Abstract

The aim of this study was to determine physical activity profiles of the main referee and the assistant referee during official Liga 1 Shopee 2019/2020.
Motor activity of 5 referees (FIFA) and 7 assistant referees (FIFA) was studied during 12 matches of shopee liga 1 rank in the period from January to March 2020. Using a POLAR M600 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 8.62 km, while the assistant referee 4.41 km. The main referee^s mean heart rate was higher by 20 bt/min than that of the assistant, and the mean maximum heart rates were 1 bt/min1 186 and 161 bt/min, respectively. The assistant referee had the mean maximum running speed of 21.71 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 a need for different fitness training in order to prepare them for presiding over a match.
