Question

24 multiple choice 2 points
which statement regarding fluid and electrolyte replacement for athletes is correct?
athletes such as marathon runners should take salt tablets and drink concentrated electrolyte solutions.
water is the best rehydration fluid and electrolytes can be replaced by eating fruits and a small amount of salty foods.
athletes have greater needs because they sweat more and lose more fluids and electrolytes
concentrated glucose solutions are best for rehydration.

Explanation:

• Option 1: Taking salt tablets and concentrated electrolyte solutions is not recommended as it can cause issues; the body absorbs dilute solutions better.
• Option 2: While water is good, for athletes with significant sweating, sports drinks or balanced electrolyte sources are often better than just fruits/salty foods for optimal electrolyte replacement.
• Option 3: Athletes sweat more during physical activity, leading to greater loss of fluids (like water) and electrolytes (like sodium, potassium), so their needs for replacement are higher. This is correct.
• Option 4: Concentrated glucose solutions are not ideal for rehydration as they can slow down fluid absorption due to osmotic effects.

Answer:

C. Athletes have greater needs because they sweat more and lose more fluids and electrolytes
