在饮食需求充足且无睡眠障碍的男性中，在连续两晚分别经历8小时或4小时睡眠剥夺后，急性摄入天冬氨酸锌镁对睡眠和早晨斯特鲁普干扰任务表现是否有益？

Abstract

PURPOSE

Purpose: We examined whether supplementation of zinc magnesium aspartate (ZMA) in two groups of males, either partially sleep-restricted (4 h) or with habitual sleep (8 h) for 2 nights, was beneficial for sleep and subsequent morning Stroop performance.

METHODS

Participants were randomly allocated to two independent groups who either had 4 h (33 males) or 8 h (36 males) sleep for two nights. Using a double-blinded, randomised counterbalanced design, they then completed five sessions, (i) two familiarisation sessions including 7 days of sleep and dietary intake, (ii) three conditions with 4 h or 8 h sleep and either NoPill control (NoPill), placebo (PLAC) or ZMA (ZMA). Sleep was assessed by actimetry and sleep questionnaires, and cognitive performance was assessed by the Stroop test. The data were analysed using a general linear model with repeated measures.

RESULTS

A main effect for "sleep" (4 or 8 h) was found, where more opportunity to sleep resulted in better "sleep" metrics (both objective and subjective) as well as better Stroop scores (lower colour-interference and word-interference scores and lower error in words). No main effect for "Pill" was found other than the mood state depression, where subjective ratings for the PLAC group were lower than the other two conditions. Interactions were found in anger, ease to sleep and waking time.

CONCLUSION

Having 8 h opportunity to sleep resulted in better "sleep" metrics as well as better Stroop scores compared to 4 h. Supplementation of ZMA for 4 or 8 h for 2 nights had no effect on subsequent morning cognitive performance but reduced sleep or total sleep time by ~0.46 h compared to the other conditions. An interaction was found where sleep time was reduced by ~0.94 h in the ZMA group in the 8 h condition compared to NoPill or PLAC.

摘要

目的

我们研究了两组男性，一组部分睡眠受限（4小时），另一组保持习惯睡眠（8小时），连续两晚补充天门冬氨酸锌镁（ZMA）是否对睡眠及随后早晨的斯特鲁普测试表现有益。

方法

参与者被随机分配到两个独立组，一组连续两晚睡4小时（33名男性），另一组连续两晚睡8小时（36名男性）。采用双盲、随机平衡设计，他们随后完成五个阶段，（i）两个熟悉阶段，包括7天的睡眠和饮食摄入情况，（ii）三个条件，即4小时或8小时睡眠，以及无药物对照组（NoPill）、安慰剂组（PLAC）或ZMA组（ZMA）。通过活动记录仪和睡眠问卷评估睡眠情况，通过斯特鲁普测试评估认知表现。使用重复测量的一般线性模型分析数据。

结果

发现了“睡眠”（4小时或8小时）的主效应，即更多的睡眠机会导致更好的“睡眠”指标（包括客观和主观指标）以及更好的斯特鲁普测试分数（更低的颜色干扰和单词干扰分数以及更低的单词错误率）。除了情绪状态抑郁方面，未发现“药物”的主效应，在该方面，PLAC组的主观评分低于其他两个条件组。在愤怒、入睡难易程度和醒来时间方面发现了交互作用。

结论

与睡4小时相比，有8小时的睡眠机会可带来更好的“睡眠”指标以及更好的斯特鲁普测试分数。连续两晚4小时或8小时补充ZMA对随后早晨的认知表现没有影响，但与其他条件相比，睡眠或总睡眠时间减少了约0.46小时。发现了一个交互作用，在8小时睡眠条件下，与NoPill或PLAC组相比，ZMA组的睡眠时间减少了约0.94小时。
