  • each athlete starts from a starting block.
  • an athlete may still move until he is leaning to be considered ready for the start. Any movement occurring before 0.1 s of the start signaled by a starting pistol of the starting judge must be considered as a false start. This means that the movement of the athlete, which results from the loss of contact of the athlete's hand on the starting ground, is considered a false start after the signal of the starting pistol. On the other hand, any movement of the athlete before the preparation signaled by the starting judge with a disconnection in time of the measuring device, will be considered as the preparations before the start and must not be considered as a false start. In this case, the athlete can only receive a disciplinary warning.

  • the transponder module 1 is provided with at least one movement sensor, and preferably with two movement sensors, such as the accelerometer and the gyroscope.
  • the athlete can move to his final position before the start. Thus, he is supposed to remain ready until the moment of the starting pistol shot fired by the starting judge. During this preparation phase, no other acceleration other than the gravitation of the earth should be seen by the accelerometer. In addition, the gyroscope should also not see a rotation of the body. After firing the starting pistol, the athlete pushes against the support pads 21 for his start of the race. From this moment, the accelerometer measures upward and forward acceleration a and the gyroscope measures rotation or rotational speed ⁇ , as the athlete moves from a squatting position, where their body leans forward approximately 120 ° to an upward (straight) position upon departure.

  • the angle of rotation of the figure 3c is the integration of the signal from the figure 3b and is not useful for the detection of the reaction time, but the signal of the figure 3c is then used to determine if there is truly a false start.
  • the start of an increase in athlete's acceleration at the figure 3a is represented by a vertical line, just like the start of a rotation or speed of rotation of the upper body of the athlete at the figure 3b .
  • the angle of rotation is shown at figure 3c to subsequently determine a real false start. What appears fastest is used as a trigger to determine the reaction time of the athlete, especially after receiving the signals from the transponder modules of each athlete at the start in the base station.
  • the detection of these events in the signals from the sensors can be carried out in the transponder module, which transmits these events or in the base station, if the transponder directly transmits the measuring signals from the sensors.
  • the base station also receives the start signal of the race generated by the starting pistol shot of the starting judge.
  • the time difference between the start signal and the start of the movement defines the reaction time, which must not be less than the time threshold of 0.1 s to validate a good start of the athlete.
  • the basic detection principle described for this invention is relatively similar, to what is done by sensors arranged in the starting block, but with the difference, that the sensors of the transponder module directly measure the movement of the athlete, whereas with sensors arranged in the starting block the athlete's movement is determined indirectly. This can make the determination of the reaction time at the start of the race less precise with the sensors in the starting block, as it cannot detect any type of movement.
  • the acceleration of the motion sensor such as the accelerometer
  • the range of acceleration between athletes can be very large.
  • a gyroscope in the transponder module this allows to have a sure indication of the rotation of the upper part of the athlete's body at the time of departure. This allows to be able to judge in the same way an elite athlete and a junior athlete without taking into account the range of forces or acceleration of each athlete on the starting block.
  • the tilt of the upper body in the squatting position and the tilt of the body following the athlete's first steps or first strides may vary between athletes, it can be concluded that after a body rotation around 30 °, the athlete actually leaves. The start can also be confirmed with his hands, which leave contact with the ground at the start. By integrating the speed of rotation figure 3b measured by the gyroscope, the angle of rotation is obtained in figure 3c of the upper part of the body.
  • the measuring system for the implementation of the method for determining the reaction time can detect the start of acceleration or rotation with a very low threshold and then confirm that it is a real start, when the angle of rotation increases above a defined threshold as shown in dotted lines in figure 3c . If the angle remains below the threshold, for example below 30 ° rotation angle, these are twitching or spasms of the athlete before the start, which should be ignored for the determination of the reaction time to the start. departure.
  • Tremor can be removed from the analysis in a manner very similar to the contractions detected. There are therefore two cases to consider. First, the tremor may have no rotational component. Thus, if significant acceleration is detected, which is not followed directly by significant rotation, then this should not be used as a trigger to determine reaction time. Second, there may be rotational components in the shake. In this case, one can have a significant acceleration and rotation speed detection. However, the angle of rotation will not increase continuously, but will oscillate around 0 °. So, if significant acceleration or rotation is detected, which is not followed by continuously increasing the angle of rotation, this should not be used as a trigger to determine a reaction time and thus a possible false start.
  • the transponder module can include several other sensors, such as a temperature sensor for example.
  • the transponder module can be placed in other places of the athlete's body for a sports competition other than athletics, for example, where a reaction time must be monitored at the start of the race.
