Total cortisol concentrations were similar between men reporting high or low anxiety during free-living conditions (8.6 +/- 3.2 vs. Trait anxiety was measured with the trait portion of the Spielberger State-Trait Anxiety Inventory 1-3 wk prior to the military exercise. Salivary cortisol was assessed at five time points over 2 consecutive days of free-living measurement, and three time points during a stressful military experience. We examined the relation of trait anxiety with total and diurnal salivary cortisol during free-living conditions and during a stressful military exercise in 26 military men ages 19-30 yr (M = 21.6, SD = 2.3). Limited research has investigated this association in young, highly functioning, and stress-resilient populations. It is suggested that taking action under stressful conditions, as opposed to remaining passive, is a powerful coping tool.Īccumulating evidence suggests that negative affect is associated with elevated cortisol. The adaptive potential of activity in stressful situations is discussed in terms of: the sense of mastery and control provided by activity activity as a means of attention diversion and activity as a means of discharging energy generated by mobilization. To achieve a better understanding of the effect of activity on stress reactions, several distinctions are made: between various types of stress reactions between various indices and measurements of stress reactions between activity which is directly related to the source of threat and activity which is not and between various personality dimensions. The studies reviewed were conducted mainly in real-life situations and involved diverse forms of coping activities under various conditions of danger and distress. This paper is an analytical review of studies comparing stress reactions in threatening situations during which the person can or cannot take action. Trois hypothèses découlent de ces observations: l'amplitude des réactions physiologiques du coronarien au stress est faible soit parce qu'il inhibe ses réactions, soit parce qu'il s'est adapté à un niveau de stress qui chez lui est constamment élevé, soit parce que son organisme est déficient. Or, une élévation des premiers paramétres traduit une bonne préparation à l'action l'élévation des seconds traduit, par contre, un épuisement de l'organisme. Par contre, un second lot de paramètres (consommation d'O2, rejet de CO2, quotient respiratoire, équivalent respiratoire, pouls d'O2) différencient mieux les coronariens stressés des coronariens non stressés que les normaux stressés des normaux non stressés. Un premier lot de paramètres (tensions systolique et diastolique, fréquence cardiaque et respiratoire, volume ventilé, variables biologiques) différencient mieux les normaux stressés des normaux non stressés que les coronariens stressés des coronariens non stressés. La tension styolique et diastolique, l'ECG, certaines measures respiratoires et biologiques ont été enregistrées. L'échantillon a été divisé en 40 coronariens (20 stressés et 20 non stressés) et 40 normaux (20 stressés et 20 non stressés) de manière à pouvoir différencier les effets du stress sur les réactions physiologiques de coronariens et normaux, et les effets de la maladie coronarienne sur les réactions physiologiques de sujets stressés et non stressés. Implications for military aviator training and other domains of aviation are discussed.Ĭette étude compare les réactions physiologiques au stress de 80 sujets soumis à un effort mental et physique. These two factors were found to influence each other in addition to impacting the saliency of certain cues and factors for the aviators. ![]() Through this method, two contextual factors in the military aviation environment not previously addressed were identified: (a) the purpose of the flight and (b) the flight operation environment. This study addresses these shortcomings by using in-depth interviews of critical incidents guided by the critical decision method to gain a deeper understanding of the decision making process of experienced naval aviators during novel or unexpected situations in flight. This research has also been limited by its lack of realism and/or inability to probe aviators for additional clarifying information relevant to their decisions. ![]() ![]() ![]() Aeronautical decision making research has focused almost exclusively on general and commercial aviation - with little attention given to the military aviation domain.
