在最大脂肪氧化 (FATmax) 的运动强度是控制肥胖的关键. 建议在肥胖个体中设置FATmax,相对心率,而不是氧气吸收,具体的心率范围是基于身体脂肪百分比.
科学领域:
- 运动生理学 运动生理学
- 肥胖管理 肥胖管理
- 代谢健康 代谢健康
背景情况:
- 在最大脂肪氧化 (FATmax) 时进行运动训练是治疗肥胖和心脏代谢障碍的非药物治疗策略.
- 确定最佳的运动强度和体积对于最大限度地提高这一群体的脂肪氧化是至关重要的.
研究的目的:
- 建立运动强度指导方针,以最大限度地提高肥胖个体的脂肪氧化.
- 为提高肥胖患者的脂肪代谢提供训练量建议.
主要方法:
- 在 EBSCOhost,PubMed 和 Scopus 进行了遵循 PRISMA 准则的系统审查.
- 包括分析肥胖个体最大脂肪氧化 (MFO) 和FATmax的研究,这些研究在分级运动测试中使用间接热量计.
- 使用元回归和集群分析来确定影响MFO和FATmax的因素.
主要成果:
- 选择了64项研究,涵盖了各种人群,包括男性,女性和两性.
- 与相对氧气吸收 (CV: 17.2%) 相比,FATmax的相对心率显示出较低的个体内变化 (CV: 8.8%).
- 诸如年龄,BMI,心肺呼吸能力,人体仪型和MFO计算方法等因素显著影响了MFO值 (R2=0.85).
- 身体脂肪>35%的个体表现出FATmax心率高达HR峰61-66%,而身体脂肪<35%的个体表现出HR峰57-64%.
结论:
- 相对心率是比相对氧气摄入量更可靠的指标,用于确定肥胖个体的FATmax.
- 为了最大限度地氧化脂肪,推的运动强度为61-66%HR,对于身体脂肪>35%的人来说是HR峰值,对于身体脂肪<35%的人来说是57-64%HR峰值.
- 训练量应根据年龄和运动方式进行调整,跑步机运动可能需要比静止骑自行车更低的体积,以获得类似的脂肪氧化益处.

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases.
