超重和肥胖是严重的公共卫生问题，因为它们与许多慢性健康状况有关。超重是能量摄入和能量消耗不平衡的结果。体力活动是能量消耗中变化最大的部分，因此一直是调整体重的行为干预的目标。看来，体力活动是长期控制体重的一个重要组成部分，因此应该规定足够的活动水平来抗击肥胖症流行。尽管有证据表明，30分钟的中等强度体力活动可能会改善健康状况，但控制体重所需的体力活动量可能是每天30分钟。越来越多的科学文献表明，为了最大限度地减轻体重和防止体重显著回升，至少60分钟的中等强度体力活动可能是必要的。此外，充足的体力活动似乎对预防体重增加和肥胖的发展很重要。与体重相比，体力活动似乎对与健康有关的结果也有独立的影响，这表明适当的活动水平可能抵消体重对健康结果的负面影响，因此，重要的是有针对性的干预战略，以促进采用和维持适量的体力活动来控制体重。
Overweight and obesity present significant public health concerns because of the link with numerous chronic health conditions. Excess body weight is a result of an imbalance between energy intake and energy expenditure. Physical activity is the most variable component of energy expenditure and therefore has been the target of behavioral interventions to modify body weight. It appears that physical activity is an important component on long-term weight control, and therefore adequate levels of activity should be prescribed to combat the obesity epidemic. Although there is evidence that 30 min of moderate-intensity physical activity may improve health outcomes, the amount of physical activity that may be necessary to control body weight may be > 30 min/d. There is a growing body of scientific literature suggesting that at least 60 min of moderate-intensity physical activity may be necessary to maximize weight loss and prevent significant weight regain. Moreover, adequate levels of physical activity appear to be important for the prevention of weight gain and the development of obesity. Physical activity also appears to have an independent effect on health-related outcomes when compared with body weight, suggesting that adequate levels of activity may counteract the negative influence of body weight on health outcomes, Thus, it is important to target intervention strategies to facilitate the adoption and maintenance of an adequate amount of physical activity to control body weight.
