Abstract

A device for use in connection with sports and athletics exercise for recording overstep in relation to a predetermined reference line, which may be a start line or a take-off line for measuring the length of a jump or throw. The device comprises a step cushion (7), which is located in direct connection to said reference line (20) and extends along said line, and which airtight encloses a cavity (11) of a definite volume provided with air of a predetermined pressure, and which is capable upon being loaded on its upper surface to instantaneously reduce the volume of said cavity (11) for obtaining a pressure increase, and a pressure indicator (17) is connected to said cavity (11) which in response to such pressure increase initiates a signal member (18) to emit an optic and/or acustic signal.
