Creatine (Cr) is a popular dietary supplement used by athletes to increase sports performance, muscle mass, and strength. Creatine was first discovered in “1835, when a French scientist reported finding this constituent of meat” (Demant & Rhodes, 1999). This organic compound is manufactured endogenously by the liver and kidneys “from the amino acids glycine, arginine and methionine” for energy stipulation during muscular contraction. (Arazi, Rahmaninia, Hoseini, & Asadi, 2011). Creatine is either converted into free form Cr or phosphorylated form as known as creatine phosphate (CP). The endogenous production and exogenous consumption of Cr yields about 1 gram a day for the average person (Cooper, Naclerio, Allfrove , & Jimenez, 2012). In …show more content…
The biological value in whey protein enhances the body’s ability to absorb essential amino acids after resistance training decreasing the athlete’s recovery time. When athletes combine whey protein and creatine monohydrate they expect “a greater increase in lean tissue mass and muscular strength than supplementations with whey protein alone” (Burke, Chilibeck, Davison, Candow, Farthing, & Smith-Palmer 2001, p 350). Exogenous Cr supplementation increases the body’s Cr levels until saturation occurs. This saturation of Cr increases the PCK shuttle continuum allowing training intensity, volume, and duration of the exercise the athlete is performing to continue at a maximum rate. Any excess Cr in the blood is cleared through sweat, urination or renal filtration. Measurements in strength and peak torques of athletes supplementing with whey protein and creatine monohydrate (WC), whey protein (W), and a placebo (P) were taken. According to Burke et al, (2001) “repeated measure analysis of variance was used to assess changes in body composition, strength, and peak torque for the three groups (WC vs. W vs. P) across time” (p. 354). A twelve week strength training program was constructed and consisted of a “4-day split routine involving whole body musculature” (Burke et al, 2001. p 352). Subjects used detailed training logs to compare progress over the 12 week experiment. The end result from this experiment shows that subjects who “supplemented with both creatine and whey
Creatine is a very controversial supplement on the market today. Many endorse the uses of creatine, but others are skeptical about the advantage a person receives from taking it and the dangers one inherits as a result of creatine consumption. The debate remains due to the short amount of time that creatine has been available. People base their opinions on preliminary studies that have been done but no one knows the long-term effects of creatine on the body. Many take the risk without vast knowledge, but others still remain skeptical based on preliminary evidence that discourages the intake of creatine.
With so many pre-workout supplements out there, trying to determine which ones are the real deal can feel overwhelming. Do you choose the most eye-catching packaging, or the most appealing flavour? Are you sure you’re getting the best value?
Pre-workout supplements are a newer category of products that are designed to increase workout intensity and energy. These products are being used by millions of athletes today, and there have been a lot of questions raised about the long-term effects of them. There are a lot of different brands in this industry, but most of the products contain the same main ingredients: Creatine, nitric oxide, vitamin B, and caffeine. There has been quite a bit of research done on these ingredients individually, but together they have not been studied very much, which is why a lot of athletes avoid them. Another problem with these products is that athletes are becoming
Creatine is a supplement, creatine is the most popular supplement for improving your performance. Many studies have proven it to be useful for strength, muscle mass and performance. Many people believe it is bad for you and your liver but there are no proven studies showing this if creatine is used correctly. Creatine is a natural substance found inside your muscle cells which helps you gain muscle in several different ways, raise anabolic hormones, boost work load, increase cell hydration, reduce protein break down, lower myostatin levels, improve cell signaling and help strength. Creatine also is 100% legal and is very effective for short term and long term muscle growth. Creatine can also help certain diseases such as Parkinson’s disease and Alzheimer’s. some people believe that creatine should be banned in sports and players caught using creatine should be punished, disqualified, or fined. This includes professional as well as semiprofessional and college athletes. These people believe that both the individual and team use of creatine should be illegal in sports. People who are for creatine believe that when used correctly creatine can be a healthy way to boost your athletic ability in a natural way. They believe creatine should not be banned and that players and teams should be allowed
Creatine phosphate has been heavily experimented upon to show that it is an important effector towards muscle activity. When creatine phosphate is present in a solution containing muscle fibers without the presence of ATP, it serves as the energy supplier due to the fact that it absorbs bound adenine nucleotide, which is firmly linked to the contractile elements on muscle fibers (Bozler, 1953). Even in low concentrations this nucleotide can be considered an energy transfer mechanism, for it takes full advantage of the creatine phosphates energy supply, thus acting as a substrate for the enzymatic activity of the contractile elements of a muscle group. Consumption of this nucleotide leads to an increase in the strength of contraction. Creatine phosphate also speeds up rate of relaxation of muscles, for it induces the relaxing effect of ATP (Bozler, 1953). Thus, this research suggests that creatine phosphate is directly linked to instigate muscle contractibility.
Creatine is one of the primary things an athlete will do to put supplements into their body. These supplements range from protein shakes to illegal anabolic steroids. Some sports supplements are incredibly safe and effective, yet others work for a while and then fizzle out, while others still work well but do more damage than good in the long run. In the past athletes had to turn to such things as anabolic steroids or blood doping (the process of taking out blood and adding oxygen to it and putting it back into your body in order to increase a persons endurance). However, these procedures have many drawbacks. Mainly, they are illegal. An athlete may be suspended from playing their perspective
Although creatine is fairly expensive (fifty dollars for a one month supply), the original results of creatine testing and usage were very positive. Creatine supplementation helps the body by increasing the amount of creatine in the muscles, thus enabli ng the body to put out more energy more quickly. It was first discovered in the early 1900s, before creatine supplements were available, that increasing dietary creatine in turn increases the amount of creatine in the muscles (Jenkins). Supplementation of creatine in the diet leads to even higher levels of muscular creatine. Research has confirmed this. Current data indicate that muscle creatine levels increase, on average, 20% after six days of creatine supplementation at twenty grams per day (Eichne r 76). This increase of creatine in the muscles in turn increases the body's potential for exertion. Once creatine supplements were tested in humans, those increases were
They measured muscular strength and anaerobic performance in trained athletes. 17 physically, active young men were selected for the study and the creatine group had 8 people and the placebo group had 9 people with average age of 23 and 26, respectively. The creatine group took 20 grams a day over the course of 4 servings and the placebo group received a carbohydrate mixture and both groups took it before meals. They trained on day 1 and 4, which included exercises that the whole body. They measured anaerobic power on a 30 second Wingate test, max bench press and squat, took blood and urine samples, and measured height, weight, and body fat. Using an ANOVA with repeated measures across time, the results demonstrated that there was an increase in anaerobic force (12%) and back squat quality (11%) when contrasted with the placebo group. With more creatine in the body than with the control group and the creatine group had lower body fat but more body weight because of increased muscle mass. Proper training and creatine led to power and force increases for these athletes, which is helpful to a running back in improving power, speed, and game
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.
In recent years, oral supplements of creatine monohydrate have become "increasingly popular among different athletes for use as a natural ergogenic aid (Stout et al., 1999). A surge in the use of creatine began in 1992, when "Harris et al showed that oral supplementation with high doses of creatine
Creatine is a nitrogenous organic acid that occurs naturally in vertebrates and helps tosupply energy to all cells in the body, primarily muscle. It is usually mixed with liquid and isdrank by people who are working out or doing some type of sport. Creatine increases the body’sability to produce energy rapidly. With more energy, you can train harder and more often,producing faster results. Also, research shows that creatine is most effective in high-intensitytraining such as weight training, football, and baseball. Performers and athletes shouldn’t be able to use creatine because there are many sideeffects and risks. The side effects of using creatine consist of kidney disease and failure, waterretention, nausea, cramping, muscle pain, and
Creatine monohydrate supplementation has been shown to result in an increase in skeletal muscle total and phosphocreatine concentration, increase fat-free mass, and enhance high-intensity exercise performance in young healthy men and women. Recent evidence has also demonstrated a neuroprotective effect of creatine monohydrate
Creatine is an organic molecule that is found in the human body as well as other vertebrate animal’s tissue (“Creatine”). It is considered an amino acid. Creatine is made naturally in the liver or can be taken as a supplement (“Creatine”). Creatine has shown that when taken as a supplement it has many benefits to the human body.
Creatine helps in increasing speed, power, and size of the muscles, strength endurance and tolerance to fatigue.
The scene is set. It is 2016 in Rio de Janeiro, and the final heat of the Olympics is about to commence. The sprinters have been training their entire lives for the opportunity at hand, and the outcome of the most important event of their lives is going to come down to mere milliseconds. With a gold medal on the line, these athletes will be looking for any advantage they can get, whether big or small. One direction these athletes turn for an advantage is supplements. Supplements have emerged as a way for athletes to increase their performance, yet their use is very controversial. Supplements, varying from simple multivitamins to complex chemical supplements, are used by almost every athlete, whether recreational or professional,
