Abstract: A measuring device and a method estimates the quantity and quality of exercises performed having an advantageous impact on cholesterol metabolism. In the method, accelerations exerted on a person during daily exercise performed by the person are continuously recorded by a measuring device including an acceleration transducer. The recorded results are visible in the measuring device or an external device. Based on the received feedback, the person can change the quantity and quality of his/her exercise so that it has an advantageous impact on cholesterol metabolism.

Abstract: The invention relates to a method and device arrangement for determining and presenting the change of bone mass caused by accelerations having an impact on the body and representing the amount and intensity of exercise. The device arrangement according to the invention includes a transducer unit, a data transfer medium, a server and a database connected to it. The invention also relates to a transducer unit used in the device arrangement and a method utilizing the device arrangement for measuring and analyzing the intensity, amount and effectiveness of the exercise.

Abstract: The invention relates to a method for measuring the length of steps, a measuring arrangement utilizing the method and a sound transmitter and a sound receiver utilized in the measuring arrangement. In the method according to the invention, the distance of the person performing the measurement from a certain fixed point is measured by means of synchronized sound frequency pulses. The number of steps is measured by means of an acceleration transducer carried along by the person. The length of steps is obtained by dividing the distance advanced by the number of steps.
