The Principles of Isostar
ISOSTAR sports drinks (in the refreshing flavours lemon and orange) are the best evidence for the fact that the researchers at ISOSTAR are prepared to make a special commitment to the needs of high-performance athletes. They have carefully studied all the physiological processes that take place while a competitive athlete is training, and in the course of this reached the following conclusions:

First

An adequate intake of fluid is absolutely essential.

Second

Ensure you get an adequate supply of energy.
When you set about your sports activity, you will rapidly exhaust your reserves of glycogen. This is because your body stores the carbohydrates in the form of glycogen, which is then available as the first energy reserve at times of stress, yet which also has to serve as fuel for your brain and heart during training and competition. When under stress, the digestive system can only perform its tasks to a limited extent, which means that the body needs fresh supplies of energy in a form that it can absorb and utilise easily. Otherwise even a highly concentrated energy supplement will have no effect, or might even detract from your performance.

ISOSTAR sports drinks are formulated in such a way that – provided the powder is dissolved in the correct quantity of water – they have precisely the right concentration of carbohydrates and electrolytes. It would be a mistake to believe that you can get a more potent mixture or a better energy boost by using less water. The ISOSTAR sports drinks are composed in such a way that they give the athlete significantly greater benefits before, during and after the training or competition than ordinary (hypotonic) water or the (hypertonic) 12-percent sugar solutions of cola-type soft drinks.

Carbo-loading refers to the increased inclusion of complex carbohydrates in the dietary plan over an extended period of time prior to a competition, and in parallel with a decrease in individual exercise components as part of the training programme (tapering). However, you should not use ISOSTAR sports drinks for such long-term carbo-loading because these outstanding sports drinks were simply not developed for that purpose.

Overly high sugar concentrations in the fluids you drink – that means everything with more than 8% sugar (cola-type soft drinks contain 12% monosaccharides) – slow down the transit through the stomach. This, as a result, feels unpleasantly full and in turn slows down the intestinal passage, that is to say the speed with which the fluid flows through the intestine where it is resorbed.

The consumption of drinks with higher sugar concentrations (over 12%) has even more harmful effects. First, these high sugar concentrations generally extract fluid from blood and muscles towards the digestive tract and thus rob the muscles of water. And this takes place at just the moment when the muscles need the water most. Second, they cause the blood-sugar level to soar. In other words: these drinks effect a much greater insulin output to the blood stream than would normally be the case. And this insulin orders the fatty tissue of your body to absorb the sugar. But it could get even worse and re-sult in a rebound phenomenon, that is to say a collapse of the blood-sugar level that deprives your body of the urgently needed fuel and results in a feeling of weakness and confusion.

Third

You need electrolytes.
Even though you may be extremely fit and take great pains to ensure that you tackle every training session and every competition with an adequate reserve of body fluid, you will sweat more than a less well-trained athlete. The better adjusted your fluid balance and the higher your fitness level, the greater the perspiration potential of your body will be. In this way, your body can easily get rid of the heat generated through sports activities.
As a consequence, you will lose sodium (salt) and chlorine – two very important electrolytes – due to sweating. These have to be replaced, ideally through an isotonic solution containing salt, because this in turn will motivate you to drink more. ISOSTAR sports drinks have been specially developed to cover this need.
With a carbohydrate concentration of 6.9% (5.1% of which is sugar) ISOSTAR gives you a rapid energy boost by means of a measure of highly digestible, safe and effective carbohydrate. With its carefully calculated share of sodium and potassium, ISOSTAR stimulates your thirst and simultaneously contributes to the replacement of electrolytes lost by sweating. In addition, sodium together with carbohydrates acts to ensure that the sodium pump at the intestinal wall gets going. Atthe same time as the sodium and glucose are transported into the cell, water is also carried along. In this way, the body obtains urgently needed fluid in an efficient manner. With two delicious flavours – lemon & orange– ISOSTAR perfectly reflects the taste of athletes who tend to develop a preference for sweet things when under physical stress.
With a carefully tested mixture of sugar and maltodextrin, ISOSTAR gives you the carbohydrates you need in a form that enables you to replenish the glycogen reserves in the muscles, without provoking an excessive insulin surge. ISOSTAR sports drinks are non-sparkling and supply you with fluid, carbohydrates and the essential electrolytes in a manner that precisely follows the recommendations of the world’s leading experts in the field of sports nutrition.
