体育教学中防控近视的睫状肌训练频次研究

Study on the Frequency of Ciliary Muscle Training for the Prevention and Control of Myopia in Physical Education

目的:分析比较体育教学中低频15次、中频30次,以及高频60次的睫状肌训练对八年级学生视力所产生的不同影响。方法:在体育课中分别对3个实验组进行低频15次、中频30次、高频60次睫状肌训练,测量并分析干预前后实验组与对照组学生的裸眼远视力与动态视力。结果:(1)低频15次组学生的裸眼远视力与动态视力无显著性变化;(2)中频30次组学生的动态视力在干预后显著上升,裸眼远视力的提高无显著性差异;(3)高频60次组学生的裸眼远视力与动态视力在干预后均显著上升;(4)对照组学生的裸眼远视力与动态视力呈下降趋势。结论:体育教学中嵌入不同频次的睫状肌训练对八年级学生视力水平的影响不同,其中60次高频训练对裸眼远视力改善效果最佳,30次中频训练对动态视力的改善效果更好,15次低频训练能够基本维持学生裸眼远视力和动态视力的原有水平。在体育教学中进行睫状肌训练能够有效延缓近视的发展速度,促进学生视力水平发展。

Objective:In order to analyze and compare the different effects of low frequency 15,intermediate frequency 30 and high frequency 60 times of ciliary muscle training on the vision of the eighth graders in physical education.Methods:In the physical education class,the low-frequency 15,intermediate frequency 30 and high-frequency 60 times of ciliary muscle trainings were carried out in the three experimental groups,and the naked-eye far vision and dynamic vision of the students in the experimental groups and the control group were measured and analyzed before and after the intervention.Results:(1)There was no significant change in naked-eye far vision and dynamic vision of students in the low-frequency 15-time group;(2)there was a significant increase in dynamic vision of students in the intermediate frequency 30-time group after intervention,but no significant difference in the improvement of naked-eye far vision;(3)naked-eye far vision and dynamic vision in the high-frequency 60-time group increased significantly;(4)naked-eye far vision and dynamic vision showed a downward trend among students in the control group.Conclusion:Ciliary muscle training with different frequencies in physical education has different effects on the visual level of the eighth grade students,of which 60-time high-frequency trainings have the best effect on the improvement of naked-eye far vision,and 30-time intermediate frequency trainings have better effects on the improvement of dynamic vision.While 15-time low-frequency training sessions can basically maintain the original level of naked-eye long-distance vision and dynamic vision.Therefore,ciliary muscle training in physical education can effectively delay the development of myopia and promote the development of students'vision level.
