  • Values are mean±SD.

  • *Heart rate max is the maximum heart rate during 10 min of standing.

  • †δ Heart rate is the increased heart rate during the active standing test.

  • ‡δ SBP is the increased SBP during the active standing test.

  • §δ DBP is the increased DBP during the active standing test.

  • ¶p<0.001, vs 6–12 years.

  • DBP, diastolic blood pressure; SBP, systolic blood pressure.
