How to Supercharge your Energy Levels through
Exercise
Your energy levels will depend on several factors, including
genetics, nutrition, sleep habits, and emotional stress. Some of
these you have no control over But there is one VERY important
factor that you do have control over and that is your ability to
take part in physical exercise.
Need a source of vast power and energy?
Look no further than your gym.
The link between physical fitness and energy is so strong, that
doctors have lately been prescribing exercise as treatment for
chronic fatigue, depression, seasonal affective disorder (SAD), and
insomnia, for instance.
If sufferers of the most stubborn kind of fatigue can be
energized with exercise, imagine what can do for those of us who
experience ordinary, every-day fatigue.
Feel Great At Mid-Afternoon
Your brain thrives on oxygen. Blood transports oxygen to the
brain, so the greater blood flow to the brain, the greater the
oxygen supply the brain has. As you increase your heartbeat with a
vigorous workout, more blood surges through the brain, more oxygen
gets absorbed by your brain cells, and you feel more mentally alert
and energetic.
Experts point out another long-term cause-and-effect
relationship between exercise and blood flow to the brain: as you
continue exercising, the number of capillaries (small blood vessels
between your arteries and veins) throughout your body will grow.
More blood flow through your "pipes" means more oxygen will be
supplied where you need it.
Regular exercise also keeps the pipes clear and circulation
healthy by preventing atherosclerosis (buildup of plaque). Regular
exercise can actually REVERSE atherosclerosis when combined with a
healthy nutrition plan. When you have atherosclerosis in check,
your brain is virtually guaranteed for the rest of your life.
Blood also carries glucose, the simple sugar that's the primary
fuel source for your entire nervous system of which the brain is
the command center. Glucose's production starts the metabolism of
carbohydrates. Various enzymes, plus your body's ability to use
glucose to produce ATP, the more important energy chemical in the
body, control this production. When you exercise, you increase the
level of those enzymes and their activity.
In other words, when you exercise regularly, you boost your
enzymes, resulting in more glucose, and your body is more efficient
in using the glucose. You get a larger supply of ATP, which helps
fight off the mid-afternoon energy drop-off.
Increase Metabolism
It's no secret that strength trainers are firmer and stronger
than sedentary folks. How could it be otherwise?
Resistance exercise builds muscle, pure and simple. The more
muscle you have, the higher your metabolism, and the more calories
you burn even at rest.
So why does "strong and toned" equate to more energy?
For starters, heavy people have to lug around more weight all
day long. When the overweight climbs a flight of stairs, do yard
work, or even just carrying the garbage can to the curb, they're
also carrying that excess weight, making almost everything they do
more exhausting.
Better-conditioned muscles make every task that much easier,
regardless of body weight. When you exercise, your ability to use
muscle fibers is increased. So you require less effort to perform
any physical task.
A strong body also has a stronger immune system. Being sick
drains us of energy, and exercise, by boosting immunity, staves off
illness. Recent research has shed light on why the strong may get
sick less often and recuperate faster when they do get sick:
exercise increases the activity of natural killer cells in the
bloodstream.
Less Stress
A great deal of research supports that weight lifting is one of
the most effective means of battling depression and stress. One of
the main fatiguing factors of depression and stress is lack of
sleep. In a recent Stanford University study, formerly sedentary
insomniacs who began to exercise fell asleep 15 minutes faster and
were able to sleep an hour longer than they had before becoming
active.
Boost Brain Fitness
To this point, we've been talking about the benefit of exercise
on mental energy. But is it possible that being in shape might
translate to even greater mental benefits, such as increased
intelligence, creativity, memory, or reasoning ability? It's very
possible.
Studies show that both factors of mental stimulation and
exercise were contributing to the increase of the brain's learning
centers in different ways. Mental stimulation results in more
synapses (the little gaps between brain nerve cells that enable
them to communicate with one another), while exercise increases the
number of capillaries in the cerebellum and cerebral cortex (two
areas of the brain crucial to intelligence.)
Take a Walk
Medical research results could hardly be clearer: Taking a walk
is one of the best ways to take charge of your health. A study in
the Journal of the American Medical Association (February 11, 1998)
showed that walking briskly for half an hour just six times a month
cut the risk of premature death in men and women by 44 percent. A
study in the New England Journal of Medicine (January 8, 1997)
reported that men 61 to 81 years old sharply reduced their risk of
death from all causes, including cancer and heart disease, by
walking two miles a day. Other research has shown similar results
for women.
Recent studies have concluded that moderate amounts of exercise
- including walking, jogging or using a treadmill for one hour,
four to five times a week - can turn back the aging clock 30 years
for middle aged men.
Consistency is probably the most important part of your workout.
The more committed you are to walking all or most days of the week,
the healthier you'll be. Remember that short walks are better then
none at all. Health, like life, is a journey. All you have to do is
take the first step.
