The world of sports Nutrition



Advances in medicine and an increase of capitalism in the world, and other factors all have contributed to the development of sports nutrition sector.




As scientists learned more on our bodies and the optimal level of physical fitness and strength, that they may harbor, businessmen jumped the gun and products and services that actually help athletes meet these optimal levels. media joined in ruckus and published materials leading to the promotion of science and the commercial side of the field.




Sports nutrition has been changing over the years around the world. It's not fair that the arguments are different – emphasis and approach have changed.




Peak Performance, a sports magazine conducted an article dehydration in runners October 1990, its inaugural issue. In this article from the benefits of water with those of glucose solutions that are more diluted, isotonic and therefore absorbed more quickly.




Today, go to almost any supermarket, shops and even school cafeterias and you'll find a ready supply of sports drink intended to maintain hydration only as glucose solutions.




The difference is that using glucose polymers llong soluble instead of glucose simple, you can now create an isotonic beverage moisturizer, which also supplies significant amounts of carbohydrates to working muscles. And the good thing is, sports drinks taste even better.




More than 10 years ago, was made public that muscle damage caused by free radicals can be reduced, taking antioxidant supplements of vitamins A, C and e. years after, antioxidant supplementation has become a standard in the world of sports nutrition.




Now, researchers are also beginning to understand that muscle damage is a more complex object.It is difficult to assess the damage of free radicals in athletes and was found that large amounts of nutrients, antioxidants actually can cause cell damage and hurt performance.




The technique of "loading coal" was widely used over the years by athletes from around the world.A diet rich in carbohydrates is important in maintaining muscle glycogen stores by ensuring high levels of resistance. However, in 1990 it became clear that the ' GI ' and the release rate of carbohydrates different was important influence on better when they must be consumed in relation to physical activity.




The ratio of carbohydrates and proteins were discovered also namely that carbohydrates promotes protein-sparing in the body.It was also discovered recently that consume carbohydrates before and during prolonged periods of strenuous exercise can help protect your immune system.




One of the most interesting recent developments in sport has been the rise of creatine supplementation. the use of creatine is now very common. Creatine renews the essential energy source or muscles, ATP adenosine triphosphate.Increased levels in muscles optimizes the turnover of energy means that you have more energy for exercise of high power and speed recovery during and after workouts. Creatine increases maximum effort of athlete, fatigue of delays and thus prolongs the resistance.




New wisdom and hence new products, surely have allowed athletes to fuel themselves better, work harder, more train and quickly retrieve. However, as in any type of innovation there will always be negative.




Dietary supplements available to athletes more in the 80 's were very straightforward. some athletes took drugs but erased the boundaries between supplements and medicines. Today, the race to find new formulas for increased performance has led to the availability of sports nutrition supplements that really do not occur naturally. the result is that the distinction between a nutrient and a performance boost substance has become increasingly blurred.




Some of these supplements contain ingredients that may cause athletes to violate the rules and regulations governing their sport due to accidental contamination by other, ' exotic ', substances present in the production environment of Supplement.




Further developments will be created in the world of sports nutrition and these will surely spawn ethical issues. "Nutrigenomics "— the relationship between genetics and nutrition — will be most wanted at the time.




As scientists become more qualified to discover the processes of our genes, will it be possible that, rather than adopting a general approach to sports nutrition, athletes from around the world will be genetically tested to help them determine precise individual requirements for optimal health.




In the coming years will predictably more exciting for the world of sports nutrition.
