The national sport community gives a high priority to the efforts to find new ergogenic agents to improve the physical work efficiency and rehabilitation processes. Objective of the study was to analyze variations of some bioenergy and physiology test rates obtained by the stepped work tests following a three-day fast. Experiments under the study were run at the Muscular Activity Bioenergy Research Laboratory of the N.I. Volkov Sports Biochemistry and Bioenergy Department at Russian State University of Physical Education, Sports, Youth and Tourism. Sampled for the experiment were 7 martial artists who were tested by the workload step test, with the oxygen consumption and exhaled carbon dioxide tested by CORTEX (Germany-based MetaLayser made) test system to produce the oxygen consumption rate; carbon dioxide exhale rate; respiratory ratio; ventilator equivalents of oxygen consumption and carbon dioxide exhale; heart rate tested by Polar (Finland made) heart rate monitor; and pre- and post- work (3/15min) lactate levels in the rehabilitation period tested by Doctor Lange Photometric system and standard tests. The study found the energy deficiency being of contradictory effects on the athletes’ energy supply systems. The athletes were tested with improved performance versus the pre-experimental test rates and improved efficiency associated with the growth of the relative oxygen consumption and anaerobic metabolism threshold.

Keywords: fasting, energy supply, maximal oxygen consumption, lactate, oxygen consumption, carbon dioxide, heart rate, respiration rate.
