Answer:

cause cells to shrink due to an increase in the osmolarity of extracellular fluid.

Explanation:

Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.

A hyperosmotic solution can be defined as a solution having an increased level of osmotic pressure. Thus, when there's a greater amount of solute with respect to another solution in a membrane with close similarities, it is known as hyperosmotic solution.

Basically, hyperosmotic solution gives rise to higher difference between solutes and similar solutions.

Hence, when a normovolemic person consumes a large quantity of a hyperosmotic solution, it will cause cells to shrink due to an increase in the osmolarity of extracellular fluid i.e the total number of solute particles with respect to the concentration of a solution (Osm/L).

This finding strongly recommends that middle-aged people should undertake some form of regular exercise so as to not fall into the category of "sedentary".
