Difference between groups evaluated by two-way ANOVA;
a
p < 0.05 for the difference between boys and girls;
b
p < 0.05 for the difference between high RHR and normal RHR; RHR: resting heart rate; SD: standard deviation; kg: kilograms; cm: centimeters; BMI: body mass index; WC: waist circumference; SBP: systolic blood pressure; DBP: diastolic blood pressure; PP: pulse pressure.
