Efeitos de um programa de exercícios físicos sobre a pressão arterial e medidas antropométricas

Abstract

Introduction: The number of overweight people or obesity has reached alarming levels in Brazil. Nonmedi-camentous conducts should be the initial strategy for the treatment of individuals with overweight and light to moderate hypertension. Objective: To analyze the effects of a physical training program for a period of 24 months on body composition and blood pressure in normotensive and prehypertensive individuals. Methods: The study included 35 subjects randomized: (GI) normotensive (n = 16), 51 ± 1 years, systolic blood pressure (SBP) <120 and diastolic (DBP) <80 mmHg, and (GII) pre-hypertensive (n = 19), 54 ± 1 years, SBP 139 and DBP 89 mmHg. Results: After 24 months of a physical training program,the individuals from GII showed a reduction in SBP (-3,6 ± 0,94 e -10 ± 0,94 mmHg, p <0.05, respectively) and DBP (-6.5 -7.1 ± 1 and ± 0.9 mmHg, p <0 05). In both groups there was a reduction in waist circumference (-1.74 ± 3.5 and -1.91 ± 4 cm, p <0.05) and adiposity index (-1.21 ± 2.6 and -1, 35 ± 3.1%, p <0.05) increase in body mass (+1.27 and +1.32 ± 3 ± 3.8 kg, p <0.05), BMI (+0.72 ± 0.4 and +0.54 ± 0.60 kg/m2, p <0.05) and fat-free body mass (+0.91 ± 0.5 and +0.77 ± 4.8 kg p <0.05). Conclusion: This program reduced B P, waist circumference and adiposity index in hypertensive individuals, thus constituting, in a safe and cost-effective strategy in the prevention of cardiovascular disease and improving the health status of the population.
