Aim of the study: To statistically determine the extent to which overcoming the coronavirus disease and being in quarantine affected the physical condition of the subjects who had been exercising daily until then. Study design: A cross-sectional study. Participants and methods: The respondents are members of a professional folklore ensemble. An online anonymous survey questionnaire FormsApp, created by the author, was used for data collection, and consists of 22 questions. The respondents filled out the survey with their own consent. Fisher's exact test was used to test differences in categorical data. The statistical program MedCalc® Statistical Software version 20.100 (MedCalc Software Ltd, Ostend, Belgium; https://www.medcalc.org; 2022) was used for data analysis. Results: 36 subjects participated in the research, 17 of whom were over 40 years old. There was an equal number of female and male respondents. 29 subjects recovered from the coronavirus disease. During the quarantine period, all subjects were physically active, and aerobic activity was the most prevalent. They engaged in physical activity several times a week for 1 hour. When returning to group fitness and dance training, they noticed certain difficulties and obstacles, regardless of whether they had recovered from the coronavirus disease, and they believe that they were not physically ready enough to return. During the quarantine period, they kept the same number of kilograms as before. Conclusion: Getting over the coronavirus disease affects the return to performing group activities of artist dancers, but not significantly. The type and duration of exercise affect physical fitness, and the frequency of exercise does not affect the occurrence of physical injuries. The frequency of exercise among the ensemble members affected the increase in body mass.
