Sports Nutrition for the High School Athlete
Physically active individuals have special nutritional needs. Learning what and when you should eat and drink may improve your performance. Eating right can help you feel good and stay fit throughout your lifetime.
For older athletes that have entered puberty (for example: boys ages 13-18), muscle growth is accelerated with the onset of puberty brought about by the presence of testosterone. It is at this phase of a young athlete’s development that strength training can be introduced, in addition to proper diet, and rest. Strength training, proper diet, and rest will encourage the growth of lean muscle mass. High school football weight training, in particular, can be beneficial in supporting the player’s strength and weight goals. With diet and intentional strength training, weight gain of up to 15% per year is not uncommon in this phase of an athlete’s life. Below are two growth chart assuming 15% annual weight growth and approximately 1 inch of height growth per year and 10% weight growth per year. Note that these weight growth and height growth assumptions may not be achieved every year.

It's important to know which kind of activity your partaking in because each kind of activity as its own set of dietary rules.
Activity Definitions:
- Endurance — Vigorous, continuous activity for an hour or longer. Examples are distance running, cycling and cross-country skiing.
- High Intensity — Short bursts of maximum or near maximum effort. Examples include weight lifting and sprinting.
- Moderate — Physical exertion difficult enough to increase your heart rate and cause heavy breathing, but easy enough to sustain for more than 30 minutes. Examples include aerobics, playing basketball and brisk walking.
- Low Intensity — Everyday activities that involve movement of major muscle groups. Examples are walking up stairs, walking to the store and washing the car.
How Activities Affect Calorie and Protein Needs:
The best diet for all athletes consists of 55 percent to 65 percent of total calories from carbohydrate, 25 percent to 30 percent from fat and 10 percent to 20 percent from protein.
- Endurance — The energy demands of endurance activities are high. It is important that the body has adequate fuel stores for activities of long duration. For elite athletes, such as marathon runners or triathletes, energy needs are often as high as 3,000 to 5,000 calories per day. These athletes also have increased protein needs. Once the body's carbohydrate stores are depleted, muscle protein is broken down for energy. If you regularly perform endurance activities, your calorie and protein needs are at the upper end of the recommended range.
- High Intensity — High-intensity sports affect nutritional needs in different ways based on the activity and the person's body size. These athletes have increased calorie needs, though not as high as endurance athletes. Weightlifters do need more dietary protein than the average person. In fact, protein intake in excess of the recommended levels does not increase muscle mass or strength and can lead to dehydration, osteoporosis and kidney disease.
If you are performing high-intensity activities on a regular basis, your calorie needs are at the middle of the recommended range and your protein needs are at the upper end of the recommended range.
- Moderate Intensity — Moderate-intensity sports increase your caloric needs depending on the frequency and duration of your activity. In general, be sure you are consuming adequate calories by eating at least the lower end of the recommended range. Consistently under-eating will eventually lead to fatigue and hinder your athletic performance.
- Low Intensity — Low-intensity activities do not alter calorie and protein needs. These activities are important to include on a daily basis for general health benefits.
Energy and Protein Ranges for Active Individuals:
To calculate your calorie needs:
1. Divide your body weight in pounds by 2.2 to get your weight in kilograms.
2. Multiply your weight in kilograms by 40.
3. Add 100 calories for every 10 minutes of activity you do on an average day.
To calculate your protein needs:
Multiply your weight in kilograms by 2 to get the total grams of protein you need each day.
Example:For a young man who weighs 185 pounds and works out an average of 90 minutes a day, five days per week:
- 185 / 2.2 = 84.1 kilograms body weight
- 84.1 x 40 = 3364 calories per day
- 3364 + (9 x 100) = 4264 calories per day
- Protein needs: 84.1 kilograms x 2 gram of protein = 168.2 grams of protein per day
Tips for gaining lean muscle mass:
- Lift weights and condition with a sense of urgency – do not just go through the motions, do your best – lift hard, run hard, work hard. Attend every workout – don’t skip workouts. Learn to get comfortable being uncomfortable during workouts – push yourself to do your best
- Never skip meals. Yes, this means you need to get up in time for breakfast, you can’t skip lunch, and dinner actually needs to be prepared and eaten.
- Eat at least five times per day – Three meals and two snacks
- Drink caloric beverages. Choose milk or 100% fruit juice when available.
- Choose calorie-dense foods. That means eating potatoes, corn or peas instead of celery and carrot sticks. Or choosing a banana or cranberry juice instead of an apple or orange juice. Granola cereal is more calorie-dense than puffed rice.
- Eat more when you can. Take seconds and thirds when possible if you are trying to gain weight.
- Eat protein throughout the day. Players should not count more than 30 grams of protein in one sitting of whole food. For example a huge steak that has 100 grams of protein cannot be counted as 100 grams toward their total number for the day; only 30 of it may be counted. Players should never go more than 2- 3 hours without having some source of protein.
- Protein shakes are OK. If drinking a 100 gram protein shake only 50 grams can be counted during one sitting because its predigested protein that can be utilized immediately. But a player may not eat the food and shake in the one sitting and count it all...it’s one or the other.
- Eat as many carbs as you want. Players can eat as many carbs as they wish in one sitting because carbs are much easier to digest and can be stored, whereas whole food protein cannot be stored and is more difficult to digest.

Parents often ask what can be done to give their player the best chance to secure a D1 football scholarship. In fact, less than 1% of all high school football players are offered a scholarship to play football at a Division 1 program. (The percentage of players that play at Division 2 and Division 3 programs is somewhat better but still relatively small). That said, college coaches are generally looking for players that are relatively big, fast, athletic, and have the ability to graduate from college. Regarding optimal size and weight by position, there are some height and weight guidelines that some colleges use (see below). However, there are always exceptions to these guidelines. Nearly every collegiate team has productive players that may not meet the height and/or weight guidelines. Accordingly, the table below should be used as a general guideline only.

Water Needs and Activity:
During physical activity, water has many important functions. It serves to cool the body, maintain adequate blood flow to working muscles and allow for the body's basic functions to continue to work. Relying on sense of thirst will not keep you properly hydrated because the body's thirst mechanism is dulled during exercise. By the time you feel thirsty, you are already in a state of mild dehydration.
Use the following tips as a starting point for remaining adequately hydrated. Then monitor weight changes and the color of your urine to determine your own fluid needs following activity. When you are properly hydrated, your urine will be clear or very pale in color. When your body is dehydrated, your urine will be a darker shade.
The best replenishment drink is water. Sports beverages can be used, though they can be high in sugar and calories. These drinks are only beneficial if you have performed an endurance activity for more than 60 minutes or if you are exercising in an especially hot or humid climate.
Summary
For older players, strength training with intent and discipline, proper diet, and rest are necessary to achieve full potential. Lifting and conditioning with discipline, eating well (and eating often throughout the day – target 5 times per day), and getting the necessary rest will provide the best chances for the athlete to reach his full potential and will increase his chances of playing at the next level.

- Before Exercise — Drink 20 to 40 fluid ounces (or 3 to 5 cups) of water over the two to three hours before activity and another 4 to 8 ounces every 15 to 20 minutes prior to starting exercise.
- During Exercise — Consume 4 fluid ounces (1/2 cup) of water for every 20 to 30 minutes of activity.
- After Exercise — Immediately after exercise, drink 16 fluid ounces (2 cups) of water for every pound of weight lost. This requires that you weigh yourself before and after exercise. Since this may not be practical in some situations, weigh yourself before and after an activity, when you have access to a scale and use this as a basic guide.
The best replenishment drink is water. Sports beverages can be used, though they can be high in sugar and calories. These drinks are only beneficial if you have performed an endurance activity for more than 60 minutes or if you are exercising in an especially hot or humid climate.
