| Why
are Amino Acids Important to the Body? |
Yes, Amino acids are beneficial to strength athletes. But they are also important
additions to a dietary supplement program for other reasons as well. Amino
acids are considered the building blocks that comprise protein. Protein, it
follows, cannot exist without the correct combination of amino acids. If any
essential amino acid is low or missing, the effectiveness of all others will
be proportionately reduced. In the body, adequate protein intake is vital for
virtually everything from healthy muscles, ligaments, tendons, organs, glands,
nails, hair and most body fluids. Besides water, protein comprises the largest
portion of our body weight, and as such, the body's requirement for protein
is directly related to good health. Additionally, the central nervous system
cannot function properly without amino acids, which are necessary for the brain
to both send and receive information. In fact, not only does every cell in
the body contain protein, but protein makes up half of the body's dry weight.
Protein is found in muscle, bone, cartilage and blood, as well as enzymes and
hormones. Protein essentially allows muscles to contract and hold water, gives
hair and skin a protective coating, and provides the rigid framework of bones
and teeth. Protein also helps tissue form, regulates the body's water and acid-base
balance, and stimulates the production of antibodies.
Amino
acids supplements are popular among bodybuilders, athletes and fitness conscious
people. Their popularity stems from the belief that they promote an anabolic
state causing muscle growth, increased recuperative abilities and higher
strength levels. Amino acids are the foundation of protein, the stuff the
body must have for growth, repair and muscle-building. Before amino acid
supplements were accepted for Athletes, protein powders dominated the market.
Your muscles are hungry for protein and is needed for repairing. Without
total repair the body cannot start to build muscles. The basic components
of protein are amino acids. Since proteins are broken down into amino acids
by the digestion system, logic suggested that digestion could be by passed
by taking amino acids supplement directly.
Intake
of Amino Acids
All athletes need more protein
when exercising heavily. It's been estimated that athletes require anywhere
from 1 to 2.0 grams of protein per kilogram of body weight a day. Since amino
acids are the building blocks of protein, they are necessary for building and
re-pairing muscle as well. Collectively, they work to raise the body's nitrogen
level, helping to facilitate muscle repair and accelerate post work-out recovery.

Types of Amino Acids
A reputable amino acid supplement in conjunction
with a nutritionally complete diet can help to
form all of the muscle one can build in a day without
the problems of excess fat and or cholesterol but
more important, without straining the digestion
system. it would be easy to become confused with
different supplement companies offering different
types of amino acid supplementation. Amino acids
are available in a variety of forms, single to
multiple amino combinations, free form, peptide
bonded and branched chain. I would like to describe
the difference between all three types of amino
acids (free form, peptide bonded, and branched
chain) and how each one can benefit your needs.
Free
Form and Peptide Bonded
Free form amino acids are not bound to any other amino acid. Peptide bonded
amino and carboxyl groups combine to form "peptide" bonded. A peptide
bonded amino acid, then consists of two or more types of amino acids linked
by peptide bonds. Studies have shown that peptide bonded amino acids are better
absorbed by the small intestines than are crystalline free form amino acids.
Crystalline free form, unlike peptide bonded, are single amino
acids molecules. Free form refers to the fact that they are free of other amino
acids. In recent adverts some companies have advertised that free form amino
acids are the purest and most biologically active source of amino acids, in
some circumstances this may be true.
I believe peptide bonded are the best for every day use. The body has to first
break the peptide bonded molecules down into single molecules before they can
be absorbed into the bloodstream, this process takes around 1.5 hours, where
as free form are already at this stage, and may be absorbed too quickly in
the stomach, never making it to the bloodstream or the muscles. The basic rule
that I always tell athletes to follow is to use peptide bond amino acids for
improving the amino acid content of many everyday proteins like fish and many
meats. Peptide bonded Aminos are usually less expensive than those in the free
form.
Branched
Chain Amino Acids
Branched
chain amino acids are for recovery, because of their
superior biological activity. Branched chain amino
acids consist of three Aminos, L-Leucine, L- Isoleucine
and L-Valine. As natural anabolic muscle-building supplements,
they regulate how protein is used by the body and play
a role in protein metabolism in muscles. While all
of the other amino acids are broken down in the liver,
branched chain amino acids are oxidized in the muscle
tissue. Branched chain can be very beneficial for those
using steroids or those on high protein diet due in
the stress these can play on the liver. Almost like
a calorie for the muscle, Amino Acids limit the amount
of nitrogen released, preventing a rapid decrease in
muscle protein synthesis. During intense physical exercise
the stress placed upon muscle fibres causes damage,
Amino Acids in any form can both can reverse the damage
and build increased muscle tissue. The type of amino
acids depends on each individual needs. For those who
don't feel they are eating enough protein during meals
than try adding peptide bonded Aminos with each meal
to not only increase the biological value of those
but to also increase the amount of protein.
Branched
chain amino acids, or Peptide bonded, but with a high
concentration of Glutamine, before and after work-outs.
If you eat enough protein will each meal, you may feel
you may not need to add an amino acid supplement to
your meal, but check the amino acid content of your
protein rather than just the amount, you may be eating
a lot of protein but if it is of poor biological value
your muscles will not receive the blocks it needs to
build.
