[The effect of moderate altitude on the maintenance of a good health status and high physical work capacity in cosmonauts over the course of a long period of time].

The development of the methods to maintain good health and high performance and occupational longevity of cosmonauts is an urgent problem. For this end, an effect of periodic (1-2 times a year) training in mid-lands on working and functional capacities of cosmonauts being members of cosmonauts corps for extended periods of time (20 years) was studied; the results of 40 trainings in mid-lands at 1,600 to 2,400 m above sea level are summarized. Before, during and after training, the physiological and physical parameters of the body (BP after Korotkoff, HR, VO2max) during exercise bicycle ergometer tests as well as the time of running on treadmill at a rate of 4.
