The article analyzes the activities of fizcors (physical culture correspondents) as a component and, at the same time, a rather specific part of the movement of rabsel-cors (working-class and rural correspondents) common to the Soviet press of the 1920s - 1930s. The work draws attention to the fact that both the Rabselcor move- men! and the physical culture movement equally served the goals of the Soviet government to foster and direct the activity of the masses into the framework that it needed. On the basis of archival documents stored in the State Archive of the Russian Federation and not previously put into active scientific circulation and using the materials of non-periodicals and periodicals of the second half of the 1920s - early 1930s, the author of the article considers how the main areas of activity, attitudes and goals of the Rabselcor movement were refracted in the sports sphere, what features distinguished fizcors' activities. Special attention is paid to the study of organizational work carried out by editors of magazines and newspapers with freelance authors, in particular, instructional materials published on the pages of periodicals and as separate publications. We consider them as one of the first attempts in the history of sports journalism to provide the wide range of volunteer sports press assistants with the basics of knowledge necessary for the preparation of newspaper materials.
