3. Nutritional Risk Iron Prevents anemia (especially in females)
Teen females need about15 mg / day
Teen males need about 12 mg /day
Females need more due to menstruation
Sources include meat, poultry, fish, cereal, beans, leafy greens and green vegetables.
Vitamin C sources such as fruits help absorb Iron
Caffeine blocks absorption

4. Teen Athletes
Muscle is built by exercise not by eating extra protein or taking supplements
Supplements should be used with caution
These supplements work only with EXERCISE

5. Teen Athletes cont. Common supplements include: Caffeine (Ephedra)
Basically burns fat (increases metabolism) and does not cause you to be tired
Side effects include heart palpitations, inability for the body to properly cool itself, nervousness, irritability, dehydration , diarrhea, possible death
Creatine
Increases muscle fullness and body mass
Side effects include dehydration due to muscles retaining water
Protein
There are two types: whey and egg
Whey includes all the essential amino acids
Side effects include excessive gas and bloating due to improper digestion

6. Teen Athletes cont,
Nutrient-dense foods are required because of high energy output.
An apple is nutrient dense, not a candy bar
Meals should be eaten 3-5 hours before an athletic event
While carbohydrates give you energy, be aware that you do not want to feel to “full”

7. Teen Athletes cont.
Water is essential and should be consumed before, during and after physical activity
2 cups of water is recommended for every pound lost during a workout.
Electrolyte drinks should be consumed after physical activity, not during because your body will need replacements
Electrolytes such as potassium and sodium are electrically charged ions that are important to body functions

8. Teen Athletes cont. Steroids
Artificially (anabolic steroids) produced hormones that stimulate muscle tissue to grow

9. Other Exercise Tips
Just because you sweat during exercise does not mean you are “burning more calories.”
Sweating is just your body’s way of cooling down…it’s your own personal air conditioner.
Do not wear plastic suits that cause you to sweat more…these are dangerous because your body can’t cool itself and/or breathe.
There is no true “good time” to exercise.
You have to find a time that is good for you and works with your schedule.
It is recommended to exercise for 30 minutes a day.
Even if you park far away from the store, the point is to get up and move!
