■视力对于足球运动员来说至关重要,影响决策和运动表现。尽管它在全球广受欢迎,足球缺乏对数字设备使用对高需求活动期间眼部症状影响的全面评估。
■为了获得有关足球运动员在高视觉需求活动中花费的时间的知识,与双眼视觉功能障碍相关的症状,以及它们与运动成绩的关系。
■2020年进行了一项针对葡萄牙足球运动员的在线调查,英格兰,西班牙,沙特阿拉伯。调查,分发超过5周,旨在收集大约5,000名足球运动员的数据。关于球员档案的信息,竞争水平,视力习惯,收集与双眼视力障碍相关的症状。收敛不足症状调查(CISS)采用5点Likert量表来指示每种症状的平均频率。由于非正态,采用非参数检验(p<0.05)。具体来说,Mann-WhitneyU,Kruskal-Wallis,卡方,适当时使用Spearman的等级相关检验。
■分析男性职业足球运动员(平均年龄:27.4±5.0岁,95%CI,26.7-28.1),结果发现,38.1%的球员被征召到国家队,6.9%的球员打了50场以上的比赛。自评上赛季的表现平均得分为6.5±2.1(95%CI,6.2-6.8)(在1至10的范围内)。所有玩家每天使用智能手机超过1小时,36.0%超过4小时。视觉症状,特别是与智能手机使用相关(35.5%),被观察到。关于CISS的分数,平均值为7.1±7.7(IC95%:6.6~8.8).CISS得分与自我感知的运动表现之间存在弱负相关(rho=-0.215,p=0.003)。使用处方镜片的足球运动员的CISS得分(11.9±10.4,95%CI,12.3-7.7)与非使用者(6.2±6.8,95%CI,7.8-5.7)相比(p<0.001)。
■这项研究表明,职业足球运动员从事高视觉需求的任务,尤其是在智能手机上。三分之一的玩家将智能手机的使用与眼部症状联系在一起。收敛功能不足症状调查表明,6.3%表现出双眼视觉功能障碍症状。那些眼部症状较少的人认为他们比同龄人有更好的运动表现。
UNASSIGNED: Vision is crucial for football players, impacting decision-making and athletic performance. Despite its global popularity, football lacks comprehensive evaluations of the impact of digital device use on ocular symptoms during high-demand activities.
UNASSIGNED: To gain knowledge about the time spent by football players in high visual demand activities, the symptoms associated with binocular vision dysfunction, and their relationship with sports performance.
UNASSIGNED: A cross-sectional observational study was conducted in 2020 using an online survey targeting football players from Portugal, England, Spain, and Saudi Arabia. The survey, distributed over 5 weeks, aimed to collect data from approximately 5,000 football players. Information on player profiles, competitive levels, vision habits, and symptoms related to binocular vision dysfunctions was collected. The Convergence Insufficiency Symptom Survey (CISS) employed a 5-point Likert scale to indicate the average frequency of each symptom. Due to non-normality, non-parametric tests were used (p < 0.05). Specifically, Mann-Whitney U, Kruskal-Wallis, Chi-square, and Spearman\'s rank correlation tests were used as appropriate.
UNASSIGNED: Analyzing male professional football players (mean age: 27.4 ± 5.0 years, 95% CI, 26.7-28.1), it was found that 38.1% of the players had been called up to the national team and 6.9% had played over 50 games. Self-rated last season\'s performance had a mean score of 6.5 ± 2.1 (95% CI, 6.2-6.8)(on a scale of 1 to 10). Smartphone use exceeded 1 h daily for all players, with 36.0% surpassing 4 h. Visual symptoms, notably associated with smartphone use (35.5%), were observed. Regarding the CISS score, the mean was 7.1 ± 7.7 (IC95%: 6.6 to 8.8). A weak negative correlation (rho = -0.215, p = 0.003) emerged between CISS scores and self-perceived sports performance. Football players using prescription lenses had significantly higher CISS scores (11.9 ± 10.4, 95% CI, 12.3-7.7) compared to non-users (6.2 ± 6.8, 95% CI, 7.8-5.7) (p < 0.001).
UNASSIGNED: This study reveals that professional football players engage in high visual demand tasks, notably on smartphones. One-third of the players link smartphone use to ocular symptoms. The Convergence Insufficiency Symptoms Survey indicates that 6.3% exhibit binocular vision dysfunction symptoms. Those with fewer ocular symptoms perceive that they have better sports performance than their counterparts.
