Bodybuilding supplements

In the arena of athlete muscle performance, it is desirable to create conditions that permit competition or training at higher levels of resistance for a prolonged period of time. Athletes who participate in sports at any level, amateur or professional, strive to bring their bodies to a physical state which is optimum for the sport or activity of interest. One factor which enables athletes to participate effectively is a high degree of development of the aerobic capacity and/or strength of skeletal muscle. While exercise is one of the main mechanisms for achieving that goal, food and/or vitamin supplements, as well as pituitary growth hormone, are necessary for muscle growth. Exhaustive exercise depletes metabolic energy carbon sources and acutely disrupts skeletal muscle nitrogen metabolism. Dietary or food supplements are typically designed to compensate for insufficient or reduced levels of nutrients in the modern human diet. One particular goal in supplementing a diet is to increase or enhance the function of tissues such as muscle tissue. In the sporting and athletic community, food supplements which specifically improve athletic ability are increasingly important, such as supplements that promote or enhance physical growth or endurance, or reduce recovery time after exertion. Certain amino acids, including branched-chain amino acids (BCAAs), are released from muscle and are deaminated to elevate serum ammonia, oxidized locally as muscle fuel sources, and augment metabolic acidosis. Nine amino acids are known to be essential nutrients in the diet of healthy adults. Three of these essential amino acids are isoleucine, leucine and valine; they are termed the "branched-chain amino acids" (BCAAs) because they share a specific type of chemical structure. BCAAs have been known to stimulate protein synthesis in at least some skeletal muscles. The BAA produce this effect in liver as well. Branched chain amino acids can decrease protein catabolism, increase synthesis of hepatic and muscle protein, and serve as energy substrates for muscle tissues. Ammonia production may also be reduced when branched-chain amino acids are given as a substrate. Further, branched-chain amino acids can improve the nitrogen balance. There has been considerable interest among athletes in creatine, which occurs abundantly in skeletal muscle. Creatine plays a pivotal role in the regulation and homeostasis of skeletal muscle energy metabolism and it is now generally accepted that the maintenance of phospho-creatine availability is important to the continuation of muscle force production. Creatine may also be involved in other processes concerned with protein synthesis and hypertrophy of muscle fibres during training. The body-building industry has widely promoted the benefits of creatine supplements as a means of increasing body mass, strength and energy for reducing body fat. Once creatine enters the muscle fibers, it accumulates and stays there for several weeks. Thus, the strategy behind creatine supplements is to fill the muscles with the nutrient to capacity and then to take only an amount sufficient to keep the creatine stores full. Glutamine is known to be the major bowel nutrient and energy source and has been used to improve nitrogen balance, inhibit protein breakdown, stimulate the growth of epithelial cells, and reduce intestinal villous atrophy. Glutamine is an amino acid that promotes the release of growth hormone, which also increases strength and lean muscle mass. Glutamine also promotes better assimilation of nutrients and speeds up recuperation. Human growth hormone (hGH) is a protein hormone secreted by the somatotropic cells of the anterior lobe of the pituitary gland. HGH has a major role in the growth and retention of muscle due to its ability to promote cell division and proliferation in the body. It increases the amount of amino acids transported across the cell membrane, which provides the raw material needed for more protein synthesis. This gives the formula another mechanism to increase strength and muscle mass. Growth hormone even boosts the level of free fatty acids in the blood, resulting in greater use of fats as an energy source and the sparing of available proteins and carbohydrates. By raising the body's energy expenditure at rest, it works beneficially with creatine to help reduce body-fat levels. Food supplements for enhancing an athlete's muscle size and strength have become popular substitutes for steroids and other drugs in various sports and body building regimes. However, as athletes continually strive for improved performance, there is a continuing need for non-steroid containing aids for improving muscle size and strength. The steroid hormone testosterone is considered to be the male virilizing hormone. Its effects include maintenance of muscle and bone mass, sexual function, and psychological well being among others. Vitamins are organic substances that are essential in humans for growth and homeostasis. Vitamins are essential nutrients found in very small quantities in the body. These compounds play a key role in metabolism, growth and homeostasis and therefore are especially important in maintenance of body mass and the ability to effectively nourish the body are important for survival.
