In biology, the tonicity of a solution usually refers to its solute concentration relative to that of another solution on the opposite side of a cell membrane; a solution outside of a cell is called hypertonic if it has a greater concentration of solutes than the cytosol inside the cell. When a cell is immersed in a hypertonic solution, osmotic ...
Athletes that are actively training lose water and electrolytes from their bodies by sweating, and expending energy.Sports drinks are sometimes chosen to be a solution for this problem through fluid replacement, carbohydrate loading and nutrient supplementation, [4] although the same source also states that "Whether water or a sports drink is consumed is the athlete's choice."
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
The cessation of urine flow prevents the hypovolemia and hypertonicity from getting worse; the drinking of water corrects the defect. Hypo-osmolality results in very low plasma ADH levels. This results in the inhibition of water reabsorption from the kidney tubules, causing high volumes of very dilute urine to be excreted, thus getting rid of ...

The discrepamcy is made up by very high plasma levels of urea in sharks' blood. I do not know how the boney fish cope with their hyperosmolar surroundings, other than what is suggested in this article, i.e. that they "drink" large amounts of sea water to make up for the losses through their gills, and then excrete the salt.
