The evaluation of cardiovascular response to exercise in healthy Turkish children

systolic and peak diastolic blood pressures (SBP max and DBP max ), change in systolic blood pressure (∆ SBP), and peak rate-pressure product (RPPmax) were positively correlated with age. There was no correlation between peak heart rate (HR max ) and age and there was also no significant increase in change in diastolic blood pressure (∆ DBP) with increasing age. The means ± SD values for ET, workload, HR max , ∆ HR, SBP max, DBP max, ∆ SBP, ∆DBP, and RPP max were 13.18±1.4 min, 8.56±0.93 MET, 171.46±1.91/min, 67.22±6.65/min, 125.16±13.36 mmHg, 73.32±4.06 mmHg, 24.3±5.96 mmHg, 7.2±6.9 mmHg, and 21504.7±2176.4, respectively. The values found in our study may be accepted as reference values of healthy Turkish children for exercise testing. The formula modified as (200-age) x 0.85 is thought to be more suitable to predict the target heart rate in children.
