The participants of the study, which was conducted using the causal comparison model, consisted of 100 people aged 18 years and over who exercised regularly, selected by purposive sampling method, and the sedentary group consisted of 100 people aged 18 years and over who had no exercise history, selected by random sampling method. Personal information form, Beck Anxiety Inventory and State-Trait Anxiety Inventory were used in the study. The findings of the study show that there is a significant difference between the anxiety levels of regular exercisers and sedentary individuals. Another result of the study is that there is a significant negative relationship between both anxiety and state anxiety levels and psychological flexibility levels of participants who exercise regularly. In addition, it was determined that the total scores of the Psychological Flexibility Scale predicted the Beck Anxiety Scale and State Anxiety Inventory scores statistically significantly and negatively in individuals who exercised regularly. As a result, it can be said that regular exercise may positively affect psychological flexibility and may be a factor that reduces both state and general anxiety levels.
