Changes in mood, fatigue, sleep, cognitive performance and stress hormones among instructors conducting stressful military captivity survival training

摘要: Abstract Numerous studies have examined the effects of captivity survival training on psychological and physiological function in trainees. In present study we shifted focus to instructors, measured that delivery exerts their levels stress performance. Because instructors are called upon perform difficult duties (e.g., mock interrogations) under extreme conditions, hypothesized significant increases indices would occur due training. addition, as part job tasking, conducted courses consecutive weeks. This offered a unique ecologically valid opportunity assess carryover from one week next. We be higher second than first Our hypothesis was supported: Delivering associated with impairments mood, fatigue, sleep, well reduction ratio testosterone/cortisol level blood. largely not supported 3-day break separating appeared sufficient for restoring function. results demonstrate although negative instructors' stress, recovery period is return baseline levels.
