Those that play high intensity sports such as soccer understand that they must be kept hydrated in order to perform. Researchers wondered whether or not water or a carbohydrate solution was better to enhance performance. A study was done to see whether water or a carbohydrate solution provided the best hydration. The analysis showed that a carbohydrate solution improved soccer performance more than water alone. It provided the players with a longer period of maintained agility as well as focus.

Commercial hype poses a huge problem when trying to address the validity of a product. The most recent craze is the mangosteen fruit. The fruit is loaded with antioxidants and xanthones and a lot nutritional value to you. The recent craze is driven from the fact that this fruit has about 40 xanthones which are thought to have medicinal characteristics. This is the ultimate driver for this fruit.
The company Xango is the main marketer of mangosteen, which sells it in juice form. The juice is not reasonably price at 37 dollars a bottle and for what it offers might make one wonder if it is worth it.
Many of the company’s claims are not of fact but rather beliefs. They claim their product: maintains intestinal health, supports the immune system, neutralizes free radicals, helps support cartilage and joint function, and promotes a healthy seasonal respiratory system. All of these claims are supposedly been heavily researched, however after a search on the fruit in peer review journals, I was unable to find their supporting evidence. The research that they claim was done by them, which makes it fairly biased. In fact of the 40 xanthones, they have only really studied 6 of them. In the future it might turn out to be a very medicinal fruit but as for now it has yet to be scientifically proven.
So in an essence the reason that people are so gun ho about Xango is because they stand to make a profit from selling it. They market it like it is the miracle cure all fruit. Sellers rely on people’s worries and fears about their health.
So really the juice is not bad for you but it just has not been proven to do what it claims… this is the essence of the problem, is it worth 37 bucks for a bottle of juice that’s not been accepted in the scientific community… I think not
One of the worst consequences of exercising is muscle soreness. This can leave a beginning athlete sore for several days and kill their motivation to continue. Nutritional supplementation with Branch Chain Amino Acids may provide relief.
Protein is an essential part of our daily diet. The building blocks of protein are amino acids. There are two types of amino acids, those the body can build from other amino acids (non-essential amino acids) and those it must receive from the diet (essential amino acids). Branch-chain amino acids (BCAAs) are essential amino acids. BCAA supplements provide two main advantages, a quicker recovery from exercise and a stronger immune system. Two recent studies demonstrated that when BCAA’s were supplemented to the diet of athletes performing intense exercise post-exercise muscle soreness was reduced. While exercise has many health benefits, it does put a strain on the body’s immune system. Glutamine (an amino acid) the powerhouse of the immune system, increased significantly in those that received supplemented BCAA’s.
