Question

Choose the statement that is true about sports drinks. All of the choices are correct. They replenish electrolytes Their flavor encourages athletes to drink They replenish fluids

Answer 1

Sports drinks are designed to hydrate, provide energy, and replenish electrolytes lost during intense physical activities, and are particularly beneficial for athletes. They come in varieties like hypotonic, isotonic, and hypertonic, each tailored to different hydration and energy needs. Their consumption should be based on the level of physical exertion.

Step-by-step explanation:

Sports drinks are formulated to serve several important functions for athletes during exercise. They are designed to rehydrate the body, replenish fluids, supply energy through carbohydrates, and replace electrolytes like sodium and potassium that are lost through sweating. The lost electrolytes are essential for nerve impulse conduction, muscle contractions, and maintaining water balance. There are three main types of sports drinks: hypotonic, isotonic, and hypertonic, which vary in their concentration of dissolved contents such as salt, sugar, and carbohydrates.

The consumption of sports drinks can be beneficial for athletes engaged in prolonged, intense physical activities because they promote hydration and may improve performance and endurance. However, for those who engage in moderate or low-intensity exercise, the additional calories and sugars in sports drinks might not be necessary. Thus, the choice to consume sports drinks should be based on the individual's level of physical activity and specific hydration and energy needs.

Answer 2

Final answer:

Sports drinks help to rehydrate, replenish electrolytes, and encourage fluid intake with their flavor, especially during prolonged physical activity. Different types of sports drinks cater to varying needs, and the American College of Sports Medicine provides guidelines on sodium content for effective rehydration.

Step-by-step explanation:

Sports drinks are designed to rehydrate the body and replenish fluids after intense exercise and fluid depletion. They contain electrolytes such as sodium and potassium, which help restore the body's balance of these important ions, necessary for nerve impulse conduction, muscle contractions, and maintaining proper water balance. These drinks are also crafted to encourage drinking through their appealing flavors, with the aim of preventing dehydration and fatigue during physical activities.

It's important to note the different classifications of sports drinks as described: hypotonic, isotonic, and hypertonic. A hypotonic drink, with a lower concentration of dissolved content compared to the human body, has relatively low carbohydrates and a higher salt concentration. Isotonic drinks are balanced near human body levels with more carbohydrates, while hypertonic drinks are loaded with carbohydrates for extensive energy replenishment and have lower salt and sugar concentrations.

The American College of Sports Medicine recommends sports drinks should contain at least 125 milligrams of sodium per 8 ounces to aid in the replacement of sodium lost in sweat and to improve fluid uptake and hydration. Despite their benefits, sports drinks should be consumed appropriately, particularly by athletes and those engaging in long-duration or high-intensity exercise who need to replace the nutrients and fluids lost through sweating.
