FUELING TO PERFORM
Christa Petersen, RD | Registered Dietitian | [email protected] | 732-602-8677
Fo r Yo u r Te e n A t h l e t e
1. To understand the three major forms of fuel for the student athlete (and fluids)
2. To describe the connection between when to fuel to optimize performance before-during and after an event
3. To provide the coaches with t ips to counsel their student athlete(s)
4. To answer any questions
Objectives
Athletes energy requirements depend on:
The Beginnings
• Fr e q u e n c y • I n t e n s i t y• Fa t - Fr e e M a s s We i g h t
• G e n d e r• Te m p e r a t u r e
• Stress
Girls Teens ages 13-19…
• Experience advanced maturation because increased muscle mass favors power and performance
Experience increases in
the proportion of body fat to muscle mass
Both girls and boys will accrue
15% of final adult height and 45% of maximum
skeletal muscle
Boys
• Experience increases in lean body mass and
increased blood volume
•C a r b o h y d r a t e s : Should be the foundation of student meals•P r o t e i n : An accompaniment for each meal• Fa t : A little (healthy) fat at each meal• Healthy Fat includes: Avocados, Olive Oil, Nuts
• F l u i d s : You want to replace sweat losses to keep your body hydrated
Building a Sports DietT h e B a s i c s t o
• There are two families of C a r b o h y d r a t e s• Complex – Whole wheat flour, Fruits with peels, Oatmeal, Fiber• Simple - Honey, White Flour, Sports Drinks, sugar
• Carbohydrates are the primary fuel source for the muscles
Carbs 101M a c r o n u t r i e n t # 1 :
G l y c o g e n (the storage form of Carbohydrates) is found in
the muscles and liver to prevent an athlete from “hitting
the wall”
At l eas t 50% o f to ta l da i l y energy shou ld come f rom carbohydrates fo r young
a th le tes
Carbs 101M a c r o n u t r i e n t # 1 :
Potatoes
Fruit Bread Legumes
Cereal
• P r o t e i n is responsible for:• Maintaining • Repairing• Synthesizing
• Protein is especially essential for teen athletes to help with growth and muscular development
Protein 101M a c r o n u t r i e n t # 2 :
Lean proteins that are recommended include: eggs, nut butters, low-fat
dairy, legumes, lean chicken, beef, fish and tofu
Protein 101M a c r o n u t r i e n t # 2 :
Lean Beef Lingo:

• Extra calories (from carbohydrates)• Strength training• Adequate protein• For example: 180 pound (82kg) teen football player needs
about 1.5-2.0 g per kg weight • 82kg x 1.5g = 120g-164g/day
• Frequent eating throughout the day• Timing

Do you think…
YES! Believe it or not athletes who ate a lower carbohydrate diet (50% of energy coming from carbs) had decreased muscle endurance after 7
days on the diet, while athletes who ate a higher carbohydrate diet (70% of energy
coming from carbs) decreased rates of fatigue

M e a l A :
1 baked potato4 ounces sirloin steak (1/4 of plate)¾ cup steamed green beans
M e a l B :
8 ounces chicken (1/2 of the plate)1 cup steamed green beans
Remember: building muscle also relies a lot on resistance exercise rather then just protein consumption alone
•Fa t i s n e e d e d :• To cushion the internal organs• Provide extra energy stores• To provide cell membrane structure
•Healthy Fats• Omega-3 promising for athletes with exercise-induced
asthma. Not effective to reduce inflammation, enhance immune system, or improve performance • Limit high fat and fried foods

Acceptable Macronutrient Distribution Range (AMDR) suggests that 20-35% of
daily energy intake should come from fat.

Eating Before Exercise…
Subjects ate dinner and the next day biked hard-Tr i a l A : No breakfast = reduced performance
Tr i a l B : With Breakfast (400 cals)136 minutes till exhaustion (27 minutes
longer)
• G e n e r a l N u t r i t i o n • Any activity lasting longer than 1 hour and is limited by
carbohydrate stores• Athletes should arrive at activity well fueled and with full
glycogen (stored glucose) stores to maintain activity level.• Consume carbohydrate-rich and easily digestible foods and
drinks prior to practice or competition.
Endurance Sports
• Repeated bouts of high-intensity or maximal exercise, lasting from a few seconds to 3 minutes. • Sprinting, jumping, power lifting, wrestling, rowing.
• These sports are anaerobic (without oxygen) in nature and energy comes from the b r e a k d o w n o f g l y c o g e n s t o r e s • Energy/calorie intake needs to be adequate

• Protein is needed for the development of muscle that is needed for power and strength sports• If c a r b o h y d r a t e i s l o w t h e b o d y w i l l u s e p r o t e i n s t o r e s for energy
St r en gth , We igh t C l ass , an d Speed Spor t s…
• High intensity, intermittent efforts that are repeated over the duration of a game of 30-90 minutes. • Require a combination of power, agility, coordination, speed, and
endurance. • Adequate macronutrient intake is needed to prevent energy depletion.• Fluids are needed to prevent dehydration during these events
Adequate nutrit ion before, during, and after activity wil l promote recovery and maintenance
of lean body mass.
Team Sports
• If participating in multiple games/matches throughout the day, athletes should replenish in between with:• Lower fat, moderate protein, carbohydrate-rich meals • Fluids containing carbohydrates and electrolytes

Tournament Feeding
Supplements and Ergogenic A ids are safe for a l l
ath letes…everyone uses them !
Myth or Fact?
•Dietary supplements use and ergogenic aids are not recommended for young athletes and is actually banned by the AAP•Many substances are banned by the sport governing body, so not worth the risk• Can get desired results from healthy balanced diet and positive adaptations from training
MYTH

A s a s t u d e n t a t h l e t e c o a c h :• Encourage students to consume breakfast• Give examples such as a bagel breakfast sandwich, oatmeal
with nuts, peanut butter, banana sandwich,
Recommendations
• Encourage student athletes to gain their nutrition from foods first
If your student athlete isn’t performing like their usual, ask them what they ate for the day• Did they have breakfast?• What did they eat for lunch? • When was the last time they are?
I f you question the qual ity and timing of their meals• Tell them to track their food consumption and time of when they eat • Ask them how they felt after eating
Recommendations
Consider having team challenges:Students have to work together to achieve their nutrition goals
For example: Challenge every student athlete to eat breakfast and set up the challenge to include certain categories daily:
Recommendations
Grain and/or Fruit Dairy ProteinMashed Banana, Strawberry and 2 whole grain pieces of Toast
1% Milk Peanut Butter
Please free to contact me as I can come and speak to your student athletes about proper
fueling before-during-and-after their specific sport whether for practices or on
competition day
