Endocrine and metabolic changes, as well as affective functions, were studied in eight healthy volunteers anticipating and executing a prearranged sequence of aerobatic flight. Control measurements were made at complete physical and mental rest. The following were determined: anxiety and hostility levels, blood glucose, cholesterol, triglyceride, plasma free fatty acids (FFA), serum thyroxine (T4), corticosteroids, prolactin, growth hormone, immunoreactive insulin and urinary excretion of VMA. The pattern of response was uniform in all subjects. Significant changes were seen in plasma FFA, corticosteroids, growth hormone and immunoreactive insulin following aerobatic flight. Anticipation of flight induced anxiety arousal and significant directional changes in plasma FFA, corticosteroids, as well as in VMA excretion. Hostility scores were highest immediately upon termination of flight.
