Fitness & Nutrition: Getting Proper Nutrition When in Season

Printer-friendly versionSend to friend

Tennis is an intense physical sport that burns a lot of calories. During the tennis season, it is very important to follow nutritional guidelines that will help an athlete to perform at their highest potential. Tennis is not a timed sport, therefore nobody can predict when a match will be over. An athlete must be prepared all the time before, during and after the match. The best way to prepare is to hydrate and load up prior to your match, eat small snacks that are high in electrolytes at changeovers, and reload within an hour after completion.

When in season, food planning and the timing of meals are key to success on the court. By properly maintaining energy, an athlete will not only keep their blood sugar steady and avoid the ups and downs of energy on the court, but also prevent many injuries.

No diets during the season please! Don't avoid carbs, skip meals or snacks, or avoid electrolyte fluids! Specialty diets must be strictly supervised by a doctor or nutritionist.

Athletes benefit the most from the amount of carbohydrates stored in the body. In the early stages of moderate exercise, carbohydrates provide 40 to 50 percent of energy requirements. Carbohydrates yield more energy per unit of oxygen consumed than fats. During digestion, the body breaks down carbohydrates to glucose and stores it in the muscles as glycogen. During exercise, the glycogen is converted back to glucose and is used for energy.

The ability to sustain prolonged vigorous exercise is directly related to initial levels of muscle glycogen. The body stores a limited amount of carbohydrates in the muscles and liver. If the event lasts for more than 90 minutes, you will run out of your energy source and will "hit the wall.”

Players that play both doubles and singles must eat double the amount of carbohydrates and lean protein (even more for men) in order to sustain energy.
