Gone is the belief that growing older means inevitable
and irreversible physical decline. Thanks to aging research, conducted in the
Institute for Aging Research at Hebrew Senior Life, we now know that not only
is physical activity possible at any age, but it is beneficial from staying
heart healthy, to helping prevent falls, to slowing down the onslaught of
dementia. With winter approaching, the tendency to hunker down in doors becomes
very tempting. Don’t let this happen. Winter is no excuse to assume a sedentary
lifestyle. However, safety is certainly a concern, and understanding physical
changes that come with age is important.
How does heart rate change with age and what should
seniors know in order to maintain a safe exercise routine? The good news is
that a person’s resting heart rate does not change significantly with age.
However, age does take a toll on how a person’s heart rate responds when
challenged by physical exertion. Research shows that as we grow older the
ability of one’s heart increases its rate during exercise to diminish.
The good news is, like with other muscles, we can build
the heart muscle with training. A more powerful heart can pump more blood with each
stroke, which helps older adults compensate for a slower response rate. So now
that you are convinced to stay active even as the days grow colder and shorter,
also take steps to stay safe. It’s a good idea to learn what a safe heart rate
is for you.
Although a moderate walking regiment may not need a
doctor’s blessing, you should always consult your primary care physician before
beginning anything more ambitious. But the research is conclusive that we can
build strength at any age. And we can all agree that a “bigger heart” is
something we all would want to cultivate in more ways than one!
