Key result
Copyright agreement form yields no clinical data comparing main versus assistant referee physical activity.
Why the study?
The physical activity profiles of main referees and assistant referees during official football matches were not well characterized.
Main football referees experience significantly higher physical demands and cardiovascular strain compared to assistant referees during official matches.
Small observational study of referee activity profiles; leaves open whether GPS/HR monitoring informs training or cardiovascular risk in officials.
Background: The aim of this study was to determine physical activity profiles of the main referee and the assistant referee during official championship matches. Material/Methods: Motor activity of 10 referees and 10 assistant referees was studied during 10 matches of the championship rank in the period from April to November 2016. Using a POLAR M400 heart rate monitor with a built-in GPS sensor, the total distance covered during refereeing, the mean and the maximum speed, and the intensity of the refereeing effort were analyzed. Results: It was found that the main referee covered the mean distance of 7.75 km, while the assistant referee 4.40 km. The main referee’s mean heart rate was higher by 25 bt/min than that of the assistant, and the mean maximum heart rates were 184.9 bt/min and 166.6 bt/min, respectively. The assistant referee had the mean maximum running speed of 19.97 km/h. In general, the mean running speed of the main referee was higher than the assistant referee’s mean speed. Conclusions: Differences in physical activity between the main referee and the assistant referee indicate.
