Continuum of Adaptations Pure Strength/Power
Increased muscle mass "Neural factors Technique
Mixed
Requires a combination of the adaptations for pure strength/power and endurance depending on the specifics.
Pure Endurance
Mitochondria Cardiac adaptations Enzymes of energy production Blood volume Technique Efficiency
Training stimulates adaptations, nutrition supports them.

Continuum of Training Pure Strength/Power Mixed Pure Endurance
Strength/Power Technique Tactics Work Capacity Little 'endurance'
Requires some combination of both the pure strength/power and pure endurance depending on the specific event.
High Volume Endurance Quality work (intervals, etc.) Efficiency Technique Tactics Strength/power training usually limited

General Nutritional Tendencies Pure Strength/Power Mixed Pure Endurance
Energy
Protein
Carbs
Fat
-
Energy Intake Part 1 Energy Intake Part 2 Use body composition changes as a determinant
Non-deliberate weight loss: eating too little Body fat going up: eating too much Variations in caloric intake generally from changes in daily
carbohydrate intake
Female specific issues Female athletes notorious for undereating Not losing weight but can't train or compete optimally
B O D Y R E C O M P O S I T I O N
Roles of Dietary Protein Structural "Muscle Hair Skin Bone Connective tissues
Neurotransmitters Tryptophane Serotonin Tyrosine-> Dopamine, Adrenaline, Noradrenaline
Other Immune System Gut Function Anti-bacterial Blood pressure Analgesic effect
Hormones Growth Hormone IGF-1 Catecholamines Thyroid (tyrosine) Albumin
Energetic Glucose production Ketone production Alanine, leucine burned in muscle
Can vary significantly between athletes and sports 40-50 cal/kg (18-22 cal/lb) at 90 minutes per day of training Can be much higher given modern training volumes and loads
Also varies with a given training day- Day off: 30-33 cal/kg (-15-16 cal/lb) Medium training day (1 hour): 35-40 cal/kg Heavy training day (90'+): 40-50 cal/kg or more
Sample Athletes 60kg female: 1800-3000 cal/day 100kg male: 3000-5000 cal/day
R E C O M P O S I T I O N
Protein: Introduction Many roles in the body: structural, hormones, energy, etc.
(next slide) Only source of nitrogen in the diet Provides Amino Acids
- 8 Essential (MUST come from the diet) - 12 Non-essential (CAN be made in the body) - Conditionally essential/etc.

l u i i i u w u m i w u i i w i i w i v w i i i i i i m m Daily Protein Recommendations:
Amount Type of Sport Male Female
Mixed 2.5-3.0 g/kg 2.4-2.6 g/kg
Sample daily protein recommendations: 60 kg female athlete: 144-156 g/day 100 kg male athlete: 250-300 g/day Note: Protein should be set by lean body mass.
B O D Y R E C O M P O S I T I O N
Daily Protein Recommendations: Type
Some protein found in most foods Animal: red meat, chicken, fish, dairy Vegetable: beans, nuts Other: Fruits, vegetables, grains
No Single Best Protein Source (refer to handout)
Mix and match from different high quality sources
Protein from non-animal sources (e.g. grains, breads, etc.) counts towards daily total as part of a mixed diet
B O D Y RE C O M P O S I T I O N
Daily Protein Recommendations: Timing
Ideally get protein with each meal
Divide up daily total throughout the days meals
On training days, some part of the days totals will come around training
Dietary Fats: Introduction Primarily an energetic role
Stored body fat (long-term fuel storage)
Intramuscular triglycerides (IMTG) Can affect physiology in other ways
- Inflammation Immune system function Cell membrane fluidity Etc.
-
Daily Fat Recommendations: Amount
Type of Sport Male Female
Mixed 1.1-2.2 g/kg 1.1-2.2 g/kg
Sample daily fat recommendations: 60 kg female athlete: 66-132 grams 100 kg male athlete: 110-220 grams
B O D Y S ^ R E C O M P O S I T I O N
Daily Fat Recommendations: Timing
Ideally get fat with each meal
Divide up daily total throughout the days meals
Generally avoided around training (especially pre/during) but acceptable post-workout
Dietary Fat Recommendations: Type
Trans-fatty acids: processed foods, should be minimized
Saturated fat - Primarily found in foods of animal origin - Medium Chain Triglycerides (coconut oil, palm kernel oil)
Monounsaturated fat: vegetable oils, olive oil Polyunsaturated fat
- Two essential fatty acids: alpha-linoleic acid, linolenic acid - Vegetable oils - Fish oils: MUST be consumed daily.
B O D Y R E C O M P O S I T I O N
Dietary Carbohydrate: Introduction Primarily an energetic role
Muscle and liver glycogen
Blood glucose maintenance Dietary carbohydrate myths
Insulin makes you fat - Carb conversion to fat
Carbs are 'bad'
-
u i v u u u u u u u u i m u u i m i u i i i m i i Daily Carbohydrate Recommendations:
Amount type of Sport Male Female
Mixed 3.0-6.6 g/kg+ 3.0-6.6 g/kg+
Sample daily carbohydrate recommendations: 60 kg female athlete: 180-400 g/day 100 kg male athlete: 300-660 g/day
Daily Carbohydrate Recommendations: Type Part 1
Complex vs. Simple
Glycemic index (GI) and Glycemic Load
Sources: Grains Fruits Vegetables Other: Dairy
B O D Y f R E C O M P O S I T I O N
B O D Y R E C O M P O S I T I O N
Daily Carbohydrate Recommendations: Type Part 2
Fruits/vegetables must be part of the daily intake. Also helps to ensure fiber intake
Starches: usually required to meet high carbohydrate requirements of athletes High caloric requirements of athletes may necessitate some 'junk food'
Daily Carbohydrate Recommendations: Timing
Ideally get carbohydrates with each meal
Divide up daily total throughout the days meals On training days, some part of the days totals will come around training

Vitamins and Minerals Nuts and bolts: support endless biological processes
Specific examples - Iron: critical for blood status - Zinc: hormone levels - Calcium: bone health, body composition - B12: Pernicious anemia
Generally only improve performance when correcting a deficiency
Females more likely to be deficient in Iron, B12, Zinc
B O D Y iff R E C O M P O S I T I O N
Basic Meal Planning
Most eat the same stuff over and over
Once you get calorie counts for standard meals, you don't have to track quite so much
Eating out is achievable: most places have calorie counts
Module 3: Meal Planning
B O D Y R E C O M P O S I T I O N
Learn to Eyeball The benefit of measuring for at least a little while
Use standard estimates - Deck of cards ~= 120 grams meat (-25 grams protein)
Small fist ~= 100 grams carbs (25 grams carbs) Tennis ball -=200 grams fruit (25 grams carbs) Dietary fat: Vz ping pong ball ~= 14 grams (14 grams fat)

u v u u u u u u u u u Modular Eating
Pick protein source first: often contains some fat or carbs
Pick carb source next: often contains some carbs or fat
Use fat to balance out the meal (e.g. add olive oil to salad)
While a little boring, makes adjusting food intake much easier esp. carbohydrate intake.

Module 4: Around Workout and Competition Nutrition
B O D Y f ) D E C O M P O S I T I O N
Four Phases of Around Workout Nutrition

6am 7am 8am 9am 10am 11am 12pm 1pm 2pm 3pm 4pm 5pm 6pm 7pm 8pm 9pm
Key Phase 1:1-4 hours before training Phase II: 0-30 minutes before training (including warmup) Phase III: During workout Phase IV: Immediately after training to 1-2 hours afterwards
Each phase has distinct but overlapping effects.
-
Goals
Timing
Pre-Workout Nutrition Part 1
Top off liver/muscle glycogen Part of daily ongoing nutri t ion
1-4 hours before training Not skipped with few exceptions
Weight class issues Fasted endurance training Technical workouts Athletes training first thing in the morning
B O D Y R E C O M P O S I T I O N
Pre-Workout Nutrition Part 2
Size of meal Size of athlete Type of workout (volume/intensity) How long between meal and training
Content Mixed meal (protein, carbs, fat, fiber) How long until training? Variability between athletes
B O D Y R E C O M P O S I T I O N
Immediate Pre-Workout Nutrition Part 1
Goals
Timing
Appropriate blood glucose levels (central drive) Hydration Pre workout protein/amino acids: may improve adaptation
30 minutes to start of training Rebound blood sugar issues Warming up inhibits insulin response
Pre-Workout Nutrition Part 2
Liquids generally > solids Also helps with hydration
Carbs: faster acting (dextrose, glucose, maltodextrin)
Proteins
Rapidly digesting (whey/soy)
Fat and fiber: should be avoided
Creatine: for strength/power workouts B O D Y R E C O M P O S I T I O N

Goals
Timing
)ur ing Workout Nutrition Part 1
Improve performance during workout or competition Decrease fatigue/enhance recovery during/after training
Overlaps with immediate pre-workout nutri t ion Blood glucose rebound issue redux Distributed vs. all at once Nutrients in fluid sipped through training 11/hour maximum fluid intake
B O D Y f R E C O M P O S I T I O N
Post-Workout Nutrition Part 1
Goals - Glycogen resynthesis
Rehydration Initiate/improve adaptations to training Enhance recovery to prepare for next workout
Timing Immediately following training to 1-2 hours afterwards Timing issues
Immediate vs. delayed When is next workout
Eventually shifts to normal daily nutrition
-
u m i i m m m M T T i ) During Workout Nutrition: Part 2
Fluid - 1 1/hour maximum, some may need less than this
Taste important (Sodium/Potassium) What about gels/solids?
Carbohydrate intake Numerous effects (performance, hormonal, immune system) All carbs more or less equivalent 30-60 g/hour (72 g/hour with multiple sugars)
Protein - Decrease protein breakdown/muscle damage
Improves recovery - Fast protein (whey/soy)
10-15 g/hour max. Other: Avoid fat and fiber B O D Y f R E C O M P O S I T I O N
Post-Workout Nutrition: Part 2 Size: Enormous Variability
Nature of training Goals of athlete (hypertrophy, fat loss, performance)
Glycogen resynthesis Benefits (performance, training capacity, gene expression) Strength/power vs. endurance training Time between bouts (24 hours vs. 4-6 hours) Carbs vs. carbs + protein
Carbs + protein for the win - Carbs/insulin inhibit protein breakdown
Protein/amino acids stimulate protein synthesis
-
Post-Workout Nutrition: Part 3 Proteins
High-quality protein superior BCAA/leucine Fast vs. slow proteins (whey, casein, milk protein isolate)
Carbohydrates Dextrose, maltodextrin, sucrose, fructose, starch
Fat/Fiber issues
Creatine
Solid vs. liquid meals I ) /* | 1 V / I ) I J | J I ^gpF R E C O M P O S I T I O N
Post-Workout Nutrition: Part 4 Rehydration
- Water not optimal: sodium/potassium increase retention 1.5 L fluid needed for every 1kg weight loss during training
The Power of Milk Superior to water or sports drinks for rehydration Pros
Whey + casein = fast + slow protein (> soy) Inexpensive, readily available, TASTY!
Cons May require excessive amounts for large athletes
Lactose intolerance/dairy allergies Use as a base to add other nutrients (carbs/protein)
B O D Y C t R E C O M P O S I T I O N
Concerns About Around Workout Nutrition
Fat gain - Especially female/weight class athletes
Negative hormonal response All basically unwarranted
B O D Y R E C O M P O S I T I O N
Competition Nutrition Rule #1: Don't change anything the day of a competition
Test out different pre, immediate pre- food combinations during training, not on game day
Nothing fundamentally changes from around workout concepts
Dynamics of game vs. practice (e.g. chances to drink during game)
Post-workout May take precedence Let's talk about alcohol

Water and electrolyte loss during activity can vary 10 fold - Sodium loss during activity
Quick and easy method - 5 clear urinations per day, 2 after training
More accurate method - Weigh before and after training
Every 1kg weight loss requires 1.5 liter fluid to replace Do NOT gain weight during training: hyponatremia
- Currently impossible to estimate sodium losses easily
Module 5: Hydration
R E C O M P O S I T I O N
Hydration: Individuality
-
m i v n v m v m v m i n i Impact of hydration on performance
Even slight dehydration can impair performance Extreme dehydration can cause heat stroke or death Cramping issues
Hydration myths 8 glasses/day: pulled out of someone's butt Drink X ml per pound body weight
- Only water counts: nonsense Caffeinated beverages
Thirst is imprecise
Very complicated - Interaction with sodium, potassium, magnesium and
others Many find that the amino acid taurine helps
Sufficient hydration can only help but may not solve problems
Lite salt for sodium/potassium intake
What about creatine?
Stimulants/ephedrine/fat burners and cramping

Hierarchy of Nutritional Requirements
Module 6: Supplements
B O D Y R E C O M P O S I T I O N
General Use Supplements: Part 1 Protein Powders
- Useful for athletes who have trouble meeting high requirements - Convenience/portability/around workout nutrit ion - Whey/casein/milk protein isolate - Do NOT buy commercially
Basic multivitamin/mineral - Men should be aware of iron overload - Women should choose iron containing product
Fish oils: A MUST! - Pills or liquids both acceptable - Flax oil: not ideal - Fatty Fish - 1.8-3.0 g/day active EPA/DHA (-6-10X1 gram capsules)
B O D Y R h C O M P O S ! H O N
B O D Y R E C O M P O S 1 T I O N
General Use Supplements: Part 2 Calcium
Especially for female athletes - 800-1600 mg/day, calcium citrate
Vitamin D - May be as important as fish oil
Problem in northern latitudes Ideal to get blood work first. If not 2-4k IU per day. Consider tanning lX/week (seriously)
Zinc/Magnesium - Commonly deficient in athletes - Helpful for sleep taken at bedtime
Magnesium oxide is poorly absorbed (citrate better) Dose 25 mg zinc/400mg magnesium

-
General Use Supplements: Part 3 Glutamine
May protect immune system function High quality proteins/BCAA work better
- Purely empirical: when starting to get sick, horse doses of glutamine and Vitamin C help to kill it. Take 2-3 grams glutamine and 500mg Vitamin C as often as you remember.
Anti-oxidants In isolated form, do not appear to improve performance or health In diet, they improve health
- Excessive anti-oxidant intake from pills may impair training adaptations
B O D Y R E C O M P O S I T I O N
Performance Supplements: Part 2 Beta-Alanine
May help lactic athletes buffer - May increase work capacity in weight trainers, esp.
combined with creatine - 400-800 mg 4X/day (pain in the ass) for 30 days
min imum - Can cause a histamine flush (tingling, burning)
Branched-chain amino acids - Very popular with bodybuilders
Mixed results in the literature in terms of performance - IMO: Unnecessary if sufficient protein being consumed
Pre-workout stimulants Good old caffeine: 3-5 mg/kg 30-60 minutes before
- Be careful with fat burners, can cause cramping B O D Y R E C O M P O S I T I O N
-
Creatine Monohydrate Must have for strength/power athletes Does increase body weight by l-2kg (water)
- May improve repeated sprint performance - Loading approaches
20 g/day for 5 days (fastest but can cause stomach upset)
10 g/day for 10 days (longer but less GI issues) 3 g/day for 30 days (longest but no chance of
stomach upset) End result is the same
Creatine monohydrate is fine, expensive products are only more expensive, not better. Maintain with 3-5 g/day before/after heavy workouts
B O D Y R E C O M P O S I T I O N
Esoterica Everything else There are a zillion supplements that might or might not do
something In 20 years in the field, I've seen thousands come and go. Most go. Few live up to the hype and they are the one still being used a year later. When you have everything else dialed in on a day to day
basis, consider this stuff. Until then, focus on what matters.

Buying Supplements Companies I Personally Use Never buy commercially (e.g. GNC) Online always cheaper although shipping/import can affect
that Get together with teammates and order in bulk to defray
shipping costs
B O D Y R E C O M P O S I T I O N
Irueprotein.com (http://www.trueprotem.com) Excellent for bulk protein and other supplements 5% discount for orders over 16 lbs. No duty or brokerage fees
lfast400.com (http://wwwJiasl400.com) Bulk powders and other daily use supplements Fast shipping, good prices
Vitaglo.com (http://www.vitaglo.com) Not so fast shipping sometimes Excellent prices
B O D Y R E C O M P O S I T I O N
Gaining Muscle: Part 1 Requires a surplus of calories AND building blocks
Can't make muscle out of thin air and wishful thinking
Module 7: Changing Body Composition
Proper training program: sufficient volume and frequency
Surplus around weight training workouts
Athletes seeking mass gains should use the higher values for post-workout nutrition listed in the handout

v v v v m v \ \ \ \ \ \ \ i i i i i i i i i i i i i i i i i n T T i T r n n n t > 1 Gaining Muscle: Part 2
Actual rate of muscle mass gains is slow - 1 kg/month or less for non-beginner males - 0.5 kg/month for non-beginner females
At most a 300-500 cal/day surplus on training days Female athletes may need 200-300 over maintenance
Calories beyond what is needed for maximal growth will just make the athlete fat
B O D Y R E C O M P O S I T I O N
Fat Loss: Part 2 Creating a deficit
- Caloric restriction vs. increasing activity Extensive tempo, low intensity work, etc. can burn calories to create deficit without hurting training
Where to cut calories Never protein Carbs vs. fats What about around workout nutrition
Fat Loss: Part 1 Requires a caloric defici t
No amount of food shifting and combining can get around this
Fast vs. slow fat loss: pros and cons - In general, slower will hurt performance less
Faster gets the diet over faster
H o w m u c h fa t is t h e a th l e t e car ry ing Fatter can lose faster than leaner
B O D Y R E C O M P O S I T I O N
