Medical Aspects of Athlete Endurance. / Collected works of the Functional Diagnostics Sector. Edited by R. D. Dibner. Committee for Physical Culture and Sport under the Council of Ministers of the RSFSR.

128 pp. ; 22 cm. Hardcover. Edition of 1,000 copies. In Russian.

This 1971 specialized scientific collection is a significant document from the "Golden Era" of Soviet sports medicine, stemming from the prestigious Leningrad Research Institute of Physical Culture. Edited by Regina Dibner, a leading expert in sports cardiology, the text provides a deep dive into the internal logic of human physical limits, including the arrangement of cardiovascular and respiratory adaptations during prolonged exertion. At a time when the Soviet Union was refining its dominance in international endurance sports—such as long-distance running, cross-country skiing, and cycling—this volume presents empirical data on the functional diagnostics used to monitor and enhance elite athlete performance.
The 128-page volume explores various physiological markers of endurance, the effects of overtraining on the heart, and the development of diagnostic criteria for assessing an athlete's "readiness" for peak competition. Published by the Leningrad Research Institute of Physical Culture (LNIIFK) in a sturdy 22 cm hardcover format, the book was intended for a narrow circle of sports physicians and high-level coaches. Due to its highly technical nature and a very limited print run of only 1,000 copies, this 1971 Leningrad imprint is a significant rarity. For bibliophiles, historians of medicine, and collectors of sports science literature, it is a vital primary source, documenting the rigorous scientific foundations that underpinned the success of the Soviet athletic machine during the Cold War.
