Exposing The Training Effect
Your heart is essentially a big bag of muscle –
and a very powerful one oat that. It has to be to push blood
continuously around your body. The power of the heart is
most noticeable when you undergo any form of aerobic exercise.
Passing from rest to peak of your exercise workout the amount
of blood pumped per minute (known as the stroke volume)
by your heart can increase up to six fold.
This change forms part of what is known as "training
effect". In fact the term covers any physiological
change occurring during vigorous exercise but is most aptly
demonstrated by the heart. During activity heart rate (beats
per minute) is directly proportional to the work involved.
So as the level of activity increases so does heart rate.
Typical examples: at rest heart rate might be 72 beats per
minute; during a brisk walk it might rise to 110; and whilst
running reach 150 beats per minute.
As you become fitter you will notice a lesser rise in heart
rate from the resting level as activity increases. In other
words your heart begins to pump much more efficiently. This
is the "training effect"
