Physical activity in the management of obesity in adults: A position statement from Exercise and Sport Science Australia

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.

Weight loss may not be a primary objective or appropriate for some individuals, including those with comorbidities, the elderly, and those for whom these volumes are not possible or are difficult to achieve. Other physical activity approaches (e.g. resistance exercise, high-intensity exercise, less structured physical activity) can be used to achieve broader health goals for individuals with weight management problems. Agreeing on appropriate physical activity goals and the adoption of a progressive approach should be undertaken to ensure that these volume targets do not dissuade people from physical activity participation.
