Replenishment of Electrolytes
Electrolytes are salts that are naturally part of body fluids. When an athlete (or a gardener or a mail carrier or anyone else who engages in physical activity) sweats, electrolytes are lost through the sweat. If electrolytes are lost too quickly, the body does not have the ability to restore them as rapidly as they were lost. Sports drinks contain electrolytes such as chloride, sodium, and potassium to help replenish what was lost through sweat. Introducing electrolytes back into the body helps keep dehydration from occurring. Dehydration can become a very serious problem if not attended to. Electrolytes help to increase the absorption of fluids into the bloodstream.
A person who is exerting energy can quickly become dehydrated, in as little as 30 minutes. Therefore, it is suggested that athletes begin drinking a sports drink even before they start their activity.
Replenishment of Energy
Anyone who has ever exercised knows that fatigue can occur quickly. One of the reasons for this is that exercise increases metabolism, and when a person's metabolism is working overtime, it breaks down carbohydrates quickly. Carbohydrates are one of the main sources of energy for the body.
By replacing lost carbohydrates, the body can continue to work efficiently and an athlete has more energy to complete their activity.
Replacement of Lost Vitamins and Minerals
The human body also draws energy from various vitamins and minerals only found in certain foods, beverages or supplements. Sports drinks contain these vitamins and minerals to help keep the body working efficiently during activity.
Quenching of Thirst
As the body loses fluids, a person who is exerting energy will become thirsty. The ingredients found in sports drinks can quench thirst as effectively as water and better than soft drinks leaving the person feeling more refreshed and energized.
The Right Balance of Ingredients
In the past, many athletes created their own energy/sports drinks. Some still do. However, a sports drink that has a proper balance of ingredients will be much more effective than a homemade version. Most commercial sports drinks have the correct balance of electrolytes, carbohydrates, vitamins, minerals, and liquids. Without the right mix of ingredients in the proper amounts, a sports drink could hinder instead of enhance performance. Upset stomach or poor absorption rate of the drink could occur from the wrong balance of ingredients.
