时间限制饮食 (TRE) 和抵抗训练可以改善绝经后妇女的身体组成和心脏代谢健康. 本研究将TRE和卡路里限制与抵抗训练进行比较,以评估对骨肌肉组织和代谢健康的影响.
科学领域:
- 老年学是一门学科.
- 营养科学 营养科学
- 运动生理学 运动生理学
背景情况:
- 绝经后的女性体验到身体组成和心脏代谢健康的变化.
- 时间限制饮食 (TRE) 显示出对体重管理的潜力,但其对这种人群的骨肌肉组织 (SMT) 的影响尚不清楚.
- 肥胖和代谢疾病带来风险,特别是在绝经后的妇女中.
研究的目的:
- 研究TRE和TRE与抵抗训练相结合对绝经后妇女的SMT数量,质量和功能的影响.
- 将这些干预措施与对照组 (卡路里限制+抵抗训练) 进行12周的比较.
- 评估12个月后效应的持续性.
主要方法:
- 随机对照试验涉及78名绝经后妇女 (BMI 25-40 kg/m2).
- 三组:TRE (8小时进食窗口),TRE + 抵抗训练和卡路里限制 (CR) + 抵抗训练.
- 干预持续了12周,抵抗训练每周进行3次.
主要成果:
- 通过MRI测量SMT数量的变化.
- 评估的二次结果包括肌肉间脂肪组织 (IMAT),强度,功率,体重,身体组成和心脏代谢风险因素.
结论:
- 该研究将阐明基于TRE的干预措施与传统CR对绝经后妇女的SMT和心脏代谢健康的比较影响.
- 这些发现旨在为肥胖管理和代谢性疾病预防的饮食策略提供信息,同时在这个人口群体中减轻肉症风险.

Exercise and Muscle Performance
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...
Bone Disorders
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...
