There established a situation in sport science when, on the one hand, athletes are known to have reserves to optimize their physical working capacity and on the other hand - the complete lack of knowledge on the ways of determination and use of additional reserves of human abilities. Martial arts are usually considered sports, where the principle role belongs to physical training of athletes. Numerous researches of physiological functions of judokas, pedagogical observations within the educational and training process and competitive practice confirm the fact that high level of functional efficiency is the key factor in efficient realization of technical and tactical actions in the competitive environment. The purpose of the study was to analyze the influence of interval run on development of the aerobic-anaerobic working capacity of judokas. The influence of loading in the form of interval run was defined by means analysis of change of the percentage ratio of heart rate during the whole training process. The work revealed the data characterizing changes in the respiratory system of athletes, which are adduced in the paper. The introduction of interval run to the training provoked insufficient decline of the indices of forced expiratory spirogram and expiratory muscle strength by 2-3 % with the inspiratory muscle strength remained unchanged pulmonary power and airway conductance declined by 20 and 15% respectively, a maximal pulmonary ventilation improved by 9,2%. Development of the aerobic-anaerobic component of endurance by means of interval run in judo represents the loading of below 170 bpm of the mean heart rate with blood lactate rising up to 6,9 mmol/I, resulting in decrease of airway conductance and pulmonary power and increase of the maximal pulmonary ventilation by 9,2%.
