Novel exercise-based strategies for lowering blood pressure

Cardiovascular diseases remain the leading cause of death worldwide. Above-normal blood pressure is the primary modifiable risk factor for cardiovascular diseases and rates of blood pressure control remain suboptimal. Aerobic and resistance exercise are recommended lifestyle interventions for lowering blood pressure; however, adherence to exercise guidelines is low, contributing to poor rates of blood pressure control. Thus, alternative forms of physical activity that lower blood pressure and promote adherence are needed. This review covers isometric exercise, the Weekend Warrior physical activity pattern, and heat therapy as blood pressure lowering strategies. Randomized controlled trials support isometric exercise for lowering blood pressure; however, the mechanisms of action require further investigation. The Weekend Warrior physical activity pattern, i.e., concentrating physical activity in 1-2 days/week, is associated with lower rates of hypertension in cohort studies, but clinical trials are lacking. Cohort studies also support that regular sauna use is associated with lower rates of cardiovascular diseases. Small clinical trials also suggest that heat therapy can lower blood pressure; however, study designs are heterogeneous and the results are mixed. Overall, isometric exercise, the Weekend Warrior physical activity pattern, and heat therapy all represent potential lifestyle approaches for lowering blood pressure and reducing cardiovascular disease risk.
