Physical exercise can improve sleep quality in the general population. Understanding the negative impact of poor sleep quality on multiple domains of functioning among persons with schizophrenia is a new frontier of exploration. It is also imperative to investigate non-pharmacologic methods to improve sleep quality as these approaches may not carry the side effect burdens associated with medication.
We examined the relationship between regular physical exercise and sleep quality among participants in an intervention consisting of both cognitive training and exercise.
Participants (N = 48) were schizophrenia patients who had a first psychotic episode within two years of study entry. Participants received 4 h/week of internet-based cognitive training and an aerobic exercise program over a 6-month period. Sleep was assessed with the Pittsburgh Sleep Quality Index at baseline and six months later.
During the 3 months prior to the 6-month follow-up sleep assessment, participants completed an average of 12.6 group exercise sessions and an average of 12.9 individual at-home exercise sessions. A significant relationship between the number of exercise sessions and global sleep quality was seen at month six, r = -0.44, df = 39, < 0.01. Group exercise frequency was also associated with improvement in global sleep quality over the six-month intervention, t(34) = -2.84, = 0.008.
We demonstrated that a group of young adults with schizophrenia can be engaged in a regular exercise program, even during the tumultuous early course of the disorder. The number of exercise sessions in which they participated was associated with better sleep quality at six months and pre-postintervention improvement in sleep quality.
Improved sleep quality appears to be a benefit of regular exercise among individuals with serious mental illness.
体育锻炼可改善普通人群的睡眠质量。了解睡眠质量差对精神分裂症患者多方面功能的负面影响是一个新的探索领域。研究非药物方法来改善睡眠质量也很有必要，因为这些方法可能不会带来与药物相关的副作用负担。
我们研究了在一项包括认知训练和锻炼的干预措施中，规律体育锻炼与参与者睡眠质量之间的关系。
参与者（N = 48）为在研究入组两年内首次出现精神病发作的精神分裂症患者。参与者在6个月的时间里接受每周4小时的基于互联网的认知训练和一项有氧运动计划。在基线和6个月后使用匹兹堡睡眠质量指数评估睡眠情况。
在6个月随访睡眠评估前的3个月里，参与者平均完成了12.6次团体锻炼课程和12.9次个人在家锻炼课程。在第6个月时，锻炼课程次数与整体睡眠质量之间存在显著关系，r = -0.44，自由度 = 39，P < 0.01。在为期6个月的干预期间，团体锻炼频率也与整体睡眠质量的改善相关，t(34) = -2.84，P = 0.008。
我们证明了一组患有精神分裂症的年轻人即使在疾病动荡的早期阶段也能参与规律的锻炼计划。他们参与的锻炼课程次数与6个月时更好的睡眠质量以及干预前后睡眠质量的改善相关。
改善睡眠质量似乎是重度精神疾病患者规律锻炼的一个益处。
