Claim:
1. A system for generating feedback on a subject's running style, the system comprising: a pressure sensitive surface with a plurality of pressure sensors for generating an electronic signal as a function of a pressure exerted on said pressure sensitive surface; a clock arranged for providing timestamp information; a memory arranged for storage and retrieval of data; a readout device arranged for reading out the plurality of pressure sensors and the clock and storing data in the memory comprising a time-dependent measurement of a moving center of pressure exerted by a subject's foot on the pressure sensitive surface, the moving center of pressure forming a pressure gait line at least distinguished along a forward axis of a running direction; and a feedback device arranged for generating one or more of a visual, audio, or haptic feedback signal and controlled by a processor, said processor arranged for: reading the data from the memory; determining from the data a first timestamp at a first registered moment that a front portion of the subject's foot starts touching the ground; determining from the data a second timestamp at a moment that the center of pressure reaches a most backwards registered position along the gait line with respect to the forward axis; calculating a time difference between the first and second timestamps as a defined loading time; and controlling the feedback device to generate a feedback signal as a function of the loading time.
