The authors investigated whether an altitude of 1,350 m would affect the rat cardiovascular system in the same way as genuine altitude hypoxia and the way it would take effect when combined with endurance training in the form of swimming It was found that 8 weeks spent at this altitude led to an increase in absolute and relative heart weight, to right ventricular hypertrophy, and to increased resistance of the myocardium to acute anoxia. Physical training at a moderate altitude resulted in an increase in the relative weight of the musculature of both the right and the left ventricle and of the septum. Unlike low altitude training, however, growth of the two compartments of the heart was proportional. The resistance of the myocardium of trained animals against anoxia was the same, irrespective of whether they trained at a low or a high altitude. The results show that even a moderate altitude is not a matter of indifference for the rat organism, but that it leads to characteristic manifestations of altitude hypoxia in the cardiovascular system.
