Abstract: | Hormonal regulation of metabolism was investigated in test subjects of three age groups: group 1 included test subjects of 41-50 years old, group 2 test subjects of 50-57 years old, and group 3 test subjects of 26-33 years old. Test subjects from groups 1 and 2 were exposed to head down tilt (-8 degrees) as well as linear acceleration of 3 GZ for 1 min and exercises of 450-1050 kgm before and after the tilt test. Group 3 test subjects were exposed to neuro-emotional stress before, during and after the head-down test. Exposure to head-down tilt, acceleration and exercises caused adaptive changes in humoral regulation of metabolism in the test subjects of groups 1 and 2. Food supplements given to group 3 test subjects produced a normalizing effect on humoral regulation of metabolism. |
