Purpose: This paper aims to investigate capitalization support, an alternative perspective for theorizing social support in-service settings. In the service setting of the student-athlete experience, the relationships between capitalization support service dimensions (i.e. the academic, athletic, self-development and place dimensions), well-being and sports performance are examined through a transformative sport service research (TSSR) lens, a newly introduced form of transformative service research (TSR). Design/methodology/approach: Data from an online survey of Australian student-athletes (n = 867) is examined using partial least squares structural equation modeling. Findings: The results support the theorized service dimensions of capitalization support, indicating their validity and relevance to the student-athlete experience. Further, the results demonstrate that all capitalization support dimensions except athletic support (i.e. academic support, place support and self-development support), have a direct effect on well-being and an indirect effect on sports performance. Originality/value: This research is unique for several reasons. First, it introduces a new perspective, capitalization support, to theorizing about social support in services. Second, it is one of the first studies in both TSR and TSSR to empirically test and demonstrate a relationship between support services, well-being and performance in a single study. Insight into how to design services to optimize well-being in relation to other service objectives like performance thus emerges.
