Body building supplements in athletics

The Use of Supplements in athletics

Most student athletes are beginning to feel the pressure of expecting to be the best. In order for them to gain an edge on their teammates and other competitors, these athletes are taking many different supplements. Bodybuilding supplements are dietary supplements commonly used by those involved in bodybuilding and athletics. Bodybuilding supplements may be used to replace meals, enhance weight gain, promote weight loss or improve athletic performance. Some types of protein are to be taken directly before and after a workout, while others are to be taken before going to bed. However, creatine is mainly taken before a person works out. Among the most widely used are vitamin supplements, protein, branched-chain amino acids (BCAA), glutamine, essential fatty acids, meal replacement products, creatine, weight loss products and testosterone boosters.

Supplements are sold in different forms. Supplements are sold either as single ingredient preparations or in the form of "stacks" - proprietary blends of various supplements marketed as offering synergistic advantages. Most supplements can be found in local sports shops or in local nutrition shops. Some supplements can be found in grocery stores as well. The annual sales of sport nutrition products in the US are over $2.7 billion (US) according to “Consumer Reports”.

The most commonly used supplement on the market is protein powders and protein drinks. The know benefits of taking manufactured protein is the extra help to gain muscle. If used correct, protein drinks can help gain muscle 10 percent faster.  The theory behind this supplementation is that bodybuilders, by virtue of their unique training methods and end-goals, require higher-than-average quantities of protein to support maximal muscle growth. Currently, no consensus has been reached in determining whether or not an individual in exercise training can benefit from protein and amino acid supplements. Protein supplements come in various forms: ready to drink shakes, bars, bites, oats, gels and powders. Protein powders are available in a variety of flavors. Although it is generally undisputed that athletes and bodybuilders need an increased intake of protein, the exact amount is highly individualized and dependent on the type and duration of the exercise as well as the physiological make up of the individual. Age, gender, and body size may vary this protein intake. Some health experts, however, have criticized protein shakes as being unnecessary for most people that consume them, since most users already get enough protein in the normal varied diet with enough calories. However, there is some evidence to support the idea that protein shakes are superior to whole foods with regards to enhancing muscle hypertrophy in the one hour window following intensive exercise. Moreover, for athletes who do not have the time to prepare whole food meals on the run or immediately after exercise, a protein shake may be preferred for practical as well as performance reasons. Additionally, some studies suggest low-calorie dieters, vegetarians, haphazard eaters and those who train very heavily may benefit significantly from protein supplements. Traditional nutrition theory states that the body can only metabolize 5-9 grams of protein per hour and that excessive daily intake can cause weight gain, kidney problems, osteoporosis, or diarrhea. However, many bodybuilders report consuming hundreds of grams of protein per day to achieve maximal strength gains, so this nutrition dogma may only apply to the general public. Taking an overdose of protein can lead to a loss of appetite, which may be useful for some dieters. Nutritionists claim that osteoporosis occurs from excessive protein intake because protein can put pressure on the kidneys and lead to bone loss due to calcium leaching. There are three branched-chain amino acids (BCAAs): leucine, isoleucine, and valine. Each has numerous benefits on various biological processes in the body. Unlike other amino acids, BCAAs are metabolised in the muscle and have an anabolic/anti-catabolic effect on it. BCAAs account for 33% of muscle protein. Glutamine is the most abundant amino acid found in human muscle and is commonly found in supplements or as a micronized, instantly soluble powder because supplement manufacturers claim the body's natural glutamine stores are depleted during anaerobic exercise. Serum glutamine is used by the body to counteract the acidosis that results from exercise; in order to replenish the loss of glutamine from the bloodstream, the body catabolises glutamine from the muscle. Ingestion of supplemental glutamine may therefore help ensure a ready supply for the muscles. It is also argued that a deficiency may lead to a weakened immune system and wasting of muscle tissue. Creatine is an organic acid naturally occurring in the body that supplies energy to muscle cells for short bursts of energy (as required in lifting weights) via creatine phosphate replenishment of ATP. A number of scientific studies have shown that creatine can improve strength, energy, muscle mass, and recovery times. In addition, recent studies have also shown that creatine improves brain function and reduces mental fatigue. Some studies have suggested that supplementation with the ergogenic caffeine may eliminate the beneficial effects of creatine. This is significant because both creatine and caffeine are viewed as excellent supplements by body builders, and it was hypothesized that the combination would lead to rapid strength gains. The negative effect of caffeine on creatine metabolism is still questioned, however, and begs for further research.

Although there are some proven pros of body building supplements, the fact is that they are not a necessity. Manufactured protein and creatine and other supplements can lead to future problems affecting your play. The is no need for body building supplements.
