Experimental Study On The Intervention Effect Of Table Tennis And Shuttleball On Myopia In Children And Adolescents

Research purpose: "myopia low age,accelerated,spread,severe" has become a prominent problem facing children’s eye health in China,physical exercise as a low-cost,non-invasive and effective intervention to prevent and alleviate the occurrence and development of myopia,is an important means of physical and health integration.In this study,the effects of 16-week table tennis near rubbing and far attack,shuttlecock(disc,turn,knock,and jump)on children’s eye vision,explored the effects of table tennis and shuttlecock on the prevention and control of myopia in children and adolescents,and provided scientific basis and practical exercise methods for sports to delay children’s vision problems.Research object and methods: in Dongguan stone elementary school 329-11 years old myopia(low myopia: 0.50 D myopia degree students-6.00D)children as the object,training is randomly divided into control group,table tennis,shuttlecock,table tennis shuttlecock group,each group of 8 people,for 16 weeks(3 times / weeks)of table tennis nearly rub far attack training and shuttlecock disc,turn,knock,jump training.The exercise intensity was controlled at 55%～70%HRmax,and the maximum heart rate range was about 160 beats / min.After training,blood lactate was controlled for 4 ～ 10 mmol/L,blood urea was controlled at 6～7.5mmol/L oxygen saturation within 98%～99%,and the average RPE fatigue index was from 12 to 15.Before and after the intervention,non-cycloplegic optometry was used to check the naked eye vision and corrected vision;cycloplegic optometry was used to check the eye visual indicators such as equivalent ball lens and eye axial length;and to check the restoration of normal state after pupil relaxation.Study results: I and four groups before and after the 16-week experiment:compared with before the experiment,the regulation sensitivity of T,S and S + S was significantly improved after the experiment,with significant difference(P <0.01).2.Exercise group and C after 16 weeks: Axle length: T + S eyes was significantly better than C,with significant difference(P <0.05);the adjustment sensitivity of T,S and T+ S was higher than C,S and T + S,with significant difference(P <0.01),and the T was slightly higher,with significant difference(p <0.05).3.Comparison between different exercise methods after 16 weeks of exercise intervention: 1.Compared with T and T + S,the corneal curvature of the left eye was significantly different(p <0.05);2.Axial length: left eye axis length between T and T + S increased significantly(p<0.01),right eye regulation sensitivity increased,S and T + S,left eye and right eye increased(p <0.05);3.Relative regulation: T and S increased significantly(p <0.05);4.The results of four groups of exercise intervention showed: C: T: S: T + S left eye improved regulation sensitivity,with significant difference(p <0.05);...
