The main objective of this thesis was to verify the reliability of the diagnostic devise "BOX-CHECK" which our team designed for measuring the force and the time duration of a boxing punch. The device comprises of an accelerometer measuring the acceleration of the boxing bag at the time of a shock which consequently indicates the force of the punch. Further part of the device is the FITRO agility plate with light emitting diode which gives the visual signal to start the punch. FITRO plate connects its circuit by the force of the punch and then measures the time of the duration of the punch. Through their relevant software both devices communicate with the computer displaying the measured values. The verification of the reliability of the device was carried out separately for each parameter: force and time duration of the punch. The experiment was carried out on the sample of boxers (8 female and 4 male) with the average age of 20.6 (+/- 4.4) years, average height of 170.8 (+/- 8.4) cms and average weight of 67.6 (+/- 10) kgs) all with 2.5 (+/- 1.7) years of boxing training. ICC reliability index was used to process the measured data. The value of the reliability of the device for the time duration of the punch was established at 0.882 and at 0.969 for the force of the punch. In conclusion we can state that the diagnostic device "BOX-CHECK" is sufficiently reliable for the use in the training process.
