The prescription of daily activity

http://m.bjsm.bmj.com/content/early/2015/04/23/bjsports-2015-094618.full.pdf



Proportion of weekly waking hours spent in activity modes, ranging from time spent sitting through to vigorous physical activity (adapted from Townsend et al).18,66 Values R, 1, 2, 3 and 4 represent behavioural “gears” synonymous to a car, where R = “reverse”, 1 and 2 = light activities within daily living, 3 and 4 are moderate to vigorous activities either in daily life or as part of leisure-time pursuits, exercise and sport. Many health promotion and physical activity interventions aim to change people's behaviour by attempting to go from R to 3rd gear, missing targeted interventions in 1st and 2nd gear and thus resulting in behavioural “stalling” (relapse), as would occur in a car if one attempted to go from Reverse into 3rd or 4th gear. Avoiding sedentary behaviour at work fulfils engaging people in activity at gears 1 and 2.
