概括
在身体活跃的成年人中,补充Bacillus clausii UBBC-07和乳清蛋白显著改善了必需氨基酸 (EAA) 的生物可用性和肌肉强度标志物. 这种益生菌增强了蛋白质的吸收和运动表现,没有任何不良影响.
科学领域:
- 营养生物化学 营养生物化学
- 运动生理学 运动生理学
- 微生物学 微生物学
背景情况:
- 益生菌被认为有助于增强胃肠道健康和营养吸收.
- 百日 (Shouchella clausii) UBBC-07是一种益生菌菌株,对营养物质的生物可用性有潜在的好处.
- 乳清蛋白是运动员常用的补充剂,以支持肌肉生长和恢复.
研究的目的:
- 评估Bacillus clausii UBBC-07与乳清蛋白结合对必需氨基酸 (EAA) 生物可用性的影响.
- 评估这种补充剂对身体活跃的年轻成年人肌肉力量和性能的影响.
主要方法:
- 这是一项为期60天的双盲,随机,受控试验,涉及70名身体活跃的男性.
- 参与者每天接受Bacillus clausii UBBC-07 (2亿CFU) +乳清蛋白 (20g) 或安慰剂 +乳清蛋白.
- 使用HPLC-FLD测量循环氨基酸水平,并通过腿按压,死和垂直跳跃测试来评估力量.
主要成果:
- 与安慰剂相比,益生菌组的总循环EAA (p=0.002) 和分支链氨基酸 (BCAA) (p=0.001) 显著增加.
- 在益生菌组中,特定的BCAA,包括异黄素,素和素,显著增加.
- 在益生菌组 (p=0.045) 中,一次重复最大腿按压的改善显著更大,死力和垂直跳跃的改善趋势更为明显.
结论:
- 补充Bacillus clausii UBBC-07可以增强蛋白质的吸收,从而提高EAA的生物可用性.
- 观察到的BCAA的增加与增强的肌肉力量相关,这可以通过改善腿部压力表现来证明.

Proteins: Dietary Sources and Requirements
285
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Overview of Protein Metabolism

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...
