[Fat loading test: biochemical criteria and informative value of the physical endurance assessment].

Biochemical criteria of the fat loading test (FLT) were established and the search for interrelations between FLT biochemical variables and physiological parameters of dynamic physical testing (bicycle ergometry) was conducted in the experiment with participation of male volunteers. Relative gain in glucose, triglycerides, total cholesterol concentrations in blood, atherogenicity factor and insulin decrease after 3-hr FLT and reduction in blood concentrations of total cholesterol, insulin, hydrocortisone and testosterone after 9-hr FLT were ranked as reliable criteria. Rise in blood glucose and decrease in blood insulin after 3-hr FLT, and decrease in serum testosterone after 9-hr FLT were found to have prognostic value.

[Informational assets of glucose tolerance test in evaluation of endurance to psychoemotional stress].

Psychoemotional stresses were simulated in male volunteers in order to evaluate the predictive value of the glucose-tolerance test patterns. As was found, the predictive information is provided by the following parameters: Rafalsky and Boduen coefficients, glucose levels during 60-min testing, and the hypoinsulinemia coefficient. Operator's performance under the condition of time constraint is directly dependent on the insulin content.

[Biochemical evaluation of various respiration conditions during simulation of extended flight].

During a simulated long-term mission with participation of male volunteers biochemical effects of various conditions of oxygen supply including breathing the cabin air at 2.4 km, pure oxygen, and intermittent hypoxia/hyperoxia, i.e.
