概括
与阻力运动相结合的乳清蛋白补充剂 (WPS) 与安慰剂相比没有显著增强肝脏脂肪的减少. 然而,WPS显示了对肝酶的潜在益处,以及在减少肝脂肪方面更快的初始反应.
科学领域:
- 运动生理学 运动生理学
- 营养生物化学 营养生物化学
- 代谢健康 代谢健康
背景情况:
- 众所周知,运动和饮食可以减少肝脏脂肪.
- 蛋白质补充可以降低肝脏脂肪积累.
- 运动和乳清蛋白补充剂 (WPS) 对肝脂肪含量 (HFC) 的综合影响需要研究.
研究的目的:
- 为了研究WPS对HFC对久坐不动的男性进行阻力运动和饮食控制的影响.
- 评估肝酶和脂质配置文件的变化.
主要方法:
- 34名久坐不动的男性被随机分配到蛋白质补充剂组 (PSG) 或对照组 (CG).
- PSG每天接受60g的WPS;CG接受了同热量安慰剂.
- 两组都遵循卡路里控制的饮食,并进行监督的抵抗运动4周.
- 使用控制衰减参数 (CAP) 测量肝脏脂肪含量 (HFC);肝脏酶和脂质配置文件也被分析.
主要成果:
- 在4周后,CAP在PSG和CG中显著下降,没有显著的群体相互作用.
- 与CG相比,PSG在干预中期的CAP下降幅度明显更大.
- 氨酸氨基转移酶 (ALT) 水平仅在PSG中显著下降.
- 总胆固醇和LDL胆固醇在两组中都显著下降.
结论:
- WPS可能不会增强阻力运动对HFC和脂质配置文件的整体效果.
- WPS可能对肝脏酶变化有好处.
- 在运动干预期间,WPS可能有助于更快的HFC初始降低.

Muscle Recovery and Fatigue
2.2K
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...

Exercise and Muscle Performance
1.5K
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...

Metabolic States of the Body: Fasting and Starvation
1.6K
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...

Hepatic Drug Clearance: Effect of Protein Binding
255
Hepatic clearance is influenced by protein binding based on the drug's extraction ratio. Drugs with high extraction ratios are considered flow-limited and remain unaffected by protein binding during hepatic clearance. On the other hand, drugs with low extraction ratios may be impacted by plasma protein binding, although the extent of this influence depends on the fraction of the drug bound.
For low-extraction-ratio drugs that are less than 80% protein-bound, minor changes in protein binding...
