摘要

包括体力活动的休息可以在夜班期间从困倦和疲劳中恢复过来，其效果可能受到昼夜节律类型的影响。33名成年人（M±SD年龄：24.6±4.8岁；55%为女性）参加了5个实验室夜班（2200-0600h），随机分为久坐（SIT; n = 14）或“分手”坐姿（BREAK; n = 19）。参与者完成了昼夜节律类型量表，分为刚性（n = 12）和柔性（n = 11）；慵懒（n = 11）或精力充沛（n = 13）。BREAK参与者每30分钟步行3分钟，速度为3.2公里/小时；所有人都完成了疲劳和困倦量表。线性混合模型显示了夜班（N1-N5）、条件（SIT， BREAK）和疲劳的刚性-灵活性之间的3向相互作用

The relationship between circadian type and physical activity as predictors of sleepiness and fatigue during simulated nightshifts: a randomised controlled trial.

Breaks involving physical activity may provide on-shift recovery from sleepiness and fatigue during nightshifts, with effects potentially influenced by circadian type. Thirty-three adults (M ± SD age: 24.6 ± 4.8y; 55% female) participated in five laboratory nightshifts (2200-0600h) and were randomised to sedentary (SIT; n = 14) or 'breaking-up' sitting (BREAK; n = 19). Participants completed the Circadian Type Inventory, categorising as rigid (n = 12) or flexible (n = 11); and languid (n = 11) or vigorous (n = 13). BREAK participants walked 3-minutes every 30-minutes at 3.2 km/h; all completed fatigue and sleepiness scales. Linear mixed models showed a 3-way interaction between nightshift (N1-N5), condition (SIT, BREAK), and rigidity-flexibility for fatigue (p<.001) and sleepiness (p<.001). Fatigue and sleepiness were greatest on N1 for SIT-Flexible and BREAK-Rigid, with SIT-Rigid experiencing the greatest levels overall. BREAK-Flexible showed no reduction. No 2-way interactions between nightshift and languidity-vigour were found. Breaking up sitting attenuated fatigue and sleepiness for rigid types only. On-shift recovery needs may differ for circadian types.

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
