Abstract
Our studies have shown increased systolic blood pressure(BP) reactivity to physical stress(exercise)in healthy black(B) children in comparison to healthy white(W) counterparts. We sought to determine the hemodynamic responses to another stressor, the psychologic challenge of 3 video pong games under increasingly demanding instructions. Heart rate (HR) and BP were measured in 170 healthy children(subjects). The HR delta values (maximal minus resting)were:
The delta values for both systolic and diastolic BP were similar to those shown for HR.
The race of the experimenter (BorW)was a critical variable in the respones;same-race experimenter-subject pairs had significantly greater reactivity than mixed-race pairs. Research into the mechanisms of essential hypertension must address the issue of experimenter race if both B and W subjects are studied.
