| Summary: | Currently, most of the powerlifting competitions are conducted without any digital systems, which will be responsible for the fairness of evaluation of participants. Since the evaluation of participants is carried out by judges, the following problems follow: Errors when checking the correctness of the exercise A large number of judges are needed to conduct competitions Occurrence of errors when logging competitions (entering all results manually) To solve this problem, we have decided to create the prototype of a digital referee system designed to analyze the correctness of the athlete's performance of the Chest Press exercise on the MB Barbell Chest Press / Bench Press simulator, based on the readings of a three-axis accelerometer provided by MB Barbell. The developed prototype allows to fix the initial and final positions of the athlete's hands, with the calculation of the movement of the hands performing the exercises. Before performing the working approach, calibration is performed, consisting of an arbitrary number of repetitions on a simulator with an empty weight. Calibration determines the extreme positions of the hands when performing an exercise on this simulator for this athlete. All calibration measurement results are entered into a special calibration table, according to which, in the future, the average calibration value of the amplitude of the athlete's arm movement is calculated. Thus, the developed system has the following functions: Fixing the correctness of the exercise without the participation of a judge The function of individual calibration for each athlete Implementation of the electronic protocol of the competition in real time with integration on the electronic scoreboard |
