体育运动对视敏度的影响
摘 要：视敏度即视力，包括静态视敏度和动态视敏度，在日常生活和运动中起到重要作用。如何预防和降低青少年近视率已引起了国家各层面的重视，其中，加强体育锻炼，保证学生体育活动时间成为重要对策之一。目前国内外的相关和干预研究结果发现，经常参加体育运动的个体视敏度较好，且适度的运动训练能够改善个体的视敏度，但同时改善效果會受到个体差异和实验装置的影响。体育运动能够改善视敏度可能是由于晶状体和睫状肌不断的运动调节，提高了个体追踪目标的能力，从而缓解视疲劳，降低近视率。今后该领域应进一步关注静态和动态视敏度的结合、其他影响因素的控制、运动训练效果的保持效应以及认知神经机制等问题。

Abstract：Visual Acuity（sight）， including Static Visual Acuity and Dynamic Visual Acuity， plays an important role in our daily life. How to prevent and reduce the myopia rate of adolescents has attracted the attention of the country. One of the important measures is to strengthen physical exercise and ensure students" time of sports. The studies of correlation and intervention have found that the better visual acuity for those who exercise regularly， and the moderate sports training can improve individual"s visual acuity， which would be influenced by individual"s difference and laboratory equipment. The reason that physical exercise can improve visual acuity may be due to the continuous movement of the lens and ciliary muscles， which improves the ability of individuals to track targets， thereby relieving individual visual fatigue and reducing myopia. Future research should focus on the combine of Static Visual Acuity and Dynamic Visual Acuity， control of other influencing factors， the retention time of sports tr...
