 | We examined predictors of peritraumatic dissociative states (PDS) and quantified the link between PDS and the subsequent psychological impact of stressful events during extreme military stress. A regression model examining biological predictors of dissociative states indicated that sympathetic cardiac modulation during sleep accounted for 9.6% of the variance in PDS. In a second regression model examining behavioral predictors of PDS, perceived stress and coping styles combined to account for 47.2% ... |

| A useful approach to quantifying factors that influence human performance involves the classification and comparison of so-called elite and non-elite performers. In this pilot study, the authors classified 6 graduates of the Basic Underwater Demolition/SEAL training program as elite and compared them to 6 age-matched non-elite military personnel on key aspects of physiological and psychological function during free living and in response to intense military stress. Participants completed measures of ... |

| Little is known of individual differences governing human responses to realistic stress. In this study, the authors examined the relationships of anger experience and expression to psychophysiological stress indices during daily living and in response to military survival training in 45 healthy, male, active-duty Navy personnel. Prior to participation in survival training, participants completed self-report measures of perceived stress and anger. Also, salivary cortisol and dehydroepiandrosterone sulfate (DHEAS) were assessed ... |

| Accumulating evidence suggests that negative affect is associated with elevated cortisol. Limited research has investigated this association in young, highly functioning, and stress-resilient populations. Methods: 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). Salivary cortisol was assessed at five time points over ... |

| We examined the responsiveness of both cortisol and dehydroepiandrosterone sulfate (DHEAS) to the stress of survival training in military men and evaluated relationships to performance, peritraumatic dissociation, and the subsequent impact of stressful events. |

|
| Physical fitness and physical conditioning have long been valued by the military for their roles in enhancing mission-specific performance and reducing risk of injury in the warfighter. It is not known whether physical fitness plays a causal role in attenuating acute military stress reactions or the evolution of post-traumatic stress disorder. Objective: The objective of this study was to determine whether physical fitness influences the impact of stressful events during ... |
