North Americans are chronically dehydrated, but the problem is most acute in active individuals and athletes. The body needs 500 ml of liquid for each 500 gm of weight lost through activity, but athletes typically consume only half that. Even slight dehydration can compromise heart function and have a negative impact on cognitive function. As little as 1 percent dehydration (600 to 800 ml of water loss) can impair physical function, while 2 percent can reduce exercise capacity, and more than 7 percent can cause collapse.
Water loss also means loss of nutrients, including electrolytes, vitamins, and minerals, which can affect athletic performance and overall health. Most sports drinks restore water, sugar and salt but not nutrients. Ideally, a sports beverage should contain electrolytes, carbohydrates, minerals, and vitamins that can help athletes exercise longer and harder, and recover more quickly.
How it Helps
Electrolytes Important electrolytes include potassium, sodium, chloride, and magnesium. Sweating, exercise duration/intensity and temperature can increase electrolyte loss. Electrolyte loss due to exercise lasting more than four hours can impair heat tolerance, reduce performance, and induce cramps, exhaustion, and heat stroke. Moreover, complete re-hydration cannot occur without electrolyte replacement.
Our bodies convert carbohydrates to glycogen, which is stored until it is needed to fuel energy. Strenuous exercise significantly depletes glycogen and can result in fatigue and injury. Complete replenishment of glycogen generally takes 24 to 48 hours, but this can be lessened by consuming carbohydrates immediately after an intense workout, preferably in liquid form, which can be absorbed quickly.
Vitamins C and E
Strenuous physical activity depletes antioxidants, increasing oxidative stress. Hydrade® contains the antioxidant Vitamins C and E. The Vitamin C in Hydrade® is Ester-C®, which is highly bioavailable and easy to digest.
Exercise depletes B vitamins, which perform many functions, such as supporting carbohydrate, protein, and fat metabolism. As well, 100 mg of thiamine daily may alleviate or prevent exercise-induced fatigue. Hydrade® contains thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), cyanocobalamin (B12), and folic acid. Trace Minerals Trace minerals help convert carbohydrate, fat, and protein into energy. Chromium supports balanced blood glucose, which helps control weight and energy. North Americans tend to be deficient in chromium; this is especially true of athletes.
Other Important Points about SISU Hydrade™
• Sports drinks are most beneficial when consumed throughout exercise to help maintain blood glucose levels. This becomes more important when exertion continues for more than one hour.
• The rules of some athletic events and the nature of some activities limit fluid consumption. In such cases, consume 500 ml of Hydrade™ one to two hours before the event and again immediately afterward to prevent dehydration.
• As Hydrade™ is a concentrated source of vitamins and minerals, it should be sipped slowly over 30 to 60 minutes.
