What is osmolality and why is it so important?
The osmolality of a drink is the measure of the number of particles in a solution. In an isotonic drink these particles will comprise of carbohydrates and electolytes (salts). An osmolality level of 270 – 330 Mosm/kg in a sports drink helps to maintain the required concentration of electrolytes in your blood. Our bodies consist of 60% water so, for results to be proud of it must be kept hydrated. When exercising, the high loss of fluid through sweat increases the risk of suffering from the negative effects of dehydration such as headaches, fatigue and cramp. Water alone has a very low osmolality level as it typically does not contain electrolytes. Although it is great for hydration, water also stimulates urine output which reduces its effectiveness during exercise or any sporting performance.
