RESUMEN
Objectives To explore the effects of visual tasks added in physical activities on kinetic and static visual acuity for 6-9 years old children.Methods Children's visual function and seeing activity were analyzed and four kinds of physical activities with visual tasks were designed. From June to August, 2018, 38 pupils from a sports summer camp aged 6 to 9 years with normal vision participated in the eight-week training. Their kinetic and static visual acuity was measured before, four weeks, and eight weeks after training.Results Both kinetic and static visual acuity improved after training (F＞ 24.368, P ＜ 0.001), and the binocular static visual acuity improved more in the boys than in the girls (t＞ 2.161, P ＜ 0.05). There was a moderate positive correlation among kinetic and static visual acuity (r＞ 0.424, P ＜ 0.01).Conclusion Physical activities with visual tasks are beneficial for kinetic and static visual acuity for children aged 6-9 years, which may be an approach to promote vision health.
