BCAA - Power Packed Amino Acid Tablets BCAA's (branched chain amino acids)
L-leucine, L-isoleucine and L-valine are undoubtedly the single most
important group of amino acids for athletes. Around 33% of muscle protein
consists of BCAA’s. Even moderate exercise causes levels of BCAA’s to drop
rapidly which results in muscle tissue breakdown (catabolism), fatigue,
and a drop in testosteronelevels. Research shows that athletes who
supplemented with BCAA’s during tests experienced increased muscle growth
and strength, overall increases in energy, and improved muscle power
output.

Amino acids are essential to the human body. Bodybuilders can especially
benefit from supplementing amino acids because they aid in repair, growth,
and development of muscle tissue. The body, through assimilation of amino
acids, produces over 50,000 proteins and over 15,000 enzymes. Amino acids
are not only responsible for the production of all the body's enzymes
(including digestive enzymes), but they also play a key role in
normalizing moods, concentration, aggression, attention, sleep, and sex
drive. After protein is consumed, it is broken down into amino acids.
Then, individual amino acids are used to create necessary body proteins
and enzymes. Digestive enzymes break down the proteins a person consumes
into amino acids.

What Are Branched-Chain Amino Acids?
The BCAA Are A Group Of Three Essential Amino Acids:
1. Leucine
2. Isoleucine
3. Valine
The BCAA are different from the other 17 amino acids in that they are primarily
metabolized in skeletal muscle (Layman, 2003) and metabolized at a much lower
rate in the liver (Norton, 2005). The rate limiting enzyme in BCAA catabolism is
Branched Chain Keto Acid Dehydrogenase, which is much more active in skeletal
muscle than in the liver (Norton, 2005).
Point blank, exercise promotes increased BCAA oxidation (Shirmomura et al.,
2004). This increased degradation of BCAA helps maintain energy homeostasis by
providing carbon as a direct energy source and glucose homeostasis by providing
substrates for the citric-acid cycle and gluconeogenesis.
Amino acids are categorized as glucogenic, ketogenic, or a combination of
glucogenic and ketogenic. A glucogenic amino acid when metabolized gives rise to
pyruvate or other TCA cycle intermediates that can be used for the production of
glucose through gluconeogenesis.
A ketogenic amino acid is metabolized via the fatty acid pathway and gives rise
to actyl-CoA, a fatty acid precursor. Leucine is completely ketogenic, valine is
completely glucogenic, and isoleucine is both glucogenic and ketogenic. Valine
and isoleucine can both be used to produce intermediates for glucose production
via gluconeogenesis.
Due to leucine's metabolic properties (discussed below), increasing attention is
being given to it and its metabolism. Research has shown plasma leucine levels
to decrease during both aerobic and anaerobic exercise (Mero, 1999).
According to Freund and Hanani (2002), "Complete oxidation of leucine in the
muscle yields more adenosine triphosphate molecules on a molar basis than
complete oxidation of glucose." So leucine can provide skeletal muscle with more
ATP than an equal amount of glucose, which is due to leucine being completely
ketogenic and metabolized via the fatty acid pathway.
In order to meet the increased demand for BCAA during exercise the body breaks
down muscle tissue to supply additional BCAA. By supplying the body exogenous
BCAA during exercise, one can meet the increased demand for BCAA oxidation
without breaking down muscle tissue to supply the needed BCAA.
Because BCAA serve as a "fuel" for skeletal muscle, supplementing with
additional BCAA during your workout improves your performance without the added
calories or insulin spike (which can lead to fat storage) caused by
carbohydrates.
Leucine Stimulates Leptin Expression through mTOR activation in Adipocytes
Intake of leucine stimulates expression of the hormone leptin in adipocytes (the
primary site of leptin secretion) through activation of the mTOR pathway (Meijer
and Dubbelhuis, 2003). Leptin is a very complicated hormone; the gist of it is
involved in the regulation of metabolism, body weight, and appetite.
Leptin secretion is linked with body fat levels; higher body fat is associated
with higher leptin secretion and lower body fat is associated with lower leptin
levels. When you diet and lose fat, the amount of leptin you secrete decreases,
which makes your body "crave" food in an attempt to bring your body fat level
back up to where the body is comfortable (known as the body fat "set point").
Leucine has the ability to activate leptin expression and will cause the body to
think it is "fed" or receiving "adequate" calories, which will keep things
running (specifically your metabolism) smoothly.
BCAA and the Glucose-Alanine Cycle
The BCAA's are involved in maintaining glucose homeostasis through the glucose-alanine
cycle (see figure 1). The glucose-alanine cycle involves pyruvate (derived from
glucose/glycogen) being transaminated in muscle to form alanine, with the BCAA
serving as the main nitrogen source (donors) for the synthesis of alanine (Holecek,
2002).
The newly synthesized alanine is released in the blood stream and sent to the
liver where it is converted into glucose through gluconeogenesis. This glucose
can then be sent from the liver back to the working muscle to be used as fuel.
Supplementing with BCAA allowing your body to create glucose to use for fuel
without the added calories or insulin spike (which can lead to fat storage)
caused by carbohydrates.
L-Glutamine
Glutamine
is a glucogenic (glucose creating), nonessential amino acid that has multiple
roles in the body. Glutamine is synthesized mainly in skeletal muscle and the
liver and acts as a "nitrogen shuttle" between organs, a fuel for cells of the
immune system and intestines, and a precursor for nucleotide synthesis (Holecek,
2002).
Glutamine is also a powerful cell volumizer (Haussinger et al. 1993). An
increase in cell volume, also called cell swelling, stimulates anabolic pathways
(synthesis of proteins and glycogen) and inhibits catabolic pathways (protein
degradation) (Haussinger, 1993).
According to Houston (2001), "Glutamine content in skeletal muscle and other
tissues appears to have a regulatory role in whole body protein synthesis."
Glutamine levels inside muscle govern protein synthesis and nitrogen balance and
therefore muscle growth (VanAcker et al. 1999).
Adequate glutamine concentrations are needed for optimal health and skeletal
muscle hypertrophy. Therefore one would want to keep glutamine levels elevated,
especially during/post exercise.
Glutamine Metabolism and Exercise
During times of stress, such as exercise, skeletal muscle glutamine levels are
depleted. This glutamine released from skeletal muscle is derived from muscle
proteins, the intramuscular free amino
acid pool, and newly synthesized glutamine (VanAcker, 1999). The newly
synthesized glutamine is created by using BCAAs obtained from muscle protein
breakdown (Holecek, 2002).
Plasma and muscle glutamine levels are decreased post workout and it can take
hours before they are restored (Rowbottom, 1996). A study examining the effect
of free-form glutamine and glutamine peptide ingestion on muscle glycogen
resynthesis found that plasma glutamine was decreased by 20% post workout with
the ingestion of glucose only (control), showed no change with ingestion of whey
protein or wheat protein hydrolysate plus glucose drinks, and a 200% increase
with ingestion of free-form glutamine plus glucose drink (VanHall, 2000).
Free-form glutamine supplementation was needed to elevate plasma glutamine
levels post workout.
In addition to restoring and elevating plasma glutamine levels, oral glutamine
supplementation increases muscle glycogen storage to the same capacity as
glucose (Bowtell, 1999). Glutamine can replenish glycogen levels without the
added calories or insulin spike (which can lead to fat storage) caused by
carbohydrates.
Mammalian Target of Rapamycin (mTOR)
The Mammalian Target of Rapamycin (mTOR) is one of the body's protein synthesis
regulators. mTOR functions as an energy sensor; it is activated when ATP levels
are high and blocked when ATP levels are decreased (AMPK is activated when ATP
decreases, which works antagonistically to mTOR).
The main energy-consuming process in the cell is protein synthesis. When mTOR is
activated (high ATP levels sensed) protein synthesis is increased and when mTOR
is suppressed (low ATP levels are sensed) protein synthesis is blunted.
MTOR activation is vital for skeletal muscle hypertrophy. Interestingly, mTOR is
also a nutrient sensor of amino acid availability, specifically of leucine
availability. Research has shown that regulation of mTOR by ATP and amino acids
act independently through separate mechanisms (Dennis et al., 2001).
