An Experimental Study On The Development Of The Flexible Quality Of 7-8 Years Old Children

The rapid development of human flexibility is in the child stage.From the perspective of human physiology: children at a critical stage of flexibility of development,if the flexibility level and flexibility exercises will be larger,to promote the development of children's physical health,and children with heart and muscle development is not complete,should not add too much physical strength and endurance practice in practice,so in childhood more flexible quality training is the most appropriate.In this paper,two grade students in the primary school affiliated to China University of Petroleum were selected as the subjects of the experiment.Class 5 and class 6 were experimental group,class 7 and class 8 were control group.The students of grade two in the primary school affiliated to China University of Petroleum were randomly selected for the experiment for a period of 16 weeks.First a test before the experiment,the experiment after a general test,testing of the basic indicators of the national system of the second grade pupils health test indicators(50 meters,side throw sandbags,400 meter run,sit and reach,10 meter running,10 meters Liu Lianqiu),16 weeks after the collection of test data after the experiment,and the experimental group and the control group,the second grade students before and after the experiment of the physical quality index(speed,strength,endurance,flexibility,agility,balance)to summarize,analyze and summarize,explore the importance of flexibility exercises for 7-8 years old children's physical quality development.The main conclusions of the study are as follows: The development of the flexibility of the 7-8 years old children.Flexible quality training for 7-8 years old children have a greater role in promoting the development of speed quality.Children's flexibility exercises have a great effect on the development of children's 7-8.Flexibility exercises can promote the development of 7-8 years old children.Flexibility exercises for children aged 7-8 years in power,endurance and other quality development effect is not prominent,the main reason is that this period is not in a sensitive period of growth for the growth of children's physical quality,strength and endurance during this period the quality of slow.
