Creatine: A Literature Review

Improved Essays
The multi-billion dollar industry of nutritional supplements is like a wagon that is continually fueled by apocryphal advertising, fallacious claims by its manufacturers and distributors, along with a little dose of pseudoscience passed around in the gymnasiums without much foothold on factual scientific evidence. This has given rise to a lot of misinformation surrounding several nutritional supplements chiefly associated with weight loss, weight gain, athletic performance, sexual performance, hair loss etc.
In the case of creatine, it has been well established that increasing creatine availability in the diet increases the total creatine and phosphocreatine concentrations in the muscle (Greenhaff, Bodin, Soderlund & Hultman, 1993). Moreover,

Nevertheless, this review of the literature focuses on the information presented in peer reviewed journals and government sponsored reports in the hope that these findings are based more on sound research and systematic analysis of the subject.
Creatine
The scientific terminology for creatine is methyl guanidine-acetic acid [NH2 - C(NH) - NCH2(COOH) - CH3]. Creatine monohydrate is a natural form of amino acid that is broken down into creatine phosphate in the body. Creatine phosphate integrates the vitality bearing molecule adenosine triphosphate (ATP). ATP provides vigor to all muscle contraction. The stored phosphocreatine and free creatine, make up what is known as your total creatine pool, which amounts to 120g in a 70-kg healthy individual (Balsom, Soderlund & Ekblom, 1994).
The Effect of Creatine on Anaerobic
…show more content…
Chwalbinska-Monteta (2003) conducted a study on elite male endurance rowers and observed a significant drop in blood lactate accumulation while exercising at lower intensities as well as a surge in lactate threshold after consuming creatine monohydrate (5 days 20 g/d). According to Vandebeurie, Eynde, Vandenberghe and Hespel (1998), oral creatine intake does not alter the ability to perform a long-lasting submaximal activity or VO2 levels and blood lactate concentration during a continous exercise and the recuperation post the exercise period. On the other hand, McNaughton, Dalton and Tarr (1998), demonstrated a significant enhancement of power output during 1.5 to 5 minutes of exhaustive exercise on a kayak ergometer due to creatine loading. The results of the studies concerning the influence of creatine supplementation on aerobic capacity are

    I have a friend that is taking creatine monohydrate for the effects of increased muscle endurance while he is lifting at the gym. He claims that the supplement he takes helps him grind out a few more repetitions on heavy weight. He also likes the water retention effect that happens to make him look a tad bigger than he really is. When I found out he was taking this supplement I decided to research it to determine if it was really beneficial to his health. He admitted that he had not really researched the supplement, but instead he just read that the label said it was going to help him lift more weight at one time.…

    At present, creatine monohydrate is the most extensively studied and clinically effective form of creatine for use in nutritional supplements in terms of muscle uptake and ability to increase high-intensity exercise capacity. 6. The addition of carbohydrate or carbohydrate and protein to a creatine supplement appears to increase muscular retention of creatine, although the effect on performance measures may not be greater than using creatine monohydrate alone. 7. The quickest method of increasing muscle creatine stores appears to be to consume ~0.3 grams/kg/day of creatine monohydrate for at least 3 days followed by 3–5 g/d thereafter to maintain elevated stores.…

    The subjects of this test were given 5g of creatine a day, twice a day, for the first week. He called this “creatine loading”. “The patients were then limited to 3-5g of creatine once a day for the last 5 weeks.” (Shewmon, 2) The results from this experiment were very minimal as far as limiting muscle weakness and cramping, but it was an improvement. The symptoms addressed in this study are typical to the movements that a starting pitcher may face when he pitches due to the explosive movements that are required to perform the task of throwing a…

    The supplementation has now also become popular among recreational weight lifters (1,4). When performing short duration high intensity exercise, the majority of energy comes from the adenosine triphosphate (ATP) - phosphocreatine (PCr) system. PCr helps to increase the rate of rephosphorylation of ADP to ATP through the use of the creatine kinase reaction (1,2,3,4,5). As the exercise proceeds and the PCr stores are depleted, the performance levels are reduced as the ATP cannot be restored at the rate it is consumed (1,2,3,4,5). It is important to remember that there is a limited supply of these two substrates, therefore in order for the supplement to have a positive effect, it must increase the total creatine (TCr) and in turn PCr concentration (1,2,3,4).…

    What if all the exercise training in the gym brought little results due to one fixable problem with a simple solution? Muscle building is a substantial biological stressor that requires appropriate rest and proper nutrition. After a training session, nutrients are depleted from the body and needs to be restored for muscles to have the fuel to begin repairing and rebuilding. According to Schoenfeld and Aragon, timing is a known approach involving consumption of protein and carbohydrates before, during, and post workout trainings. The window of opportunity for refueling is within a thirty-minute time frame post-training (Placeholder1).…

    Creatine Phosphate Energy System This is an energy system your body will put to use in certain types of training. You start out with Adenosine Tri-phosphate (ATP) and when the energy system is put into action, a chemical reaction occurs where a phosphate (P) splits away and energy is released. You are then left with Adenosine Di-Phosphate (ADP). The CP system is generally used in short highly explosive training.…

    Use of creatine makes you body to consume Adenosine Triphosphate. ATP serves as a source of energy for your muscles. Thus, when you body has sufficient amounts of ATP it can be able to enhance the muscle function, this is one of the primary advantages of creatine consumption. Also, creatine is recommended by doctors, and thus it is a safe product for muscle building. Creatine refers to a component is made of amino acids that are commonly found within your body.…

    The process, once ingested, creatine is converted into phosphocreatine via a creatine kinase reaction. The newly created phosphocreatine donates phosphate to adenosine diphosphate (ADP) to resynthesizes adenosine triphosphate (Mangus & Miller 28). The ability to have phosphocreatine is vitally important because it is considered the limiting factor in the energy level your body produces as it works in short and long-term intervals that creates muscle growth and the ability to do your playing or training at the highest levels. There are downsides to every substance, and like any other, creatine has its negative aspects. For some people, weight gain would be negative, and for others, it may be a positive.…

    Exercise Physiology It has long been thought that strenuous or prolonged exercise can affect the human’s endocrine system. This is an interesting scenario because endocrine system synthase performs as a negative feedback system. This means that when there is an unusually high level of a hormone in the blood, a signal will be sent back and production of that particular hormone will be stopped. The negative feedback system can easily keep all hormones levels at the optimal level for humans.…

    Importance of energy systems involved in performance: During a soccer game, each energy system is applied with various intensities from low to high that are used. It can be hard to establish which energy system is used most frequently during a game of soccer for a defender. This is because there are many different movements performed with different levels of intensity that change throughout a game of soccer. For example, a defender will usually sprint and then stop, walk, jog and then sprint again in order to get the ball from the opposing team.…
