| Research basis:In the last year,the decline in physical fitness and the weakening of athletic ability of children and adolescents in the world have called for the reform of track and field sports.In the same time,my country to reform the school'sport,the time and content of track and field courses have undergone major changes.They are sensitive periods for the development of various physical qualities.Faced with the bottleneck faced by our country's adolescents'physique and in development of my country track and field in school sports,how to link the physical health of young people with track and field sports.Athletics and school sports are crucial.Significance of research:This study comprehensively studied the impact of the Children's Interesting Track and Field Teaching Program on the physical functions of(10-12)-year-old primary school students,and compared and analyzed the indicators under the traditional track and field teaching program to explore children's interest in track and field.The characteristics and laws of the influence of primary school students on the physical mechanism provide reference for the further promotion of children's interest in track and field and improvement of track and field development in primary school sports,improvement of primary school students'physical functions,and to reforming primary education courses in elementary school,especially for track and especial on athletics courses.Research facilities and methods:on the experiment,96 students from five natural classes in the fifth grade of experimental primary school of Daxing New District,randomly selected by Shanxi Normal University.Through the test of various indicators before the experiment,students with excessive data discrepancies were excluded.To is used literature review methods,expert interview,experimental methods,statistical methods,and comparative analysis methods,through testing,and then analyze the size of the body(height,weight,BIM)and the function of the movement of boys and girls in primary and secondary schools before and after the experiment.Respiratory to sensory and neurological function,balance function and other indicators of change.Research results:(1)Changes in circulatory function of the experimental group and the control group before and after the experiment,the quiet heart rate of the male and female subjects in the control group,the instantaneous heart rate after exercise,the time to return to a quiet heart rate,systolic blood pressure,diastolic blood pressure immediately after exercise,and exercise There was no significant difference in immediate diastolic pressure(P>0.05),and there was a significant difference before and after the step index experiment(P<0.05).The boys'exercise rate immediately after exercise,the time to return to quiet heart rate,and before and after step index experiment(P<0.01)There was a very significant difference.Quiet heart rate,systolic blood pressure,diastolic blood pressure,immediate systolic blood pressure after exercise,immediately before and after exercise diastolic pressure test(P>0.05),there was no significant difference,Immediately after the exercise of girls'heart rate after exercise(P<0.05),there was no significant difference,immediately after the exercise of girls'heart rate after exercise(P<0.05)There was a significant difference between the time of recovery to quiet heart rate and before and after step index experiment(P<0.01).(2)Before and after the experiment,the changes of respiratory function in the experimental group and the control group,the vital capacity,the time vital capacity and the maximum ventilation of the control male and female students had no significant changes before and after the experiment(p>0.05);the vital capacity and time of the male volunteers in the experimental group(P<0.05)There was a significant change in the maximum ventilation before and after the experiment(P>0.05).There was no significant change before and after the lung capacity test(P<0.05).The time before and after the vital capacity test(P<0.01)The change was very significant,and there was no significant change in maximum ventilation before and after the experiment(P>0.05).(3)Changes in sensory and neurological function in the experimental group and the control group before and after the experiment.There was no significant difference in the perceived jump distance between the control group and the male and female students before and after the simple reaction(p>0.05).There was a significant difference in the perceived jump distance between boys and girls in the experimental group before and after the test(P<0.01),there was a significant difference before and after the experiment(P<0.05)in the selection response,and the perceived jump distance of the girls was tested and there was a very significant difference before and after the experiment(P<0.01).(4)Differences in balance function between the experimental group and the control group before and after the experiment.There was no significant difference in male and female closed eyes of control group before and after on test(p>0.05).On male eyes to experimental group were closed.There was a significant difference before and after the experiment(P<0.05)in the test of cross-over balance(P<0.05).Before and after the experiment of the closed eyes of the control group and the experimental group(p>0.05).There was no significant difference between the two groups before and after the experiment(P<0.05).Research conclusions:(1)"Children's Fun Track and Field"teaching has no significant effect on most of the circulation functions of children's bodies(10-12),but it has a significant improvement on the circulation functions of some body machines.The main performance in the exercise immediately after the heart rate,after the movement to quiet heart rate time,step index and other related indicators have a significant effect.(2)"Children interesting track and field"teaching can improve(10-12)children's partial respiratory function,the specific performance of lung capacity,time lung capacity indicators have a significant effect,and compared with the regular physical education has a certain advantage.(3)There were significant differences in the perceived jump index and the selective response after the experiment,which showed that international children's fun track and field activities could improve the sensory and neural functions of children(10-12).(4)Through"children interesting track and field"exercise can effectively improve(10-12)children's physical balance ability,improve the effective force order of children's leg strength. |
