OBJECTIVE: To verify the effects of a six-month non-supervised physical training program followed via the Internet on blood pressure and body composition in normotensive and borderline hypertensive individuals. METHODS: One hundred and thirty five individuals were divided into two groups: 1) normotensive individual (n = 57), 43 ± 1 years of age, systolic blood pressure (SBP) < 120 and diastolic blood pressure (DBP) < 80 mmHg (GI); and 2) borderline hypertensive individual (n = 78), 46 ± 1 years of age, SBP 120 to 139 and DBP 80 to 89 mmHg (GII). RESULTS: After a three and six-month physical training, GII individuals showed a significant reduction in SBP (-3.6 ± 0.94 and -10 ± 0.94 mmHg, p < 0.05, respectively) and PAD (-6.5 ± 1 and -7.1 ± 0.9 mmHg, p < 0.05, respectively), body weight (-1.12 ± 0.26 and -1.25 ± 0.31 kg, p < 0.05, respectively), BMI (-0.79 ± 0.4 and -0.84 ± 0.41 kg/m², p < 0.05, respectively) and waist circumference (-1.12 ± 0.53 and -1.84 ± 0.56 cm, p < 0.05, respectively). In the GI group, the physical training led to a decrease in waist circumference at the sixth month (-1.6 ± 0.63 cm, p < 0.05). CONCLUSION: This program decreases blood pressure, body weight, BMI, and waist circumference in borderline hypertensive individuals, and is therefore a safe and low-cost strategy in the prevention of cardiovascular diseases and improvement of health status of the population.
