Abstract:

From post flight urine and blood samples, stress was appraised in two groups of pilots flying overwater missions of 6 hours duration in F-100 or F- 104 aircraft. Control determinations were made on a third group of pilots on an off-duty day. Urinary determinations included epinephrine, norepinephrine, corticosteroids 17-OHCS, sodium, potassium inorganic phosphate, urea, uric acid, and creatinine. Blood determinations included free and conjugated hydrocortisone and corticosterone-like fractions. Flying raised corticosteroid levels in plasma but not in urine. Levels for the F-100 group were higher than for the F-104. Urinary epinephrine and norepinephrine values for the flying groups were significantly above those for the control, values for the F-104 group exceeding those for the F-100. Differences in flying groups appear to relate to aircraft characteristics, weather conditions, and flying experience. Both flying groups showed high urinary excretion of urea and uric acid, but only in the F-104 group was sodium and potassium excretion elevated. Flying induced no variation in urinary phosphate. Singly and collectively, these determinations are basic to future studies on flight stress.
