Does physical activity reduce blood pressure and prevent hypertension in obese and lean subjects compared to diet or control?
Physical activity significantly lowers blood pressure independent of body mass index, though it is less effective than dietary interventions.
UNLABELLED: Physical activity in the prevention and treatment of hypertension in the obese. PURPOSE: The purpose of this paper was to assess the value of physical exercise in the prevention and treatment of hypertension with particular attention to possible interactions with relative weight. METHODS: We describe epidemiological studies and report meta-analyses of randomized intervention trials, i.e., randomized controlled trials on dynamic physical training and randomized comparative trials of exercise and diet. RESULTS: Epidemiological studies show an inverse relationship between physical activity or fitness and the incidence of hypertension, which was either independent of body size or more pronounced in the overweight. The weighted net reduction of blood pressure in response to dynamic physical training averages 3.4/2.4 mm Hg (P or = 30 kg x m(-2)) and attempt to resolve the blood pressure lowering mechanisms. CONCLUSION: Physical activity contributes to the control of blood pressure in overweight as well as in lean subjects.
