Add Horsepower to Your Cardio: Increase Cardiac Output

QUESTION: True or false:  to improve your cardiovascular conditioning,  get your heart rate as high as possible in aerobic exercise?


ANSWER: False.  You improve your cardio condition by increasing cardiac output at lower heart rates.   Here's the mathematical equation used by doctors and exercise physiologists:

Q = HR x SV

Your cardiac output, Q,  is the product of your heart rate times your stroke volume - that's the amount of blood exiting the heart from the left ventricle every time it beats.   A strong heart pumps more blood with every beat.
