This document summarizes a research article that examines the differences between two types of volunteers at major sporting events: regular sports volunteers affiliated with organized sports organizations, and first-time "pure event" volunteers without sports affiliations. It finds that regular sports volunteers tend to be older, male, have higher incomes, and are motivated more by intrinsic factors like sports interest and social motives. First-time volunteers tend to be younger, female, have lower incomes, and are motivated more by extrinsic factors like gaining qualifications and work experience. The study indicates these groups represent two different volunteer cultures - a traditional collective culture among regulars and a more modern reflexive culture among first-timers viewing events as opportunities for self-investment.
