Creatine
What evidence is given for Creatine scientific or testimonial?
The evidence I will provide is strictly scientific, the information comes from the Journal of Sports Nutrition. The article is written by Richard B. Kreider, Exercise & Sport Nutrition Laboratory Department of Human Movement Sciences and Education The University of Memphis. The author has many credentials, such as his testing of finding the effects of six weeks of creatine monohydrate supplementation in male and female track athletes, which can be found in the Journal of Strength and Conditioning. All of his research is peer reviewed.
Does the experimental testing of Creatine answer all questions asked such as will Creatine increase mass and strength? Was a double blind placebo used? What Methods were used? What dosages was the group given? How long was the testing?
The purpose of this study was to examine the effect of creatine supplementation in conjunction with resistance training on physiological adaptations including muscle fiber hypertrophy and muscle creatine accumulation. METHODS: Nineteen ...
One of the largest issues with the investigation was that, although the sample size of twenty would be considered good for many experiments, in this experiment it was far too small a sample to represent the rate of muscle fatigue for humans as a species.
Good nutrition and its role in positively affecting athletic performance has become more and more evident almost daily. Specific macro and micronutrients are better understood as to their specific functions within the body and from that how they can influence the body’s ability to perform while under duress. An example of such would be the stress of athletic performance. Vitamin D, which is also referred to as cholecalciferol, is one of the fat soluble vitamins that have been attributed to influencing athletic performance. However, vitamin D is not as much a “performance enhancing” nutrient in the sense that when taken in higher amounts it will aid athletic performance, but rather when in deficient amounts it can hinder athletic performance.
Creatine is one of the most popular sports supplements on the market and is used by bodybuilders, and athletes. It is an amino acid, like the building blocks that makes up proteins. It is also an important store of energy in muscle cells. Creatine is a natural nutrient found in our bodies and in the bodies of most animals. It can also be found in the form of a powder and sold as a supplement. Creatine is categorized as a food supplement by the Food and Drug Administration, like a vitamin and is available over the counter at drug stores and nutrition centers. Approximately 95% of the body’s creatine supply is found in the skeletal muscles. The remaining 5% of creatine is scattered throughout the rest of the body, with the highest concentration in the heart, brain, and testes. The human body gets most of the creatine it needs from food or dietary supplements.

The problems with performance enhancing drugs are that they give the user unfair advantages over other athletes and come with many health risks such as baldness. Steroid use can result in very substantial legal consequences and can ruin the user’s reputation. There are many alternatives to steroids but not all of them are safe. Different organizations have different rules on steroids, but in most cases, the user can get suspended, fined, or even both. Various types of steroids can have various short-term or long-term side effects. There are several types of steroids, the most popular ones being anabolic steroids. Historically, steroids have been around for many years, but the debate surrounding them started recently, more specifically a few decades ago. An important term to know is anabolic steroids which are made to work with the user’s muscle mass. Another term to know is clarified by Ida Walker, author of the book, Steroids: Pumped Up and Dangerous, published by Mason Crest Publishers in 2008, defines, peliosis hepatis is a rare condition in which cysts filled with blood form in the liver, if the cysts were to pop then internal bleeding would occur. A positive argument about steroids is stated by Adrianne Blue, author of the essay, “Performance Enhancing Drugs Should Be Legal,” published in the book Athletes and Drug Use, published in 2009, disputes, “Blue concludes that legalizing performance- enhancing drugs can protect athletes from dangerously abusing them.” The utilization of performance enhancing drugs has left a giant scar on sports and has compromised the achievements of many athletes; therefore, they are transforming the sports world into a drug filled world.
Primarily lifters and athletes take creatine to get ahead of the competition. In an article written by Nancy Ling, she mentions how in the Olympic games from 1964-1994 Soviet Union powerlifters consumed creatine to get an edge on the competition and had great success from it. ("Creatine? Is It Worth the Risk?"). Also in the article, Nancy stressed the importance of taking the correct amount of creatine because it can help prevent kidney and liver problems. On the other side, consuming creatine can be dangerous if you are prone to having seizures, blood clots, or cardiac
Creatine serves as an energy reserve in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use.
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
Choosing a vocation can be a daunting task. With the world ever-evolving, one may come across a new attractive career every year. In order to ensure optimal job satisfaction, it is vital to educate oneself about every alluring prospect prior to committing. Simple factors like the time commitment and salary can mean the difference between a content existence and a miserable one.
Abstract: Since the beginning of sports competition, athletes have always looked for some kind of an edge over their competitors. They will do whatever it takes to be one of the elite and that includes injecting supplements into their bodies to make them bigger, stronger, and faster. Steroid use is probably one of the most common drug misuses in sports competition. Athletes found that with anabolic steroids one could become a better athlete twice as fast. Not until 1975 was the drug first banned from Olympic competition because of the health risks it produced. Shortly thereafter, the rest of the sports world did not allow anabolic steroids as well. With the use of steroids no longer permitted athletes began to look for other alternatives. On the rise is two substances called creatine and androstenedione, both of which are sold over the counter. These two performance enhancers have only had minimal testing done on them, excluding the long-term effects, simply because they haven't been around long enough. Creatine and androstenedione have been said to produce results like steroids without the side effects. The truth is they do produce side effects and irregular muscle growth. By banning the use of performance enhancing drugs, just like steroids, sports competition will have a much healthier and fairer environment to participate in.
In this day and age anyone can write anything and put it on the internet for everyone to read. You have to be diligent in separating fact from fiction. If you are skeptical you may have to do your own research to see where the information originated. Do not believe everything you read just because it states it was from a study as it may not be reliable or truthful. Both of these studies had interesting information, however since they both were lacking sufficient data it was hard to determine if the studies were completely honest and adequate or not.
Anabolic steroids are drugs containing, or hormone-like substances, that are used to increase strength and promote muscle growth. They were first developed in the 1930s in Europe to treat undernourished patients and to promote healing after surgery. Competitive weightlifters began using steroids in the 1950s as a way to increase their athletic performance. Use gradually spread throughout the world among athletes in other has been estimated that at least one in 15 male high school seniors in the United States--more than a half-million boys--has used steroids. Some are athletes attempting to increase their strength and size; others are simply youths attempting to speed up their growth to keep pace with their peers. In some countries, anabolic steroids are available over the counter. In the United States, a doctor's prescription is necessary.

Proteins are extremely important in the growth of muscles, combined with weight training; protein can enhance muscle mass gain. Dependent on the athlete, the balance between weight lifting and protein intake will vary; a professional or trainer will measure the needed amount. Thought, all athletes will need a high protein diet, short track sprinters will not intake as much as much as a football player, for the sprinter would have a high carbohydrate diet. Resulting in instant energy opposed to the football players need for muscle mass and stored energy for long exercise periods.
