Since oxygen is transported through the bloodstream, the heart needs to pump more blood to supply the working muscles with oxygen. The systolic blood pressure rises because of increased force of contraction of the heart. Exercise allows the heart to pump blood more efficiently into the circulation as a result of stronger and more efficient cardiac contractions, greater blood perfusion of tissues and organs, and higher oxygen delivery. Exercise also stimulates the growth of new blood vessels, causing blood pressure to d
