Is a Slow Heart Rate Good for You? ------------------------------------------------------------------------------ QUESTION: Is the story that a slow heart rate is good for you really true? ------------------------------------------------------------------------------ ANSWER: If the rate of the heart is not a result of any medication, then we can offer you a full explanation. Resting heart rates can be as low as 30 beats per minute in a highly trained endurance athlete, and it is a good sign because it generally reflects a strong and highly efficient heart--a heart with a lower rate uses less energy than a heart with a faster rate if both pump the same amount of blood per minute. Slow heart beat--called bradycardia--is an advantage for athletes. During an endurance event, if you have a low resting heart rate, your heart may not have to reach as high a rate as that of someone who is less trained, and it will take longer to reach your maximum rate. A slow heart rate is also a plus for someone with a heart problem. Because a slow heart rate means you have a longer range before you reach your maximum, there is less chance that your heart's need for oxygen will exceed its supply--a condition that causes chest pain and even death of heart muscle. Heart rate slows after only a few weeks of endurance training, and in time, the heart becomes larger and stronger as the heart rate decreases further. Because of this, slow heart rate is used as a measure of aerobic fitness. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
