caution

be tired

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
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”
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
Teen Athletes cont.
• Steroids
– Artificially (anabolic steroids) produced
hormones that stimulate muscle tissue
to grow
• See website for more information:

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!

Obesity and Dieting
• Obesity in adolescence is often a result of
childhood obesity (overfeeding during infancy
and childhood).
– Poor self esteem/concept excludes an adolescent from a
social life

– Losing weight as an adolescence is more difficult than
in childhood because adolescence have more control
over what they eat and they have to make the decision
to lose weight themselves
Obesity and Dieting cont.
• Many adolescence turn to dieting as a way to
fight obesity.
– This can become dangerous because many
adolescence see smoking as a quick way to drop a few
pounds since it is an appetite suppressant
– Teens also turn to drugs such as pot and cocaine
because of their relation to weight loss
