[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.
