Effect of Three Types of Ball Playing on Kinetic Visual Acuity for Children in Junior Grades / 中国康复理论与实践

ABSTRACT

Objective:To observe the effect of football, badminton and table tennis on kinetic visual acuity for children in grade one to three at elementary schools. Methods:From February to June, 2019, A total of 123 children aged seven to nine years from four elementary schools were divided into control group (n = 32), badminton group (n = 33), table tennis group (n = 30) and football group (n = 28). The children in the experimental groups accepted ball playing training for 16 weeks, while the control group did not attended any training course. The kinetic visual acuity was measured before and after training. Results:The kinetic visual acuity improved after training in the experimental groups (t > 2.196, P < 0.05), but not in the control group (t = 1.570, P > 0.05). The rates of improvement of kinetic visual acuity were football (26.82%), badminton (25.44%) and table tennis (19.21%). Conclusion:The ball games play a positive role in improving kinetic visual acuity for children in junior grades, especially the big ball games.
