概括
替换日修改禁食减少了卡路里摄入量,但没有影响健康成年人的睡眠质量或整体体力活动水平超过12天. 禁食日显示静坐时间增加和活动减少,在非禁食日进行补偿.
科学领域:
- 营养科学 营养科学
- 睡眠科学 睡眠科学
- 运动生理学 运动生理学
背景情况:
- 替代日修改禁食 (ADMF) 是一种饮食方案,涉及严重卡路里限制和正常饮食的周期.
- 在健康成年人中,ADMF对睡眠质量,体力活动和身体组成的影响需要进一步调查.
- 之前的研究表明间歇性禁食对代谢健康的潜在益处,但其对日常功能的影响不太清楚.
研究的目的:
- 为了研究12天交替日修改的禁食方案对健康成年人的睡眠参数,身体活动,身体组成和情绪的影响.
- 为了确定ADMF是否影响睡眠时间,效率,延迟或在入睡后醒来.
- 评估身体活动指标的变化,包括步骤,能量消耗,久坐时间和中度至强度的身体活动.
主要方法:
- 这是一项随机对照试验,涉及42名健康成年人 (平均年龄为22.5岁).
- 参与者接受了为期12天的替代日修改禁食协议或作为对照组.
- 测量包括睡眠评估 (持续时间,效率,延迟,睡眠开始后醒来),身体活动 (步骤,能量消耗,久坐时间,活动强度),身体组成和情绪.
主要成果:
- 与对照组 (p=0.03) 相比,ADMF组消耗的卡路里显著减少 (25.8%).
- 在体质指数,脂肪质量或瘦肉质量变化方面,没有观察到群体之间的显著差异.
- 与非禁食日相比,在禁食日,ADMF参与者表现出较长的静坐时间 (+34.5分钟),减少步骤 (-1100步),以及中度至剧烈体力活动 (-27.2分钟) 的减少. 总体上,每日的能量消耗和睡眠参数在不同组之间保持不变.
结论:
- 替换日修改禁食不会显著改变健康成年人的睡眠持续时间,效率,延迟或睡眠开始后的觉醒,即使是那些自我报告睡眠质量不佳的人.
- 虽然整体的日常体力活动水平没有受到影响,但ADMF导致禁食日的久坐行为增加和体力活动减少,而非禁食日的补偿性增加.
- 超过12天的ADMF在这个队列中没有导致身体组成 (BMI,脂肪质量,肌肉质量) 或每日能量消耗的显著变化.

Insufficient Sleep and Sleep Deprivation
136
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Metabolic States of the Body: Fasting and Starvation
1.2K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Sleep-Wake Cycles
1.2K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

Sleep Apnea
131
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Metabolic States of the Body: The Postabsorptive State
277
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Management of Insomnia
235
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
