概括
将高强度间歇训练 (HIIT) 添加到生活方式干预措施中,可以在短期内提高超重年轻人的体力活动. 然而,对中度至强度体力活动 (MVPA) 的好处在12个月后没有持续下去.
科学领域:
- 儿童肥胖症 儿童肥胖症
- 运动生理学 运动生理学
- 行为健康 行为健康
背景情况:
- 超重或肥胖的儿童和青少年与他们的瘦身同龄人相比,体力活动水平较低.
- 了解有效的干预措施来增加这个人口群体的体育活动对于公共卫生至关重要.
研究的目的:
- 评估将为期3个月的高强度间歇训练 (HIIT) 计划纳入为期12个月的生活方式干预对超重/肥胖年轻人身体活动 (PA) 的影响.
- 评估中度至强度体力活动 (MVPA) 和久坐时间的变化.
主要方法:
- 一项随机对照试验,涉及173名超重或肥胖的儿童和青少年.
- 参与者被分配到12个月的生活方式干预 (控制) 或12个月的生活方式干预加上3个月的HIIT计划.
- 在基线,3个月和12个月使用加速度计测量身体活动.
主要成果:
- 与对照组 (每天增加0.9分钟) 相比,HIIT组在3个月后显著增加了MVPA (每天增加8.3分钟).
- 在12个月后,两组之间没有观察到MVPA的显著差异,MVPA恢复到基线水平.
- 在12个月的时间里,这两个组的静坐时间显著增加.
- 剧烈活动的变化与BMIz-score (r=-0.26,p=0.02) 的变化相反相关.
结论:
- 添加到生活方式干预的3个月的HIIT计划可以暂时增加超重/肥胖年轻人的MVPA.
- 对MVPA的积极影响在12个月后没有持续.
- 剧烈活动和BMIz-score之间的反向关系表明,高强度运动在儿童肥胖管理中的重要性.

Exercise and Cardiac Output
1.8K
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.

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...

Obesity
1.1K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
