There are three classifications of sports drinks. These are isotonic drinks, hypo-tonic and hyper-tonic drinks. Each one has different levels of glucose, electrolytes and carbohydrates. The most efficient source of energy, which is stored in the muscles and liver are carbohydrates. During exercise and heat, the body can lose 3-4 grams of carbohydrates per minute.
The electrolytes that the body loses during sweating include sodium, potassium, calcium, magnesium, chloride, bicarbonate, phosphate and sulphate. Large losses of these electrolytes can result in dehydration and heat stroke, both of which are dangerous and can be life threatening.
When choosing drinks for hydration and replenishing the loss of electrolytes, choose according to the exertion and sweating that occurs. For example, isotonic drinks contain fluid, electrolytes and 6-8% carbohydrates. Hypo-tonic drinks contain fluids electrolytes, but a low level of carbohydrates. Hyper-tonic drinks contain a very high level of carbohydrates along with fluid and electrolytes.
Many of these are considered healthy drinks because they include vitamin e, b vitamins, electrolytes such as sodium and potassium. Many of these healthy drinks also contain large amounts of high fructose corn syrup.
Reading the label before purchasing a healthy drink will allow the buyer to determine which one is the best choice for them. Other health conditions may have reactions to some of the ingredients and that should be taken into consideration. Research on a isotonic, hypo-tonic or hyper tonic or other healthy drink can help make the choice easier.
There are healthy drinks that are alternatives for these electrolyte replacement drinks. Coconut water and juices with natural sugars, like orange and pineapple, can hydrate just as well as some of the advertised healthy sports drinks. By adding just a pinch of salt, these juices will supply the energy boost desired and a healthy dose of vitamin C.
Other healthy alternatives include green and black tea, which contain less caffeine that most of the healthy sports drinks available. Just remember to read the labels and ingredients in order to make the healthiest, wisest choice in re-hydration and electrolyte replacement drinks.
