What Sports Drinks Contain
Sports drinks are designed to replenish fluids, electrolytes, and sugars lost through sweating during exercise. They also contain vitamins and minerals. Some sports drinks even contain branched chain amino acids, and other ingredients which promote recovery.
Registered dietitians and competitive triathletes product test many sports drinks, searching for ones that deliver on their promises. Read on to find out what’s inside and whether your workout regimen warrants one.
Carbohydrates
A sports drink contains a combination of carbohydrates, electrolytes and fluid to improve hydration during intense exercise. They are usually consumed before, during, and after exercise in order to replenish energy, carbohydrate, and blood glucose levels. Ingestion of sports drinks also stimulates carbohydrate absorption and prevents the depletion or muscle glycogen. Both of these can have an impact on performance. A sports drink’s carbohydrate content should not be excessive, as it can cause intestinal discomfort or gastrointestinal distress. It is also important to consider the type of carbohydrates used in a sports drink, as some types are better absorbed.
To maximize the benefits of sports drinks, it is important to consume them in conjunction with a balanced and healthy diet. In general, a sports beverage should be consumed alongside water and not in place of it. This is because a sports drink was originally developed to help replenish the water, carbohydrates and electrolytes lost during intense physical activity, not as an alternative to water.
Electrolytes
A sports drink contains electrolytes, which have an electrical charge and are important for the body’s normal functions. These include maintaining blood circulation, nerve function, and muscle contractions. Typically, sports beverages contain sodium and/or potassium. Sodium is lost through sweating, while potassium is lost through urine. Some sports drinks also contain small amounts of calcium, magnesium, zinc and phosphorous. These are added as they can prevent cramps.
Most sports drinks have the same amount of electrolytes and carbs as the body. Most athletes can benefit from isotonic drinks after moderate to intense exercise. They can help replenish electrolyte levels that are depleted by sweating and improve exercise performance.
Gatorade’s popularity encouraged other beverage companies, including Coca-Cola and PepsiCo, to create their own versions. This led to a new generation with different ingredients and formulations. Several of these newer beverages feature natural sweeteners, including stevia and agave nectar. Others are labeled low calorie and some make a reduced-sodium claim. Some, such as Code Blue and G2, are designed for athletes who want a low-calorie option.
Caffeine
Many sports drinks contain caffeine, and some even have more than one type of stimulant. This is used for athletes to enhance their performance, and can delay fatigue when they are exercising intensely.
A sports drink is designed for people who regularly participate in intense physical activities, such as long distance running or team sports. It quickly replaces the fluid lost through sweating and provides a boost of carbohydrate, which is the most efficient fuel to exercise. It can also restore electrolytes such as sodium, chloride, calcium, magnesium and potassium, which diminish along with body fluid during heavy sweating.
Other Ingredients
Functional sports drinks are marketed as products that can improve athletic performance by replacing electrolytes, carbohydrates and water lost through sweat during competition or hard training and practice sessions. These drinks are also used to increase hydration, reduce oxidative stress, and improve recovery after an exercise.
Most sports drinks available today are isotonic. That means that they contain the same concentrations as the body’s own fluids. This is important as it allows the body retain ingested fluid and stimulates thirst. It’s also essential that the drink be absorbed quickly into the bloodstream to provide energy. This is achieved by using glucose polymers such as maltodextrin, which have a low sweetening power.
Other ingredients in sports drinks include a range of vitamins and minerals, which are added to enhance the performance and nutritional value of the drink. These include magnesium, calcium, potassium and phosphate which help with the absorption of dietary carbohydrate, B vitamins which are involved in energy metabolism and the nervous system, and amino acids which can slow fatigue and improve muscle function.
While these ingredients may be beneficial to some athletes, others may get the same results by drinking bottled waters. If your child is exercising for long periods of time in hot weather, or during a very intense training session that lasts a long time, you may want to consider giving him a sport drink to maintain the proper carbohydrate and hydration balance.
