概括
中度至强度的体力活动 (MVPA) 可能会增加行为性减肥的个体的能量摄入量 (EI). 较低的身体质量指数 (BMI) 和经过炼后更高的感知补充需求放大了这种效应,可能会阻碍减肥.
科学领域:
- 行为医学是一种行为医学.
- 肥胖研究的研究.
- 运动生理学 运动生理学
背景情况:
- 行为减肥 (BWL) 计划结合了减少能量摄入 (EI) 和中度至强烈的体力活动 (MVPA).
- MVPA对后续EI的急性影响,以及其对身体质量指数 (BMI) 和运动后认知等个人因素的依赖,仍然是BWL背景下的研究领域.
研究的目的:
- 调查BMI和MVPA后认知是否适度了参与BWL计划的成年人中MVPA和随后的EI之间的关系.
- 了解MVPA后EI的急性变化可能如何影响整体每日EI和减肥结果.
主要方法:
- 在BWL试验中,91名超重/肥胖的成年人在治疗中期评估期间提供了数据.
- 使用Fitbit设备跟踪MVPA,通过自我监测应用程序记录EI,并从体重和身高计算BMI.
- 评估的MVPA后认知包括允许吃东西,感知需要补充和减肥动机.
主要成果:
- 较低的BMI和更高的感知补充需求显著放大了MVPA和EI在运动后2小时的积极关联.
- 在MVPA后的2小时窗口中增加的EI趋势与更大的整体每日EI相关.
- 在治疗中期的评估中,更大的每日EI与百分比体重减轻有负面联系.
结论:
- 体重指数较低,感觉更需要补充的个体在MVP后经历了更高的EI.
- 在MVPA之后,EI的急性增加可能预测每日EI的增加,这可能会阻碍体重减轻.
- 建议在BWL计划中的特定子组中进行针对性干预来管理MVPA后的EI,以保持饮食遵守并提高减肥效率.

The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

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.

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
