Effects of orienteering exercises on myopia prevention and control of primary school students / 中国学校卫生

ABSTRACT

Objective@#To analyze the eye gaze pattern during the orienteering exercise and effects of orienteering exercises on myopia prevention and control in primary school students, so as to provide reference for the effective prevention and control of myopia.@*Methods@#Visual acuity screening was conducted on fifth grade students aged 10-11 years old in Shaanxi Normal University Primary School, and 120 primary school students with abnormal visual acuity were selected and randomly divided into experimental group ( n =60) and control group ( n =60). The experimental group practiced orienteering cross country program on the basis of the control group, and compared the differences in myopia improvement between the two groups through the characteristics of eye changes tested by ETG spectacle type oculomotor.@*Results@#The differences between the experimental group and the control group in naked eye visual acuity, refraction and visual fatigue before the intervention were not statistically significant ( t=0.13, 1.94, 0.70, P > 0.05); after ten weeks of intervention, the naked eye visual acuity, refraction and visual fatigue of the experimental group were better than those of the control group, and the differences were statistically significant ( t=11.28, 15.03, -247.01, P <0.05). During the process of map recognition and scene recognition, the differences in fixation time, number, frequency and saccade distance of the experimental group were statistically significant ( t=-13.62, -7.83, 4.82, 7.15, P <0.05); the students in the experimental group showed alternate eye gaze characteristics in the process of map recognition and scene recognition.@*Conclusion@#During orienteering exercises, map recognition and real scene recognition mobilized eye following, sweeping, gaze, focus and alternate visual tracking, which have an improved effect on myopia prevention and control in primary school students.
