Profiling Yourself

Do you know how many calories YOU should eat a day to sustain life?

How many calories do you burn per workout? Do you know the recommended breakdown of;

Carbohydrates/Proteins/Fats? Do you know the difference between a Linear and a

Round Diet? If not, how do you determine how much to eat daily? How fluids of water is needed daily or following a high

sweat workout? What foods can you eat to get all your fluid intake?

Fueling the Machine

In Humans >90% of Caloric Intake is based on 2 factors: Metabolic Process (Cell Function, Organs, etc.) Physical Activity

The Food Guide Pyramid is the basis of dietary needs in the US. It is updated every 5 years. Based on Caloric Needs of; Age, Gender, Height,

Weight and Activity Level. www.MYPYRAMID.gov

Pros Increased Vitamin and

Mineral Intake Increased Immune Function Fast Recovery Weight Control

Cons New Recipes

Linear Diet Repetitive Eating

Shopping List Generally Consists of The Same 10-15 items.

Pros Simple Shopping Minimizes Decisions for

Meals Cons

Function

Your Weight; Maintain, Lose or Gain

Endurance Sport = Weight-to-Strength Ratio Lohman Equation – Designed by the sports nutrition

community to reliably determine nutritional needs for athletes;

(9 x Wht in Kg) + 11.7 x Ht in cm) – 857=RMR 175lb (79.5kg) Athlete, 5’11” (180.3cm) (9 x 79.5) + (11.7 x 180.3) – 857=1,965/Kcal/da 1,965 x 1.6 = 3,144/kcal/day

lbs to kg = 175 ÷ 2.2 = 79.5kg In to cm = 71 x 2.54 = 180.3cm

Once RMR is established, apply a multiplier to account for activity level;

1.3 for Inactive (≤30min/day) 1.6 for Moderately Active (30 to 60min/day) 2.0 for Vigorous Activity (≥60min/day)

ADA Recommendations

Five Rules to Control Weight Establish Caloric Needs and Goals

Utilize the Lohman Equation Utilize a Online Tracker

www.livestrong.com, www.dailyplate.com, www.webmd.com Increase Meal Frequency

Weight control is based on Calories-In vs. Calories-Out, NOT eating time, carbohydrates or # of meals.

Multiple Meals is highly recommended, but not always feasible or necessary.

Maintain a Balanced (Round) Diet Review ‘Round vs. Linear’ Slide

Talk About It Post goals, share with friends or teammates helps to make

the goal ‘Concrete’ and increases chances of success

Hydration 101

Sweat Factors Sport, Body Size, Intensity, Clothing, Weather,

Acclimation to Weather and Fitness Level Weight loss can exceed 20lbs/hr

How do you know if you are hydrated or chronically dehydrated; Weigh Nude Daily in the Morning

Empty Bladder and Bowels Factors that affect test; Calorie Restriction, Low

Sodium Intake Night Before, Not Experiencing Premenstrual Bloating

Page 10: Nutrition and the Endurance Athlete ‘We eat to train, we don’t train to be able to eat.’ – Bob Seebohar Jack F. Parker Jr. NSCA-CSCS ACSM-HFS USAT Level.

Hydration 102

Dehydration Symptoms (Fatigue, Headaches, Lethargic Sodium – 1qt Gatorade (440mg) Potassium – 1md Banana (450mg) Calcium – 8oz Yogurt (300mg) Magnesium – 2 tbsp Peanut Butter (50mg)

Thirst mechanism is unreliable Blunted by exercise or mind Thirst is associated with;

1% loss of water = 1.5lbs or 3 to 5 heart beats/min 2% loss of water ≥ 3lbs or Clinically Dehydrated 3% loss of water ≥ 4.5lbs or Impaired Aerobic Performance

Pre-Exercise Fluids

Hydration Practices Begin 8 to 12 Hours in Advance Pre-hydration Goal is To Consume 2 or 3 ml/lb

or 5 to 7ml/kg 4 Hours in Advance of Exercise to Balance Body

150lb (68kg); 150 x 2 = 300 - 450ml or 10 to 15oz Hydrating Early Allows for Absorption and

Clearance of Un-needed Fluids *Don’t Over Hydrate, This Dilutes Blood-Sodium and

Causes Hyponatremia 12oz of Caffeinated Coffee Is Ok, It Will Not Boost

Daily Urine Output.

Hydrating During Exercise

Goal is To Prevent Excessive Dehydration; Defined by More Than a 2% Body Weight Loss Knowing Your Sweat Rate Helps to Answer

the Following Questions; What to Drink?

Fluid Replacer Should Contain; Sod – Stimulates Thirst (110-170mg per 8oz) Pot – Sweat Loss (20-50mg per 8oz) Carb – Provides Energy (12-24g per 8oz)

Page 13: Nutrition and the Endurance Athlete ‘We eat to train, we don’t train to be able to eat.’ – Bob Seebohar Jack F. Parker Jr. NSCA-CSCS ACSM-HFS USAT Level.

Hydrating During Exercise (Cont.)

When to Drink? Determined By Length of Workout

≤ 60 Minutes – Water Suffices 2 or More Hours - 120 to 240 Carbohydrates with

Water (30 to 60g) Sports Drinks, Fruit, Boiled Foods

Page 14: Nutrition and the Endurance Athlete ‘We eat to train, we don’t train to be able to eat.’ – Bob Seebohar Jack F. Parker Jr. NSCA-CSCS ACSM-HFS USAT Level.

Post-Exercise Fluids

Goal is to Fully Replace Fluid/Electrolyte Loss Single Workout Day

Normal Meals Following a Round Diet Double/Triple Workout Day

Normal Meals Sprinkle Extra Salt (Not for High Risk Individuals) Supplement Drink 50% More Fluid Than Lost

Fluid Recovery Can Take 48 Hours for BT Workouts

Page 15: Nutrition and the Endurance Athlete ‘We eat to train, we don’t train to be able to eat.’ – Bob Seebohar Jack F. Parker Jr. NSCA-CSCS ACSM-HFS USAT Level.

Hyponatremia and Sodium Loss

Over-Hydrating vs. Hydrating Kidneys Regulate Fluid Intake

Hydrate Up to 2 Hours Before Events, Then 15 Minutes Before Race Start

Hyponatremia Means Blood-Sodium Levels Become Abnormally Low

Events Less Than 4 Hours Over-hydrating Before, During and After Event

Events Longer Than 4 Hours Extreme Sodium Loss Heat Environments, High Water

Intake, Look for Supplements or Foods Containing 250-

500mg of Sodium Per Hour Heat Acclimated Athletes Have the Ability to Retain

Higher Sodium Amounts

Deciphering Supplements FDA regulates dietary supplements under a different set of regulations

than those covering "conventional" foods and drug products (prescription and Over-the-Counter). Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), the dietary supplement manufacturer is responsible for ensuring that a dietary supplement is safe before it is marketed. FDA is responsible for taking action against any unsafe dietary supplement product after it reaches the market. Generally, manufacturers do not need to register their products with FDA nor get FDA approval before producing or selling dietary supplements.* Manufacturers must make sure that product label information is truthful and not misleading.

FDA's post-marketing responsibilities include monitoring safety, e.g. voluntary dietary supplement adverse event reporting, and product information, such as labeling, claims, package inserts, and accompanying literature. The Federal Trade Commission regulates dietary supplement advertising. Most Actions are taken following a series of catastrophic instances. If reports are not filed, then the FDA doesn’t know about them.
