title: [Adaptation to hypoxia as a factor enhancing work capacity].
abstract: The results of applying N. N. Sirotinin's concept of the use of hypoxic adaptation to enhance working capacity are given. There is evidence for the efficiency of adaptation of trotters to two hypoxias: to hypoxic hypoxia (in the midmountains) and to exercise hypoxia (during interval training under the conditions of Moscow) for increasing their performance. These studies demonstrated that in the midmountains, the trotters had more infrequent respiration, increased respiratory and minute respiratory volumes which were more obvious by the end of a monthly mountain stay. The monthly training of trotters significantly altered hemoglobin levels and erythrocyte counts. Correction of the respiratory system via adaptation to decreased p1O2 improved good time in trotters: the speed increased by 0.41 versus by 0.18 m/sec in the controls. The average record of experimental horses significantly increased and was equal to 2 min 09.7 sec for a 1600-m distance while the control horses had 2 min 11.1 sec. The use of interval exercises during training produced positive changes in the systems of expiratory respiration, blood flow, blood, tissue metabolism. Blood oxygen transport function improved in trotters after interval training. This training markedly improves the fast qualities in trotters.
