Perhaps the most significant nugget of information that I attained in my post cardiac bypass rehabilitation was the"Borg" scale. The
Borg Rating of Perceived Exertion (RPE) is a way of measuring physical
activity intensity level. Perceived exertion is how hard you feel like
your body is working. It is based on the physical sensations a person
experiences during physical activity, including increased heart rate,
increased respiration or breathing rate, increased sweating, and muscle
fatigue. Although this is a subjective measure, a person's exertion
rating may provide a fairly good estimate of the actual heart rate
during physical activity.
In
contemplating a structured syllabus that promotes good cardiac health,
consideration may be given to the inclusion of the Borg scale.
Most
of our syllabi contain at least some cardiac work. However a graduated
increase in the hearts work-rate is required. Overworking the heart is
obviously not desirable though this can easily occur through over
zealous instruction.
Therefore some knowledge of how to use the Borg scale may prove a useful tool.
