Abstract: Intensive urbanization and the demographic growth of cities, combined with the increasing complexity of the labor application system and the rising demand for accessible sports facilities, make the problem of developing sports infrastructure at labor application sites relevant. The subject of the study is the spatial-territorial and functional location and nature of sports infrastructure at large industrial enterprises in Leningrad, aimed at determining the spatial relationship of sports infrastructure with labor application sites. An evolutionary analysis of the structural and spatial patterns of sports infrastructure placement in relation to its development within the structure of the industrial complex and the overall urban structure, starting from the 1920s to the present day, has been conducted to identify the general issues concerning the use of sports facilities in production under the current conditions of urban development in Saint Petersburg. For the analysis of structural and spatial patterns of sports in relation to its urban planning placement within the industrial complex from the 1920s to the 1980s, urban planning documents on the development of Leningrad, mapping and reference documents on sports infrastructure, and the development of Leningrad's industry and the specific factories examined in the study were utilized. The novelty of the research results lies in tracking changes in the nature and role of sports facilities and their territorial accessibility to enterprises (the main places of labor application). As a result of the study, the stages of development of sports infrastructure at enterprises were identified using the example of five Leningrad factories, and the issues regarding their placement in the context of modern development in Petersburg were defined. Conclusions were drawn about the loss of spatial correspondence between elements of sports infrastructure and the planning placement of enterprises, as centers of labor application, within the structure of the city. The developed state of sports infrastructure at enterprises has been determined as focused objects of specialized sports, along with the factors that defined this development: uneven distribution of labor resources within the overall system of labor application in the city; intensive development of residential areas and a decreasing number of working enterprises; and the close interconnection between the nature and quantity of sports facilities with the sports organizations of enterprises.
