Isotonic Drink

During exercise, your body sweats to help regulate body temperature. This loss of fluid can be extremely detrimental to performance and therefore athletes must compensate by drinking to replace lost fluids. Not only that, but when we sweat we lose key electrolytes such as potassium and magnesium which are essential for performance. They must also be replaced to encourage moisture retention and stimulate thirst.

In addition to this, performance in prolonged exercise is reliant on the availability of muscle glycogen and therefore it can be important to take on carbohydrates during exercise to replenish fuel stores. If no carbohydrates were consumed during prolonged or intense efforts, muscle glycogen stores would be depleted afterapprox. 90min. The amount of carbohydrate you should take during exercise depends on the length of the session or event.

• Exercises < 1h:not necessary to consume carbohydrates during exercise .
• Exercises 1-2h:30-60g carbohydrates per hour exercise.(~500-1000 ml Isotonic)
• Exercises 2-3h:60-90g carbohydrates per hour exercise.(~1-1,5 L Isotonic)
• Exercises > 3h: 90-120g carbohydrates per hour exercise. (~Up to 1.5 L Isotonic)

The Etixx Isotonic contains both maltodextrin and fructose. Research has shown that consuming multiple sources of carbohydrate can increase the absorption of fuel into the body as they use different transporters to cross the intestinal wall (1).

Therefore, during exercise, this would provide your body with more fuel in a shorter time compared to the ingestion of one sugar alone.

In the Etixx Isotonic formula, there is a 2:1 ratio of maltodextrin to fructose. This has the advantage that:

• more consumed carbohydrates are oxidized
• the stomach will empty faster
• fluid absorption is higher
• there is a lower risk of gastrointestinal complaints.

Who will benefit from drinking the Etixx Isotonic?

The isotonic thirst quencher is a drink that is suitable for all athletes who need to quickly restore fluid balance and replenish energy and electrolytes. It can be of benefit to all athletes, from explosive sports such as sprinters, to team sports, to endurance athletes. It is also the ideal sports drink for training and competing in hot weather.
