  		Fig. 1. (A) NE at baseline ({blacksquare}) and during stress ({blacktriangleup}). Acute stress significantly increased NE in all subjects. NE release was significantly greater in SF soldiers (p < .05). (B) EPI at baseline ({blacksquare}) and during stress ({blacktriangleup}). Exposure to stress significantly increased EPI (p < .0001). No significant group differences were observed.
