AST Sports Science BCAA 4500 - BCAA 4500 is the premium quality Branched Chain Amino Acid supplement designed for rapid muscle recovery and growth. Composed of the three highly anabolic amino acids Leucine, Isoleucine, and Valine, BCAA 4500 delivers the most powerful combination of natural anabolic substrates.
BCAA is short for Branched Chain Amino Acid. The BCAAs are leucine,
isoleucine and valine. These are 3 of the 9 essential amino acids in the
human body. Essential amino acids cannot be produced by the body. You
must get them through your diet. These 3 unique amino acids make up over
40% of your daily required essential amino acid intake.
BCAAs are unique in many ways but one extraordinary aspect of these 3
amino acids is that they bypass liver metabolism and are transported and
metabolized directly in muscle. They are the primary building blocks of
muscle tissue proteins. They also are carbon and nitrogen precursors for
the synthesis of alanine, glutamate, and glutamine.
Anabolic Effects of BCAA
BCAAs are shown to have anabolic effects in human muscle. They are
required for muscle tissue maintenance and preserve glycogen stores in
muscle tissue. The BCAAs are the primary amino acids responsible for
protein synthesis. In fact, the tissue building effects from protein are
primarily due to BCAAs.
The anabolic activity of BCAAs are from multiple pathways. Studies show
that the BCAAs and in particular leucine stimulates muscle protein
synthesis by acting as both a signal and a substrate. One way BCAAs do
this is through signaling mTOR activity in human muscle tissue. mTOR is
the primary regulator of muscle growth through amino acid sensoring.
BCAAs appear to signal mTOR to activate protein synthesis after
exercise.
This is a significant anabolic signaling effect activated by BCAA
Anti-Catabolic Effects of BCAA
BCAAs effect on increasing lean muscle tissue stems from its anabolic
activity as well as its anti-catabolic activity. Studies show taking
BCAAs before training is effective at suppressing muscle tissue
breakdown after training.
These study results suggest that BCAAs have a protein-sparing effect
during the recovery after exercise, and that protein synthesis is
stimulated and/or protein degradation is decreased. There are also
indications, though difficult to measure, that these same effects happen
during exercise as well.
With BCAA supplementation you get greater protein synthesis and less
protein breakdown.
Reduce Muscle Damage and Soreness
BCAAs reduce training induced muscle damage and soreness. Studies
performed on athletes supplementing with BCAA showed reduced levels of
key markers indicative of muscle damage, reduced inflammation, and
effectively reduced perceived muscle soreness.
Blood samples after BCAA intake showed dramatic decreases in creatine
kinase (CK) and lactate dehydrogenase (LDH) – both markers of muscle
damage. Lower levels of CK and LDH indicate less muscle tissue damage
and inflammation. Less muscle damage, soreness and inflammation leads to
quicker recovery times. Your body spends more time in anabolic mode.
BCAAs Reduces Fatigue and Enhance Endurance
One unique effect of BCAA is its prevention of central fatigue allowing
for high intensity training for longer periods of time. Research on BCAA
supplementation during exercise does show they increase mental alertness
and reduce mental fatigue.
In the blood stream BCAAs compete with tryptophan (the tranquilizing
amino acid). Tryptophan is the direct precursor to the neuro-
transmitter serotonin. This depresses the central nervous system and
produces symptoms of fatigue. When you exercise intensely, the ratio of
tryptophan to BCAA is altered in favor of increases in tryptophan. This
in itself makes you fatigued. Several studies with various types of
athletes confirm that BCAAs reduce mental fatigue and increase mental
alertness during their respective events.
Less fatigue during exercise and other physical activities as well as
sharper mental focus and concentration supports enhanced athletic
performance. Anytime you can train harder and concentrate better you’ll
get results faster.
Fast Ball Stays Fast
An interesting sport specific study (baseball) showed BCAA
supplementation prevented the drop in pitching velocity that occurs
after approximately 100 pitches – delaying fatigue and extending
muscular endurance. In this rather unique study, college and pro level
pitchers supplementing with BCAA showed no abrupt drop in pitching speed
when those that didn’t supplement saw significant speed decreases. BCAAs
could spell the end to the “Closer” in Major League Baseball.
While studies show significant decreases in training fatigue other
studies also show BCAA supplementation enhances endurance by extending
time to exhaustion during exercise.
Get Anabolic - Stay Anabolic!
As you can see, BCAAs are the most extensively researched amino acids.
When it comes to turning on anabolic activity in muscle tissue while
turning off anti-catabolic activity, no other amino acids have show
shown such direct effect.
To sum up what BCAA 4500 can do for you – increase anabolic effects of
exercise, decrease anti-catabolic effects of exercise, reduced muscle
damage, reduce muscle soreness during and after exercise, decrease
recovery time, increase mental focus, decrease mental and physical
fatigue, increase endurance, and enhance protein synthesis.
BCAA 4500 comes in a big 500 capsule bottle. Each serving contains 2250
mg of L-Leucine, 1125 mg of L-Isoleucine, and 1125 mg of L-Valine.
Capsules are easy to swallow and fast acting.
BCAA 4500 is your ticket to getting anabolic and staying anabolic!* |
