Impact of Physical Activity Interventions on Blood Pressure in Brazilian Populations

Abstract

BackgroundHigh blood pressure is associated with cardiovascular disease, which is the leading cause of mortality in the Brazilian population. Lifestyle changes, including physical activity, are important for lowering blood pressure levels and decreasing the costs associated with outcomes.ObjectiveAssess the impact of physical activity interventions on blood pressure in Brazilian individuals.MethodsMeta-analysis and systematic review of studies published until May 2014, retrieved from several health sciences databases. Seven studies with 493 participants were included. The analysis included parallel studies of physical activity interventions in adult populations in Brazil with a description of blood pressure (mmHg) before and after the intervention in the control and intervention groups.ResultsOf 390 retrieved studies, eight matched the proposed inclusion criteria for the systematic review and seven randomized clinical trials were included in the meta-analysis. Physical activity interventions included aerobic and resistance exercises. There was a reduction of -10.09 (95% CI: -18.76 to -1.43 mmHg) in the systolic and -7.47 (95% CI: -11.30 to -3.63 mmHg) in the diastolic blood pressure.ConclusionsAvailable evidence on the effects of physical activity on blood pressure in the Brazilian population shows a homogeneous and significant effect at both systolic and diastolic blood pressures. However, the strength of the included studies was low and the methodological quality was also low and/or regular. Larger studies with more rigorous methodology are necessary to build robust evidence.

Persistent effect at 30-month post intervention of a community-based randomized trial of KM2H2 in reducing stroke and heart attack among senior hypertensive patients

“…Receiving the KM2H 2 was associated with 3.02 mmHg and 1.60 mmHg reductions in the systolic and diastolic blood pressure, respectively while the reductions in blood pressure were not statistically significant. This appears to be inconsistent with other physical activity intervention program that showed a significant effect of physical activity on reducing elevated blood pressures [ 38 – 40 ]. A possible reason is that the majority of published studies were conducted among adolescents and adults while the participants of our study were senior hypertensive patients.…”

Prevalence and associated factors of uncontrolled hypertension among hypertensive patients: a nation-wide survey in Thailand

“…As a result, the patients with hypertension in this area are agriculturists; moreover, traditional dancing and playing of northeastern Thai games creates more physical activities. More physical activities can decrease both systolic and diastolic BP including decreased risks for high BP [22, 23]. Our study has shown that hypertensive patients receiving medical treatment at middle level hospitals and standard/advanced level hospitals tended to indicate a higher prevalence of uncontrolled hypertension compared with those at first level hospitals.…”

Does Caffeine Supplementation Associated with Paralympic Powerlifting Training Interfere with Hemodynamic Indicators?

“…Although some studies have shown evidence of the effects of physical activity on blood pressure [ 53 , 54 ], the use of supplements and caffeinated beverages on the cardiovascular response to exercise has been widely studied. Thus, Systolic Blood Pressure tends to increase during exercise with caffeine consumption [ 55 ].…”
