Introduction Engaging in physical activity has been proven to have health benefits, with a positive impact on sleep quality. While the timing of exercise plays a significant role in determining its effect on sleep, nighttime exercise still needs to be explored, especially in Saudi Arabia. This study assessed the effect of nighttime exercise on sleep quality among the general population in Riyadh, Saudi Arabia. Methods A cross-sectional study was conducted on people performing physical exercises in the gym, training, and walking places using a self-administered questionnaire evaluating exercising behaviors and sleep quality. Comparisons were performed using the Chi-square test and ANOVA, and p<0.05 was considered for significance. Results We enrolled 385 participants, among whom 53.8% were male, and 47.2% were female. The mean age was 28.2±7.85 years, and mostly aged 25-29 years (24.7%), followed by 20-24 years old (21.3%). Most had university degrees (61.3%) and were also employed (60%). Of all participants, the majority were overweight and obese (61.3%). Most (n=225) participants practiced vigorous physical exercise, and the mean Pittsburgh Sleep Quality Index (PSQI) global score was 7.37±3.49 points. Evening vigorous (r= 0.25, p=0.038) and moderate (r=0.30, p=0.025) physical exercise sessions lasting > 90 min had a significant positive correlation with poor sleep quality (high PSQL score). There was no statistically significant correlation between sleep quality and other variables (p>0.05). Conclusion This study found that participants had poor sleep quality, and lengthy, intense evening exercises had a negative effect on sleep. Incorporating regular exercise tailored to individual preferences and encouraging people to widen the time interval between exercise and bedtime could improve sleep quality.
引言 事实证明，进行体育活动对健康有益，对睡眠质量有积极影响。虽然运动时间在决定其对睡眠的影响方面起着重要作用，但夜间运动仍有待探索，尤其是在沙特阿拉伯。本研究评估了夜间运动对沙特阿拉伯利雅得普通人群睡眠质量的影响。
方法 采用自行填写的问卷对在健身房、训练场和步行场所进行体育锻炼的人群进行横断面研究，评估运动行为和睡眠质量。使用卡方检验和方差分析进行比较，p<0.05被认为具有统计学意义。
结果 我们招募了385名参与者，其中53.8%为男性，47.2%为女性。平均年龄为28.2±7.85岁，大多数年龄在25-29岁（24.7%），其次是20-24岁（21.3%）。大多数人拥有大学学位（61.3%）且有工作（60%）。所有参与者中，大多数超重和肥胖（61.3%）。大多数（n=225）参与者进行剧烈体育锻炼，匹兹堡睡眠质量指数（PSQI）全球平均得分为7.37±3.49分。持续>90分钟的夜间剧烈（r=0.25，p=0.038）和适度（r=0.30，p=0.025）体育锻炼与睡眠质量差（PSQL得分高）有显著正相关。睡眠质量与其他变量之间无统计学显著相关性（p>0.05）。
结论 本研究发现参与者睡眠质量较差，长时间、高强度的夜间锻炼对睡眠有负面影响。纳入根据个人喜好定制的定期锻炼并鼓励人们延长锻炼与就寝时间之间的时间间隔可以改善睡眠质量。
