CREATINE FOR ATHLETIC PERFORMANCE

The Advantages of Creatine for 
Enhancing Athletic Performance
If, about 5 years ago, you were to tell an athlete there was a supplement (which was not
an anabolic steroid or other bodybuilding drug) that would help bodybuilders and athletes
pack on as much as 10 rock-hard pounds of muscular bodyweight (which could lead to better
performance for athletes) in less then 2 weeks; increase their bench press by 25 lbs.
(which also would help in enhancing performance) in a mere 10 days; get a pump like you
were loaded on Dianabol(Phillips 48) (a pump that last for hours and hours which helps in
muscle development); and, all the while, help you run faster, jump higher, recover from
exercise more quickly, they would probably tell you to get lost. Well all these facts and
more have now been proven to be effective on athletes. Creatine is the safest, most
effective supplement out on the market today, says Ron Terjung, a physiology professor at
the University of Missouri. Millions of men are buying the dietary supplement, hoping it
is the magic pill that can transform them from scrawny to brawny. Creatine has made a
strong impact on the athletic world giving many an edge on the competition and enhancing
athletic performance.
The discovery of Creatine leads back to 1832. A French scientist named Chevreul,
identified a naturally occurring organic compound in meat and then was later found to be
manufactured by the liver, kidneys and pancreas using three amino acids. The scientist
named the compound Creatine after the greek word for flesh(Phillips 8).
Creatine is a compound that is naturally made in our bodies to supply energy to our
muscles. It is an energy rich metabolite that is found mainly in muscle tissue. It is
responsible for supplying the muscle with energy during exercise. Chemically, it is
called Methylguanido-acid. Creatine is formed from the three amino acids, argentine,
methionine, and glycogen that undergo a chemical process to form Creatine. Creatine is
manufactured in the liver and may be produced in the pancreas and kidneys. It is
transported through the blood and taken up by muscle cell, where it is converted into
Creatine phosphate; also called phosphocreatine. This reaction involves the enzyme
Creatine kinase that helps bond Creatine to a high-energy phosphate group. Once Creatine
is bound to a phosphate group, it is permanently stored in a cell as phosphocreatine
until it is used to produce chemical energy called Adenosine Triphosphate (ATP). ATP then
loses a phosphate group and becomes Adenosine Diphosphate (ADP). Creatine, when present
in the muscle in sufficient amounts donates a phosphate group to ADP and it rapidly
retransform to ATP, which is immediately available to the muscle to be used for a fuel
for exercise. During brief explosive-type exercises, the energy supplied to
rephosphorylate adenosine diphosphate (ADP) to adenosine triphosphate (ATP) is determined
largely by the amount of phosphocreatine stored in the muscle. As phosphocreatine stores
become depleted, performance is likely to rapidly deteriorate, due to the inability to
resynthesize ATP at the rate required. Since the availability of phosphocreatine stores
in the muscle may significantly influence the amount of energy generated during brief
periods of high intensity exercise, it has been hypothesized that increasing muscle
creatine through creatine supplementation may increase the availability of
phosphocreatine and allow for an accelerated rate of resynthesis of ATP during and
following high intensity, short duration exercises(Kreider 1). ATP is the primary source
of fuel for muscular exercise. It is used before sugars (carbohydrates) and before fats.
When muscles are used to lift weight, run or perform any type of work the ATP is broken
down to ADP (adenosine diphosphate) and energy is released. The amount of ATP stored in
the muscles will only fuel a maximum effort such as lifting a weight for 10 to 15
seconds. After that, the muscle must rely on Creatine Phosphate to restock its supply of
ATP. Increasing the muscles supply of Creatine phosphate helps increase the rate in which
the body can supply ATP. This increases the muscle capacity to do work and improves the
energy level of the muscles.
Typically, the average person metabolizes about two grams of Creatine per day, and the
body normally synthesizes that same amount; thus, you generally maintain a Creatine
balance (Bamberger 59), but it is not uncommon for an athlete to have what is called
Creatine deficiency.(Phillips 15) which is not being able to create enough Creatine on
your own. In these cases through a more balanced diet or by supplementing Creatine in
their diet they regain the balance. This leads to a point that proves in one way how
Creatine has an advantage on enhancing athlete's performance. 
Creatine is naturally found in foods. For example, the average helping of beef or fish
contains about 1 gram of naturally occurring Creatine. Unfortunately, Creatine is very
sensitive to heat and cooking virtually destroys the effectiveness of Creatine. 
The amount of Creatine needed depends on the athlete's body weight and on the number of
days Creatine has been supplemented. Creatine should be loaded in relatively high amounts
for the first six days of supplementation and then may be taken in daily dosage while
maintaining positive performance. Creatine can bind water to the muscle giving an athlete
a more muscular appearance. Competitive bodybuilders usually drop Creatine
supplementation two weeks prior to a show to insure maximum definition and vascularity. 
Creatine has not yet been definitely linked to any adverse health effects, and thus has
very few side effects. One side effect usually caused by over-dosage which some have
complained about is stomach cramps. Reducing the intake of creatine in almost all cases
has reduced cramps to little or none. Although no adverse side effects have been reported
in the literature from clinical trials, concern has been raised by some physicians,
athletic trainers, and dieticians regarding: 1.) a possible suppression of endogenous
creatine synthesis; 2.) a possible enhanced renal stress/liver damage; 3.) anecdotal
reports of muscle cramping when exercising in the heat; 4.) anecdotal reports of muscle
strains/pulls; and, 5.) unknown long-term effects of creatine supplementation(Kreider
2-3). 
There are three theories today which answer the question, How do dietary supplements
work?(Phillips 13) The first theory is... when you have an adequate amount of a substance
that your body needs. Take Creatine for example, a human body normally only needs two
grams a day. That is the adequate amount or the minimum your body needs to stay healthy,
but lets say you stored five grams of Creatine, which is the maximum your muscles could
hold to give you a more optimal amount. The reason why an athlete would need more
Creatine is that they exert more physical activity and burn more ATP than a standard
person would. This makes him consume more body resources than the average person. So,
adding more Creatine to your diet would give you better results. The second theory states
that not all but most supplements have a mutating effect (Phillips 15). 1.) By volumizing
your cells to hold more resources then normal(15). 2.) Create a drug like effect on
cellular processes(15). With this scenario, the dietary supplement can exert a positive
effect on muscle metabolism and/or performance. The third theory and most important
relating to my paper states that a supplement might help you build muscle, enhance
athlete performance and improve your health by simply making up for the deficiency. This
has basically been what most dieticians, nutritionists, doctors, etc. have viewed
supplements as a means of protecting your body against vitamin and mineral deficiencies
and so on. Supplements have been widely used for decades as a means of preventing
serious, even fatal diseases, which are caused by nutrient deficiencies. Thus, proving my
topic by adding more Creatine to the bodies of an athlete can enhance performance by
replenishing the body with the most needed resources.
It is rumored that athletes in the former USSR and Bulgaria may have been using Creatine
to enhance athletic performance since the early 1970's. While this may be true, the
documented use of Creatine supplementation by athletes was with British track and field
competitors who competed in the 1992 Olympics in Barcelona. Creatine was given credit for
powering several of the British athletes who won gold medals. The London Times reported
(August 7, 1992) that Linford Christie, the 100meter gold medallist, supplemented with
Creatine before the 1992 Olympics, and a European magazine called Bodybuilding Monthly
reported that Sally Gunnele, the 400 meter gold medallist, also used Creatine. The London
Times also reported that Colin Jackson, the champion British 110-meter hurdler, used
Creatine before the Olympics (Bamberger 61). Shortly thereafter, U.S. champion athletes
began using Creatine. Since then, scientists have elucidated more secrets on how to best
utilize Creatine for optimal benefit. Now, champion athletes and bodybuilders around the
world swear by Creatine's effects. Now in the 90's Creatine has major use in all sport
categories, At least one quarter of all major leaguers now use the substance. That number
is at least as high in professional hockey and basketball, and perhaps 50% of NFL Players
take Creatine. Among Olympic Sprinters, cyclists and weightlifters, those who do not use
Creatine are harder to find than those who do. Bodybuilders live on the stuff. Boxers,
too. Innumerable ordinary weekend athletes use it. It's everywhere (Bamberger 62).
When I was a sophomore in high school, I was first introduced to this miracle drug called
creatine. Many of the guys on the football team were taking this, and soon did I. I did
not really know what this white powdery substance was, but all I know is that it seemed
to jump my weight up 10 pounds within about three weeks. My weightlifting max's seemed to
be increasing and I was full of energy. Some of us would load just before a football game
to give us that extra boost of energy. To us, it seemed like legal steroids with no side
effects. Creatine seemed to improve performance for short-duration activities like our 40
times, bursting off the snap of the ball, and our weightlifting max's. What I found was
in order to make creatine effective, you must work out at least three times a week
consistently. Most people do not notice any difference until about three weeks into the
cycle. A recent study followed 19 men who lifted weights regularly over 12 weeks. Those
taking creatine registered an average 6.3 percent gain in fat-free body mass, compared
with a 3.1 percent gain in those not taking the supplement(Timberline 1). 
In 1981, an article published in the New England Journal of Medicine by Dr. l. Silila.
Reported that supplementation with Creatine in a group of patients suffering from a
condition called Gyrate Atrophy (a genetic ailment of the eyes caused by a metabolic
inability to efficiently metabolize ornithine and synthesize Creatine). Improved the test
subject's strength, increased their bodyweight by ten percent, and partially reversed the
Type II muscle fiber atrophy associated with this disease(Silila 867). One athlete in
this group of test subjects improved his best time in the 100-meter sprint by two
seconds.
In 1993, a study peer reviewed and published in Scandinavian Journal of Medicine, Science
and sports (Balsom 143) demonstrated that Creatine supplementation could significantly
increase body mass (in only one week) and that it was responsible for improved
performance in high-intensity intermittent exercise.
Over the past 4 years, at least 20 separate university studies have demonstrated that
Creatine monohydrate supplementation increases athletic performance; strength;
recuperation; speed in the 100-, 200-, and 400-meter sprints. A lot of factual,
scientifically proven data shows Creatine monohydrate works. It produces fast and
significant results even in the most rigorous trials(Casey 31). 
The goal of the bodybuilder and most athletes is to use progressive resistance exercise
to force the muscles to adapt and grow in size and strength. This increased workload or
progressive resistance can be achieved in several ways: by increasing the force of
contraction through increased resistance such as when lifting a heavier weight, by
increasing the duration of time that the muscle is under tension or contracted, and by
increasing the frequency of exercise.
Creatine helps in all three ways: it helps build lean body mass which allows still
greater force to be used; provides energy so the duration of exercise or work can be
lengthened; and speeds recovery, so exercise frequency can be increased. I have also
personally benefited from the use of Creatine. I have benefited from all of the above,
but have also gained more personal respect and confidence for myself from the results I
have accomplished with the use of Creatine.
