In the market, there have already been lots of sports nutritional supplements introduced. In spite of such diversity, they may still be classified into the following major categories: protein supplements, vitamin supplements, weight loss products, creatine, glutamine, and protein bars. Popular brand names are as follows: Xendadrine EFX, Hydroxycut, Muscletech, EAS, Twinlab, Optimum Nutrition. Food preparation can become a challenge but it is a challenge that athletes need to face since good sports nutrition help to adequately fuel work-outs and improve performance and recovery. Eating well should be a part of an athlete s overall training plan. But buying well is a requirement for eating well. For girls with ages twelve to fifteen, they must have at least one thousand milligrams of calcium per day. For teenagers with ages sixteen to eighteen, on the other hand, should have a normal calcium intake per day, which is eight hundred milligrams. For women who are having their menstrual periods, they should also take eight hundred milligrams of calcium a day. Sports Nutrition And Athletic Health To those who do not know, it is quite a pleasure to announce that sports nutrition health is extremely detrimental to an athlete s performance. Why detrimental? This is what drives athletes to prioritize their health and maintain a healthy lifestyle to be able to excel in their sport. The Best Sports Nutrition Before A Competition What is the best sports nutrition for an athlete? There is no definitive answer to this. No athlete has the same need. It all depends on the physique of an athlete and the kind of sports that he or she is into. So, if you are contemplating on joining an endurance sports competition, the best sports nutrition for you is the nutritional table fit for an athlete that expects long hours of vigorous physical activity and mental alertness even when tired. However, in the 1990 s it became clear that the glycaemic index and release rate of different carbohydrates had important influence on when they should best be consumed in relation to physical activity. The relationship of carbohydrates and proteins were also discovered namely that carbohydrates promote protein-sparing in the body.
