WHY ZERO CARBING IS A BAD IDEA
In order to
explain to you why you need carbohydrates I first have to talk about Muscle
Protein Synthesis.
What is Muscle Protein Synthesis?
The synthesis
of protein within the muscle is the method by which muscles are constructed and
repaired.
Proteins are
the compounds comprised of amino acids and amino acids are the building blocks within the body used for tissue formation.
Catabolism & Anabolism:
Muscle will
naturally break down, a process known as "catabolism." The breakdown
includes the physical separation of the fibers that comprise the muscle
structure. The subsequent repair of the damaged muscle is
"anabolism," the building up and the growth of the existing and
previously damaged fiber.
Protein
synthesis is the mechanism by which the body affects this repair and muscle
growth.
When your
goal is to grow and maintain your muscle it is very obvious that you would want
OPTIMAL Muscle Protein Synthesis to take place.
Why is Exercise important for Protein Synthesis?
The human
body synthesizes protein from diet at a rapid rate while the body is growing
through adolescence and into young adulthood. The rate at which protein is
synthesized slows significantly after age 20.
In an adult
the synthesis of muscle protein is also related to how the muscles are being
exercised.
Under normal
circumstances it is only the ongoing repair and maintenance of existing muscle
tissues that may be damaged through the course of daily living that takes
place.
The human
skeletal muscle will never get larger or stronger through either sedentary
activities or the consumption of particular foods or supplements alone!!
Muscular
activity is a prerequisite of meaningful muscle development through protein
synthesis.
All forms of
physical activity will direct specific stress into a muscle but activities that
involve explosive and powerfully focused movements (such as weight training)
the forces are directed against the muscle and the effect is much more
significant opposed to distance running, cycling or sustained intensity cardio
work where the stresses are cumulative and at a relatively lower level of
intensity.
Under stress
the muscle will naturally break down, a process known as
"catabolism." The breakdown includes the physical separation of the
fibers that comprise the muscle structure. The subsequent repair of the damaged
muscle is "anabolism," the building up and the growth of the existing
and previously damaged fiber.
Protein
synthesis is the mechanism by which the body affects this repair and muscle
growth and when the body produces more synthesized protein than it consumes
through its catabolic processes, muscle will be developed.
How to ensure Anabolism:
The essential
amino acid, leucine, is used as an indicator of the state your body is in.
A positive
leucine balance is evidence that this acid is present in the cells, a condition
consistent with protein anabolism. As I have told you earlier, amino acids are
the building blocks which proteins consist of and leucine is one of those amino
acids. Eating protein will then therefore provide you with leucine.
Where do carbs come in?
Researchers have
focused very much on the combined effects of protein AND carbohydrate
consumption after exercise during the last few years and they have found that a
combination of the two has a better effect on protein synthesis than just
protein alone.
It appears
that eating enough protein so that you consume 2-3g of leucine along with some
carbohydrates (20-30g) is an effective way to maximize muscle protein
synthesis.
Maintain constant balance:
It is very
important to remember that when proteins
are consumed along with carbohydrates immediately after exercise, the catabolic
process is not stopped within the affected muscles.
The process
of protein synthesis is immediately stimulated (given a kick-start).
This leads to
the prevention of further protein loss in the muscle.
As the
degradation of the muscle due to strenuous exercise will not reach its peak for
approximately three days after the exercise that affected the muscle, it is
important to continue the ingestion of protein.
The
consistent maintaining of balanced nutrition (Protein, Carbs & Fat) is
essential to the body's ability to respond on an ongoing basis to the demand
for muscle protein synthesis.
