Wrestlers, as well as athletes in other indoor and contact sports, came across numerous obstacles during the pandemic caused by the corona virus. Considering that no one had faced a situation like that one, the athletes, in this case the wrestlers, were provided with contrasting information that came from various sources. The athletes adopted certain attitudes and formed certain opinions based on that information. In accordance with those opinions, including the recommendations they were given, they displayed certain behaviours related to COVID-19. The objective of this research is to examine the differences in attitudes and behaviours resulting from the COVID-19 pandemic between the Croatian national wrestling team members and foreign national wrestling team members. The research included 116 wrestlers, 71 of whom were foreign and 45 Croatian national team members. The average age of the athletes is 22.86 years. The research was conducted using questionnaires that consisted of general questions and questions relating to recovery from and vaccination against COVID-19, including the COVID-19 Anxiety Scale which refers to the assessment of attitudes about the COVID-19 pandemic, and the COVID-19 Safety Behaviour Checklist comprising 7 questions concerning COVID-19-related behaviours. Based on the results of the research, it may be concluded that foreign and Croatian national team members have very similar attitudes about COVID-19. A statistically significant difference has been observed only in one variable. Foreign and Croatian national wrestling team members generally do not consider COVID-19 to be a disease considerably more dangerous than the flu, but a statistically significant difference has nevertheless been observed in that variable. A difference in a significantly larger number of variables may be observed when examining athletes’ behaviours resulting from their attitudes about COVID-19. Foreign wrestlers adhere to the recommended measures to a greater extent. The biggest differences in behaviours are manifested in the implementation of recommendations on maintaining better hand hygiene, keeping a safe distance, wearing protective masks, as well as on accepting the vaccine as one of the most important means of self-protection by the foreign national wrestling team members. It can be concluded that, despite having recovered from COVID-19 with milder symptoms or not having suffered from COVID-19 at all, most of the wrestlers involved in the research continue to adhere to the prescribed measures due to the sport they do and the physical contact they come into while doing it.
