We have long reported that treadmill desks are great for productivity, walking is medically proven to stimulate cognitive abilities - increasing your attention levels. We admit, the effects aren't immediate, it can certainly take a day or two to get familiar with your new way of working - after all you're breaking the habit of a lifetime! But once you find your pace and get used to walking at your desk you'll be amazed at what a little light exercise whilst you work can do for your productivity.
The University of Minnesota recently conducted a survey of 40 office workers, they were each asked to perform their usual daily tasks, but on a treadmill desk. After an initial drop in productivity whilst the users adjusted, the users productivity levels rose by 1 point on the specially devised scale used in the experiment.
A Canadian office also installed treadmill 'hot-desks' in each department, they wanted their employees to use the desks for part of the day in order to perform certain tasks - the study concluded that the treadmill desks were particularly beneficial to those in a creative role.
