概括

运动显著提高了老年人中的流星类蛋白 (Metrnl) 水平,改善身体功能并减少炎症. 联合阻力和步行运动显示出最强的益处,包括认知收益.

科学领域:

运动生理学运动生理学
生物标志物生物标志物
老年学是一门学科.

背景情况:

流星类蛋白质 (Metrnl) 在炎症,新陈代谢和肌肉再生中发挥作用.
对于与年龄有关的疾病,Metrnl 是一个潜在的治疗点.
对于老年人来说,了解运动引起的Metrnl变化至关重要.

研究的目的:

研究老年人运动诱导的Metrnl变化和炎症标志物,身体功能和认知表现之间的关系.
为了检查12周的运动干预对循环Metrnl水平的影响.
确定Metrnl作为社区居住的老年人 (≥65岁) 的新生物标志物.

主要方法:

90名老年人的随机对照试验.
三组:行走 (WG),抵抗和行走 (RWG) 和主动控制 (CG).
中等强度运动干预 (12周) 干预前后评估肌肉,身体和认知功能.

主要成果:

与CG相比,WG和RWG中的血清Metrnl水平显著增加 (p < .005).
测量变化与减少炎症 (IL-6,TNF-α),改善体力活动和增强体力功能 (定时起床和起床,五次坐立测试) 相关联.
RWG证明了更强的关联,包括认知能力的改善 (Stroop测试),增加手握强度和减少脂肪质量.

结论:

在老年人中,Metrnl作为一种生物标志物,将运动与减少炎症以及改善身体和认知结果联系起来.
运动干预措施,特别是联合抵抗和步行,可以调节Metrnl水平.
这些发现支持Metrnl在为老龄化人口开发有针对性的以运动为基础的疗法的相关性.

关键词:

Exercise and Cardiac Output

Exercise and Cardiac Output

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...

Exercise and Muscle Performance

Exercise and Muscle Performance

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...
