Measurement of dissolved particles in a biological fluid.
Total concentration of dissolved solute particles (electrolytes and non-electrolytes) per liter of solution, expressed in osmoles per liter (mOsm/L).
Osmolarity determines the tendency of a solution to attract water through a semi-permeable membrane.
Determines the movement of water between body compartments and regulates cellular hydration.
Consume isotonic or slightly hypotonic drinks during exercise to maintain osmotic balance.
Osmolarity is the primary driver of water movement and cellular hydration.
