Abstract:

The glucose analogue 2-deoxy-D-glucose 2-DG was used as a means of producing intracellular hypoglycemia in eight normal male volunteer subjects during a control period, immediately following their initial exposure to acceleration acute acceleration and following their initial exposure to acceleration acute acceleration and following a fourth acceleration exposure chronic acceleration. Plasma glucose, free fatty acids, serum immunoreactive growth hormone, plasma cortisol, and urinary epinephrine and norepinephrine were measured prior to and following the infusions of 2-DG. There were significant depressions in glucose, urinary epinephrine, cortisol and free fatty acids following acceleration that were not seen when compared to basal, unprovoked levels. Even with the modest acceleration stresses used in this study, discernible changes in gluco-regulatory hormone reserves were uncovered.
