,through crawling training in the fourth Grade P.E.Class,the influence of the fourth grade students spine morphology is obtained,which provides the theoretical basis for improving the primary school physical Education teaching by introducing the spinal morphology and creeping training.This study carries on the theory and the practice discussion by means of literature,experimental method and mathematical statistics.The teaching experiment is carried out for 14 weeks in the study of 88 students in the fourth grade of Shimen Primary School in Shijiazhuang City.The curvature of the spine has heen tested respectively before and after the experiment(neck curvature and lumbar curvature),then,the study analyzes the data by means of SPSS20.0.Research results: experiment classes and control classes before the neck curvature curvature and the waist there was no significant difference(P>0.05),spinalform of 6 back State showed no significant difference(P>0.05).Experiment classes and control classes curvature in the neck,lumbar curvature normal back and spinal form of rickets,there was a significant difference(P<0.05).Classes in experimental curvature around the neck and lumbar curvature normal back and spinal form of rickets,there was a significant difference(P<0.05),saddle back,flat,straight back and lazy back showed there was no significant difference(P>0.05).Control group before and after the experiment curvature in the neck,lumbar curvature 6 back and spine morphology of State showed no significant difference(P>0.05).Research conclusion:1 Crawling movement can effectively promote the irregular spine shape of the primary to the normal spine.2 Crawling movement can promote the improvement of students' back shape in the fourth grade primary school,it is mainly performed in the improvement of pupils hunchback.
