HUMAN BIOCHEMICAL PARAMETERS OF ACCELERATIVE STRESS.
Abstract
Acceleration stress conditions were imposed on four healthy subjects riding the human centrifuge. Blood biochemical analyses were performed on all subjects, with the demonstration of an increase in blood glucose following centrifugation in three of the four subjects, two of whom developed 'blackout'. All four subjects developed 'greyout'. The changes in blood sugar may suggest a relationship between epinephrine secretion and graduated acceleration stress resulting in physiological changes in the subject. Changes in pooled plasma phospholipid fractions were demonstrated in blood samples obtained before and following acceleration; these changes suggest that acceleration may interfere with intracellular energy transfer mechanisms involving phosphorylated compounds associated with oxidative metabolism. The preliminary results of the pilot project indicate that further biochemical measurements may be desirable in assessing acceleration tolerance in man. (Author)
