概括
耐力训练 (RT) 对低负荷和高负荷的意志疲劳,抑制食欲并改变乙烯酸格林水平. 然而,对其他食欲激素和每日能量摄入的影响很小.
科学领域:
- 运动生理学 运动生理学
- 内分泌学 在内分泌学.
- 运动科学 运动科学 运动科学
背景情况:
- 调节食欲的研究往往忽视了抵抗训练 (RT).
- 之前的研究主要比较了匹配的运动量,而不是不同强度的意志疲劳.
- 了解RT对食欲激素的影响对于运动处方至关重要.
研究的目的:
- 为了比较低负荷 (30% 1-RM) 与高负荷 (90% 1-RM) 阻力训练对意志疲劳对食欲调节的影响.
- 研究不同RT强度后食欲调节激素的变化和主观食欲感知.
- 评估RT对自由生活中的能量摄入的影响.
主要方法:
- 十一名经过抵抗训练的雄性参与了一个交叉设计,有三个条件:控制,30%的1-RM RT和90%的1-RM RT.
- 实践训练课程包括3组5个练习到意志疲劳.
- 测量包括酸格林,GLP-1,PYY,乳酸,食欲感知和每日能量摄入.
主要成果:
- 与对照组相比,30%和90%的1-RM RT都增加了乳酸盐和抑制了酸格林.
- 在30%的1-RM RT后,在运动后60分钟时,酸格林抑制更大.
- 对于两种RT条件,运动后立即抑制食欲,PYY或总体每日能量摄入量没有显著差异.
结论:
- 耐力训练对意志性疲劳,无论负载如何,都会诱导食欲抑制,与酸激素变化相关.
- 观察到对GLP-1和PYY等厌食性激素的影响有限.
- 这项研究表明,尽管有急性食欲抑制,RT对自由生活中的能量摄入的影响可能是最小的.

01:24Muscle Recovery and Fatigue
2.1K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:27Exercise and Muscle Performance
1.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:30Regulation of Food Intake
228
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

01:20Exercise and Cardiovascular Response

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:24Metabolic States of the Body: Fasting and Starvation
1.4K
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...
