运动干预对城市老年群体睡眠障碍的影响

采用实验测评的方法对城市老年失眠症患者进行运动干预,为期三个月的研究发现:药物疗法配合运动干预比单纯的药物治疗效果更好;实验一组和实验二组睡眠结构在NREM浅睡期、NREM深睡期、REM睡眠期、醒觉总时间等四个维度上有非常显著性差异,在入睡潜伏期、睡眠总时间和醒觉次数上没有明显差异,提示实验一组被试睡得更"沉"、更"香",具有更高的睡眠质量,这表明对于失眠症患者来说,有氧运动辅以抗阻训练的综合锻炼方式比单纯的有氧运动效果更好。     

Acute sleep hygiene strategy improves objective sleep latency following a late-evening soccer-specific training session: A randomized controlled trial

ABSTRACT

The aim of this study was to evaluate the effects of sleep hygiene (SH) education on sleep quality in soccer players after a late-evening small-sided-game (SSG) training session. Twenty-nine non-professional players were recruited and allocated to either an experimental group (EG, n = 17) that received SH education, or a control group (CG, n = 12). SSG consisted of 3 × 4 min in a 4vs4, with 3 min of recovery and was performed at 8.00 p.m. Sleep quality was monitored via actigraphy and sleep diary entries before (PRE) and two nights after (POST1, POST2) the SSG. Sleep latency (SL) differed between the two groups at POST1 (4.9 ± 5.4 vs. 15.5 ± 16.1 for EG and CG, respectively; p = 0.017, effect size [ES] = 2.0); SL values were lower at POST1 compared to PRE for the EG (?47%; p = 0.021, ES = 0.6). Subjective sleep quality was better in the EG than the CG at POST1 (8.6 ± 1.0 vs. 7.1 ± 2.0 for EG and CG, respectively; p = 0.016, ES = 0.9) with a significant improvement over PRE-values (+11.0%, p = 0.004, ES = 0.8). Although SL and subjective sleep quality did not decrease significantly from POST1 to POST2 values at POST2 no longer differed significantly form baseline and, hence, indicate that observed effects may be short-lasting. No other objective sleep indices were influenced by late-evening training or SH practices implemented by the EG. Soccer players may benefit from acute SH strategies to reduce the time to sleep onset after late-evening training sessions.     

磁力床垫对中长跑运动员心境状态和睡眠质量的影响

为检测磁力床垫对中长跑运动员心境状态和睡眠质量的影响,采用文献资料法、实验比较法、问卷调查法和数理统计法,以现役29名中长跑运动员为研究对象,其中15名为实验组（使用磁力床垫）、14名为对照组（使用普通床垫）,对他们大运动量训练后的心境状态和睡眠质量展开调查,结果表明：（1）使用磁力床垫的实验组在调节心境状态方面明显优于使用普通床垫的对照组,它能够明显缓解运动员疲劳、恢复精力、抚平慌乱情绪和有效处理纷乱情绪;（2）磁力床垫在中长跑运动员提高睡眠质量方面,主要体现在能够延长睡眠的有效时间。     

褪黑素的生物学作用研究进展

褪黑素是存在于从藻类到人体等多种生物体中的一种激素类化合物,因能使产生黑色素的细胞颜色变浅而得名.国内外对褪黑素的生物学作用开展了广泛的研究,表明其具有调节睡眠、抗衰老、调节免疫、抗肿瘤等多项生理功能.本文主要介绍了褪黑素的生物合成和代谢途径,以及近年来有关褪黑素生物学作用的研究,并对褪黑素的开发前景进行了讨论.     

高原健康房对机体睡眠前后血氧饱和度的影响

目的：探讨高原健康房对移居者睡眠前后血氧饱和度（SaO2）的影响。方法：在海拔3 700 m建立＂高原健康房＂,10名移居高原1年半的健康青年入健康房休息和睡眠10 h,观察受试者睡眠前后SaO2的变化及出健康房后4 h内SaO2的改变,并与普通房间组比较。结果：健康房组第二日晨起安静时SaO2较睡眠前增高5.7%,差别有显著性（P〈0.01）,受试者出健康房后1 h、2 h的SaO2依次为（94.00±1.25）%、（93.40±0.70）%,与普通房间组比较差别均有显著性。结论：建立高原健康房可明显提高人体睡眠后的SaO2,改善睡眠质量。     

Females exposed to 24 h of sleep deprivation do not experience greater physiological strain,but do perceive heat illness symptoms more severely,during exercise-heat stress

There is limited and inconclusive evidence surrounding the physiological and perceptual responses to heat stress while sleep deprived, especially for females. This study aimed to quantify the effect of 24 h sleep deprivation on physiological strain and perceptual markers of heat-related illness in females. Nine females completed two 30-min heat stress tests (HST) separated by 48 h in 39°C, 41% relative humidity at a metabolic heat production of 10 W · kg^?1. The non-sleep deprived HST was followed by the sleep deprivation (SDHST) trial for all participants during the follicular phase of the menstrual cycle. Physiological and perceptual measures were recorded at 5 min intervals during the HSTs. On the cessation of the HSTs, heat illness symptom index (HISI) was completed. HISI scores increased after sleep deprivation by 28 ± 16 versus 20 ± 16 (P = 0.01). Peak (39.40 ± 0.35°C vs. 39.35 ± 0.33°C) and change in rectal temperature (1.91 ± 0.21 vs. 1.93 ± 0.34°C), and whole body sweat rate (1.08 ± 0.31 vs. 1.15 ± 0.36 L · h^?1) did not differ (P > 0.05) between tests. No difference was observed in peak, nor rise in: heart rate, mean skin temperature, perceived exertion or thermal sensation during the HSTs. Twenty-four hours sleep deprivation increased perceptual symptoms associated with heat-related illness; however, no thermoregulatory alterations were observed.

广东省大学生睡眠、早餐和早锻炼意向的调查--以嘉应学院大学生为例

通过对嘉应学院学生睡眠、早餐和早锻炼意向的调查,我们发现62％广东大学生对时间的价值有较高的认识水平;其中可望对早上闲暇时间具有全部支配权的人占61％;73％的人倾向于晚上11点——12点之同的就寝;而晚上10．30之前就寝的人仅占被调查对象总数的5％;88％的人每天睡眠的时间少于8小时;86％的人早餐消费在2元以内。55％的人每星期有2天或2天以上不用早餐;同意5——15分钟锻炼的人点72％;采取跑步、和散步的人占57％,从事球类运动的人占43％。现代大学生的人体模型,这些人思想活跃有比较强的时间价值观;有比较明显的自我意识。一方面渴望自己管理和安排自己的生活,另一方面又缺少必要的自控能力和营养健康知识;他们多数缺乏营养,睡眠不足,缺少足够的体能和精力。
