Physical capacity evaluated by the exercise stress test (modified Bruce protocol).

	Baseline	After-training
Test duration (min)	9.29±2.90	11.41±2.22*
Distance walked (m)	551±92	630±153*
VO2 max (ml/kg/min)	24±7	28±9*
HR max (bpm)	141±14	146±13
SBP max (mmHg)	171±20	179±21
Double product (mmHg.bpm)	24,201±4,352	26,202±3,552
Work load (METs)	7.2±1.7	8.5±3.0*

VO₂ max – maximum oxygen consumption; HR max – maximum heart rate reached; bpm – beats per minute; SBP max – maximum systolic blood pressure reached; MET – metabolic equivalent rate;
