21. An activity measuring device for recording the activity of a test subject, the activity measuring device including at least one acceleration sensor configured to continuously measure, in three spatial directions that are at right angles to each other, body accelerations underlying the momentary physical activity of the test subject, wherein the activity measuring device is configured to determine a current state of motion based upon the continuous measurements of the body accelerations of the test subject, and the activity measuring device is further configured to distinguish between states of motion of walking and jogging associated with the test subject by determining a mean difference from a mean of measured values in a series of measurements for each spatial axis direction, and by further comparing the mean difference determined for each spatial axis direction with a corresponding threshold value assigned to each spatial axis direction.

22. An activity measuring device for recording the activity of a test subject, the activity measuring device including at least one acceleration sensor configured to continuously measure, in three spatial directions that are at right angles to each other, body accelerations underlying the momentary physical activity of the test subject, wherein the activity measuring device is configured to determine a current state of motion based upon the continuous measurements of the body accelerations of the test subject, and the activity measuring device is further configured to distinguish between states of motion of lying, standing and sitting associated with the test subject for each spatial axis direction by determining a mean for each spatial axis direction from a corresponding series of measurements determined for each spatial axis direction, and by further comparing each mean with a corresponding assigned threshold value for each spatial direction.
