Characteristics of the study population.

	Active group (n = 24)	Controls (n = 24)	value
Age (years)	15.5 (13–19)	15.4 (13–19)	0.934
BSA (m^2)	1.69 (1.37–1.98)	1.72 (1.26–2.23)	0.578
SBP (mmHg)	120 (105–155)	115 (105–130)	0.449
DBP (mmHg)	65 (50–85)	65 (55–80)	0.610
HR at rest (beats/min)	62 (42–85)	69 (49–88)	0.029
Peak VO2 (mL/kg/min)	62 (53–79)	44 (27–62)	<0.001

Data are presented as median with range (min-max). Bold styling denotes statistical significance. BSA, body surface area; SBP and DBP, systolic and diastolic blood pressure; HR, heart rate; VO₂, oxygen uptake.
