概括

高强度间歇训练 (HIIT) 和中等强度持续训练 (MICT) 都有效地改善超重和肥胖成年人的最大脂肪氧化 (MFO),显示出类似的结果. 最佳的MFO增加了MICT在65-70%的VO2峰值,每周3次60分钟.

科学领域:

运动生理学运动生理学
代谢健康代谢健康
肥胖问题研究研究

背景情况:

超重和肥胖与代谢功能受损有关,包括减少最大脂肪氧化 (MFO).
高强度间歇训练 (HIIT) 和中等强度持续训练 (MICT) 是用于体重管理和代谢改善的常见运动干预措施.
超重和肥胖人口中HIIT与MICT对MFO的慢性影响需要系统评估.

研究的目的:

系统地审查HIIT和MICT对超重和肥胖成年人MFO的慢性影响.
探索影响MFO的因素和与HIIT和MICT的剂量反应关系.

主要方法:

对比HIIT和MICT在超重和肥胖成年人中评估MFO的研究的元分析.
包括13项研究,519名参与者 (HIIT: 136,MICT: 235,对照: 148).
进行了子组,回归和灵敏度分析,以探索异质性和影响因素.

主要成果:

与没有培训相比,HIIT和MICT都显著改善了MFO.
HIIT对MFO产生了显著的有利影响 (MD = 0.07;95%CI [0.03至0.11]).
此外,MICT还对MFO产生了显著的有利影响 (MD = 0.10;95%CI [0.06至0.15]).
在HIIT和MICT之间的直接比较中,MFO变化没有显著差异 (MD = 0.01;95%CI [-0.02到0.04]).
运动强度,模式,BMI和VO2峰值调节了MICT对MFO的影响.

结论:

无论是HIIT还是MICT,在改善超重和肥胖成年人的MFO方面都是有效和可比的.
对于MFO增强的最佳MICT包括65-70%的VO2峰值强度,每周3次,60分钟.
需要进一步的研究,以建立特定的HIIT协议,以改善MFO,因为研究有限和各种协议.

Exercise and Cardiovascular Response

Exercise and Cardiovascular Response

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
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. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

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...
