The legacy of a sport event refers to the wide-ranging, long-term impacts-both intended and unintended, positive and negative-that a sport event leaves behind after its conclusion. These effects can influence various dimensions of the host city, region, or country and may persist for years or even decades beyond the event itself. It includes social, cultural, environmental, political, technological, and sporting outcomes that result from hosting the event. These legacies can be tangible (such as newly built stadiums, improved transportation systems, or enhanced tourism appeal) or intangible (such as increased civic pride, international visibility, policy reform, or the promotion of physical activity among the population).
A sport event's legacy may be planned-as part of a strategic vision by organizers and stakeholders-or unplanned, emerging naturally from the dynamics of the event and its interaction with the local context.
