Abstract:

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 myopia at grade four at primary school.
