a) What has happened to his blood pressure, blood osmolarity, cell size and vascular compartment volume?

b) What type of fluid imbalance does Usain Bolt have?

Answer 1

a)Usain Bolt might have

1.lower blood pressure due to low intake of fluid combined with heavy sweating resulting into lower blood volume thus low blood pressure.

2.Hyperosmolar blood condition, decrease in total body water relative to electrolyte content .

3. Extreme shrinkage of cell size.

4.Vascular compartment volume decreases due to contraction of vascular muscle and resulting into increased flow of lymph,high protein content from the vascular compartment.

b)Hypernatremia type of fluid imbalance Usain bolt will have due to increase in serum sodium concentration compare to total body water content.
