摘　　要：目的探究闭锁性技能身体活动结合动态视觉任务对小学四年级近视儿童动态视敏度和静态视敏度的影响。方法2019年9月,选取苏州市带城实验小学四年级近视学生37例作为受试者。根据屈光系统调节工作原理,设计结合视觉切换任务的闭锁性技能身体活动干预方案,干预16周。干预前、干预8周后和干预16周后测量动态视敏度和静态视敏度。结果干预16周后,所有近视学生动态视敏度和静态视敏度均显著提高(F>15.933,P<0.001)。轻度、中度近视学生的动态视敏度和静态视敏度均改善(|t|>3.353,P<0.05),中度近视学生的静态视敏度改善幅度大于轻度近视学生(t=-2.830,P<0.01)。结论闭锁性技能身体活动结合动态视觉任务可改善四年级近视学生的视力水平。Objective To explore the effect of closed skills physical activity with additional dynamic visual task on dynamic visual acuity and static visual acuity for pupils with myopia at grade four at primary school.Methods In September,2019,37 pupils with myopia at grade four in Daicheng Experimental Primary School,Suzhou City were selected.In light of mechanism of refractive system,the intervention of closed-skilled physical activity with dynamic visual task was developed.They were intervened for 16 weeks.The dynamic visual acuity and static visual acuity were measured before intervention,and eight and 16 weeks after intervention.Results Both dynamic visual acuity and static visual acuity improved significantly in all the pupils with myopia after 16 weeks of intervention(F>15.933,P<0.001),both pupils with mild and moderate myopia(|t|>3.353,P<0.05).The static visual acuity was better in pupils with moderate myopic than with mild myopia(t=-2.830,P<0.01).Conclusion Closed skills physical activity with dynamic visual task could improve the visual acuity of puplis with myo‐pia at grade four at primary school.
