Impacts of sport sciences on the academic sport accomplishments were analysed at Saint Petersburg State University. Subject to the study were 35 issues of "The Matters of Academic Physical Education" dated 1964 to 2010 with study reports by the Saint Petersburg State University faculty, plus proceedings of the annual Research and Practical Conferences "Physical Education and Sports in the Academic Education System: Innovations and Prospects" for the period of 2011-2015. The authors applied the relevant mathematical (linear approximation by the least-squares method) and statistical (Spearman's range correlation) tools to obtain the publishing activity profiles of the staff trainers and instructors of the SPSU Physical Education and Sports Department; and the study data showed that the recent sag in the high-quality study reports and inflow of quasiscientific publications has been of direct negative impact on the competitive accomplishments of the picked Saint Petersburg State University teams trained by the authors of such publications.
