These exercise principles were first introduced to me about 100 years ago.
I was
on the high school track team coached
by Mr. Miller who had us do at
least 20 minutes of “wind sprints”
every day.
We would jog
around the track for a while,
suddenly break into a sprint for
about 40 yards and then slow
down to a walk as our lungs
cried out “Please don’t do that
again.”
In
the beginning we looked upon
this activity as an extreme form
of punishment but we learned
later that these alternating
intensity workouts, now known as
interval training, dramatically
improved our energy and
performance.
Don’t panic. I’m not recruiting
for the geriatric track team but
there is a law of nature at work
here that applies to the young
or old, fit or fat. Our Creator
designed the human body with the
miraculous ability to adapt.
Natalie, our adopted
granddaughter who is pictured on
the left, is a great
illustration of the human body's
ability to adapt. She spent the first
thirteen months of her life
confined to a crib in a crowded,
understaffed hospital in
Siberia.
Soon after getting settled in
her new home in Texas, Natalie
immediately began to make up for
lost time. In a matter of weeks
she rushed from crawling to
walking to sprinting like an
Olympic gymnast.
Natalie’s Mom
and Dad will attest to the fact
that her “normal” activity level
accelerated from inactive to an
astounding high-energy dynamo.
In case you're interested her
picture is shown above.
If you are a couch potato
(heaven forbid) or in the “as
little as possible” exercise
category you too can make
dramatic progress in your
physical condition by employing
the interval training concept.
And it will take as little as
three 29-minutes sessions per
week.
A Canadian study followed
exercisers who burned 300 to 400
calories per session. A control
group matched the same routine
one-third of the time.
Two
thirds of the time they
exercised for a shorter period
during which they burned only
225-250 calories—but they
included occasional 30-90 second
bursts of high-intensity
exercise.
The fat loss of the
group who worked out less was
nine times greater than the
subjects performing moderate
exercise.
Of the three key exercise
variables…how often you do it,
how hard you work and how long
you last, intensity has the most
powerful effect. Your body
responds to short bursts of
intensity by releasing a cascade
of fat-mobilizing hormones and
anti-aging growth hormones that
supercharge your metabolism and
burn extra calories for 24 hours
or longer.
Fat loss is only one of the
benefits. A new study by British
researchers tracked 1,975
healthy men over ten years.
The
men who exercised the hardest
had a 47% percent lower risk of
death from all causes and a
whopping 62% lower risk of death
from heart disease, compared
with those who reported very
little or no intense exercise.
The best part however is that
these benefits were achieved
with as little as nine minutes
per day of vigorous activity.
The principle of adaptation also
applies to strengthening your
muscles, which need to be worked
hard to become stronger.
The
average person loses up to 20
pounds of muscle by age 70 and
since each pound of muscle burns
up to 50 calories per day it is
easy to see why “love handles”
and “spare tires” sneak up on
us.
If you are on a low-carb eating
program such as Atkins or South
Beach your exercise has a
distinct advantage over the
low-fat dieters.
Low carbers
have a limited amount of
glycogen (stored sugar)
available and so the body
utilizes the fat on the belly,
hips and other unwanted places
as the primary sources of energy
during exercise.
Think you’re too old or out of
shape to get started on “wind
sprints”? It’s never too late to
start feelin’ great!
