Effect Of Diurnal Rhythm On Balance Ability Of 11-year-old School-age Children

Objective: The physical health of young children has always been the focus of our country,their healthy growth is related to the future of our country.With the development of science and technology,developed means of science and technology become dominant,so that physical activity is gradually reduced,and then physical fitness is reduced.Balance ability belongs to one kind of physical quality and is also one of the important physiological functions of human body.It is a kind of ability that the human body can keep the body posture relatively stable under the condition of resisting to destroy the external force of balance.Good balance not only enables young children to thrive,enhance their sports ability,but also reduce the fall rate of the elderly,and protect daily life.Through literature research,it is found that the athletes and the elderly show different balance ability at different times.Circadian rhythms,especially circadian rhythms,have an impact on the body's ability to balance.In order to study the effect of daily rhythm on the balance ability of 11-year-old school-age children,this paper chooses 11-year-old school-age children whose balance ability development tends to be stable to test the different time-balance ability or not,and discusses the effect of daily rhythm on the balance ability of 11-year-old school-age children.To provide the choice basis for the development of children's balance ability in the future,and to provide accurate evaluation basis for physique monitoring,and to further optimize the performance evaluation.Methods: In this paper,11-year-old school-age children were studied by means of literature,experiment and mathematical statistics.We measured the performance of11-year-old school-age children at different times(8:00 and 15:00)with closed eyes and one-foot standing,star-shaped stretching balance,and then added development balance training to the physical education class of the subjects.A total of 12 weeks was carried out(see the main text for the design of the experiment).The static and dynamic balance ability was measured at different time(8:00 and 15:00).The effect of diurnal rhythm on juvenile balance ability was studied by comparing and analyzing the test indexes before and after the experiment.Results: 1.The static balance ability of 11-year-old school-age children before the experiment was not affected by circadian rhythm,and there was no significant difference between closed eyes and one-foot standing in the morning and afternoon(p > 0.05).Thedynamic balance ability of 11-year-old school-age children was affected by circadian rhythm,and showed significant difference(p < 0.01).The circadian rhythm had significant difference in the anterior and outer direction,the posterior direction and the inner direction of the left leg(p < 0.01).On the whole,the dynamic balance ability in the morning was higher than that in the afternoon.The circadian rhythm had significant difference in the forward direction,the outer direction and the forward and inner direction under the support of the right foot(p <0.01).The dynamic balance ability in the morning was higher than that in the afternoon.2.There was no significant difference in the ability of dynamic and static balance between different genders at different time before the experiment(p > 0.05).After the development balance training was added to the physical education class,there was significant difference in the dynamic and static balance ability of 11-year-old school-age children(p < 0.05).4.After the intervention,there was significant difference in standing with closed eyes and one foot in the morning and afternoon(p < 0.01),and the dynamic balance ability of 11-year-old school-age children was affected by circadian rhythm(p < 0.05).The dynamic balance ability in the morning was higher than that in the afternoon(p < 0.05),and the dynamic balance ability in the morning was higher than that in the afternoon(p < 0.05),and the dynamic balance ability in the morning was higher than that in the afternoon(p < 0.05),and the dynamic balance ability in the morning was higher than that in the afternoon(p < 0.01).The circadian rhythm had significant difference in the forward direction under the support of the right foot(p < 0.01),and there was significant difference in the anterior and outer direction,the posterior direction and the inner direction(p < 0.05).The dynamic balance ability in the morning is greater than that in the afternoon.Conclusion: 1.The circadian rhythm has a significant effect on the dynamic balance ability of 11-year-old school-age children,but has no effect on the static balance ability.2.The effect of circadian rhythm on the balance ability of 11-year-old children of different sexes was not significant,and there was no difference between male and female students.3 exercise intervention could increase the balance ability of 11-year-old children,but its internal law was not disturbed.The ability to maintain dynamic balance in the morning is greater than that in the afternoon.4.Balance can be improved by training.12-week balance training can effectively improve the balance ability of 11-year-old children.
