This study aimed to investigate the effects of perceived quality of sporting event and perceived organizational support (POS) on volunteers' leisure satisfaction with their volunteering experience and the effect of volunteers' leisure satisfaction on their civic participation attitudes and future volunteering intention and to examine differences in first-time and experienced sport event volunteers in the relationships between the study's variables. Data were collected from 709 volunteers at the 2020 Super Bowl. Results showed that volunteers' perceived event quality and POS predicted their six leisure satisfaction dimensions (i.e., psychological, educational, social, relaxation, physiological, and esthetic). Educational and social dimensions influenced volunteers' civic participation while psychological and social affected their intention to continue volunteering. The results also revealed significant differences between first-time volunteers and experienced volunteers in the effect of POS on esthetic, educational, psychological, and social dimensions. The findings offer insights into how volunteer management practices can address volunteers' leisure satisfaction.
