这项研究的目的是研究即将参与可能危及生命的事件的年轻男性的荷尔蒙和心理反应之间的关系。受试者被招募进行他们的第一次跳伞。与3-5天前从相同受试者获得的分数相比，在跳跃前的早上0800时，设计用于评估焦虑的问卷分数没有显著增加。然而，一个心理仪器的事件评级表明显着增加的强度，和交感神经系统的活动，唾液淀粉酶反应，增加了自我控制值。唾液皮质醇和睾酮水平显着低于早上的跳跃比自我控制值和控制受试者在同一时间确定的值。然而，血浆LH未受到抑制。在跳跃之前，焦虑和压力的测量以及事件的评级上升到很高的水平。除了睾酮，这仍然很低，血清皮质醇，催乳素，生长激素都大大增加后，心理措施的上升，达到峰值前或着陆后不久，并在接下来的一个小时内显着下降。降落后15 min内，焦虑和主观应激评分下降至自我控制值，但事件量表评分仍显著升高。总之，报告的焦虑与纯粹的心理应激源被抑制，直到几个小时内的事件之前，但之前的交感神经系统活动的增加和抑制血浆皮质醇和唾液睾酮水平。事件本身与皮质醇下降的逆转有关;其他与压力相关的激素增加，但唾液睾酮仍然很低。
The purpose of the study was to examine the relationship between the hormonal and psychological responses of young men about to engage in a potentially life-threatening event. Subjects were recruited to take their first skydiving jump. The scores on questionnaires designed to assess anxiety were not significantly increased at 0800 h on the morning before the jump by comparison with scores obtained from the same subjects 3-5 days previously. However, a psychological instrument for rating of events indicated significantly increased intensity, and sympathetic nervous system activity, as measured by the salivary amylase response, was increased over self-control values. Salivary cortisol and testosterone levels were significantly lower on the morning of the jump than self-control values and values in control subjects determined at the same time of day. However, plasma LH was not suppressed. The anxiety and stress measures as well as the rating of events rose to high levels just before the jump. With the exception of testosterone, which remained low, serum cortisol, PRL, and GH all increased greatly subsequent to the rise in psychological measures, reached peak values before or shortly after landing, and declined significantly within the next hour. Anxiety and subjective stress scores declined to those of the self-control values within 15 min after landing, but the rating of events scale remained significantly elevated. In summary, reported anxiety associated with a purely psychological stressor was suppressed until within a few hours preceding the event, but was preceded by an increase in sympathetic nervous system activity and suppression of plasma cortisol and salivary testosterone levels. The event itself was associated with a reversal of the cortisol decline; other stress-associated hormones increased, but salivary testosterone remained low.
