INTRODUCTION Physical exercise is an important tool to improve health or to treat many not communicable chronic diseases. AIM The aim was to evaluate the efficacy of a brisk walking program in order to reduce the common cardiovascular risk factor in a group of hypertensive-overweight patients. METHODS Twenty sedentary hypertensive-overweight patients (10 F and 10 M, aged 59.3± 7.1, height 163.5±10.0 cm, no beta blockers in drug therapy) were enrolled. 6 Minute Walking Test (6MWT) is easy to administer and reflective of activities of daily living. Bio impedance (BIA) is a method for hydration and body cellular assessment. At the beginning (T0) and after 3 months (T3) of exercise program 6MWT and BIA (Akern, Italy) were carried. Subjects were submitted to an individual home based exercise training consisting in fast walking at moderate effort: thirty minutes, three-four times a week. T-test were performed between T0 and aT3. RESULTS Anthropometrics parameters: reduction in body weight (T0: 77.9±16.6, T3: 76.2±15.8 kg; p<0.001) and BMI (T0: 29.2±6.8, T3: 27.4±4.4 kg/m2; p<0.001). BIA: improvement for phase angle (T0: 6.0±0.7; T3: 6.5±0.7°; p<0.05), resting metabolic rate (T0: 1578.3±182.4, T3: 1616.7±172.7 kcal; p<0.05), intracellular water (T0: 21.7±4.6, T3: 22.8±4.4 L; p<0.05) and body cellular mass (T0: 28.6±6.3, T3: 29.8±6.0 kg; p<0.05). 6 MWT: longer distance covered (T0: 567.3±66.7, T3: 599.12±81.4 m; p<0.05) and lower diastolic blood pressure immediately after 6MWT (T0: 75.3±7.8, T3: 70.9±5.8 mmhg; p<0.05). No significant differences were found in Heart Rate, Respiratory Rate, Systolic Blood Pressure and Self Perception of Effort. CONCLUSION A short period of regular aerobic exercise is suggestive for an early improvement for anthropometrics and functional parameters. Moderate aerobic exercise seems to be able to reduce the common cardiovascular risk factor in hypertensive-overweight subjects. 6MWT and BIA seem sensitive tests for the assessment in this population.
