CJVA_ Nutrition Handout-2008 Vicki Hermoso Volleyball Players - Daily Nutritional Needs Power athletes like volleyball players require the majority of daily food intake to come from carbohydrates (CHO), which help maintain stamina and replenish lost glycogen stores (i.e. stored carbohydrates in muscle) in the muscle and liver during practice, a game and/or weight training. Liver glycogen is the primary fuel for energy. When the stores are low, focus and timing begin to suffer The Training Diet – your daily nutritional plan. During the season, a training diet should be comprised of 55 percent CHO, 25 percent protein and 20 percent fat. The goal of the training diet is to provide adequate energy for recovery and tissue repair quickly and efficiently, without adding body fat Pre-Game Meal The primary purpose of the pre-game meal is offset fatigue during the game. There is no one-size-fits-all prescription for the pre-game meal. Different people react differently to the same foods. Some trial and error may be needed. Athletes should try to find food that won’t cause GI distress and will help to maintain focus and endurance. A few guidelines: • • • • • • • Eat low-glycemic foods, such as whole grain cereals, certain fruits, sandwiches made with whole wheat bread, etc., approximately two to three hours before a competition. The closer to your match, the smaller the meal. This will help sustain blood-sugar levels. Keep protein and fat intakes low because they slow digestion. Avoid bulky foods, like raw fruits and vegetables, dry beans, peas and popcorn, which can stimulate bowel movements. Avoid gas-forming foods such as vegetables from the cabbage family and cooked dry beans. The American College of Sports Medicine and the National Athletic Trainers Association recommend drinking 400 to 600 mL of fluid two to three hours before exercise. Pay attention to see if you have to urinate before or during the game with such an intake. Do not try new foods just before a match. Eat foods familiar with your digestive system. Some athletes prefer to use their favorite foods, which may give them a psychological edge. During the Match Although eating as directed above will allow you to top off glycogen (carbohydrate) stores coming into the event, you're not in the clear yet. You still have to contend with two potential enemies: 1) dehydration, and 2) rapid glycogen utilization and depletion. Dehydration • • • • • A player’s rate of fluid loss will depend on the environmental conditions, intensity of play, acclimatization, aerobic fitness, hydration status, age, and gender. Performance suffers with significant fluid loss. This is detrimental to performance because weight loss as small as one to two percent of body mass (one to three pounds for a 150-pound individual) can lead to impaired blood volume, stroke volume, cardiac output and oxygen consumption. Keep fluid intake high during exercise. You should focus on consuming two liters of water an hour to prevent dehydration. Water, Water, Water. Avoid sodas, beer, malt liquor, Red Bull, juice or sports drinks. Drinking cold water is the best way to stay hydrated in the heat. For every pound that is lost, drink two cups of water. This must be determined by taking weight measurements before and after competition or following the end of the day. CJVA_ Nutrition Handout-2008 Vicki Hermoso Glycogen Depletion Glycogen depletion, or decreasing muscle and liver CHO stores, varies with the intensity of the match and your aerobic fitness level. Although liquid carbohydrates can help restore lost glycogen, it is not replenished as fast as it is lost. • • For matches longer than an hour, a carbohydrate-electrolyte drink, rather than water, is recommended. Bring a water bottle containing a solution of six to seven percent carbohydrate and electrolytes, such as CytomaxTM, HeedTM, Hammer GelTM, or GU2OTM. Try to avoid common sport drinks that contain a considerable amount of table sugar, which may lead to gastrointestinal distress and poor replacement of muscle glycogen. Post-Match Meal DO NOT FORGET the post-match meal! • • • Consume carbohydrate-rich foods and beverages within 30 minutes or as soon as possible after a match. The combination of CHO and protein has the added benefit further speeding recovery and reenergize you for your next competition. It is better to consume the meal as a liquid in order to facilitate recovery faster, and follow with a variety of whole-foods between two and four hours later. Tournament Nutrition When several games are played in succession over as many days, pro-active recovery techniques will be important in maintaining performance through the end of the schedule. The tournament schedule in volleyball is difficult to incorporate nutritional strategies for recovery, flexibility and ingenuity. Not only should the athlete be committed to looking after fluid and CHO needs between matches, but the athlete must do so without a definite time-table. As soon as a game schedule is known, plan a meal routine that schedules convenient pre-event meals and recovery strategies. When several games are played in succession over as many days, pro-active recovery techniques will be important to maintaining performance through the end of the schedule. A lack of a nutritional plan can be a critical mistake. For away games, plan where you will be eating meals and try to organize the menus in advance. While on the road, take control of meals eaten on planes, buses and other travel options. Do not depend on others to have optimal nutrition choices available. Always carry some high-carbohydrate snacks or meal replacements, such as health bars, ready-to-drink shakes and fruit and yogurt for emergencies.
