Osmolality and Fueling for Sport: Why it Matters
- 15 Jan 2024
Osmolality is a measure of the number of dissolved particles in a solution. You can think of it as a fancy word for the concentration, or density, of a fluid. Scientifically speaking, the osmolality of a solution refers to the concentration of osmotically active particles in that solution. Osmolality is a function of the number of particles and is not related to particle weight, size, shape, or charge. Almost every fluid has an osmolality above zero — Except for distilled water, which has been processed to remove all other substances or “solutes” from the water molecules.
