what are isotonic sport drinks

Q. What are the benefits of an isotonic drink in comparison to hypotonic or hypertonic sports drinks?
A. A key difference between these types of drinks is the osmolality level which is the level at which a fluid
is absorbed. An osmolality level of 270-330 Mosm/kg in an isotonic drink helps to maintain the required
concentration of electrolytes (salts) in your blood. Water alone has a very low osmolality level as it typically
does not contain electrolytes. Isotonic sports drinks replace fluids and electrolytes whilst providing energy from
carbohydrates - ideal for endurance sports, cardiovascular workouts and team sports. Hypotonic sports drinks
quickly replace fluids lost from sweating but have a low level of carbohydrates which some athletes such as
gymnasts may prefer. Hypertonic sports drinks are very high in carbohydrates and are normally taken after
exercise to top up muscle glycogen stores e.g. after ultra distance running events.

Q. I drink water throughout my gym sessions, isn’t water enough? Why should I use an isotonic drink – I’m not an athlete?!
A. Isotonic drinks contain carbohydrates to help you to stay energised whilst also helping to keep you hydrated by replacing fluid and precious electrolytes (salts) which are lost through sweat; helping you to avoid the negative effects of dehydration during and after exercise. Even moderate intensity exercise will create sweat resulting in a loss of electrolytes and energy. An isotonic drink has a similar carbohydrate and electrolyte concentration to your body, meaning that your body will absorb them faster than water alone.

Q. Which types of sports drinks are in the market, which are the key differences and key benefits?
Types of Sports Drinks

Key Differences

Key Benefits
Isotonic Fluid, high level electrolytes and 6 to 8% carbohydrate. Rapid hydration and energy.
Hypotonic Fluid, low level of electrolytes and very low level of carbohydrate . Quick hydration but lower levels of carbs so no immediate boost of energy.
Hypertonic Fluid, very high level of carbohydrate, typically low level of electrolytes or none. A way to supplement daily carbohydrate intake to help top-up muscle glycogen stores. Not typically as effective at re-hydrating the body, as the fluid is not easily absorbed.

Q: What is osmolarity and why is it so important?
A: The osmolarity of a drink is a measure of the number of particles in a solution. In an isotonic drink these particles will comprise of carbohydrates and electrolytes (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.

Q: What are mixed tocopherals?
A: Mixed tocopherols consist of a variety of natural components, collectively known as vitamin E, obtained from edible vegetable oils that possess antioxidant properties. Antioxidants are known to help protect the body against the potentially damaging effects of free radicals.
