This study aimed to clarify the characteristics of experiences in athletic club and life skills of college baseball club members with national level competitive abilities. First, with regard to experiences in athletic club and life skills, we conducted the characteristics of the entire subjects in this study. Subsequently, we examined the differences in experiences and life skills based on differences in competitive abilities. We also analyzed the relation of athletic club experiences on life skills. We conducted a questionnaire survey that targeted 379 members of college baseball clubs, and analyzed the data of 301 members. As a result, college baseball club members generally scored high on support from others for sports club activities and etiquette and manners for life skills. On the other hand, the score of setting goals for life skills was low. The roster players who are registered as members in the official game tended to have higher scores for self-disclosure than the backup players. Furthermore, the roster players also scored higher on life skills, setting goals, thinking carefully, being humble, and maintaining physical health and well-being. Finally, while experiences in relation to support from others as well as effort and endurance had a positive influence on many life skills, the experience of daily life guidance from leaders had a negative influence on some life skills.
