For the Calorically Disadvantaged Everywhere

We are all at risk. Much better worth our reading time than learning about
the latest nutrient!
If this doesn't make you want to get up and move your ass, perhaps its too
late anyway. :-)

The Deadliest Sin March-April 2004 From survival of the
fittest to staying fit just to survive: scientists probe
the benefits of exercise, and the dangers of sloth. by
Jonathan Shaw.

Excerpts: "We've spent years studying numerous nutritional
and lifestyle factors," says Frank Hu, associate professor
of nutrition and epidemiology at the Harvard School of
Public Health (SPH). "Good nutrition is essential for
health," but once-promising discoveries, including
antioxidant supplements like beta-carotene, have turned out
not to be magic pills. "The single thing that comes close to
a magic bullet, in terms of its strong and universal
benefits, is exercise."

"People who engage regularly in vigorous aerobic exercise
undergo some remarkable adaptations. Not only will they
develop more mitochondria, glucose transporters, and
oxidative enzymes in their muscles, they will grow new
capillaries in the skeletal muscles, the heart, and the
brain. The left ventricle of the heart will grow larger,
and pump even more effectively as total blood plasma volume
increases. The number of circulating red blood cells will
also rise, improving the ability to carry oxygen. Blood
pressure will go down, as will the heart rate at rest."
Muscles and liver will learn to store more fuel in the form
of glycogen, further improving endurance. Circulating
levels of cortisol, an anti-inflammatory hormone and mood
enhancer, will go up, as will epinephrine and
norepinephrine, hormones that regulate, among other things,
the burning of adipose tissue.
*****
Many of these positive adaptations involve common
physiological markers of aging, including blood pressure,
cardiac output, cholesterol levels, endurance, and strength,
says SPH and HMS associate professor I-Min Lee. "Almost
everything that declines physiologically as you grow older
improves with exercise."
