Actions And Effects Of Creatine Essay, Research Paper


Throughout time,


humans have had a fascination with being excellent at what they do, and


athletics have been no exception. Many substances exist, and many have been


criticized and analyzed for their safety, legality, and morality for athletes.


With the banning of steroids from competitive sports, and the implementation of


random drug testing in most sports, most athletes, professional, recreational,


and would-be professionals are hoping to gain an edge. More recently, one such


edge has been discovered, and it has found itself in locker rooms across the


country, in the hands of these athletes, and all the while, and probably more


importantly, in the media’s direct line of fire. Although legal, creatine has


it’s proponents and it’s opponents, through this paper, I’ll discuss some of


the factors that make creatine such a hot topic in sports and the health


industry. To understand why people use creatine, we must first understand what


it is. Creatine is a naturally occurring nutrient that is found in the body


(Sahelian, 2000). It is also found in meat and fish, usually at a concentration


of about 4 grams of creatine per kilogram (Sahelian, 2000). As a general fact,


we consume around 1 gram per day from out daily diet. Vegetarians have a much


lower intake of creatine than most meat eaters, and will usually have a noted


reaction to creatine supplementation due to this fact (Sahelian, 2000). To


apply creatine to the muscle building process, we must understand what it does.


When we use our muscle everyday for any activity, we use oxygen to make energy.


This energy is created by breaking down a chemical that exists in our body


known as adenosine triphosphate (ATP), into another chemical, adenosine


diphosphate (ADP), but using oxygen to make energy is a very slow process


(Sahelian, 2000). This is the part of the process where creatine makes itself


known. Current studies show that creatine supplementation can increase the


amount of creatine in muscles, which in turn, speeds up the ATP refueling


process (Murphy, 2000). This enhances performance by producing more energy for


brief, high-intensity exercise such as sprinting, and allowing for more


strenuous workouts (Gutfeld, 1997). All of these factors are crucial to


athletes who are searching for their legal "magic bullet". Creatine


was first discovered by a French scientist in 1832 (Bamberger, 1998). This


scientist discovered a naturally occurring organic compound that could be


produced by the kidneys, liver, and pancreas. The compound was named


"creatine", the Greek word for flesh (Bamberger, 1998). It has been


found that most people consume 1 gram per day, along with naturally producing 1


gram (Bamberger, 1998). In 1981, the potential medical benefits of creatine were


published in the New England Journal of Medicine in, seven years later, two


Swedish doctors, Paul Greenhaff, and Eric Hultman, recorded


performance-enhancing effects of creatine in athletic subjects, and their


results were published in the journal Clinical Science in 1992 (Bamberger,


1998). Most of the current creatine "buzz" surfaced and intensified


after the 1992 Olympics when several athletes such as runner/sprinter Michael


Johnson, reported using creatine to prepare themselves for the games. In more


current trends, exact numbers regarding athletes who use creatine do not exist,


but when Brady Anderson, a professional baseball player and creatine


user/endorser began supplementation, he was one of very few who knew about the


product, but numbers suggest now that approximately 50% of all NFL players use


creatine (Bamberger, 1998). Creatine is most commonly used by athletes of all


kinds, namely recreational, high school, college, and the more scrutinized


professional athletes. These athletes use creatine because of what creatine


supplementation does. The reliable and valid research studies support the


benefits of creatine supplementation. Mainly, that it can have a positive


impact on the following aspects, 1) Expediting recovery between workouts, 2)


increase the amount of exercise that can be performed during workouts, 3)


increase muscle size and strength, 4) improve anaerobic power and endurance,


and 5) increase body weight (Arapoff and Riley, 1998). These are all very


attractive and positive factors that an athlete would love to be able to attain


legally, not compromising their safety with illegal substances such as


steroids, but through essentially, natural and relatively safe means. Luring to


some users are reports that results are quick and consistent, along with


increased muscle mass, and a prolonged pump during strength training (Sahelian,


2000). Although touted and highly regarded among some professional strength


trainers, there are some that are skeptical. For instance, the San Francisco


49er’s, have an estimated three quarters of the team using creatine, while the


Tampa Bay Buccaneers strength coach will not allow creatine in the Bucs’ locker


room (Bamberger, 1998). The creatine economy is booming, Experimental and


Applied S

ciences, have a stranglehold on the creatine market, since they were


instrumental in it’s introduction to the sports supplement arena, they have


such athletes as Shannon Sharpe as a paid user/endorser in EAS apparel at


public appearances, and this is a great way for them to increase exposure and


their marketability, along with having a phenomenal skyrocket in sales (Suggs,


1998). There is a simple explanation for the explosion of creatine, it’s


effective, legal, in most cases affordable, and it works. It helps muscles get


bigger and stronger faster, which is the basis of the strength-training regimen


of some athletes. The IOC or International Olympic Committee has not banned


creatine, and actually considers it a food, since it cannot realistically be


placed in the same categories of substances such as anabolic steroids, this


provided the ruling that it should not be banned (Nutrition Forum, 1999). The


form that is most likely and most commonly consumed is that of creatine


monohydrate in a white powder form, it comes in a canister or tub, and can be


purchased at stores such as General Nutrition Centers (GNC). A canister of the


EAS creatine has a price of roughly $60 (Bamberger, 1998). Creatine is usually


ingested in dosages of around 3 to 5 grams per day, and is recommended to be


preceded by a loading phase that consists of ingesting up to 20 grams a day of


the powder daily for 5 days (Gutfeld, 1997). This ensures that the muscles are


efficiently saturated with creatine. After this loading phase, a reduction to


the 3-5 gram a day dose, is recommended. Any more than what is recommended will


be excreted through the urine. Also, recommendations include ingesting the


creatine with a liquid that is high in carbohydrates. It is believed that the


high glycemic index will shuttle creatine into the muscle very quickly, and


have a higher absorption rate (Gutfeld, 1997). Also, users and researches alike


recommend checking the supplement is of high purity. Most manufacturers will


provide a laboratory analysis upon request (Gutfeld, 1997). Some users


question, what the best time of day to take creatine is, but reports show that


any time of day is acceptable, but most users chose to take it in the time


preceding their workout (Sahelian, 2000). There have been cases of


non-responders to creatine, but the reason is not known at this time (Sahelian,


2000). Some reported side effects of creatine include, loose stools, which can


occur with relatively small doses such as approximately 4 grams (Sahelian,


2000). Higher doses have side effects such as nausea, upset stomach, dizziness,


weakness, and doses in the 20 gram and above category have seen side effects


such as kidney damage (Sahelian, 2000). The reported feelings of dehydration


can be diffused by consuming large quantities of water, more than a gallon a


day (Bamberger, 1998). The result that is noted as most siginificant is that of


weight gain. This can be definitely a negative or positive aspect, considering


which sport the athlete is training for. For any sport where bulking up is


required creatine would provide an advantage, but any athlete trying to lose or


maintain weight will be offset by creatines reported effects. The American


College of Sports Medicine (ACSM), has issued a statement that although


creatine is an effective aid in performance enhancement, there have not been nearly


as many field studies as there have been laboratory studies conducted, also,


the ACSM notes that the jury is still out on the safety and effectiveness of


long term creatine use (Rose, 1998). Since there have been no studies conducted


about the long term safety of creatine, it is not currently recommended to


supplement for long periods of time, rather cycle creatine use, by stopping or


significantly reducing usage for a month’s time (Sahelian, 2000). Although the


long term consequences of creatine are not known at this time, it has, to this


point, proven to be safer than any illegal performance-enhancing aid, such as


anabolic steroids. Creatine supplemenation through a powder is also a viable


way to obtain the amount necessary to provide results. To obtain the


recommended dosage through our diet alone, one would have to consume anywhere


from 5 to 25 pounds of meat daily (Gutfeld, 1997). Someday, maybe creatine


research will conclude that it really is nature’s very own steroid. Bibliography
