Process for measuring or predicting a time in a hurdle race of at least one athlete by means of a personalised transponder module positioned on an upper part of the body of the athlete, and a base station of a measurement system, the transponder module comprising at least a signal receiver unit, a processing unit for data, measurements or commands, the processing unit being a microcontroller, a transmitter unit for data and/or measurement and/or command signals, and at least one motion sensor (7, 8) to supply measurement signals to the microcontroller, the motion sensor comprising a gyroscope with one, two or three measurement axes, the process being characterised in that it comprises steps of: - activating the personalised transponder module following the receipt of a wake-up signal in the receiver unit, - measuring, with the gyroscope, a speed or a direction of rotation of the transponder module positioned on an upper part of the body of the athlete, and an angle of rotation of the upper part of the body of the athlete on passage of one or more hurdles during the race, the gyroscope supplying these measurement signals to the microcontroller relative to a forward rotation, before the athlete passes a hurdle and relative to a backward rotation, after the passage of the hurdle defining a change of sign of the direction of rotation on the passage over each hurdle, - transmitting the measurement signals from the gyroscope supplied to the microcontroller, by the transmission unit to the base station, the measurement signals supplied by the gyroscope being processed and sampled in the microcontroller before transmission, or transmitting the measurement signals from the gyroscope by the transmission unit directly to the base station to be processed in the base station after receiving the measurement signals, and - determining, in the microcontroller or in the base station, a passage time over one or more hurdles taking into consideration a change of sign of the direction of rotation in the measurement signals from the gyroscope. - activating the personalised transponder module following the receipt of a wake-up signal in the receiver unit, - measuring, with the gyroscope, a speed or a direction of rotation of the transponder module positioned on an upper part of the body of the athlete, and an angle of rotation of the upper part of the body of the athlete on passage of one or more hurdles during the race, the gyroscope supplying these measurement signals to the microcontroller relative to a forward rotation, before the athlete passes a hurdle and relative to a backward rotation, after the passage of the hurdle defining a change of sign of the direction of rotation on the passage over each hurdle, - transmitting the measurement signals from the gyroscope supplied to the microcontroller, by the transmission unit to the base station, the measurement signals supplied by the gyroscope being processed and sampled in the microcontroller before transmission, or transmitting the measurement signals from the gyroscope by the transmission unit directly to the base station to be processed in the base station after receiving the measurement signals, and - determining, in the microcontroller or in the base station, a passage time over one or more hurdles taking into consideration a change of sign of the direction of rotation in the measurement signals from the gyroscope.
