Nutrition for Adolescent Athletes
Fluids and Hydration
Young adolescents present a particular vulnerability to heat illnesses because their bodies
do not regulate their body temperature as well as those that are older.
They do not pay attention to the signs of fluid loss such as sweating and thirst.
Should regularly consume fluids even if they do not feel thirsty.
Should consume 6-8 ounces prior to exercise, 4-6 ounces every 15 to 20 mins during
activity and at least 8 ounces following exercise.
Each pound of activity lost during activity requires ingestion of 16 ounces of fluid to
maintain proper hydration.
Should drink no more than 16 oz of fluid each 30 mins to avoid nausea.
Sport drinks that contain no more than 6-8% carbohydrate may allow for better hydration
and performance higher than that causes gastric discomfort.
Special Dietary Practices
Carbohydrate loading- done by runners and endurance athletes as a week long process
that begins with intense training 1 week prior to competition, then the first three days
they choose low carbohydrate foods but keep exercising in attempt to deplete muscle
glycogen stores. Three days before competition they rest while consuming high
carbohydrate levels to promote glycogen formation and storage.
High protein diets- May consume 3-4 times the recommended protein intake with a low
intake of carbohydrates. These should be discourage because many protein sources are
sources of total and saturated fats which could increase risk of coronary artery disease
and because of the reduced carbohydrate intake this may delay digestion and absorption
limiting amount of energy available, and puts athlete at risk of dehydration because
water is breaking down protein.
Dieting, Disordered Eating, and Eating Disorders
The Continuum of Eating Concerns and Disorders
Continuum from mild dissatisfaction with body to serious eating disorders (anorexia,
bulimia, binge eating disorder).
Body dissatisfaction-> Dieting Behaviors -> Disordered Eating -> Clinically significant
eating disorders. Dieting Behaviors
Dieting decreases as males get older and increases as females get older.
Adolescents who reported unhealthy weight control behaviors were more likely to be
overweight in the future.
Dieting behaviors have been found to be associated with inadequate intakes of essential
Need to focus on long term healthy diet changes not short term dieting.
Dieting should not be viewed as a normative and acceptable behavior particularly among
Body image concerns should not be viewed as acceptable or normative components of
Body dissatisfaction contributes to dieting behavior, disordered eating behaviors, and
clinical eating disorders.
