What adverse response is known to occur in people who drink copious amounts of water while participating in intense physical activity?

a. elevated blood sodium

b. dehydration

c. metabolic alkalosis

d. ketoacidosis

e. hyponatremia?

The correct answer is hyponatremia. This is also called water intoxication in athletes. Water is a substance that is devoid of any solutes and electrolytes. The major extracellular electrolyte sodium is present in the extracellular fluid and the plasma. In the event of increased water intake, the sodium in the plasma will be diluted hence will cause hyponatremia.
