OCCUPATIONAL APPLICATIONSSedentary behavior is a significant health concern among office workers. We completed the same 6-month sit-stand table intervention at work for groups of normal-weight and overweight workers, and compared it to not having sit-stand tables. The intervention caused the intended decrease in sitting time in both groups and a corresponding increase in standing. We did not find compensation effects on physical behavior outside of work. Furthermore, the intervention did not change the composition of fat, lean, and bone mass in either group. Thus, strategies including initiatives to increase physical activity are likely needed to have effects on body composition; and an intervention needs to be sustained for longer than six months for any changes in body composition to be observed.
职业应用
久坐行为是上班族健康的一个重要关注点。我们为体重正常和超重的上班族完成了同样为期 6 个月的坐站交替办公桌干预，并将其与没有坐站交替办公桌的情况进行了比较。该干预在两组中都导致了预期的久坐时间减少，以及相应的站立时间增加。我们没有发现工作以外的身体行为有补偿效应。此外，该干预也没有改变两组的脂肪、瘦体重和骨量的组成。因此，可能需要包括增加身体活动的倡议在内的策略来对身体成分产生影响；并且干预需要持续超过六个月，才能观察到身体成分的任何变化。
