概括
奶酪补充剂改善了老年女性的肌肉质量和力量,这些女性可能患有肉症. 这种干预可以通过影响细胞能量代谢来支持肌肉健康.
科学领域:
- 老年学和营养科学研究
- 肌肉生理学和新陈代谢
背景情况:
- 以前的研究表明,富含营养的奶酪补充剂对健康老年人的肉症标志物有好处.
- 奶酪对可能 Sarcopenia 的个体的影响仍然未被探索.
研究的目的:
- 研究原始和黄金奶酪补充剂对老年妇女肌肉质量和力量的影响,可能患有肉症.
主要方法:
- 一项为期90天的随机对照试验 (RCT) 涉及68名可能患有肉症的女性 (60-80岁).
- 参与者被分配到对照组,原始奶酪组 (9.0g蛋白质,322.8mg) 或黄金奶酪组 (12.7g蛋白质,802.1mg).
- 测量包括骨肌肉质量指数 (SMI),手握强度和血液标记在试验的基线,中途和结束时.
主要成果:
- 与对照组相比,这两组奶酪的骨肌肉质量指数 (SMI) 显著增加.
- 黄金奶酪组表现出手握力比对照组增加得更大.
- 在这两组奶酪中,肌素/细胞素C水平显著增加;原始奶酪也增加了自由和总肉素.
结论:
- 原始和金色奶酪补充剂有效地增强了可能患有肉症的老年女性的肌肉质量和力量.
- 这些发现表明涉及肌肉细胞能量代谢的潜在机制.
- 这项研究提供了关于奶酪作为老年人肉症有益的饮食干预措施的证据.

Bone Disorders
3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Exercise 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...
