The purpose of this study was to determine whether racial differences exist in the @entity2494 ( @entity2494 ), @entity9027 ( @entity2990 ), and @entity701 concentrations of black and white postmenopausal @entity1 at rest and in response to submaximal exercise. Twenty-three postmenopausal @entity1 (13 white and 10 black) were studied on 2 occasions. On one occasion subjects rested quietly for 4 hours (control day), whereas on the other occasion after 50 minutes of rest, subjects exercised at 70% of Vo(2) peak for 30 minutes on a cycle ergometer (exercise day). Blood was sampled at rest, during exercise, and during recovery and assayed for @entity2494 , @entity2990 , and @entity701 concentrations. Resting @entity2494 and @entity701 concentrations and integrated area under the curve (AUC) were similar between the black and white @entity1 ; however, the black @entity1 had lower resting @entity2990 concentrations compared with the white @entity1 ( @entity2990 , black: 1.32 +/- 0.29 v white: 2.18 +/- 0.25 micromol. L(-1), P <.05). Regardless of race, @entity2494 and @entity701 AUC increased significantly above resting values (P <.01), but the exercise AUC for @entity2494 and @entity701 were not different between the black and white @entity1 ( @entity2494 : 607 +/- 133 and 824 +/- 108 min x nmol. L(-1); @entity701 : 9,604 +/- 1,247 and 8,076 +/- 1,093 min x nmol. L(-1), respectively). No exercise-induced change in integrated @entity2990 AUC was found in either group. In conclusion, racial differences exist in the resting @entity2990 levels of postmenopausal @entity1 , but with no racial differences in resting @entity2494 and @entity701 concentrations. Race had no impact on these adrenal hormone responses to submaximal exercise.
