XXXX and selected adrenal hormone responses to cognitive stress.

@entity1425 @entity26 @entity701 @entity1063 @entity65
Individuals manifesting high maximal @entity26 consumption (VO2max) have augmented adrenal responsivity to physical stress. We subjected 17 males representing a wide range of VO2max to cognitive stress and measured their forearm venous plasma @entity1425 , @entity1063 , and @entity701 responses. Six repeated blood samples were collected at resting, stress, and recovery intervals. Significant increases were observed for @entity1425 (X +/- SD; rest, 50 +/- 30; stress, 81 +/- 77 pg/ml; p less than or equal to 0.05) and @entity1063 (rest, 404 +/- 235; stress, 481 +/- 314 pg/ml; p less than or equal to 0.05). @entity701 changes were not significant. A positive association (r = 0.54; p less than or equal to 0.05) was observed between @entity1425 and VO2max during the first collection of the stress period. An inverse association (r = 0.49; p less than or equal to 0.05) was present between VO2max and @entity1063 . No significant correlations occurred with @entity701 . These results indicate that enhanced @entity65 is characterized by augmented @entity1425 responsivity to cognitive stress. This association exists in the presence of an inverse relationship between plasma free @entity1063 response and VO2max.
