With respect to the proportion of the theoretical and actual values of the cardiac output and the peripheral resistance 98 young healthy men were divided into three groups: 42 with the mixed type, 31 with the cardiac type and 25 with the vascular type of the circulation regulation. The environmental factors of a small size chamber gave rise to the changes that were the greatest in the subjects with the cardiac regulation and the least in the subjects with the mixed regulation. The subjects with the vascular type of regulation were those who showed varying tolerance to the environmental effects. It is suggested that the type of circulation regulation in the occupational selection as an indicator of the body tolerance to the environmental effects should be suggested.

[Individual health: essence, mechanisms, manifestations].

The paper provides evidence for that it is necessary to enhance the efficiency of prevention of chronic non-communicable diseases by applying the new strategy--the individual's health controlling strategy. To characterize the controlled object--individual health--its essence, mechanisms, and manifestations are considered. On this basis it is stated that a positive health scale can be constructed.

[Tolerance for controlled physical loading in chronic hypercapnia in man].

Young healthy test subjects showed adaptation to chronic hypercapnia during long-term exposure to an atmosphere containing 0.8--1.8% CO2 at normal atmospheric pressure: bradycardia, increase in vital lung capacity and chest movements, improvement of tests with breathing retention and further decrease in oxyhemoglobin. Simultaneously they exhibited an increase in the alkaline reserve of the blood and of the 2 min step-test index. This can be interpreted both as cause and effect: products of glycolysis are bound by buffer bases, thus reducing oxygen uptake per time unit. Study of adaptation to exercises of increasing workload demonstrated an earlier involvement of anaerobic mechanisms than under normal conditions: linear relationship between the workload and heart rate persisted only up to 150 beats/min. By the end of the second and the beginning of the third month of isolation the test subjects displayed deteriorated health state and work capacity in parallel with compensated acidosis.
