Full list of author information is available at the end of the articleBackground Sedentary behaviour, which has been defined as ‘any waking behaviour characterized by an energy expend-iture ≤1.5 metabolic equivalents while in a sitting or re-clining posture ’ [1], represents a risk factor for adverse physical and mental health outcomes [2,3], independ-ently of physical activity [4,5]. Of all age groups, older adults tend to spend most time in sedentary activity and least time in physical activity [6]. Behaviour change interventions are needed to replace sedentary behaviour with physical activity, cost-effectively, in older adults. Four types of physical activity are recom-mended in older adulthood: aerobic, muscle-strengthening, flexibility, and balance exercises [7,8]. There is increasing evidence that standing, a light-intensity balance activity, yields cardiometabolic health benefits relative to sitting [9]. The benefits of reducing sedentary behaviour in older adults should therefore be twofold, reducing the risks as-sociated with prolonged sitting, and achieving the benefits associated with physical activity. While decline in physical functioning can impose limits on activity in older adults
