2Performance Nutrition Means
- Eating or Fueling to boost performance training
or competition, on a daily basis - Fueling to decrease the risk of injuries, recover
fully after workouts and stay healthy - Teaching athletes to fuel with foods that taste
good, foods they enjoy, foods - that can be prepared easily,
- and foods they feel confident
- eating

4Consequences of Poor Nutrition
- Weight loss
- Strength loss

5Nutritional Concerns for Athletes
- Are they eating enough?
- Eating frequently, Skipping meals, Meal Timing
- What are they eating?
- Nutritious calories vs. Junk Calories
- Are they hydrating properly?
- Are they feeding their muscle during exercise?
- Do they understand Nutrient Timing Principles?
- Are they taking too many supplements?
- Do they know what theyre taking?
- Looking for the quick fix without a basic food
plan
6Energy Needs
- Calories/ 120
160 240 - LOW - sedentary 1560- 1800
2080-2400 3120-3600 - ACTVE (30-60min) 1920-2160
2560-1880 3840-4320 - MODERATE (1-1.5hr) 2280-2520 3040-3360
4560-5040 - HIGH (1.5-2hr) 2640-2880
3520-3840 5280-5760 - VERY HIGH (2-3hr) 3000-3600
4000-4800 6000-7200
7Calculating Your Energy Needs
- My Recommendations for YOU!
- Calories bodyweight x 14-18
- Protein- .6 to 1g/lb. bodyweight, max
- Example
- 150 lb
- 2,400 calories
- 90-150 grams of protein
- 225 lb
- 3600 calories
- 135 225 grams of protein
8Case Study
- Its the week before Janes regional gymnastics
meet and she feels like she should cut down on
her calories since she is training less. After
eating this way about a week, she is feeling
irritable and tired. Her legs are sore and it
takes a long time to get warmed up when she goes
to practice. Recent labs indicate a low ferritin
level. The coach asks the sports dietitian to
make a few suggestions to get her back on track
before the big meet. You need to convince Jane
that cutting out more calories is not the best
way to train even when the workouts are starting
to taper off. Food is fuel and shes running on
empty. - For better performance, Janes calories and
carbohydrate grams should be based on current
body weight for the initial calculation. Her
weight is 130 lbs (or 59 kg). She is 54 and
she is 16 years old. - Basic calorie needs (12.2 x weight in Kg)
749 -gt (12.2 x 59) 749 1470 calories for
minimal metabolism - Multiply this number by activity factor 1470 x
(1.6 1.8) 2350 - 2646 calories - Carbohydrate grams BW in Kg x 5 to 8 (use a
factor or 7 10 during periods of heavier
training) 295 - 472 - Protein Grams BW in kg x 1.2 1.6 since she is
in a taper season 71 -94 -

13Sample Athlete

-
- 675 gm CHO
- That means little to nothing to most athletes
14How Much is 675gm of CHO?

15Protein Is Essential
- Protein is used to build, repair and maintain
tissue. It promotes normal growth and development
in a young athlete. - A male athlete can utilize approximately 14-30
grams every 3-4 hours. - A female athlete can
- utilize 7-21 grams in
- the same time period.
16Individuals with Higher Protein Needs
- New training program
- Energy Restriction
- Diet or extreme expenditure
- Vegetarians
- Disease
- Injury rehab
- Young or old athletes
These arent the people typically using
protein supplements!
17Case Study
- Andre is a defensive tackle training for the
combine and the 2008 NFL draft. His playing
weight in college was about 280 - 285. His agent
wants him to be 295 or more by his Pro Day in
March. The first day he checks in with you after
his bowl game in January, he weighs 274. He will
be living in an apartment and the facility where
he trains provides him breakfast and lunch as
well as supplements. Use a weight of 285 to
calculate values. -

20Physiological Effects of Dehydration
- sweat rate blood volume
heart rate -
- core body heat
-
- cardiovascular function
- -less O2 and nutrient-rich blood to
muscles - -more reliance on anaerobic system
- Slower removal of wastes cramping,
fatigue
21Recommended Fluid Intakes
- Timing Amount
- 2 hours before 2 cups
- 10-15 minutes before 1 - 2 cups
- Every 15-20 minutes during ½ - 1 cup
- After Activity 2 - 3 cups for every
pound lost
22What About Energy Drinks?
- Rock Star, Full Throttle, Red Bull, Cocaine,
Bawls - Significant increase in athletes using it as a
food substitute, especially girls. - May provide a quick boost of energy,
- followed by a rapid drop in blood sugar.
- Will increase core temperature.
- May increase rate of dehydration
- or risk of heat illness.
23Nutrient Timing is Important-Will You Crash and
Burn?
24Pre-Exercise Fuel
- This is a loading phase
- Provides energy to working muscles
- Maximizes blood sugar and glycogen stores
- Provides a psychological edge
- Minimizes hunger during play
- Maximizes hydration
- Must be individualized
25Pre-Practice Snack Ideas
- SNACKS TO THROW IN YOUR BACKPACK OR GYM BAG OR
VENDING MACHINES - It's not easy to find
nutritious quick food here, but some choices are
wiser choices than others - grab these when you
are in a hurry. - Bagel Dried Fruit Fresh Fruit
- Trail Mix Fig Bars
Low-fat Cookies - Rice cakes Granola Bar Graham
Crackers - 100 Juices Raisin Bread
Cheese Sticks - Cheese Crackers Nuts
Pretzels - Chocolate Milk Dried Fruits
Muffins - Dry Cereal Peanut Butter Crackers
- Sports Bars Shakes
26Refueling after Exercise
- VERY Important for Athletes
- For those in multiple events in one day
- For those training daily
- Window for Refueling
- First 30 minutes after exercise is critical
- Glycogen repletion occurs faster after exercise
- Increased blood flow to the muscle
- Enzymes that produce glycogen are most active
27Post-Exercise Examples
- Energy Bar/Granola Bar/Cereal Bar and Sports
Drink - Bagel and Sports Drink
- Turkey Sub Sandwich and Sports Drink
- Burrito and Sports Drink
- Pasta with Chicken and Sports Drink
- Waffles/Pancakes/French Toast and Low fat Milk
- Cereal and Milk
28Recovery Drinks
- 41 carbohydrate protein ratio
- What is that?
- This ratio represents a food that has 4 grams of
carbohydrate for every 1 gram of protein - Why is that important? 2 main reasons
- Body NEEDS lots of carbohydrate post-exercise to
replace energy stores carbohydrates come first! - Carbohydrates help protein enter the muscle
cell they unlock the cell to allow nutrients
in - Body needs some protein to start repairing tiny
muscle tears
29Recovery Drinks
- Ratio of 41 Recovery Drink Examples
- Low-fat chocolate milk
- Accelerade, PowerAde Recovery
- 8 oz low-fat milk 1 small banana blended
- 3 scoops Muscle Milk Collegiate in 12 oz water
- 2 scoops Muscle Milk Collegiate in 12 oz 1 milk
- 32 oz Gatorade ½ scoop whey protein powder
- Shake (4 oz 1 milk, 8 oz orange juice,1 banana,
¾ scoop whey protein powder )
30What About Supplementation?
- To supplement the body with nutrients it may not
receive in sufficient amounts from food (ex.
Multivitamin) - To regenerate disrupted/damaged muscle tissue
after exercise training - To ensure sufficient calorie intake
- To enhance recovery or refill your gas tank
- The day-to-day process (ex. Tour De
France or repeated 2-a days at football)
31Whats The Problem with Supplement Use?
- Dangers of athletes purchasing supplements
- Dont understand ingredient list
- Most supplements have multiple ingredients
(especially Weight loss pills) - Side effects caused by supplement
- Appropriate dosage for safe supplements
- More is better
- Exact reason why they are taking them
- Sold by someone who has less knowledge than they
do (supplement store employee, gym employee, or
even a coach)
