e load ™ Endurance Formula Sport Drink Snapshot
The most important physiological job of your sport drink is to maintain your fluid and electrolyte balance.
In hot conditions this can be especially challenging. A great sport drink helps in the prevention and control of heat stress, primarily by replacing sweat electrolytes and fluid as they are lost. If electrolyte balance is maintained within, and you supply enough fluid to replace losses (see our Nutrition Calculators) you are well on your way to success in the heat!
You Should Know
- .... that syptoms of heat stress include muscle cramps, stomach upset, stomach cramps, nausea, flatulence, diarrhea, headaches, dizzyness, unusual fatigue and delirium. Sometimes, a coma, and even death, can be blamed on extreme heat stress, as can a very important condition known as hyponatremia.
- .... that the most important ingredients in a sports drink responsible for the prevention of heat illness are adequate amounts of electrolytes. Virtually all sports drinks have a maximum of 1/6 - 1/2 of the concentration of electrolytes that you lose in your sweat. (8) Depletion of these valuable electrolytes are a big reason why heat stress leads to heat illness, including the ever common muscle cramps. The Anti-Cramp formula in e load™ has been helping cramping athletes everywhere.
- .... that Dextrose, the principal carbohydrate in e load™, is a high glycemic carbohydrate that is rapidly absorbed and yields instant energy. Additionally, dextrose is the carbohydrate of choice for a sports drink made to combat heat stress. The biggest reason for this is that dextrose actually facilitates sodium absorption from the small intestine, unlike other carbohydrates (1,2,3,4). This is why many oral medical rehydration solutions contain dextrose as the principal carbohydrate (5). Also, the presence of dextrose and sucrose together may enhance each other's absorption (enhanced 'solute flux'), and maybe more important than the osmolality of the carbohydrates themselves (37).
- .... that for optimal performance in the heat, replacing sodium and potassium (the two most abundant electrolytes in sweat) in the ratio in which they are lost from sweat means less chance of succumbing to heat stress. This ratio averages between 3:1 and 5:1 i.e. your drink should contain 3-5 times more sodium than potassium. Most sports drinks completely ignore this important physiological truth.
- .... that acid buildup from prolonged high level physical exertion acts like "muscle glue", and its' accumulation may be more pronounced in the heat. Acid causes muscle burning and heaviness, inhibiting normal muscle contraction, resulting in reduced performance. It makes sense to have an ingredient in your sports drink to counter these problems.Check out our acid killing MultiCitrate™(9).
- .... that everyone of you is different, with different sweat tendencies, and different levels of electrolyte in your sweat. In fact, there is a 50-100% variation in the levels of sweat electrolyte from person to person. We at Medion are well aware of the differences that exist in the physiology of individuals, and for those needing it, we enable you to ingest even more electrolyte with our innovative ZONE CAPS X 5 TM Buffered Electrolyte Capsules.
- .... that excess stomach acid is a problem for many people in stressful situations, causing stomach pain, cramps, nausea and vomiting. Exercise can be stressful, especially high intensity exercise in the heat, and the extra stomach acid secreted in these situations can contribute to gastrointestinal distress. e load™ addresses this issue with its' low acidity formula. In fact, compared to a drink like Gatorade, e loadtrade; has 35 times LESS acidity.
- .... that Calcium loss through sweat may actually predispose athletes to bone loss and stress fractures when inadequately replaced. An average loss of calcium per litre of sweat is 50 milligrams (which happens to be the amount found in e load ™) (38).
