Are Sports Drinks the Answer?

It is undisputed that fluid and carbohydrate replacement is critical for optimal sports performance. Sports drinks manufacturers promote that the consumption of their products is necessary way to achieve this aim. However, long term dependence on sports drinks for fluid and carbohydrate replacement may not be the most suitable approach for many athletes.

There is an ever-increasing supply of research that implies that appropriate fluid intake is needed for optimal sporting performance. It is often suggested that a sportsperson may experience thirst only after a 2% weight loss ascribed to water but this amount of dehydration can diminish sporting performance by up to 30%.

For this reason, the sports drinks containing both carbohydrates and minerals have become ubiquitous. Studies show that water is most swiftly absorbed from the stomach when it contains around the same level of components as that of blood when it is referred to as isotonic. Normally sports drinks consist of around 5-8% of carbohydrate, which is considered to be around the optimal level for fastest rate for replacement of fluids. Drinking an isotonic sports drink will replace the lost fluid more rapidly than plain water but will also provide carbohydrate energy and necessary minerals (depending on the make up of the sports drink).

Drinks that with a concentration of more than 8% carbohydrate are often claimed to be more likely to result in upset stomachs.

Regardless that sports drinks have been around for quite a few years there is still some disagreement about how beneficial the use of the drinks is. Some of those who are against the regular use of them observe that some of the more favourable research is supported by those making and selling the sports drinks. However, it is probably valid to conclude that following the normal guidelines for consumption of the drinks may lessen the likelihood of underperforming. Yet during long distance sporting events (or training) in warm or humid weather simply drinking sports drinks with no consideration of the amount of carbohydrates consumed may actually lead to problems.
