Stats on Teen Athletes
•Current estimates indicate that 55.5% of high
school students compete in sports1
•Texas has the greatest number of high school
athletes1
•Most coaches and athletes have inadequate
knowledge of sport specific nutrition2
•Parents want more positive messages about
nutrition from health care professionals that are
specific to youth3

Hydration
•Never underestimate the value of hydration
•Differences in thermoregulation exist between
children and adult athletes
•Teen athletes are particularly poor at hydration
‐Thirst is not a good indicator of dehydration in sports
•AAP policy statement for children & adolescents8
‐Adolescents may consume up to 1-1.5 liters of fluids
every hour of exercise
‐Who is at highest risk?
Page 11
Pediatrics

Food Is Fuel
•High school athletes tend to
‐Skip breakfast
‐Eat at least one meal at school
‐Come to practice 4+ hours after eating
•Consequences of under-fueling5
‐Loss of lean body mass
‐Earlier fatigue/suboptimal performance
‐Increase risk for injury & illness
‐Prolonged recovery & healing
‐Menstrual dysfunction

Optimal Training Diet
•Abundant in Fluids
Water, milk, 100% juice,
sports drinks
‐Drink all day
•Ample in nutrient dense
carbohydrates
Whole grains
breads/pasta/cereals, fruits,
vegetables, low fat milk/yogurt,
beans , energy bars
‐50-70% of total calories
•Adequate in protein
Lean meats and fish, low
fat dairy, nuts, beans
‐15-20% of total calories
Dairy products, nuts, heart
healthy oils and butters ,
avocado
•Balance of fat
‐20-35% of total calories
Page 19
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:04 AM
Carbs are King!
•Main source of energy for
working muscles & academic
brain
•Inadequate carbohydrate
consumption can lead to
glycogen depletion
•Younger athletes have smaller
gylcogen stores and more
limited glycolytic capacity than
adults12

Page 20
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:04 AM
Carbohydrates
•Low intensity, skill based athletes with large body mass
or energy restriction
‐3-5g/kg/d
•Moderate Exercise Program ~1 hour per day
‐5-7g/kg/d
•Endurance Program 1-3 hour moderate to high intensity
‐7-10g/kg/d
•Extreme Commitment >4-5h per day moderate to high
intensity
‐8-12g/kg/d
Page 21
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:05 AM
Pre-workout Fuel
•Ideally 3-4 hours before
event/practice, maybe again 1
hour before
•High in carbohydrate, low or
moderate in protein, low in fat,
low in fiber
•High individual tolerance
•Race day NOT a good time to
try a new food!

During Exercise
•Prepubertal athletes may rely more on exogenous
carbohydrate intake during exercise than post12
•30 grams (120 calories) of carbohydrate per hour
during 1 to 2 hours of exercise
•60-90 gram (240-360 calories) of carbohydrate per
hour for exercise lasting more than 2.5 hours
•Easily absorbed carbohydrates
‐Sports drinks, banana, gummy candy, gels, dried fruit
‐Swish and spit?
Page 23
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:06 AM
Protein5
•Post Pubertal Non exercising:
‐0.8 gm/kg/day
•Maintenance/Endurance athletes
‐1.2-1.4 gm/kg/day
•Strength/resistance athletes
‐1.4-1.8 gm/kg/day
•Teens
© Liddy Hansdottir - Fotolia.com
‐1.4-1.5 gm/kg/day (can be higher if actively growing)
•Most teens exceed this intake12
Page 24
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:06 AM
Fat12
•Few studies have investigated fat intake for active
teens
•Recommendations are the same as general for age
‐20-35% daily calories
•Younger athletes rely more on fat as fuel than adults
•Especially important for endurance athletes
•Restriction of fat intake in non-obese children may
result in impaired growth and development
Page 25
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:07 AM
Post-workout Fuel: Recovery5
•Muscles replenish energy stores most efficiently
within 30 minutes after exercise
•Type of carbohydrate
‐Fructose alone less affective that glucose and sucrose
•Addition of protein promotes maximal repair and
anabolism
‐Carbohydrate to protein ratio of 3:1 or 4:1
•Goal: 1.5 grams of carbohydrate per kg with 0.30.5 grams/protein/kg per 2 hour interval
Page 26
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:08 AM
Key Nutrients of Interest5
•Calcium & Vitamin D
•Iron, Zinc, Magnesium
•B Vitamins
•Vitamin C, E, Beta carotene, selenium
•Sodium, chloride, potassium
•Omega 3 Fatty Acids
Use of a multivitamin supplement does not improve performance
in athletes consuming nutritionally adequate diets
Page 27
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:08 AM
Vegetarian Athletes5
•Variety & monitoring body weight/body composition
is important to ensuring adequacy of diet
•Protein recs increase to 1.3-1.8gm/kg/day
•Protein quality may be of concern if athlete is a
vegan
•May be at risk for low intakes of energy, fat, vitamin
B12, riboflavin, vitamin D, calcium, iron, zinc
•Females may be at greater risk for developing iron
deficiency anemia

Disordered Eating in Teen Athletes15
•Increased incidence at the onset of adulthood (1825 years) supports prevention strategies in
adolescence
•Female athletes and those with >16 hours/week of
activity have an increased tendency toward
disordered eating
•“Anorexia Athletica”
•“Lean-build sports”
‐cross country & track runners, swimming, gymnastics,
cheerleading, yoga, wrestling, dancing
•Can result in suboptimal bone mass in adulthood
Page 30
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:10 AM
Alcohol and Teens21
•Drinking alcohol after exercise negates training
effect, hinders recovery, increases likelihood for
injury, decreases immunity
•Alcohol can increase appetite and promote weight
gain
•Males athletes are more likely than females to
drink heavily
•Team sports in adolescence increases likelihood of
alcohol intoxication

Grocery Store Tips for Athletes
•Perimeter of store = good
•Middle aisles = not as good
•Fruits & veggies = fluids & vitamins
•Round or Loin = leaner cuts
•Olive & canola oil = heart healthy
•100% whole wheat = Magnesium
•Blue/red/purple foods = helps delay muscle soreness
Page 45
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:20 AM
To Gain Lean Body Mass
•Weight (muscle) gain is as hard to do for some as
weight loss
•Needs more than just protein but also, strength
training stimulus and extra calories
•Increasing calorie intake 300-500 calories per day
equates to ½-1 pound of body weight per week
•Late-maturing adolescents usually most concerned
about gaining muscle and size
Page 46
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:21 AM
To Gain Lean Body Mass
•Always eat breakfast
•Eat every 3-4 hours
•Pack high calorie snacks
•Add fluids that contain calories to meals
•Increase portion sizes
Page 47
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:21 AM
To Lose Body Fat
•A combination of proper training, calorie deficit,
plenty of protein, & enough, but not too many,
carbohydrates
•Cutting back on about 300-500 calories equates to
½ -1 pound of body weight per week
•Body composition assessment techniques
•Lowest reference body fat for adolescents16
‐7% males, 14% females – adolescents
Page 48
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:22 AM
To Lose Body Fat
•Don’t skip or restrict meals
•Fill up on fruits and vegetables
© Geoffrey Whiteway – freerangestock.com
•Avoid foods with added fats and sugars
•Decrease carbohydrates in meals that are not
before workouts
•Increase aerobic exercise as needed

Page 51
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:23 AM
Athletes & Supplements
•An athlete is fully responsible for all prohibited
substances found in his/her body
•Athletes generally don’t ask their doctors for advice
on taking supplements - you need to ask them!
•Scientifically testing products is becoming more
common, but the industry is still highly unregulated
Page 52
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:24 AM
Teen Athletes and Supplements12,17
•Supplements for adolescents are generally not
recommended
‐Very few studies in children and adolescents
•Nonetheless, supplements are very popular among
adolescents
‐Most commonly used are sports drinks, multivitamins, vitamin
C, iron, whey protein, caffeine, & creatine
•Younger elite athletes tend to be more
performance focused and less health conscious
than adults with regards to supplements

Whey Protein Powders
•Helps in conjunction with CHO
•Increases muscle mass more aggressively than
other proteins
•Enhances immune function
•Effective for those who don’t eat enough
•Isolate vs concentrate
•No more or less effective than food!
Page 55
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:26 AM
Creatine
•Amino acid that provides energy to muscles,
usually as phosphocreatine
•Delays fatigue during explosive exercise
•May benefit those who are naturally deficient
•Dose:
‐20 gm total/day (divided) for five days, followed by 3-5 gm
per day to maintain.
•Sources: red meat, poultry, fish
•Water retention
Page 56
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:27 AM
Creatine Guidelines for Teen Athletes18
•Only recommended when the athlete is a serious competitor
and is post-puberty.
•The athlete is eating a well-balanced sports diet that
optimizes performance.
•Both athlete and parents understand the effects of creatine
supplementation and approve of taking the supplement. No
one can guarantee safety.
•Qualified professionals supervise the supplementation of
only reputable brands of creatine supplements.
•The athlete does not take more than the recommended
dose.
Page 57
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:28 AM
Caffeine
•Both a CNS and muscular stimulant
•Increases alertness and decreases perception of fatigue
•May increase fat utilization & decrease CHO
•Sources: Energy drinks, coffee, tea
•Optimal Dose: 3-6mg/kg taken ~1 hr prior
•Doping threshold in urine
•Symptoms of caffeinism
•Adolescents may be more sensitive to effects

Branched Chain Amino Acids
•Leucine, isoleucine, valine – essential amino acids
known to fuel skeletal muscle
•Assists in synthesis of other amino acids
•Helps muscles absorb BG for energy
•Slows water absorption
•Food Sources: Dairy, eggs, red meat, fish,
legumes
•Dose: 1-5gm/day
Page 60
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:30 AM
Beet Root Juice19
•Modulation of nitric acid
•Reduces oxygen demand
•Optimal for events lasting
5-30 minutes
•Poor taste
•Dose: 300-500mg
•Food sources:
‐beets, Chinese cabbage, leeks,
spinach, arugula, endive, fennel,
parsley, celery, kohlrabi

Sodium Bicarbonate
•Base that buffers lactic acid in the blood
•Delays onset of intracellular acidosis
•Enhances anaerobic exercise performance
•Ideal for 400-800 meter runs
•Dose: 0.3+gm/kg 1-2 hrs prior
•Diarrhea side effect
Page 62
Pediatrics
xxx00.#####.ppt 9/10/2013 11:51:32 AM
Beta-Alanine20
•An amino acid building block for carnosine, a
compound naturally found in muscle
‐Leads to a gradual increase in muscle carnosine. which
buffers muscle acids produced during high-intensity physical
activity
‐Reduces muscle burn and fatigue
•Dose: 3-6 g/day
•Relatively new, promising, but only a few well
designed studies have shown beneficial as well as
no improvements

Summary
•Nutrition can play an essential role in the health
and performance of competitive adolescent
athletes
•Adolescent athletes require more fluid, calories,
carbohydrates, proteins, and many key vitamins
than their non-athletic peers
•Meal time constraints, poor nutrition knowledge,
and pubertal body changes are among the many
barriers to optimal sports nutrition for adolescents

Summary
•Timing and composition of meals before, during, and
after exercise are crucial for optimal sports
performance and recovery
•Adolescent athletes at highest risk for suboptimal
nutrition are those who under-fuel, are vegetarian, have
disordered eating, or abuse alcohol
•Although supplements are popular and commonly used
among adolescents, they are not generally
recommended
•Individual assessment by a CSSD is recommended to
best meet an elite athlete’s nutritional needs
