Keeping Fit
as You Age
It's a
commonplace observation that as you age you have to work harder
to keep the pounds off and to stay fit. One major reason is the
inescapable biological fact that metabolism slows as we age;
inescapable for now at least, until medical technology finds
some safe way to alter it.
Genetic
research into aging is trying, in a way, to do just that.
Several studies in the last two decades have pointed to hints
about precisely what causes aging. If they get sufficient
knowledge of the subject, there is some hope of altering the
situation.
Until then,
there are several things a sensible person can do to stay trim,
flexible and within a healthy weight or body fat percentage
range. At any age, diet and exercise are the twin partners
required to achieve those goals.
For some,
working out an hour per day every day - a five mile run, a long
swim, hitting every station on the weight machine - is still
feasible. Others will have to adjust their routine to what is
realistic for their own circumstances. Don't ignore the signals
that will help guide you to do that. Mild discomfort is to be
expected, especially the day after a vigorous workout. Extreme
pain is a sign something is wrong.
There are
dietary changes that will be needed, too.
As we age
there's a greater temptation to indulge in tasty, but high
sugar, high fat foods. We see it as a reward for all the years
of hard work and dietary discipline. Unfortunately, we pay a
higher price later in life for those than we did in our 20s or
40s.
An occasional
dessert is actually healthy, both for your state of mind and
the sugar and fat. Both are essential compounds in moderation,
though simple sugars are preferable to complex and unsaturated
fats are preferable to saturated. Sugar is essential to
generating the energy needed for all biological processes.
'Good' fats help regulate hormones, neural processes and other
vital activities.
Staying active
is equally as important as the proper diet. A good walk helps
keep the cardiovascular system in working order. Mild stress on
the muscles and joints keeps them lubricated and firm. Both
muscle mass and bone density reduce dramatically in sedentary
individuals.
Studies show
that a sedentary 65 year old will have (on average) only 60% of
the aerobic capacity of a 30 year old. Those who do no strength
training lose muscle mass equivalent to seven pounds per
decade. But those statistics are not written in stone. Exercise
can help improve them tremendously.
Studies at
various universities carried out for 25 years show that runners
who continued to train kept almost all their capacity of 20
years previous. Those who engaged in resistance training
maintained muscle mass equal to that of ten years earlier. Use
it or lose it.
A person who
has been idle, but suffers no debilitating disease, can reverse
their odds. Start slow and think long term. Pain from overdoing
it is one of the leading causes influencing people not to stick
with it. Take long walks, then work up to more vigorous
activities under the guidance of a
professional.
Live a long and
healthy life, not just a long one.
