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.
