Analysis of the type and quantity of activity of referees in first division football in Slovenia

Vloga sodnikov v nogometu je pomembnakljub temu ugotavljamo, da je relativno malo literature o nogometnem sojenju in sodnikih. Cilj našega diplomskega dela je bil ugotoviti vrsto in količino aktivnosti nogometnih sodnikov v prvi slovenski ligi in v primerjavi s sodniki na velikih tekmovanjih ter v drugih elitnih nogometnih državah (Italija in Anglija). Glavna raziskava je bila opravljena na 12 prvoligaških glavnih sodnikih (starost: 37±5,2), kar predstavlja 75% populacije. Izvedli smo pregled podatkov o srčnem utripu, zbranih preko spletnega sistema Polar Flow na tekmah 1. SNL v sezoni 2017/2018. Rezultati kažejo, da se sodniki med tekmo gibljejo v intervalu med 70% in 90% največje frekvence srčnega utripa. Med drugim polčasom smo, v primerjavi s prvim, ugotovili statistično značilno nižjo frekvenco srčnega utripa (p=0,000) za 3,11 udarca na minuto Podatki tudi kažejo, da imajo slovenski sodniki, z izjemo drugega polčasa nogometne tekme, v povprečju statistično značilno višjo frekvenco srčnega utripa kot sodniki na Evropskem prvenstvu 2000 (p=0,025), a nižjo v primerjavi z angleškimi in italijanskimi sodniki (p=0,000). Na osnovi podatkov bi lahko sklepali o dobri telesni pripravljenosti slovenskih sodnikovprimerljivi mednarodnim sodnikom na najvišji ravni.The role and influence of football referees is very importantthey are regarded as the 23rd player on the field. The aim of our research was to determine the nature and quantity of on-field activities of football referees in the first Slovenian division and in comparison with referees at the highest level and from other elite football countries (Italy and England). The main focus of the study was conducted on 12 first division referees (age 37±5.2), representing 75% of the population. We examined the heart rate data from the 1.SNL matches of the 2017/2018 season, collected through the Polar Flow online system. The results show, that the referees in-game work rate is between 70% and 90% of their HRmax. Findings show, that the heart rate of the Slovenian referees is statistically significantly lower in the second half of the game (p = 0,000) by 3,11 beats per minute. We also found that the Slovenian referees, with the exception of the second half of the games, have an average statistical significance in higher heart rate, compared to the results of the referees at the European Championship 2000 (p = 0,025), but lower heart rate compared to English and Italian first division referees (p = 0,000). Based on the results we can conclude that the Slovenian referees have good physical fitness levelscomparable to international referees at the highest level
