BACKGROUND
Different types of mattresses affect sleep quality and waking muscle power. Whether manual muscle testing (MMT) predicts the cardiovascular effects of the bedding system was explored using ten healthy young men.
METHODS
For each participant, two bedding systems, one inducing the strongest limb muscle force (strong bedding system) and the other inducing the weakest limb force (weak bedding system), were identified using MMT. Each bedding system, in total five mattresses and eight pillows of different firmness, was used for two continuous weeks at the participant's home in a random and double-blind sequence. A sleep log, a questionnaire, and a polysomnography were used to differentiate the two bedding systems.
RESULTS AND CONCLUSION
Heart rate variability and arterial pressure variability analyses showed that the strong bedding system resulted in decreased cardiovascular sympathetic modulation, increased cardiac vagal activity, and increased baroreceptor reflex sensitivity during sleep as compared to the weak bedding system. Different bedding systems have distinct cardiovascular effects during sleep that can be predicted by MMT.
背景
不同类型的床垫会影响睡眠质量和清醒时的肌肉力量。我们使用10名健康年轻男性探究了徒手肌力测试（MMT）能否预测床上用品系统对心血管的影响。
方法
对于每位参与者，通过MMT确定两种床上用品系统，一种能诱导最强的肢体肌肉力量（强力床上用品系统），另一种能诱导最弱的肢体力量（弱力床上用品系统）。每种床上用品系统，总共包括五张不同硬度的床垫和八个枕头，在参与者家中以随机双盲顺序连续使用两周。使用睡眠日志、问卷和多导睡眠图来区分这两种床上用品系统。
结果与结论
心率变异性和动脉压变异性分析表明，与弱力床上用品系统相比，强力床上用品系统在睡眠期间导致心血管交感神经调节降低、心脏迷走神经活动增加以及压力感受器反射敏感性增加。不同的床上用品系统在睡眠期间具有不同的心血管影响，这可以通过MMT预测。
