The aim was to study the effect of rotation direction on the time-of-day variations of cortisol, fatigue and sleep in sound engineers broadcasting in a life show. The salivary cortisol and ratings of stress, sleepiness and fatigue were followed at three hour intervals in 25 sound engineers: 13 working very fast forward-rotating shifts and 12 working very fast backward-rotating shifts. Cortisol was assessed with radioimmunological kits. The participants reported for stress symptoms and filled sleep diary. Cortisol retained the typical diurnal pattern. The rotation direction interacted with the shift significantly and as a result higher cortisol values during the morning and night shifts in the backward rotating group were found as well as worse quality of sleep. Higher salivary cortisol during morning and night shifts and worse quality of sleep in engineers working very fast backward-rotating shifts may be an indication for insufficient recovery.
目的是研究旋转方向对在直播节目中进行广播的音响工程师皮质醇、疲劳和睡眠的昼夜变化的影响。对25名音响工程师每隔3小时跟踪测量唾液皮质醇以及压力、嗜睡和疲劳评分：13名从事非常快速的向前旋转轮班工作，12名从事非常快速的向后旋转轮班工作。使用放射免疫试剂盒评估皮质醇。参与者报告压力症状并填写睡眠日记。皮质醇保持典型的昼夜模式。旋转方向与轮班有显著交互作用，结果发现向后旋转组在早班和夜班期间的皮质醇值更高，睡眠质量也更差。从事非常快速的向后旋转轮班工作的工程师在早班和夜班期间唾液皮质醇水平较高且睡眠质量较差，这可能表明恢复不足。
