“…Men and women with an increased systolic BP seem to benefit slightly more from enhanced leisure time in contrast to those with a normal systolic BP. These findings are in accordance with other studies reporting that high levels of physical activity or aerobic exercise may protect against the adverse effects of elevated systolic BP [29,30].…”

International audienceFew studies have investigated the independent effects of domain-specific physical activity on mortality. We sought to investigate the association of physical activity performed in different domains of daily living on all-cause, cardiovascular (CVD) and cancer mortality. Using a prospective cohort design, 4,672 men and women, aged 25-74 years, who participated in the baseline examination of the MONICA/KORA Augsburg Survey 1989/1990 were classified according to their activity level (no, light, moderate, vigorous). Domains of self-reported physical activity (work, transportation, household, leisure time) and total activity were assessed by the validated MOSPA (MONICA Optional Study on Physical Activity) questionnaire. After a median follow-up of 17.8 years, a total of 995 deaths occurred, with 452 from CVD and 326 from cancer. For all-cause mortality, hazard ratios and 95% confidence interval (HR, 95% CI) of the highly active versus the inactive reference group were 0.69 (0.48-1.00) for work, 0.48 (0.36-0.65) for leisure time, and 0.73 (0.59-0.90) for total activity after multivariable adjustments. Reduced risks of CVD mortality were observed for high levels of work (0.54, 0.31-0.93), household (0.80, 0.54-1.19), leisure time (0.50, 0.31-0.79) and total activity (0.75, 0.55-1.03). Leisure time (0.36, 0.23-0.59) and total activity (0.62, 0.43-0.88) were associated with reduced risks of cancer mortality. Light household activity was related to lower all-cause (0.82, 0.71-0.95) and CVD (0.72, 0.58-0.89) mortality. No clear effects were found for transportation activities. Our findings suggest that work, household, leisure time and total physical activity, but not transportation activity, may protect from premature mortality

“…33 The reductions in BP found in the present study are clinically relevant, as a significant reduction in SBP of 3 mm Hg for normotensives has been shown to reduce cardiac morbidity by greater than 5%, stroke by 8-14% and all-cause mortality by 4%. 34 Thus, our data demonstrate that moderateintensity RE can be used in lieu of AE in a prehypertensive population to lower BP, and this is accomplished without weight loss.…”

Effect of 4 weeks of aerobic or resistance exercise training on arterial stiffness, blood flow and blood pressure in pre- and stage-1 hypertensives

et al. 2008

The benefits of aerobic exercise (AE) training on blood pressure (BP) and arterial stiffness are well established, but the effects of resistance training are less well delineated. The purpose of this study was to determine the impact of resistance vs aerobic training on haemodynamics and arterial stiffness. Thirty pre-or stage-1 essential hypertensives (20 men and 10 women), not on any medications, were recruited (age: 48.2 ± 1.3 years) and randomly assigned to 4 weeks of either resistance (RE) or AE training. Before and after training, BP, arterial stiffness (pulse wave velocity (PWV)) and vasodilatory capacity (VC) were measured. Resting systolic BP (SBP) decreased following both training modes (SBP: RE, pre 136±2.9 vs post 132±3.4; AE, pre 141±3.8 vs post 136 ± 3.4 mm Hg, P ¼ 0.005; diastolic BP: RE, pre 78 ± 1.3 vs post 74 ± 1.6; AE, pre 80 ± 1.6 vs post 77 ± 1.7 mm Hg, P ¼ 0.001). Central PWV increased (P ¼ 0.0001) following RE (11 ± 0.9-12.7 ± 0.9 m s À1 ) but decreased after AE (12.1 ± 0.8-11.1 ± 0.8 m s À1 ). Peripheral PWV also increased (P ¼ 0.013) following RE (RE, pre 11.5±0.8 vs post 12.5 ± 0.7 m s À1 ) and decreased after AE (AE, pre 12.6 ± 0.8 vs post 11.6 ± 0.7 m s À1 ). The VC area under the curve (VC AUC ) increased more with RE than that with AE (RE, pre 76±8.0 vs post 131.1±11.6; AE, pre 82.7±8.0 vs post 110.1 ± 11.6 ml per min per s per 100 ml, P ¼ 0.001). Further, peak VC (VC peak ) increased more following resistance training compared to aerobic training (RE, pre 17±1.9 vs post 25.8±2.1; AE, pre 19.2±8.4 vs post 22.9 ± 8.4 ml per min per s per 100 ml, P ¼ 0.005). Although both RE and AE training decreased BP, the change in pressure may be due to different mechanisms.

“…7 Physical exercise beyond 60% of maximal O 2 consumption does not lead to further reductions of blood pressure and might even increase blood pressure in hypertensives. 8,9 The intensity of exercise is generally monitored by heart rate. Adequate training heart rate can be assessed by determination of the anaerobic threshold using ventilatory parameters or lactate.…”

Beta-blockers do not impair the cardiovascular benefits of endurance training in hypertensives

et al. 2007

Aerobic physical exercise is broadly recommended as a helpful adjunct to obtain blood pressure control in hypertension. Beta-blockade interacts with heart rate, sympathetic tone, maximal workload and local lactate production. In the present randomized-controlled study, we compared the cardiovascular effects of an endurance training programme in elderly hypertensives with or without beta-blockers and developed a first approach to determine a lactate-based training heart rate in presence of beta-blockade. Fifty-two patients (23 with beta-blocker, 29 without beta-blocker) X60 years with systolic 24-h ambulatory blood pressure (ABP) X140 mm Hg and/or antihypertensive treatment were randomly assigned to sedentary activity or a heart-rate controlled 12-week treadmill exercise programme (lactate 2.0 mmol/l). In the exercise group, the training significantly decreased systolic and diastolic 24-h ABP, blood pressure on exertion (100 W) and increased endothelium-dependent vasodilation (flow-mediated vasodilation, FMD) and physical performance both in the presence and absence of beta-blockade (Po0.05 each). The extent of ABP reduction did not significantly differ in the presence or absence of beta-blockade (D systolic ABP 10.6710.5 vs 10.678.8 mm Hg, D diastolic ABP 5.778.6 vs 5.874.0 mm Hg). Mean training heart rate was significantly lower in the patients on beta-blockers (97.277.7 vs 118.377.5/min, Po0.001). Lactate-based aerobic endurance training evokes comparable cardiovascular benefits in the presence and absence of beta-blockade including a marked improvement of endothelial function. In the present study, target training heart rate with beta-blockers is about 18% lower than without.
