Running, swimming and cycling all come under the ‘endurance’ banner: performing strenuous exercise for long periods of time. These activities require carbs for energy and plenty of fluid to avoid dehydration. isotonic drinks can help power exceptional performances by providing hydration – crucial when sweating over a long period of time, and an additional source of energy right when you need it.

For an exceptional performance, water alone is not enough. Your body is 60% water so, for results to be proud of, your body fluid must be kept at its optimum level. When you exercise, you sweat which increases the risk of suffering from the negative effects of dehydration such as headaches, fatigue and cramp. Today, isotonic drinks are the preferred choice for most fitness enthusiasts and athletes wanting exceptional hydration and energy. Isotonic drinks have a similar carbohydrate and electrolyte concentration to your body meaning they are absorbed as fast, if not faster, than water.

An osmolality level of 270-330 Mosm/kg in an isotonic drink helps to maintain the required concentration of electrolytes in your blood. Water alone has a very low osmolality level and it typically does not contain electrolytes. Although it is great for hydration, water also stimulates urine output which reduces its effectiveness during your exercise or any sporting performance. More information on isotonic sports drinks
