An effective blend of USP grade Leucine, Isoleucine and Valine that are
crucial for muscle coordination and development.
One of the challenges in maintaining focus during intense training and physical
exercise is mental fatigue. Whereas most athletes worry about and take
corrective action to ward against muscle fatigue, mental fatigue must be
combated as well. In fact, recent research has placed increasing emphasis on
mental fatigue during exercise. This mental fatigue is commonly referred to as
central fatigue because of the involvement of the central nervous system. While
central fatigue does not affect muscles, it can reduce the capacity to perform
optimally.
There is a correlation between the amino acid tryptophan in the brain and the
degree of mental fatigue. Upon entry into the brain, tryptophan has the ability
to "calm" the central nervous system, causing sleep and drowsiness. Normally,
there are sufficient amounts of branched-chain amino acids (BCAAs) circulating
in the bloodstream to control the entry of tryptophan into the brain. During
long-term and sustained exercise, however, muscles use large amounts of amino
acids as a source for energy. The body prefers to use BCAAs for energy, since
they readily replace glucose in the energy production pathways. As muscles begin
to use BCAAs, the amounts of these amino acids drop, which allows tryptophan to
enter the brain, inducing fatigue and tiredness. Research shows that
supplementation with branched-chain amino acids can prevent central fatigue by
tightly regulating the influx of tryptophan to the brain. Supplementation before
and during exercise has been proven to enhance performance.
Branched-chain amino acids include leucine, isoleucine and valine. These
amino acids are needed for the maintenance of muscle tissue during physical
stress and intense exercise. From the perspective of athletes, BCAAs function as
agents and induce sparing, which allows the body to burn fat and not
muscle.
Nutrient needs often increase faster than calorie needs in athletes. Ultimate
