This ergogenic aid allows the athlete to train harder for
longer
Creatine supplements can help athletes to train harder - Tony Paladin explains how
Adenosine triphosphate (ATP) is a substance stored in one's
muscles, yielding instant energy through the cleaving of the phosphate bond
from an adenosine molecule. Stored ATP is, therefore, the only fuel capable of
generating 100% muscle contraction. Once ATP is exhausted, however, other fuels
dominate the energy supply, all of which are converted to ATP before they are
used (Carbohydrates, fats, proteins, and Creatine phosphate).
ATP
The average person stores enough free ATP for 4 to 5 seconds of
maximum muscular contraction: enough to do one squat, throw a javelin, or run 50
metres. Because it is the only way that one can ever put a maximum load on
one's muscles, muscle contractions fuelled by stored ATP are unquestionably the
most effective way of building strength. However, this is also the most
dangerous way to train as maximal muscle contractions carry the greatest risk
of ligament, tendon, and connective tissue damage.
Following 4 to 5 seconds of maximal exercise, a substance known as
Creatine phosphate (CP) becomes the dominant energy yielder, permitting near-maximal muscle contractions for another 5 to 6 seconds. This ATP/CP interaction
is anaerobic and uses no glycogen, glucose, fatty acids, or amino acids. Maximal
exercise extended past the five second ATP barrier into the CP system of up to 12
seconds (ATP+CP) becomes much safer as the amount of microtrauma is
significantly less than ATP alone.
As an adenosine phosphate molecule is removed (becoming an
adenosine diphosphate [ADP] molecule), a CP molecule immediately jumps into
action, donating its phosphate molecule to replenish the ADP molecule back to
an ATP, leaving a free-floating Creatine molecule. Following a muscle
contraction, most of the free Creatine and phosphate join up to regenerate CP.
This process, however, requires oxygen, which means that anaerobic exercise has
to be stopped to allow this to happen. Following maximal exercise, this process
takes about 5 minutes for 90% CP regeneration. This, therefore, means that for
optimal strength gains, the athlete should ideally wait 5 minutes between sets
before doing the next set - a long time!
Creatine
This is where Creatine supplementation fits in as it facilitates a
full load of Creatine phosphate in every muscle. It allows the athlete to train
harder for longer. The oral form of Creatine monohydrate is the most
digestible. The amount of intake depends on how much muscle there is to fill
and how much exercise the person does.
For an athlete to warrant taking Creatine, there should
be a minimum training load of 5 or more days a week and training maximal
resistance at a high intensity. Therefore, to reap any benefit from
Creatine whatsoever, the athlete has to train
HARD.
A recommended dose of Creatine for hard-training athletes is
approximately 0.1g/kg lean mass (lean mass is FAT-FREE mass, not total body
weight). Doses should be divided into smaller mini-doses that should be taken
before, during, and after exercise). Doses must be taken
with a sugar drink (such as fruit juice) and after a meal.
Doses should not be taken on an ongoing basis as there is evidence
of Creatine supplementation interfering with the body's metabolism over the
long term. Overdosing should also be avoided at all costs as excess Creatine
has been shown to interfere with the regulation of the kidneys resulting in
water retention.
In conclusion, young athletes do not need Creatine as the
only time benefit is gained with Creatine is during maximal resistance
training. Young athletes do not need this kind of training and therefore
no need for Creatine.
