<p>This study investigated the relationships among exercise passion, exercise emotion, and exercise adherence intention according to sport type in 230 sport club players. Based on the dualistic model of passion, exercise passion was divided into two types: harmonious or obsessive. Emotions were classified as either positive or negative. Participants were grouped by sport type: open-skill sports (e.g., tennis, basketball) and closed-skill sports (e.g., swimming, running). The results showed that harmonious passion significantly increased positive emotions in both groups, with a stronger effect in the open-skill sports. Obsessive passion only enhanced positive emotions in the closed-skill sports. Harmonious passion reduced negative emotions in both groups, particularly in the closed-skill sports, whereas obsessive passion increased negative emotions only in the open-skill sports. Both types of passion improved people’s intention to continue exercising, with positive emotions being the strongest predictor of exercise adherence intention. Notably, negative emotions also positively affected exercise adherence intention, but only in the open-skill group. These findings help people understand how different sports and passion types affect their emotional experiences and commitment to exercise, ultimately promoting long-term participation in sports.</p>
