Complete Information on Better replacing fluids-water or sports drinks


Depending on how muscular you are, 55-70% of your body weight is water. Being “hydrated” means maintaining your body’s fluid level. When you sweat, you lose water which must be replaced if you want to perform your best. You need to drink fluids before, during and after all workouts and events.

Whether you drink water or a sports drink is a matter of choice. However, if your workout or event lasts for more than 90 minutes, you may benefit from the carbohydrates provided by sports drinks. A sports drink that contains 15- 18 grams of carbohydrate in every 8 ounces of fluid should be used. Drinks with higher carbohydrate content will delay the absorption of water and may cause dehydration, cramps, nausea or diarrhea. There are a variety of sports drinks on the market. Be sure to experiment with sports drinks during practice instead of trying them for the first time the day of an event.



Electrolytes are nutrients that affect fluid balance in the body and are necessary for our nerves and muscles to function. Sodium and potassium are the two electrolytes most often added to sports drinks. Generally, electrolyte replacement is not needed during short bursts of exercise since sweat is approximately 99% water and less than 1% electrolytes. Water, in combination with a well-balanced diet, will restore normal fluid and electrolyte levels in the body. However, replacing electrolytes may be beneficial during continuous activity of longer than 2 hours, especially in a hot environment.

Energy needed by muscles during exercise

Most activities use a combination of fat and carbohydrate as energy sources. How hard and how long you work out, your level of fitness and your diet will affect the type of fuel your body uses. For short-term high-intensity activities like sprinting, athletes rely mostly on carbohydrate for energy. During low-intensity exercises like walking, the body uses more fat for energy.



Carbohydrates are sugar and starches found in foods like breads, cereals, fruits, vegetables, pasta, milk, honey, syrups and table sugar. Carbohydrates are the preferred source of energy for your body. Regardless of origin, your body breaks down carbohydrates into glucose that your blood carries to cells to be used for energy. Carbohydrates provide 4 calories per gram, while fat provides 9 calories per gram. Your body cannot differentiate between glucose that comes from starches or sugars. Glucose from either source provides energy for working muscles.

Athletes should eat a lot of carbohydrates

When you are training or competing, your muscles need energy to perform. One source of energy for working muscles is glycogen which is made from carbohydrates and stored in your muscles. Every time you work out, you use some of your glycogen. If you don’t consume enough carbohydrates, your glycogen stores become depleted, which can result in fatigue. Both sugars and starches are effective in replenishing glycogen stores.

When and what to eat before completion


Performance depends largely on the foods consumed during the days and weeks leading up to an event. If you regularly eat a varied, carbohydrate-rich diet you are in good standing and probably have ample glycogen stores to fuel activity. The purpose of the precompetition meal is to prevent hunger and to provide the water and additional energy the athlete will need during competition. Most athletes eat 2 to 4 hours before their event. However, some athletes perform their best if they eat a small amount 30 minutes before competing, while others eat nothing for 6 hours beforehand.

For many athletes, carbohydrate-rich foods serve as the basis of the meal. However, there is no magic pre-event diet. Simply choose foods and beverages that you enjoy and that don’t bother your stomach. Experiment during the weeks before an event to see which foods work best for you.

Bating sugary foods

In the past, athletes were warned that eating sugary foods before exercise could hurt performance by causing a drop in blood glucose levels. Recent studies, however, have shown that consuming sugar up to 30 minutes before an event does not diminish performance. In fact, evidence suggests that a sugar-containing precompetition beverage or snack may improve performance during endurance workouts and events.
