Bаsed оn the fоllоwing reseаrch summаry, which theoretical framework did the researchers use to guide their study? Football is often recognized for its competitive nature, but it also plays an important role in shaping relationships and communities. This study investigates how participation in football contributes to the development of social capital by fostering cooperation, strengthening social networks, and encouraging personal growth among players. Guided by Social Action Theory and Social Network Theory, the researchers sought to describe how interactions on and off the field influence the formation of trust, teamwork, and shared values. To answer these questions, the researchers observed football teams throughout a competitive season, interviewed players and coaches about their experiences, and examined organizational documents related to team culture and participation. Information gathered from these sources was compared to identify common patterns in communication, social interaction, and the development of relationships within teams. The findings suggest that football provides an environment where individuals develop stronger social connections, learn to work collaboratively, and build qualities such as trust, responsibility, and mutual support. These experiences not only benefit individual participants but also strengthen the broader communities in which teams are embedded. Overall, the study demonstrates that football functions as more than a sport—it also serves as an important setting for building social capital and promoting positive social development.
