BodybuildingBodybuilding supplements are dietary supplements commonly winstrol depot orally by those involved in bodybuildingweightlifting, mixed martial arts, and athletics for the purpose of facilitating an increase in lean body mass. The intent is to increase muscle, increase body weight, improve athletic performance, and for some sports, to simultaneously decrease percent body fat so as to create better muscle definition. Among the most widely used are high protein drinksbranched-chain amino bodybuilding supplements side effects wiki BCAAglutaminearginineessential fatty acidscreatineHMB and weight loss bodybuilding supplements side effects wiki. While many bodybuilding supplements are also consumed by the general public the frequency of use will differ when used specifically by bodybuilders. Athletes in ancient Greece were advised to consume large quantities of meat and wine. A number of herbal concoctions and tonics have been used by strong men and athletes since ancient times across cultures to clenbuterol use in australia to increase their strength and stamina.
Dietary supplement - Wikipedia
Creatine supplements are dietary supplements marketed as increasing high-intensity athletic performance. Creatine has no significant effect on aerobic endurance , though it will increase power during short sessions of high-intensity aerobic exercise. Creatine use is not considered doping and is not banned by the majority of sport-governing bodies.
However, in the United States , the NCAA recently ruled that colleges could not provide creatine supplements to their players, though the players are still allowed to obtain and use creatine independently. In the European Food Safety Authority EFSA published a record that stated that oral long-term intake of 3 g pure creatine per day is "unlikely to pose any risk". Both the American Academy of Pediatrics and the American College of Sports Medicine recommend that individuals younger than 18 years old not use creatine.
People with kidney disease, high blood pressure, or liver disease should not take creatine as a dietary supplement. Being a dietary supplement, it is advised that creatine should be taken under the supervision of a health professional.
Creatine taken with medications that can harm the kidney can increase the risk of kidney damage. It is advised to speak with your doctor or pharmacist before taking creatine if you are on these type of medications. Creatine has a fairly short elimination half-life, averaging just less than 3 hours, so to maintain an elevated blood plasma level it would be necessary to take small oral doses every 3—6 hours throughout the day.
Creatine supplementation appears to increase the number of myonuclei that satellite cells will 'donate' to damaged muscle fibers , which increases the potential for growth of those fibers. This increase in myonuclei probably stems from creatine's ability to increase levels of the myogenic transcription factor MRF4. CEE is a form of commercially available creatine touted to have higher absorption rates and a longer serum half-life than regular creatine monohydrate by several supplement companies.
However, no peer-reviewed studies have emerged on creatine ethyl ester which conclusively prove these claims. A study presented at the 4th International Society of Sports Nutrition ISSN annual meeting demonstrated that the addition of the ethyl group to creatine actually reduces acid stability and accelerates its breakdown to creatinine. The researchers concluded that creatine ethyl ester is inferior to creatine monohydrate as a source of creatine. As a supplement, the compound was patented, and licensed through UNeMed , the technology transfer entity of the University of Nebraska Medical Center.
Creatine nitrate is a nitrate salt form of creatine. No benefits have been noted except that it may be more water-soluble. Creatine gluconate is a form of creatine where the molecule is bound to gluconic acid. In , Harvard University researchers Otto Folin and Willey Glover Denis found evidence that ingesting creatine can dramatically boost the creatine content of the muscle.
The substance creatine is naturally formed in vertebrates. While creatine's influence on physical performance has been well documented since the early twentieth century, it came into public view following the Olympics in Barcelona. An August 7, article in The Times reported that Linford Christie , the gold medal winner at meters, had used creatine before the Olympics.
An article in Bodybuilding Monthly named Sally Gunnell , who was the gold medalist in the meter hurdles, as another creatine user. In addition, The Times also noted that meter hurdler Colin Jackson began taking creatine before the Olympics.
At the time, low-potency creatine supplements were available in Britain, but creatine supplements designed for strength enhancement were not commercially available until when a company called Experimental and Applied Sciences EAS introduced the compound to the sports nutrition market under the name Phosphagen. From Wikipedia, the free encyclopedia. For the biochemistry and physiology of creatine, see Creatine.
