Abstract
Prolactin, growth hormone and thyrotropsin (TSH) release during the stress of parachute jumping were evaluated in 14 male subjects. Subjects were studied at several times before and immediately after their first military parachute jump. All 3 hormones had risen significantly 1 to 14 min after the jump, compared to mean levels measured immediately beforehand. Earlier studies of physical exercise would suggest that emotional stress played a role in producing changes of this magnitude. Prolactin, TSH and growth hormone are released in physiologically significant amounts in association with the stress of parachute jumping.
