Análisis del rendimiento, percepción de esfuerzo y recuperación y toma de decisión en el arbitraje del fútbol profesionalun estudio del caso

Resumo

The present research analyzes the performance, the perception of effort and recovery, and the decisión making of a professional referee of the first Spanish division in official football matches. A total number of nineteen matches of the 2012/2013 season, in which the protagonist of the investigation was designed as the main referee, were analyzed. The analysis tools used to test the referee’s performance were a GPS heart rate monitor he utilised as an official chronograph in each football match and the video recording of the matches to obtain cinematic parameters (duration, distance run, average and highest speed, time in motion, average speed in motion), physiological ones (medium and maximum heart rate, energy expenditure) and decision making of decisive actions for the game (yellow cards, red cards, penalty shots and goal conceding). Borg’s RPE (Rating Perceived Exertion) and CR10 modified scales (Category scales with Ratio properties) have been used to analyse effort perception. TQR (Total Quality Recovery) scale has been used to measure recovery perception. After having obtained the analysis results, it can be stated that decision making is done under high heart rate frequency in relation to displacement speed. In this sense, at the time of signalling something, heart rate and displacement speed are higher than the average values of the whole of each encounter.
