Creatine1
Creatine is not an Herb, mineral, vitamin, hormone, or a steroid. It is also not those bread cubes that you scatter over your salad, either. Creatine is a natural nutrient found in our bodies and the bodies of most animals. Approximately ninety five percent is scattered throughout the rest of the body, with the highest concentrations in the heart, brain and testes. The human body gets most of the creatine it needs from the food or dietary supplements. Creatine is easily absorbed from the intestinal tract into the bloodstream. When dietary consumption's is inadequate to meet the body's needs, a limited supply can be synthesized from the amino acids arginine, glycine and methionine. This creatine production occurs in the liver, pancreas and kidneys. This is just a little bit about creatine and for my experiential component, I interviewed the weight training coach for LIU, Mr. Ken Tavani. Creatine is an essential player in the primary energy source used for muscle contractions. It exists in two different forms within the muscle fiber, as a free (chemically-unbound) creatine and as creatine phosphate. This later form of creatine makes up two-thirds of the total creatine supply. When your muscles contract, the initial fu
This lactic acid creates the burning sensation you feel during intense exercise. " The Saint John's University basketball program buys creatine for its athletes, while the Giants and Yankees leave it up to their players to decide whether it is safe for them. Scientists discovered creatine one hundred and sixty odd years ago, but only in the 1980's did they figure out muscle cells can be "loaded" with up to thirty percent more of the compound than they normally carry. There have been anecdotal reports that people in these sports may benefit. Cook, Grandjean, and Barnes at Texas A&M showed no significant effect on power output and fatigue when comparing a creatine ingesting group to a placebo group during exercise performed on a specially modified cycle ergo meter. It becomes a trade off between the increased strength you get from creatine and the increased muscle mass. Creatine users pack on fat-free pounds too, though no one is sure whether all the added mass is lean tissue or if some of it is water weight. Such questions talked about are, does the increase in creatine availability actually lead to higher phosphocreatine levels, and, does this translate to increased performance, and increase in strength, muscular endurance, and lower body mass? Over the past few years, studies have examined these questions, and received varying results. suggested that supplementation increases muscle creatine, but does not increase the level of phosphocreatine, which is the substance needed to increase energy. But if you keep on using ATP because of all the creatine you have, you can minimize the amount of lactic acid produced and actually exercise longer and harder. Creatine can also absorb intracellular water, thus resulting in a higher muscle volume. In one experiment, creatine-fueled subjects added an average of eighteen pounds to their bench press in less then one month. Athletes insist creatine works in any sport. If the amount of acid becomes too great, muscle movement stops.
