Multiple Choice

Which of the following statements regarding fluid balance during and after exercise is false?

Sweating during exercise leads to a loss of both water and electrolytes.

Dehydration can impair physical performance and cognitive function.

Electrolyte drinks can help restore sodium and potassium levels after prolonged exercise.

Verified step by step guidance

Understand the role of electrolytes in the body: Electrolytes such as sodium and potassium are crucial for maintaining fluid balance, nerve function, and muscle contractions. During exercise, these electrolytes are lost through sweat.

Recognize the impact of dehydration: Dehydration can lead to decreased physical performance and cognitive function, as the body struggles to maintain homeostasis without adequate fluid and electrolyte levels.

Evaluate the effectiveness of electrolyte drinks: After prolonged exercise, electrolyte drinks can help replenish lost sodium and potassium, which are not sufficiently restored by drinking water alone.

Analyze the statement about water replenishment: Drinking water alone does not replace all lost electrolytes, especially after intense exercise where significant amounts of sodium and potassium are lost.

Identify the false statement: The statement 'Drinking water alone is sufficient to replenish all lost electrolytes after intense exercise' is false because water does not contain electrolytes, and additional sources are needed to restore electrolyte balance.
