Introduction Good nutrition for everyone involves eating foods that provide the body with the right balance of energy, vitamins, minerals and fluid. Although good nutrition sounds like "common sense", it is not always "common practice". Food provides all athletes with the raw materials for building new muscle, providing energy for practice and competition, aiding recovery from injury, and sustaining mental focus. The right balance of nutrients requires learning some nutrition basics, understanding how it applies to athletics, and putting the knowledge into action. This booklet will guide you through the controversial realm of sports nutrition. Carbohydrates Fueling up with carbohydrates is the key to good nutrition for sports. Carbohydrates provide 4 calories per gram and are the main fuel for the muscles and the brain. Carbohydrates are stored in the body and are gradually used up during practice or competition. If you are not eating adequate carbohydrates on a daily basis, carbohydrate stores will decline resulting in a lack of energy. This is commonly called "Hitting the Wall". It is important to "charge up" your muscles to prevent running out of energy. To ensure adequate carbohydrate intake, the recommendation for football players is approximately 2-5grams of carbohydrate per pound (lb) of body weight. Step 1. Determine your Carbohydrate Needs. Weight in pounds: lbs x 2 – 5 grams = day. grams grams x 4 calories = carbohydrate per day. Sources of Carbohydrates include: Whole grain cereals and breads Potatoes Pasta Fruit and fruit juice Legumes (beans) Crackers Rice Sports drinks - grams of carbohydrate per calories of Fat Fat is fuel source for light to moderate intensity exercise, and spares carbohydrate for longer bouts of exercise. Fat is the most concentrated source of energy providing 9 calories per gram compared to 4 calories per gram found in carbohydrates and proteins. Recommended fat intake is between 20-30% of total calories or about 0.25 – 0.50 grams per pound of body weight. Step 2. Determine your Fat Needs. Weight in pounds: lbs x 0.25 – 0.50 = calories of fat per day. grams - grams x 9 calories = - Adequate fat in the diet is important for meeting increased energy needs of athletes. The amount of fat is not the only consideration; the type of fat is just as important. Saturated fats or "bad fats" are associated with an increased risk of heart disease. The goal should be to increase the intake of unsaturated fats or "good fats". Saturated fats tend to be solid at room temperature (i.e. butter, stick margarine, shortening) while unsaturated fats are more liquid at room temperature (i.e. canola oil, olive oil, corn oil, softer tub margarines). Healthy Fats: Fats called Omega 3 and Omega 6, commonly found in fish, are not only healthy but have anti-inflammatory properties. This can be important on rest days to include foods that have the Omega fatty acids to help with inflammation and promote recovery. Dietary fat sources include margarine, oil, mayonnaise, meat, fish, dairy products, nuts and seeds. Protein Protein is needed to build and maintain muscles, form blood cells, and maintain immunity. Protein will only be used to build muscle if enough carbohydrate calories are consumed during a weight resistance exercise program. Without adequate calories from carbohydrates, protein is then used as fuel. Protein provides 4 calories per gram, with requirements for athletes range from 0.5-1 gram per pound of body weight. Step 3. Determine your Protein Needs. Weight in pounds: lbs x 0.5 – 1.0 = calories of protein per day. grams - grams x 4 calories = - Consuming more protein than the body can use does not increase muscle gain. We need to increase carbohydrate and total calories to make sure that protein is being used for muscle building and not for fuel. Good sources of protein include beef, fish, chicken, turkey, nuts and dairy products. Determine your daily calorie (energy) needs. Look back on the previous pages where you determined your carbohydrate, fat, and protein needs in calories. Transfer those numbers to Step 4. Step 4. Carbohydrate Calories - Fat Calories - Protein Calories - Total - The two totals that you get by adding the totals from Steps 1-3 is your estimated calorie need for the day. The lower number should be used when your training is light or when you are out of season. The higher number should be used during multiple-day practice sessions and when off- season training is very intense. It is best to split your energy needs into 5 meals (3 meals, 2 snacks) per day to maintain good energy. NEVER skip meals. It is as important for maintaining focus and energy to eat throughout the day and not just one meal.

It is the major component of blood and transports nutrients to your working muscles. Water also lubricates joints and keeps the body from overheating by regulating body temperature. Just as running out of carbohydrates can decrease your performance, so can running low on water. Dehydration not only impairs athletic performance, but also causes physical harm. The best way to avoid the ill effects of dehydration is to prevent it by staying hydrated at all times. Guidelines for Proper Hydration Start all exercise/practice sessions hydrated. Carry your own water bottle around to remind you to stay hydrated. Drink about 17-20 fluid ounces (fl oz) 2-3 hours prior to practice or competition. Drink about 7-10 fl oz. 10-20 minutes during exercise (competition or training) if possible. Drink at least 16oz. of fluid following exercise. During hot weather it is a good idea to weigh in before and after exercise and consume at least 16-24oz. of fluid for every pound difference. Try drinking at least 8oz. at each meal and between each meal. Rememberthirst is not a reliable indicator of hydration status. Avoid caffeine and beverages containing alcohol since they can contribute to further dehydration. Sports drinks containing carbohydrate have been associated with enhanced performance and delayed fatigue. Getting carbohydrates and fluid in the 2 hour “Recovery Window” after practice, helps recovery and rehydration. Post-Practice/Training Nutrition There is a 2 hour “Recovery Window” that we need to take advantage of to promote maximum growth and recovery. Research shows that having a combination of carbohydrate and protein immediately after training can promote muscle growth. You can use a commercially made recovery shake or use chocolate milk. The combination of carbohydrate and protein helps to replenish your energy stores and the protein helps to repair and build muscle. Be sure to eat carbohydrates, protein and drink fluid after workouts. Some foods that you can try as a recovery snack are: - Chocolate milk Carnation instant breakfast with skim milk Energy bar and water Peanut butter and jelly sandwich with fruit juice Trail mix and a sports drink Diet, The Fundamentals There are three factors involved in maximizing athletic performance through training. 1. Strength and Conditioning 2. Sound Diet, Nutritional Program 3. Proper Rest Of the three factors listed, diet is the foundation for the other two. You can follow the best workout ever designed, but if you are not eating properly, your athletic gains will suffer. The food you eat is your body’s fuel. The better the food, the better the body will perform. The subject of nutrition and diet is saturated with misconceptions. To eliminate the greatest misconceptions about diet and its effect on training, there are no miracle foods or supplements that will generate fantastic training gains. The effectiveness that diet has on training is achieved by following basic sound nutrition stemming from the basic food groups. The basic food groups of meat, fruit and vegetables, grain and dairy products supply the following six nutrients that are essential to body function. 1. Carbohydrates 2. Fats 3. Protein 4. Vitamins 5. Minerals 6. Water 1. Carbohydrates: The primary source of fuel the body uses during intense activities. Carbohydrates provide energy for basic body functions, nerve transmissions, and muscular contractions. They also assist in the digestion and assimilation of food. 2. Fats: Provide the body with a sustained source of energy utilized during moderate activity. They act as carriers for fat soluble vitamins and supply the body with essential fatty acids needed for growth and healthy skin. 3. Protein: Necessary for tissue growth and development. It acts in the formation of hormones, enzymes, and antibodies. Protein can also be used as a source of energy by the body when carbohydrate stores are depleted. 4. Vitamins: Act as regulators and catalysts for body functions. They also assist in the utilization of other nutrients. 5. Mineral: Act as catalysts for body functions. Included in these functions are muscle response, nerve transmission, digestion and utilization other nutrients. 6. Water: Probably the most important of the six nutrients. Water is essential in the digestive process and aids in the transport of nutrients in the body. It functions as a dilute and medium of elimination of toxic waste as well as being a regulator of body temperature. MAKE YOURSELF EAT! Do not spend your money on junk. Take a trip to the grocery store and buy some food! Enclosed is a simple meal plan and shopping list. Use it! When you build more muscle, you will burn more fat! Some basic guidelines to keep in mind are as follows: Consume less saturated fat, sugar and alcohol. Eat the majority of your carbohydrates in the morning and at noon. Your day should go as follows: am – carbohydrates; lunch – mixed carbohydrates and protein; pm – mostly protein Example: Breakfast Bowl of high fiber cereal Skim milk Orange juice/grapefruit juice (calcium fortified) Lunch Baked Chicken breast or Turkey sandwich Vegetable and fruit 2 slices of wheat bread Baked potato/pasta 1 slice of cheese Water Water Dinner Chicken/fish/turkey or Omelet, scrambled eggs Vegetable Water Water Eat 6-7 small meals daily instead of having only 2 or 3 meals. Eating too much at one sitting will cause sharp fluctuations in your blood sugar and insulin levels. Too much insulin in the bloodstream means a higher storage of fat. Never skip breakfast. Your body will go into starvation response. This is when you have not eaten over a period of time; your body will tend to store even “good” food as fat for future need. Try not to eat after 7:00 pm. If you have to, eat fruit, protein snack, but no simple sugars/fats, such as ice cream, pizza and burgers. In general, many athletes consume a diet that is slightly higher in protein, lower in refined sugars and lower in fat. The diet may be divided into the following: RDA 12% Carbohydrates 55-60% Fat 25-30% Variation Protein 10Protein 30-35% Carbohydrates 40-50% Fat 15-20% Drink at least 8-8 ounce glasses of water daily. This is the average population requirement. Athletes have a much greater need for water. ½gallon to 1 gallon of water is a good goal. The more water you drink, the better. Be aware of the hidden calories in drinks: Soda – 12 oz Iced Tea – 12 oz Orange Juice – 8 oz 2% Milk – 12 oz 2% Chocolate Milk – 12 oz Lemonade – 12 oz Kool Aid – 12 oz 140 calories 100 calories 102 calories 170 calories 245 calories 100 calories 140 calories Beer – 12 oz 140 calories Wine – 6 oz 120 calories Margarita – 12 oz 740 calories Rum – 6 oz 395 calories Stw. Daiquiri – 12 oz 375 calories Latte – 12 oz 250 calories Hot Chocolate – 8 oz 100 calories Avoid: Drinks with caffeine/ephedrine Colas Tea Ultimate Orange Energy Drinks To lose 1 lb per week, decrease your daily caloric intake by 500 calories.

Stay away from fried foods: fried chicken, fish, shrimp, turkey, bacon, pork chops, French fries, onion rings, fried mushrooms, cheese, etc. 2. Limit your consumption of meats high in saturated fat: hamburgers, cheeseburgers, fried meats, and dark meats. 3. Intake more lean meats such as: baked chicken without skin, turkey, fish, broiled/boiled shrimp, tuna in water. 4. Think of alternative forms of protein: egg whites, red beans, black beans, baked beans, white beans, yogurt, cottage cheese, low fat/fat free cheese. 5. Eat whole grain wheat breads instead of traditional white. It has more fiber and will convert to sugar at a slower rate than white bread. This includes other starches such as brown rice instead of white rice, wheat pasta instead of white pasta. Low Glycemic Index Foods Sweet Potato Brown Rice Whole Grain Bread Whole Grain Wheat Pasta Broccoli Peas Bran Cereal High Glycemic Index Foods White Potato – Mashed Potatoes White Rice White/Honey Wheat Bread Traditional Pasta Carrots Corn Frosted Flakes 6. You don’t need to over indulge in carbohydrates at night because their purpose is to replenish energy stores. It only takes a small amount of carbohydrates to restore your needs. Any excess is stored as fat. Proteins however, can help rebuild muscle tissue that has been broken down during activity. 7. Any food in excess is stored as fat. That is your body’s way of protecting itself from starvation. Portion control is one of the most important keys to dietary success. 8. If you look good on the outside, it doesn’t mean you look good on the inside. When you think you look good and your body fat is still high, there are 2 possibilities: you store fat internally (organ fat) or you are dehydrated. 9. Never skip meals. It will always cause a more drastic spike in your insulin levels when you finally eat. Sample Meals to Maintain, Gain and Reduce Proper nutrition is essential for the athlete who seeks to attain success. Athletes need to realize the direct relationship between proper sports nutrition and SIZE, STRENGTH, ENDURANCE AND CONDITIONING. Listed below are sample meals that you can use as a guide to help you reach your specific caloric level. Meals are divided into WEIGHT MAINTENANCE, WEIGHT GAIN, and WEIGHT REDUCTION categories.

Theoretically, this means eating an additional 500 calories per day to gain 1 pound per week. Some thin people, however, have difficulty gaining weight and have to consume far more than that. To take in the extra calories, you can eat: An extra snack, such as a bedtime peanut butter sandwich with a glass of milk Larger than normal portions at meal time divided into 5-6 meals Higher calories food Many people who try to gain weight think that a high protein diet will help them bulk up. This is false. Although you may need a little extra protein to build muscle, your normal diet undoubtedly offers more than enough. The average American easily consumes 2 to 3 times the recommended amount of protein. Hence, you do not need to spend money on protein powders, pills and special supplements. Instead spend your money on wholesome, high calorie foods. When you make your food selections, keep in mind that fats are the most concentrated form of calories. One teaspoon of fat (butter, oil, margarine, and mayo) has 36 calories; whereas, the same amount of carbohydrate or protein has only 16 calories. Since most protein foods contain fat, these foods tend to high in calories. However, some fats can also be bad for your health – such as saturated fat that is in cheese, beef, chicken skin, butter, and bacon. Hence, you should try to reduce your intake of these and focus instead on the more heart healthy fats, such as corn-oil margarine, olive oil, old fashion peanut butter, and oily fish such as salmon and mackerel. The following are suggestions to help you boost your caloric intake: Juice: Apple, cranberry, cranapple, grape, pineapple, and apricot have more calories than grapefruit, orange, and tomato juice. To increase the calories in frozen OJ, add less water than the directions suggest. Fruit: Bananas, pineapple, raisins, dates, dried apricots and other dried fruits have more calories than watery fruits such as grapefruit, plums, and peaches. Milk: To boost the calorie value of milk,¼cupaddpowdered milk to one cup of regular milk. You can also add malt powder, Ovaltine, Carnation Instant Breakfast, Nestle’s Quick or other flavoring. If you mix these up by the quart full, they’ll be ready and waiting for you in the refrigerator. You can also make blender drinks, such as milk shakes, fruit smoothies and frappes. Hot Cereal: By cooking cereal with milk, instead of water, you’ll add both calories and nutritional value. Add lots of mix-ins, such as powdered milk, margarine, peanut butter, walnuts, sunflower seeds, wheat germ and dried fruit. Cold Fruit: Choose dense cereals, such as, granola, muesli, grape-nuts, and wheat-chex. Top with raisins, bananas and other fruit. Toast: Spread with generous amounts of peanut butter, margarine, and jam. Sandwiches: Select hearty, dense breads (as opposed to “fluffy types”), such as sprouted wheat, honey bran, rye and pumpernickel – the thinner sliced, the better. Generously stuff the sandwich with tuna, chicken and other sandwich fillings. Good ole peanut butter and jelly is inexpensive, healthy and a high calorie choice. Meats: Although beef, pork, and lamb tend to have more calories than chicken or fish, they also tend to have more saturated fat. Hence, you should eat them in moderation, taking care to select the leanest cut. You can boost the calories value of lean meat, chicken of fish; by sautéing those in safflower, corn or olive oil, as well as adding bread crumb toppings. Soups: Hearty lentil, split pea, minestrone and barley soups have more calories than brothy chicken and beef types – unless these are chock full of lots of veggies and meat. To make canned soup more substantial, add evaporated milk in place of water or regular milk, or add extra powdered milk. Garnish with parmesan cheese and croutons. Beans, Legumes: Lentils, split pea soup, chili with beans, limas and other dried beans are not only high in calories but also an excellent source or protein and carbohydrates. Vegetables: Peas, corn carrots, winter squash and beets have more calories than green beans, broccoli, summer squash, and other watery vegetables. Add generous amounts of margarine, slivered almonds, grated cheese or sauces. Salads: What may start out being low calorie lettuce can quickly be converted into a substantial meal by adding cottage cheese, garbanzo beans, sunflower seeds, assorted vegetables, chopped walnuts, raisins, tuna fish, lean meat, croutons, and a liberal amount of dressing (preferably olive oil based). Potato: Add generous amounts of butter and extra powdered milk to mashed potatoes. Use sour cream and gravy sparingly. Although they add significant amounts of calories, they also add heart-unhealthy saturated fat. Desserts: By selecting the desserts with nutritional value, you can enjoy a treat as well as nourish your body. Try oatmeal-raisin cookies, Fig Newton’s, rice pudding, chocolate pudding, stewed fruit compote, pumpkin pie, carrot cake. Even blueberry muffins, corn bread with honey, banana-nut bread and other sweet breads can double as a dessert. Snacks: A substantial afternoon and/or evening snack is an excellent way to boost your caloric intake. If you don’t feel hungry, just think of the food as a weight gain medicine that you have to take. Some healthy snack choices include fruit yogurt, cheese and crackers, peanuts, sunflower seeds, almonds, granola, pretzels, English muffins, bagels, bran muffins, pizza, peanut butter crackers, milk shakes, instant breakfast drinks, hot cocoa, bananas, dried fruit and sandwiches.
