THE QUICK READ • Many people struggle to dedicate the recommended minimum 30 minutes each day to exercise • A large percentage of many people's waking hours are spent in sedentary office jobs • Researchers compared the metabolic costs (VO2, HR, energy expenditure) for study participants at rest; while seated and typing; while using a stationary foot cycle and typing, and while using a treadmill desk and typing • The study found that both the treadmill typing and cycle typing scenarios resulted in substantially higher energy expenditure than regular seated typing, with no detriment to typing capacity. Given the poor health outcomes associated with sedentary behaviour and sitting time, there is merit to a little extra work at work Pros: This is an interesting study. It is not surprising that typing while walking on a treadmill had the highest energy expenditure, however, if we consider the big picture, the findings indicate the potential of such behaviour to significantly impact caloric expenditure. For example, if a person were to use a treadmill desk for just 30 minutes per day each working day, they would burn 460kcals per week, which over a year would equate to over 22,000 kcals. If a kilo of fat equates to approximately 7,700kcals, then a person could potentially lose 2.8 kilos of fat a year (not that you can lose only fat). If you have a client or patient who is seriously interested in improved weight management, we believe this is a small investment that would be worthwhile, provided they complete the exercise on a regular basis. Cons: None. We price checked and found a number of bike desks (i.e. bike is under the work desk, or a bike with a work desk mounted on it) available in Australia ranging in price from $30 to $600, although these devices are somewhat limited in terms of the intensity of exercise (i.e. watts). Treadmill desks that include the actual treadmill are understandably more expensive at up to $1,400). However, when you consider the accumulative effect of a small daily change in an individual’s energy expenditure at work over a yearly period, these devices can have a significant impact. Given the poor health outcomes associated with sedentary behaviour and sitting time, there is merit to a little extra work at work. References Schuna, J., Hsia, D., Tudor-Locke, C., & Johannsen, N.
