COMMON NUTRITION MISTAKES: COMMON NUTRITION MISTAKES Not drinking enough fluids
Not choosing the most appropriate fluids
Eating sporadic meals
Being inconsistent with eating day to day
Not eating enough calories
Not getting a good balance of foods/nutrients ( carbohydrate, protein, and fat)
COMMON NUTRITION MISTAKES: COMMON NUTRITION MISTAKES Making food choices that hurt performance
Waiting too long to refuel after exercise
Making drastic changes in diet to alter body composition and body image
SPORTS NUTRITION FACTS: SPORTS NUTRITION FACTS Athletes need to know:
What to eat and drink
When to eat and drink
How much to eat and drink
Reality check on body issues
Straight answers on the use of supplements
GOALS OF SPORTS NUTRITION: GOALS OF SPORTS NUTRITION
Mental clarity
Optimal performance
Faster recovery
Injury prevention
Adequate hydration
NUTRITION FACTS: NUTRITION FACTS We eat FOOD, NOT nutrients
Athletes need carbohydrate, protein and fat-containing foods daily
We can be selective about the types of foods we choose to eat:
Fish instead of meat
Kashi instead of Froot Loops
Peanut butter instead of bacon
ISSUES: ISSUES Eating is NOT always a priority
Information overload, most of it is negative!
Busy lives translate to poor eating practices
External messages ( from magazines, TV, movies, that portray the “ideal” body)
Effect of eating/body issues on team dynamics
BODY IMAGE ISSUES: BODY IMAGE ISSUES Do NOT have one cause, so everyone who is involved with the athletes needs to be part of the treatment
Destroys focus of the affected athlete, team, roommate, friends, coach and administrator
DO need an action plan that is PROACTIVE, NOT REACTIVE
BODY REALITY CHECK: BODY REALITY CHECK What you CANNOT change
Height
Body Frame ( Bone density)
Body shape ( where one tends to concentrate weight)
What you CAN change
Fluid content of the body
Muscle Mass
Body fat
BODY REALITY: BODY REALITY
Body loses fat at about ½ pound per week
Body gains muscle at a rate of about 1 pound per week
Changes do NOT happen overnight
Need to be consistent
A STARTING POINT: A STARTING POINT Set your own nutrition goal
Do it for you, NOT for someone else
Realistic and achievable
Lose body fat, gain mass, or maintain weight
Increase energy
Prevent muscle cramps, headache or upset stomach while exercising
ROLE OF FLUIDS: ROLE OF FLUIDS Being dehydrated
muscle strength
speed
stamina
energy
cognitive skills
risk of injury
perceived effort of exertion
ROLE OF FLUIDS: ROLE OF FLUIDS Being over hydrated:
headache
gastrointestinal distress
respiratory distress
nausea and vomiting
confusion
lethargy
ISSUES: ISSUES Exercise may suppress thirst mechanism
Thirst is NOT the best indicator of adequate hydration
Supplements such as ephedra, synephrine, and herbs including saw palmetto, buchu, nettle and lovage may dehydrate the body
High protein diets lead to excessive fluid loss which may be dehydrating
ISSUES: ISSUES Some athletes assume that the weight lost during exercise is fat loss BUT it is fluid loss and needs to be replaced!
MORE is NOT always better when it comes to fluid as there is an upper limit that the body can tolerate!
FLUID CHOICES FOR EXERCISE: FLUID CHOICES FOR EXERCISE
BEST: sports drink, water, milk, soup, fruits, vegetables
NOT AS GREAT: carbonated beverages, high carb energy drinks, alcohol, juices
NEUTRAL: caffeinated beverages
HOW MUCH?: HOW MUCH? 2 cups (sports bottle size) 1-2 hrs BEFORE practices/games
8 oz 15 minutes BEFORE practices/games
20-40 ounces ( 1-2 sports bottles) per hour of exercise
3 cups (1-1/2 sports bottles) for every pound lost AFTER practices/games
IMPLEMENTATION: IMPLEMENTATION Drink on a schedule
Bring a water/sports bottle to practice/workouts
Weigh in and out to determine your own fluid loss during exercise
GULPS over SIPS for more effective rehydration
First urine of the morning should be light in color and plentiful- this is an indicator of being well hydrated
SALT LOSERS: SALT LOSERS IF:
Your sweat stings your eyes
Your skin/uniform are coated with a white residue after practices/games
THEN:
Use more salt on foods
Eat salty foods
Don’t overdo with water
WHAT TO EAT?: WHAT TO EAT? Peace sign eating:
2/3 of the plate as carbohydrate foods:
Bread,bagels, cereal, rice, pasta, sweets, fruit, vegetables, crackers, pretzels, beverages
1/3 protein:
Meat, poultry, fish, dairy foods, nuts, seeds, soy foods, dried beans, eggs
ISSUES: ISSUES Belief that certain foods are BAD
Bodies cannot perform well on fumes
FACT: Carbohydrate and fat are the primary fuel substrate for exercise
(these two nutrients are essential for endurance and sprint type exercise)
ISSUES: ISSUES Protein is important for muscle growth and repair but is an inefficient fuel source for exercise
The maximum protein intake should be 1 gram per pound body weight
The minimum protein intake should be 0.5 grams per pound body weight
TIMING: TIMING Breakfast is a must!
Something to eat/drink every 3-4 hours
Meal 3-4 hours BEFORE games
Snack 1 hour BEFORE games
Carbohydrate food/fluid DURING practices/games
Carbohydrate food/fluid within 15 minutes AFTER practices/games
POST EXERCISE CARBOHYDRATE FOOD CHOICES: POST EXERCISE CARBOHYDRATE FOOD CHOICES 32 oz sports drink
2 granola bars
2 cereal bars
A handful of dry cereal
An 8 oz yogurt
A handful of pretzels and a banana
IMPLEMENTATION: IMPLEMENTATION
Eating needs to be scheduled and prioritized
There is NO such thing as PERFECT eating
Make it available by bringing food/fluid to practices/games so that you can fuel before, during and after practices and games
ACHIEVING WEIGHT GOALS: ACHIEVING WEIGHT GOALS To lose weight effectively
Know what you eat by writing down for 3-4 days what, how much, when, where and why you eat
Do eat on a regular basis, every 3-4 hours
Do try to watch what you eat most days of the week
Try to decrease calories from beverages, including juice, alcohol, carbonated beverages
TO LOSE WEIGHT: TO LOSE WEIGHT Watch your portions- try to eat a little less at every meal or snack
Sit down when you eat
Include items that are more filling such as meats, soups, vegetables
Stay away from fad diets- the weight loss is mostly water, and you’ll be too tired to exercise
TO INCREASE MUSCLE MASS: TO INCREASE MUSCLE MASS Do eat on a regular basis- every 3-4 hours
Do try to eat a little more every time you eat
Do try to eat more every day, not just a few days a week
Do increase calories from beverages as well as foods
TO INCREASE MUSCLE MASS: TO INCREASE MUSCLE MASS
Do increase the calories in foods:
Nuts instead of pretzels
Granola instead of corn flakes
Bagel instead of bread
SPORTS SUPPLEMENTS: SPORTS SUPPLEMENTS Need to know what you are putting in your body
NOT ONE SIZE FITS ALL
There are hyper and nonresponders to supplements, in otherwords, some athletes will benefit from taking a supplement in terms of strength, speed and stamina, whereas other athletes may not notice a difference in performance
SPORTS SUPPLEMENTS: SPORTS SUPPLEMENTS Natural and safe are NOT the same
Supplements can interfere with medications
More is NOT BETTER
Tell someone what you take, or are planning to take
Be informed, and be cautious with supplements, as what you don’t know may hurt you!
BOTTOM LINE: BOTTOM LINE Food, fluid, and rest are essential for peak mind and body performance
Food choices, timing, and amounts matter
Focus on what your body ALLOWS you to do
POSITIVE environments
