ABSTRACT:
A process and system for measuring information concerning movement factors, and to values, which can be calculated therefrom, particularly stride length, stride number, stride time and running time, via a pair of shoes (1, 2), each of which is provided with a transmitter (S1 or S2), a receiver (E1 or E2), and a signal time measuring device (counter Z1 or Z2). A direct signal (t.sub.dir.) emitted by the front shoe (1) in response to ground contact is received by the rearward shoe (2), is transferred in conformance to time parameters to the first shoe 1 as a reflected signal (refl.). The direct and reflected signals as well as the readouts of both counters (Z1 and Z2) are transmitted to a computer unit, particularly, a high-frequency computer unit for use in determination of the movement information.
