Nutrition and Sport Drinks


Summer is almost here and with the advent of the traditional kick-off to the season,Memorial Day week-end almost here, I thought it may be a good time to talk about the importance of re hydration. Americans spend a lot of time outdoors participating in various activities. From the little leaguer to the major pro-athlete, and all construction workers in between, summer brings a heightened awareness of the need to replenish fluids and salts, lost during physical exertion.

The most high profile of the sport drinks, Gatorade brand, is consumed at every major league sporting event and has become a staple for sports enthusiasts everywhere. The main functions of the sport drink according to a study conducted at Vanderbilt University are to encourage the following:
1. rapid fluid absorption
2.rapid re hydration
3.transmission of energy to working muscles
4.drinking more fluids


This is achieved, by using a mixture of water, sugar(carbohydrates) salt(electrolytes) and a variety of flavorings. This precisely measured mixture is designed to help us avoid problems related to extreme physical exertion from working and playing hard like, the loss of fluids and salts, overheating, and depleting energy.


The following is from a Gatorade brand label:

serving size: 8fl oz; calories 50; total fat 0g; sodium 110mg; potassium 20mg; total carb 14g; sugars 14g; protein 0g;

The ingredient labels vary according to flavor, but the main ingredients are sodium, sucrose, glucose fructose and water. For long distance running,biking and other activities that require an extended period of physical endurance, the sport drinks were shown to provided a better benefit than plain water, due to being fortified,plus having great taste and potability.In addition, these popular drinks were not shown to cause any gastro-intestinal problems.


Make sure to have plenty of fluids for your next outing, including fresh water and your favorite sport drink. If you're on a budget like most, you may want to try the following mixture. You will need to measure your ingredients precisely.*Do not use a salt substitute without first consulting your physician. Do not serve to children under the age of twelve.You will need:


1 quart water
1/2 teaspoon baking soda
1/2 teaspoon table salt or *salt substitute
3-4 tablespoons sugar
