概括
在禁食状态或食状态下进行抵抗训练 (RT) 对年轻成年人来说,肌肉生长和力量的改善类似. 这两种训练方案都在12周内增强了身体组成和身体表现.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 人类表现的人类表现.
背景情况:
- 运动周围的营养时间因其对训练结果的影响而受到辩论.
- 抵抗训练 (RT) 是肌肉缩和力量增加的关键刺激.
- 了解运动前营养状况 (禁食与食) 的影响对于优化训练方案至关重要.
研究的目的:
- 为了比较12周耐力训练在禁食状态和食状态对年轻成年人身体组成和身体表现的影响.
- 研究两种营养状况之间的肌肉缩和神经肌肉适应的潜在差异.
主要方法:
- 在12周的随机对照试验中,年轻人每周两次接受监督抵抗训练.
- 参与者被分配到一个禁食抵抗训练 (Fast-RT) 组或一个食抵抗训练 (Fed-RT) 组.
- 在干预前后评估了身体组成,四头肌肉厚度,最大动力强度和肌肉功率.
主要成果:
- 快速RT和Fed-RT两组都显示四头肌肌肉厚度显著增加,这表明肌肉缩.
- 在两组中都观察到最大动力强度 (长椅压力,膝盖延伸) 的显著改善.
- 肌肉力量 (膝盖延伸) 在禁食和食抵抗训练组中也显示出显著的增长.
- 在任何测量结果中,快速RT和Fed-RT组之间没有发现统计学上显著的差异.
结论:
- 在12周内每周两次进行阻力训练,可以有效地提高年轻人肌肉缩和神经肌肉性能.
- 抵抗训练课程之前的营养状态 (禁食与食) 似乎不会显著影响这些适应.
- 这些发现表明,个人可以选择他们喜欢的运动前营养策略,而不会影响训练引起的肌肉质量和力量的增加.

01:24Metabolic 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...

01:18Metabolic States of the Body: The Postabsorptive State
279
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,...

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...

01:25Metabolic States of the Body: The Absorptive State
670
During the absorptive state, which lasts approximately four hours after a meal, the body absorbs nutrients from the gastrointestinal tract. The carbohydrates, proteins, and lipids we consume are broken down into monosaccharides, amino acids, and free fatty acids for absorption. While carbohydrates and proteins are absorbed as-is, lipids are absorbed in their broken-down forms and then re-esterified into triglycerides within enterocytes before being packaged into chylomicrons. These absorbed...

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.

01:24Muscle Recovery and Fatigue
2.0K
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...
