Introduction: Motivation is a key factor in human behaviour, driving us to take action and playing a crucial role in achieving goals. Achievement is based on setting and accomplishing goals. Brazilian jiu-jitsu (BJJ), a martial art that has become extremely popular, particularly in MMA, requires excellent physical fitness due to its challenging competitions. Understanding motivation and goal - setting is essential for success in this sport. Objective: To examine the relationship between achievement motivation and exercise addiction, exploring whether there are connections between the desire for success and exercise addiction, and determining the nature of this relationship, specifically whether a stronger desire for achievement is linked to a greater inclination for exercise among research participants. Methods: A sociodemographic questionnaire and validated psychological questionnaires were utilized. The research was conducted during the period from March 1, 2023, to May 1, 2023. Results: The study included 110 participants of different age groups and explored their tendencies toward goal achievement and exercise dependence. The results indicate a high inclination towards achievement and a strong dependence on exercise among the participants. Younger participants show a greater inclination towards achievement compared to older ones, while there is no difference based on gender, employment, place of residence, or education. Singles exhibit a higher desire for success. These findings provide valuable insights into motivation and behaviour related to goals and exercise. Conclusion: Research participants exhibit a strong desire for achievement and a high dependence on exercise. Furthermore, there is a positive correlation between the inclination for achievement and exercise dependence.
