ABSTRACT To determine whether responses to dynamic exercise differed between healthy black and white children, we tested 220 white and 182 black children between the ages of 6 and 15 on a
cycle ergometer. We analyzed the following variables in relation to race, sex, age, and body surface area: resting systolic blood pressure (SBP); maximum (max) SBP; resting heart rate (HR);
HR max. Among the boys, there were no consistent differences between black and white children for resting HR, HR max, or resting SBP. The BP max values were statistically significantly
higher in black males in seven of the ten age groups (6,8,9,10, 11,12, and 13 years). When analyzed by surface area, all groups of black males had higher BPmax. Among the girls, no
consistent differences were seen for HRmax, and resting BP. Resting HR was lower in the 9 and 10 year old blacks; it was lower in all body surface area groups. BPmax was higher in the 9 and
10 year old blacks; it was higher in blacks over 1.05m2. These data suggest that black males have increased peripheral vascular resistance in comparison to their age-matched or surface-area
matched white counterparts. The black girls tested may have been more fit (as reflected by decreased resting HR) but still had higher BPmax than white girls. This suggests that possible
precursors for the early onset of hypertension in the black population may be demonstrated as early as six years of age. ARTICLE PDF AUTHOR INFORMATION AUTHORS AND AFFILIATIONS * (Spon by
