I introduced my 76
year old friend, Jeanne, to weightlifting in early January. Jeanne
has been an avid swimmer all her life, until last summer when
a leg injury sidelined her for ten weeks. In November, she suffered
a racing heartbeat that accelerated to 200 beats per minute. The
cause of this incident was never found, but after a few weeks
of rest, Jeanne agreed to start on a weight lifting program with
me.
Weight lifting, more
formally known as weight resistance training, improves a component
of fitness that is different from the component improved by cardio
vascular exercise. Cardiovascular exercises consisting of walking
and swimming keep the heart and lungs strong but do not increase
muscle mass. Weight lifting improves strength, increases muscle
mass, and in some instances. improves certain health conditions
by stimulating some metabolic processes.
Geriatric fitness
researchers are aware that inactivity takes a far heavier toll
on older men and women than on any other age group. One weightlifting
study among nursing home residents found that the participants
whose average age was 90 increased strength almost three-fold
during the eight weeks residents participated regularly in systematic
weight lifting routines.After only three weeks of inactivity,
however, they lost almost half of their regained strength.
As soon as Jeanne was
able to, she resumed her walking schedule. I could look out my
window on sunny afternoons and see her trekking along the grassy
lawns of our single-story apartment buildings, accumulating mileage
on the endless ribbons of rolling sidewalk. Usually, when I rush
outdoors to exercise, I wear ragged sweats and pull my hair back
with a rubber band. Jeanne never leaves her house unless her short,
fluffy white hair is carefully curled and brushed. Even at the
gym, her cotton slacks are neatly pressed, and she wears jerseys
rather than t-shirts. She pays careful attention to details, and
her participation in regular walks has paid off. When we started
the weight lifting program, she was more able than many women
her age to take on a full body routine. Her coordination and dexterity
are good.
A basic test of strength
is the chest press. A person pushes a weight, usually a weighted
bar, away from their own chest. Normally, this exercise is done
flat on a bench. The person presses weights from the chest straight
up, brings them down again and repeats the action ten times to
make one set.
On our first day together,
Jeanne could not chest press two five-pound dumb bells, one in
each hand. I took her to the chest press machine, which allows
the person to sit upright and push two handles at chest level
forward, and then bring them back to the chest, and then repeat
the action ten times for a set. On the machine, Jeanne was only
able to do 15 lbs. On a weight machine, a person can do a heavier
set of weights than can be done freely on a bench. Weight machines
use cables and offer a certain amount of support through the lift,
so they are easier for beginners.
Lifting "freely," without
a machine or cables, forces the person to use additional muscles
to balance the weights and regulate how quickly or how slowly
they perform the action of the lift. Machine weight lifting is
best for beginners in order to learn proper motion and lift safely,
but free weight lifting is still the best form of weight lifting
for building strength efficiently.
After our first weight
session, Jeanne viewed weight lifting as a necessary chore. She
thanked me for the time I had devoted to her instruction. A week
later, in our third session, she was moving through the exercises
with more assurance and focus. The next week, she experienced
a burst of that euphoria that weight lifters understand. After
we finished, I asked her how she felt.
"I feel good!" she
exclaimed. She beamed at me through her thick, round glasses.
"I feel lots stronger and ready to get some work done!"
For Jeanne, this means
cleaning her house. She put her arm around me as we walked from
the gym to our cars. Her voice was happy and confident. "Thank
you for all the time you're putting into this!"
"You're welcome," I
told her. "We have to keep you independent so you can go on being
my neighbor. You know, so I can get all that free advice so conveniently."
I smiled at her.
She met the comment
with a burst of laughter, hugged me, and said goodbye until next
time.
Consistent weight training
does tend to enhance moods. A sense of well being is one of the
common benefits of methodically and routinely exercising all the
muscles of the body.
I was glad that Jeanne's
spirits were so good, because in our next session, I started to
focus on specific muscles within the major muscle groups. The
muscles of the leg group are made up of the gluteals ("glutes),
which are the muscles of the back side. These muscles guide us
as we sit and stand, or as we crouch. They also provide some lift
for these actions. The hamstrings run down the back of the upper
leg and assist in a variety of tasks. They actually help us lift
things correctly if we have to pick something up from the floor.
They provide the spring for every jump that we make, and they
also help retract us down into a crouch or erect the upper body
up from a crouch. On the front of the upper leg, the quadriceps
also assist in any motion that involves springing forward, but
they are most useful in lifting the lower leg in a kicking motion
or raising the knee. The calf muscles are in the back of the lower
leg, running from the back of the knee to the heel. They help
a person stand up on her toes and assist in jumps, especially
the short skips.
All the muscles of
the leg work together to perform other vital actions, especially
for senior women. They stabilize the leg throughout the stepping
motion and assist in maintaining balance. More than anything else,
I was concerned about the danger of Jeanne falling.
For her, a fall could
destroy her independence. A fall can break bones or cause other
injuries. Having to go into any type of convalescent care would
drain savings and remove her from the productive, happy life that
she now leads. Developing leg strength is crucial for the more
mature woman who wants to stay independent.
When we worked together
recently, I tested Jeanne's hamstring muscles with an exercise
called an isolated leg curl. To do a leg curl, a person must keep
the knee stable and lift the heel until it touches the back side.
I had already noticed that Jeanne's leg curling was weak. When
I put her on a special machine that isolates the hamstring of
each leg, I found that she could not move a two and a half pound
weight more than a few inches.
This means that with
Jeanne's sitting and standing up, walking and stair climbing,
she is compensating for this weakness with other muscles: holding
onto something to assist her to rise, leaning forward to let the
quadriceps take the stress and pushing off from a hard chair with
her hands. Weak hamstrings mean that if a person has to walk on
steep, slippery, or unstable ground, the muscles may not have
enough strength to stabilize the stepping action and the person
could suffer a fall.
Since everyone's muscles
begin to lose mass after the age of about 28, the problem can
only get worse unless a person begins to increase muscle mass
through direct effort. We went to the very basics of the leg curl.
I went to Jeanne's house and showed her how to stand against the
cold kitchen stove, brace the right knee against the front of
the stove and lift the right heel up as close to her backside
as she could. I instructed her to do this twenty times each leg
to make one set, and to do three sets a day. Jeanne faithfully
followed these directions, and when we next met at the gym, she
was able to move the two and a half pound weight further on each
isolated leg curl. We also attended to 'step-ups' more ardently,
stepping up and down on a stable platform, working the muscles
that make for a stable stepping action.
In performing her exercises,
Jeanne is showing vast improvement. She can now chest press two
five-pound dumb bells, and she can chest press 30 pounds on the
machine. There are three basic exercises for the upper body (chest
press, shoulder press, wide-bar pull down), and Jeanne has almost
doubled the weight she can lift during these exercises. This is
a terrific improvement.
Another benefit has
been Jeanne's presence in the gym. I enjoy seeing the beefy, tatooed,
shaven-headed guys greeting her. I've always noticed that truly
dedicated athletes, no matter what look they adopt for themselves,
respect other people who are willing to consistently work at improving
their health, fitness, and skills by regular exercise. The regularly
attending women and men at the gym are quickly making room for
seniors. Since Jeanne started, I've noticed three newcomers in
this age group. One of the professional trainers updates me on
Jeanne's progress and another has offered to unearth a textbook
from college that includes a chapter on weight lifting for those
over 65.
The time is right for
older men and women to claim a place for themselves in consistent
physical training. Of course a physician's approval is essential
before beginning a training program. A good course of instruction
is also necessary. While other people might raise their eyebrows
at the sight of these older athletes hefting barbells people who
love physical fitness are always willing to make room and offer
encouragement---especially to the oldest of newcomers.
