摘要:Abstract The aim of this research was to survey the relationship between the number of crowds with anxiety and the function of the soccer premier leaguecircle2s referee. 45 Iranian soccer premier leaguecircle2s referees demanded to take part voluntarily and they completed two questionnaires including Trait Anxiety (SCAT) and State Anxiety (CSAI-2) in three phases: the day before the game, before the game and after the game. Getting the number of crowds from the boss of the stadium and the supervisor of the matches, in the end of each game, we took the evaluation paper of each referee from the matchcircle2s superintendent and registered the mark. The analysis of data showed that the number of crowds does not have a meaningful relation with small scales of State Anxiety before and after game, but about the function is a meaningful negative relation. Also, there was a meaningful negative relation between function and cognitive anxiety and there was a meaningful positive Anxiety with self-confidence before the game. However, the experiencecircle2 referees with State Anxiety before the game show a meaningful negative relation.
