Oxford Dictionary defines centralization as "The action or fact of decentralizing; decentralized condition" (Oxford Dictionary). Decentralization and sport are closely linked in determining places and spaces within our territories. The rapid urbanization and redevelopment of industrialized arrondissements have introduced a considerable increase in sporting spaces and public playgrounds within our areas. The management and coordination of these new forms of entertainment have opened up new possibilities for local communities concerning urban sports spaces. Moreover, the decentralization of processes implies the reconsideration of local autonomies, resources and citizenship concerning participation and sharing in the planning of territories, considering sports urbanism. After the COVID-19 pandemic, we observed new collaborative and participatory projects to redefine specific urban spaces in cities and metropolises. To date, decentralization is a theoretical basis for cities that proposes essential elements for designing sports spaces in urban or rural areas. Given the new forms of participation and collaboration, decentralization has acquired an increasingly significant and central role in the design and management of our cities of the future.
