Abstract:

The fluorescence method of Sweat for the determination of hydrocortisone and a corticosteronelike fraction in blood was utilized in an attempt to evaluate flying fatigue in a group of 44 aircrewmen participating in flying activities in military aircraft. Preflight values for each of the two steroid fractions agreed with those of Sweat for normal male subjects, but significant increases in both fractions were noted after flights of 9 to 12 hours duration. These changes are not of the nature of normal diurnal variations.
