Body
Building
Supplements
Bodybuilding supplements consist of a number of different
substances used by athletes or individuals participating in a variety
of
physical activities, including weight training. Their purpose is to act
as an
aid in the building of lean muscle mass or to facilitate the loss of
fat. Such
supplements can be helpful by improving sporting performance and
facilitate
recovery from events and training. However, their potential effects are
the
subject of some debate.
Weight
training is a common form of strength training (which
refers to the use of
opposition to
muscular contraction to generate the strength, anaerobic endurance and
ultimate
size of muscles). It employs gravitational force (by the
use of weighted
bars, dumbbells or weight stacks) to counter the force produced by
muscles
through concentric (which is
a form
of muscle contraction whereby the muscles tighten up whilst generating
force)
or eccentric contraction (in which
the muscles extend whilst under tension as a result of an opposing
force
exceeding that generated by the muscle). Weight training
employs a
number of specialised pieces of equipment to focus on specific muscle
groups or
types of movement.
Bodybuilders
often consume a powdered form of protein, which
is an essential constituent in the muscle-building process. Protein milkshakes, made from
protein powder and
milk, are a popular bodybuilding supplement. Protein
powder is normally
consumed either just before or after exercising, or instead of a meal.
The
generally accepted role that protein plays is that it allows for the
efficient
growth and repair of muscle tissue.
Some
of the most important sources of protein include the
following:
Whey
Protein – It consists of a
mixture of globular proteins (which are one of the three main protein
classes, consisting of "globe"-like proteins that are fairly soluble
in water) isolated from whey, the liquid that remains once milk has
been
curdled and strained, and created as a by-product of cheese production.
It is the most commonly
used form of protein, and is
absorbed by the body easily and almost immediately.
It contains high levels
of: (a) all the essential amino
acids (there are eight amino acids that are essential for humans.
Since the body does not synthesise
them, then
they must be included in the diet in order to obtain them), and (b) branched-chain
amino acids (the
combination of the
three essential branch-chain amino acids leucine, isoleucine and valine
constitutes around 1/3 of human skeletal muscle, and is important in
protein
synthesis).
It has the
highest content of the amino acid cysteine (which can be synthesised by
the
body) and is important in the biosynthesis of glutathione which helps
to
increase the bodies immunity (as an antioxidant, glutathione protects cells from reactive
oxygen, such as free
radicals and peroxides).
Hemp – It is one
of the earliest-known plants used in a domestic environment. Hemp seeds
contain
all the essential amino acids and fatty acids that are required to
sustain a
healthy body. Furthermore, the seeds contain around 20% of an easily
digestible
protein. Hemp oil is an edible oil containing around 80% of necessary
fatty
acids.
Egg
- Egg white protein is a lactose- and dairy-free
important source of protein.
