This can be achieved by a diet, such as the DASH diet, that is high in potassium 5. A BP-lowering effect of increased physical activity has been repeatedly demonstrated in clinical trials, espe- cially during dynamic aerobic exercise,S6.2-18,S6.2-20,S6.2-22 but also during dynamic resistance trainingS6.2-18,S6.2-21 and static isometric exercise.S6.2-18,S6.2-19,S6.2-31 The average reductions in SBP with aerobic exercise are approxi- mately 2 to 4 mm Hg and 5 to 8 mm Hg in adult patients with normotension and hypertension, respectively.S6.2-18 Most trials have been of relatively short duration, but increased physical activity has been an intrinsic compo- nent of longer-term weight reduction interventions used to reduce BP and prevent hypertension.S6.2-3,S6.2-4,S6.2-12 BP-lowering effects have been reported with lower- and higher-intensity exercise and with continuous and in- terval exercise training.S6.2-18,S6.2-103 Meta-analyses sug- gest isometric exercise results in substantial lowering of 6.
