Effect Of Long-Term Physical Exercise On Blood Pressure In African Americans, Taunjah P. Bell, Katharine A. Mcintyre, Rosamary Hadley

International Journal of Exercise Science

International Journal of Exercise Science 7(3) : 186-193, 2014. Long-term physical exercise has been shown to noticeably reduce blood pressure (BP) and remarkably attenuate symptoms of hypertension. It is believed that physical exercise induces these beneficial effects by increasing the blood supply to the brain, enhancing the release of growth factors from skeletal muscles into the bloodstream, facilitating neurogenesis, stimulating angiogenesis, and influencing endothelial cell proliferation and subsequent endothelial cell membrane permeability. Previous findings also revealed that physical exercise significantly elevates brain-derived neurotrophic factor (BDNF) concentrations which appear to increase dramatically in BP-sensing neurons during hypertension. Elevating BDNF levels is …
