Purpose: The purpose of this study is to compare stress and anger in A/B personality type individuals in relations to physical activity participation. Methods: A total of 276 undergraduate students responded to the FTA (Framinham A Type Behavior) tool and the Stress Response indicator (SRI), and the Korean version of the State-Trait Anger Expression Inventory (STAXI). Using physical activity stages of change questions, physical activity level was categorized. In order to find the varying levels of anger and stress across different physical activity participation, two-way ANOVAs were performed. Results: Personality type A individuals were found to have higher stress levels than personality type B individuals. Physical activity group showed lower levels of stress regardless of personality type. In addition, physical activity group had lower levels of anger across both type A and B personality types. A interaction effect was found on somatization. While personality type B individuals showed similar responses on somatization and trait anger across physical activity and non-physical activity groups, non-physical activity individuals with type A with had much higher somatization and trait anxiety compared to physical activity counterparts. Conclusion: Individuals with personality type A could reduce their stress and anger by exercising, resulting in lower risk for coronary artery disease.
