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 than
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.
