Increased heart size and resting stroke volume lower resting heart rate. Risk of heart disease and heart attack significantlylreduced. Increased levels of neurotransmitters: constant or slightly increased blood flow to the brain. Increased heart rate and stroke volume (amount of blood pumped per beat). improved ability to extract oxygen from air during exercise. Reduced risk of colds and upper respiratory tract infections. Increased pulmonary ventilation (amount of air breathed into the body per minute).
