<p>An Ergometer, preferably personally carried and includes an accelerometer (1). The accelerometer (1) is very sensitive and is adapted for giving a continuous signal corresponding to the momentary acceleration. The ergometer further includes electronic means (2) for calculating momentarily developed force, power and/or energy on the basis of the acceleration signal. The ergometer in one embodiment has a display or indication means (11), e.g. adapted in digital or analogue form to show values for momentary force (11a), momentary force (11a), momentary power (11b) and/or developed work (11c) or energy corresponding thereto and expended by a person. In another embodiment, the ergometer has memory or registration means (12) adapted for storing values at different times for momentary force (11a), momentary power (11b) and/or developed power (11c) or energy corresponding thereto, rendered by a person. It can have means which transmit a signal when a predetermined value of the momentary power and/or the developed work has been attained. The ergometer can finally also have a) a means (3) for measuring and/or registering the number of heartbeats and b) a means for calculating the value of force, power and/or developed work in relation to heart activity. </p> |
