There is a need to reliably measure the daily movement pattern, that is everything from sedentary and low-intensity activity to moderate or high-intensity exercise. Asking a person to report how much they sit or move is simple but unreliable.
At GIH, we have been working for several years to measure the daily activity pattern using objective methods. They are small meters, so-called accelerometers, and inclinometers, which are worn on the hip in a belt, around the wrist, or attached to the thigh.
When a person moves, acceleration occurs, and this is what the accelerometer registers. The more intensely the person moves, the greater the rash. Sitting still or standing still has no effect. If the inclinometer is attached to the thigh, it can determine whether the person is standing or sitting.
In this way, in various studies and situations, we can determine how much a person sits or moves and how the activity or sitting still is distributed over the day or week. We can then describe this or relate it to different outcomes, such as well-being, disease risk, or performance.
