Answer :
Final answer:
The best choice for an aerobic endurance event lasting about an hour would be a drink at 55 degrees F with a 6% carbohydrate concentration. Such hypotonic drinks are more easily absorbed and utilized by the body than isotonic or hypertonic ones. Temperature-wise, cooler beverages can be absorbed quicker and help keep athletes cool during long exercise periods. The correct option is A.
Explanation:
For an athlete participating in an aerobic endurance event that lasts approximately one hour, the most appropriate beverage would be A. 55 degrees F; 6% carb concentration. Sports drinks are designed to aid with hydration during exercise, replenishing not only water but also essential minerals lost through sweat, including sodium and potassium. Additionally, sports drinks provide necessary carbohydrates, vital for maintaining energy levels over an extended period of aerobic activity.
There are three main types of sports drinks: hypotonic, isotonic, and hypertonic, which differ in terms of the concentration levels of sugar, salt, and carbohydrates relative to the human body. Specifically, isotonic drinks, which have a carbohydrate concentration that closely mirrors that of the human body, may be an effective choice for events of shorter duration. However, for events over an hour, a hypotonic drink like option A may be more appropriate due to its lower carbohydrate concentration, which can be more easily absorbed and utilized by the body.
Finally, temperature plays a role in drink selection for athletes. While personal preference might come into play, colder drinks are, in general, absorbed faster by the body and can assist with cooling the athlete during prolonged activity. So a drink at 55 degrees F (like option A) might offer some additional benefits.
