An Experimental Study On The Coordination Ability Of 5-6 Year Old Children The Effect Of Physical Fitness Training Based On Dynamic System Theory

Motor coordination is the basis of human motor behavior and is of great importance to human movement development.Early childhood,as a sensitive period for the development of motor coordination,is a key link in the development of motor skills throughout a person’s life.Good motor coordination can help children improve motor control,promote the development of motor skills,and enhance their self-confidence.Poor motor coordination,on the other hand,can hinder children’s motor development and may cause psychological problems such as anxiety and depression;studies have shown that programs such as soccer,basketball and gymnastics can effectively improve young children’s coordination ability,but there is a general lack of systematic theoretical guidance.In this study,we designed a physical fitness training program based on dynamic system theory,combined with the characteristics of children’s movement development and experts’ suggestions,so as to explore the effects on coordination ability of 5-6-year-old children and provide effective training tools and theoretical guidance for the development of coordination ability of 5-6-year-old children.Methods: This study used the literature method,expert interview method and questionnaire method to design the content of physical fitness training based on dynamic system theory,and the experimental method was used to perform exercise intervention on the subjects.63 subjects were finally included by screening 81 subjects and randomly divided into experimental group(N=32)and control group(N=31),the experimental group used physical fitness training based on dynamic system theory for The experimental group used physical fitness training based on dynamic system theory for the intervention,and the control group used regular physical education classes,40 min per class,twice a week for 12 weeks.Finally,the non-parametric test was used to statistically analyze the test indexes of coordination ability before and after the experiment.Results:(1)In the comparison between the experimental group and the control group,all the indicators were better than the control group(P<0.01)except for the operant movement coordination(P>0.05);(2)The eight test indicators before and after the intervention in the experimental group were all very significantly different(P<0.01);(3)When comparing the performance of the control group before and after intervention,there were significant differences in four indexes except for hand-eye movement coordination,auditory limb movement coordination,posture-motion balance coordination,and operant movement coordination(P>0.05);(4)Boys in the experimental and control groups were better than girls in left and right upper limb movement coordination and voluntary movement coordination(P < 0.05),girls in the experimental group were better than boys in hand-eye movement coordination and postural balance movement coordination(P < 0.05);there were gender differences between boys and girls in individual indexes.Conclusions:(1)According to the dynamic system theory,the design of physical fitness training classes should be based on the changes of constraints(individual,environment and task)to teach and train,and gradually reach a stable state,and then change the training content and methods to develop to a higher level and break the original balance to reach a new stable state,so as to stimulate children’s interest in learning and improve the teaching and training effect.(2)The physical fitness training based on dynamic system theory has a better effect on the development of coordination ability of young children.The coordination ability of the experimental group was significantly improved;the coordination ability of the control group was also improved,but the progress was less than that of the experimental group.(3)There were significant differences in the development of coordination ability by gender.Boys were better than girls in the development of left and right upper limb movement coordination and autonomous movement coordination;girls were better than boys in the development of hand-eye movement coordination and postural balance movement coordination.
