Home base recordings of motor activity during bedtime, and of subjective sleep parameters, were obtained from air crew members before and after the following routes with multiple flight segments: (1) south-north (SN) across 1 time zone; (2) west-east (WE) across 17 time zones; (3) east-west (EW) across 7 time zones. For the EW route, recordings were also obtained during layover. Only after return from the EW route was bedtime motor activity (measured by a wrist-worn ambulatory monitor) enhanced, was the percentage of bedtime immobility periods reduced, and were frequency and duration of self-assessed waking after sleep onset increased. The subjects rated their sleep as less quiet and felt less rested than during baseline. The various parameters gradually reverted toward baseline during the first 4 days at home. Although sleep showed only minor impairments during the EW route, the subjective jet-lag score was high during layover and after return to home base. Ambulatory activity monitoring is a useful method for assessing sleep quality after long-haul flights.
在执行以下包含多个航段的航线前后，从机组人员处获取了就寝时间的运动活动及主观睡眠参数的居家记录：(1) 南北向（SN）跨越1个时区；(2) 西东向（WE）跨越17个时区；(3) 东西向（EW）跨越7个时区。对于EW航线，在中途停留期间也进行了记录。仅在从EW航线返回后，就寝时间的运动活动（通过佩戴在手腕上的动态监测仪测量）增强，就寝时静止期的百分比降低，且睡眠开始后自我评估的觉醒频率和持续时间增加。受试者将他们的睡眠评价为不如基线时安静，且感觉休息程度不如基线时。在家的头4天里，各项参数逐渐恢复到基线水平。尽管在EW航线期间睡眠仅显示出轻微损害，但中途停留期间和返回基地后主观时差得分较高。动态活动监测是评估长途飞行后睡眠质量的一种有用方法。
