This Position Statement examines the evidence for physical activity in weight and adiposity loss, prevention of weight and adiposity gain, and in weight regain in adults, and provides guidance on implications for exercise practitioners. Research evidence indicates that >150 min but preferably 300 min per week of aerobic activity of at least moderate intensity is required to prevent weight and adiposity gain, and at least the upper end of this range of activity to prevent weight regain after weight loss. For meaningful weight and total adiposity loss, a minimum of 300-420 min per week of aerobic activity of at least moderate intensity is required. The evidence around the volume of aerobic physical activity required to reduce central adiposity is emerging, and research suggests that it may be substantially less than that required for weight loss. The impact of high-intensity physical activity and resistance exercise for weight management is uncertain. During consultations for weight management, exercise practitioners should advise that metabolic and cardiovascular health benefits can be achieved with physical activity at any weight, and irrespective of weight change.
本立场声明审视了体力活动在体重和体脂减少、预防体重和体脂增加以及成年人体重反弹方面的证据，并就运动从业者的相关影响提供了指导建议。研究证据表明，每周需要进行至少 150 分钟、最好是 300 分钟以上的中等强度以上的有氧运动，才能预防体重和体脂增加，而要预防减肥后体重反弹，则至少需要达到该活动范围的上限。要实现有意义的体重和总体脂减少，每周至少需要进行 300-420 分钟的中等强度以上的有氧运动。目前正在出现有关减少中心性肥胖所需的有氧运动总量的证据，研究表明，其可能远低于减肥所需的运动量。高强度体力活动和抗阻运动对体重管理的影响尚不确定。在进行体重管理咨询时，运动从业者应告知患者，任何体重的体力活动都能带来代谢和心血管健康益处，而与体重变化无关。
