Student-Athlete Nutrition Handbook
Dear
Parent/Guardian and Student-Athlete:
In today’s world of competitive secondary school
athletics, young men and women place a high physical
demand on their bodies. From weight lifting to speed
and agility training, they look to gain every possible
advantage over their opponents. Throughout the year,
they participate in interscholastic practices and games,
off-season training, and club team workouts. Yet, despite
all this activity, the role of proper nutrition in achieving
athletic success is frequently overlooked.
Imagine what would happen to your vehicle if you did
not give it the proper fuel, care, and maintenance it
required. Eventually, it will stop performing at the
level you expect, and ultimately, it will break down.
Our bodies necessitate the same attention in order to
reach our peak potential in the athletic arena. Unfortunately,
too many student-athletes fuel their bodies incorrectly.
Fad diets, fast food, candy bars, and greasy snacks
do not provide the energy needed to deliver peak performance.
This handbook, which has been compiled from a wide range
of resources, is intended to provide basic nutritional
guidelines for athletes – young and old. Learning
to make intelligent eating decisions will not only give
you the edge needed to compete on the playing field,
but also provide you with a lifetime of health and wellbeing.
Please be sure to consult a Registered Dietician or
your Certified Athletic Trainer before starting any
diet. If you have any questions, please feel free to
contact me at 610-390-4260 or tdoane@coordinatedhealth.com.

Energy and NutrientsCarbohydrates:
o Carbohydrates provide fuel for the body.
o A diet low in carbohydrates will cause fatigue and
decreased concentration, resulting in decreased athletic
performance.
o Sources include grains, bread, cereal, rice, pasta,
fruits, and vegetables.Proteins:
o Proteins are needed for cellular growth and repair,
normal enzyme and hormone functions, antibody production,
fluid and electrolyte balance, and proper acid/base
balance.
o A diet high in protein can be harmful to these processes.
o Sources include meat, poultry, fish/seafood, legumes,
dairy products, eggs, seeds, and nuts.Fats:
o Fats provide a source of stored energy, serve as insulation
for the body, cushion vital organs, and transport vitamins
and fatty acids.
o A diet high in fat will adversely affect body composition,
cause sluggishness, and rob muscles of energy needed
for athletic performance.
o A low-fat diet is one that consists of 20-25% fats.
o Sources of quality fats include plant-based fats (i.e.
olive oil, nuts, seeds) and lean protein-based fats
(i.e. lean roast beef, fish/seafood, poultry, eggs).Recommended
Distribution of Calories for Peak Performance:
A healthy, well-balanced diet provides all the body
needs to function at its peak. Similar to different
positions on an athletics team, each nutrient has a
purpose. Just as a basketball team would suffer without
a point guard, a football team would fail without offensive
linemen, and a soccer team would be unsuccessful without
defensemen, a diet will fall short if the components
are not present in the proper proportion. Variety, moderation,
and wholesomeness are three keys to choosing meals and
snacks for healthful eating. The following is the recommended
distribution of nutrients for achieving peak athletic
performance.
o 55-65% Carbohydrates
o 20-25% Fats
o 15-20% Proteins
Basic Nutrition GuidelinesGuidelines to Assist You in
Decreasing Body Fat:
o Eat more times per day, but less per meal.
o Be consistent with meal times; keep plenty of variety
in food selection.
o Broil, bake, or barbecue all meats.
o Eat more chicken (skinless) and fish.
o Eat lean cuts of meat only.
o Consume low-fat dairy products.
o Eat three to four pieces of fruit daily.
o Eat raw, steamed, or boiled vegetables.
o Reduce the amount of butter or margarine consumed.
o Reduce the amount of red meat consumption.
o Drink eight 8 ounce glasses of water daily.Consuming
Complex Carbohydrates:
o Increases energy storage in muscles.
o Increases protein-sparing effect; protein will be
used for growth and repair rather than for energy.
o Increases endurance.
o Increases rate of recovery from a practice session.Foods
High in Complex Carbohydrates:
o Bread and rolls
o Cereal (good quality, no sugar added)
o Pancakes and waffles
o French toast
o Pasta
o Rice
o Vegetables (potatoes, sweet potatoes, lima beans,
peas, corn, etc.)
Nutrition Guidelines for Peak Athletic Performance¸
DO eat three meals per day (when weight gain is desired,
there should be an additional two or three snacks).
Three meals help maintain muscle tissue, promote the
reduction of body fat, and reduce sluggishness and the
onset of fatigue.
¸ DO eat breakfast. It is the most important meal
of the day. Skipping breakfast will likely cause you
to concentrate less effectively in the late morning,
work and study less efficiently, feel irritable and
short-tempered, or fall short of energy for your afternoon
practice/game.
¸ DO increase intake of complex carbohydrates:
bread, cereal, pasta, rice, pancakes, waffles, potatoes,
sweet potatoes, lima beans, peas, corn, winter squash.
This allows for prolonged endurance, increased energy
storage in muscles, and a protein-sparing effect for
the growth and repair of muscles.
¸ DO increase the consumption of fruits and vegetables.
They are high in vitamins, minerals, water content,
and are often a good source of carbohydrates.
¸ DO buy lean cuts of meat and trim all excess
fat. Eat only moderate portions - the size of your palm
is a good rule of thumb. Substitute chicken or poultry
for red meat when possible.
DON’T consume a high quantity of foods that are
high in fat: red meats, pork products, whole milk, ice
cream, cream sauces, butter, or margarine, mayonnaise,
salad dressing, oils, fried foods, fast foods. A diet
high in fat and low in carbohydrates slows the process
of energy storage in the muscle. It can lead to an increase
in body fat, a decrease in muscle tissue, chronic exhaustion,
irritability, and restlessness.
DON’T skip meals to lose weight. This practice
will prevent energy stores in the muscles from being
replenished.
DON’T replace meals with refined sugars: candy,
cake, cookies, soda. Foods high in refined sugar have
a lower vitamin and mineral content and are often high
in fat.
DON’T fry foods. You should bake, broil, boil,
poach, steam, or barbecue the food instead.
DON’T consume soda, iced tea, hot tea, coffee,
or other caffeinated drinks (i.e. Red Bull, Krank’d,
etc.). These beverages contain diuretics that can cause
dehydration, heat cramps, and heat illness. They will
also negatively affect reaction time, hand-eye coordination,
accuracy, balance, strength, and endurance.
WaterWater, the most commonly overlooked nutrient, is
very critical to athletic performance. Adequate fluid
intake before, during, and after exercise is imperative
to prevent dehydration. The primary role of water is
to hydrate the body for normal metabolic processes.
It is important for athletes to maintain normal body
temperature during exercise. A two percent loss of body
weight through sweating can adversely affect performance.
During hot weather, it is even more important to drink
plenty of water before, during, and after exercise.
Cool water is the best fluid choice. Consuming sport
drinks (i.e. Powerade, Gatorade) containing less than
six to seven percent carbohydrates during activity may
provide benefit only when intense exercise lasts longer
than forty-five minutes. Beverages containing greater
than eight percent carbohydrates (i.e. fruit juice,
fruit drinks, soda) are not recommended during activity,
as they will increase emptying time from the stomach,
delay fluid absorption from the intestines, and predispose
you to dehydration, heat cramps, and heat illness.The
following table provides recommendations for adequate
fluid consumption:TIME
FLUID CONSUMPTION
Throughout the day
Drink fluids frequently: water, Powerade, Gatorade (avoid
soda, iced tea, hot tea, coffee, or other caffienated
beverages - they contain diuretics)2 hours before event/exercise
2 _ or more cups15 minutes before event/exercise
2 _ cupsDuring exercise
_ to 1 cup at 10-15 minute interval throughout eventAfter
exercise
Replace weight loss with fluids; 16 ounces of fluid
(water, Powerade, Gatorade) for every pound of weight
lost Pre-Competition MealsPre-competition meals are
a vital part of an athlete’s preparation. The
meal should consist primarily of carbohydrates while
limiting fats and proteins. Carbohydrates can be converted
quickly into glycogen, which is used as energy. Fats
and protein, on the other hand, usually slow intestinal
motility and can take hours to digest. Fat does not
provide a rapidly usable source of energy and high levels
in the bloodstream can reduce carbohydrate uptake into
the muscles.
The pre-game meal should be approximately 4 hours before
competition to allow for adequate digestion. Food should
be baked or broiled – not fried. Fried foods are
high in fat because they soak up the fat from the oil
in which they are cooked. The following are sample pre-game
meals for breakfast and lunch/dinner.Breakfast:
o French toast
o Potatoes (with no onions)
o Fluffy scrambled eggs
o Toast
o Pastry
o Fruit juice
o Syrup
o Butter/Jam
o Beverage Lunch/Dinner:
o Boneless breast of chicken
o Pasta (i.e. spaghetti, ziti)
o Green vegetables
o Baked potato
o Italian bread
o Butter
o Salad
o Beverage
Post-Exercise NutritionCarbohydrates:
What you eat and drink after practice/competition can
affect your recovery rate. This applies to daily training,
practices, games, or multiple events throughout a single
day. Post-exercise food and drink should be chosen as
carefully as you select your pre-competition foods.
Exercise depletes muscle glycogen. Therefore, it is
important to consume foods high in carbohydrates following
activity. Resynthesis of muscle glycogen will help you
recover from the previous exercise session and prepare
you for the next session. Long-term muscle glycogen
depletion may result in fatigue and/or headaches and
decreased performance levels. High carbohydrate foods
and beverages should be consumed within one to four
hours after exercise. The appropriate intake of carbohydrates
is 0.5 grams/pound of body weight (1 gram of carbohydrate
contains 4 calories) within the first two hours following
activity and again during the second two hours after
exercise.
Example:
150 pound athlete
150 lb. x .5g carbs/lb = 75g carbohydrates
1g carbohydrate contains 4 calories
4 calories/g x 75g carbs= 300 calories
Therefore, the 150 pound athlete would need to consume
75 grams, or 300 calories, of carbohydrates within the
first two hours and again during the second two hours.
Quality Recovery Foods:
o Bagel, plain (1 bagel = 200 calories)
o Banana (1 banana = 105 calories)
o Bread, white (1 slice = 60 calories)
o Carrots, cooked from raw (1 cup = 70 calories)
o Corn, cooked from frozen (1 cup = 135 calories)
o Green beans, cooked from frozen (1 cup = 35 calories)
o Orange juice (8 ounces = 110 calories)
o Pizza, cheese (1 slice = 290 calories)
o Potato, baked with skin (1 potato = 220 calories)
o Pretzels, thin twisted (10 pretzels = 240 calories)
o Raisins (_ cup = 218 calories)
o Rice, cooked white (1 cup = 225 calories)
o Saltines (4 crackers = 50 calories)
o Spaghetti, cooked tender (1 cup = 155 calories)
o Vegetable beef soup (8 ounces = 80 calories)
Gaining Weight and Building MuscleThere is much information
written on ways to increase lean body weight and build
muscle. What really works? What is correct? It becomes
very confusing. The purpose of the following guidelines
is to help you understand this complex subject.Building
Muscle Mass is Influenced by Three Major Factors:
o Genetics – Heredity plays a role, but through
hard work and diet, you can increase the size and strength
of the muscle fibers you have inherited.
o Exercise – Resistance training can help you
build larger and stronger muscles through specificity,
overload, and progression.
o Nutrition – In order for your exercise to provide
the desired results, your body must be properly fueled.Proper
Weight Gain:
Popular opinion is that protein is the most important
nutrient in building lean body mass. The fact is that
muscles are comprised of only 22% protein and 70% water.
Protein requirements are increased when weight gain
is desired. However, this increase is relatively small.
The primary source of calories for building muscle should
be carbohydrates.
The body builds muscle in the same way a house is built
on a construction site. In both cases, two components
are required – the materials with which the structure
is being built, and the manpower needed to build it.
In the body, protein is the main building block for
enhancing muscle mass. However, if there is no manpower
in the form of carbohydrates, the excess protein ingested
goes to waste, ultimately being stored in your body
as fat.
In order to gain one to two pounds of muscle mass per
week, a person must increase their daily caloric intake
by 500 to 1000 over what is normally required for body
maintenance and athletic activity. Weight gain greater
than this may potentially become body fat. The following
is the recommended distribution of nutrients for gain
lean body mass.
o 50-60% Carbohydrates
o 20-25% Proteins
o 20-25% FatsProtein Requirements for Increasing Lean
Body Mass:
The normal daily requirement for protein is 0.36 grams/pound
of body weight. For a person who desires to increase
body mass, the appropriate intake of proteins is 0.68
grams/pound of body weight (1 gram of protein contains
4 calories).
Example:
150 pound athlete
150 lb. x 0.68g proteins/lb = 102g proteins
1g protein contains 4 calories
4 calories/g x 102g proteins = 408 calories
Therefore, the 150 pound athlete would need to consume
102 grams, or 408 calories, of protein daily to increase
muscle mass. This is the total protein that should be
consumed daily within the proper distribution of nutrients
for proper weight gain (listed previously).Undesired
Side Effects of Excessive Protein Ingestion:
o Increased fat storage
o Increased dehydradration
o Gastrointenstinal disturbances (i.e. bloating, cramps,
diarrhea)
o Kidney damage
o GoutHow to Gain Weight:
o Assess your current eating habits. Your intake can
be determined by a Registered Dietician or you can calculate
it on your own with the assistance of your Athletic
Trainer.
o Increase the number of calories you consume.
o Substitute non-caloric beverages (i.e. water, diet
soda) with beverages containing calories. Suggested
choices include 100% fruit juice, skim or low-fat milk,
yogurt shakes, and fruit smoothies.
o Substitute low-calorie foods with high-calorie foods.
o Eat more at each meal.
o Eat three meals and several healthy snacks per day.
o Eat a healthy dessert.
o Allow healthy fats into your diet to provide extra
calories.
o Eat quality proteins. Suggested choices include lean
roast beef, fish/seafood, and poultry.
o Resistance training and exercise - increasing calories
without working out will only lead to increased body
fat and decreased athletic performance. Body Composition
There are commonly misconceptions among student-athletes
regarding health body composition. Body fat percentages
are not meant to be the defining factor of health.
Women should also be aware that a healthy body composition
is also determined by the presence of a normal menstrual
cycle. For example, a female who has 17% body fat but
no regular cycle would still be considered to have low
body fat. Absence of a normal cycle may be caused by
caloric deficiency. Caloric deficiency can lead to protein
wasting, which will result in a skewed body fat percentage.
This is one of the primary triggers of the Female Athlete
Triad, which is comprised of energy deficit, amenorrhea,
and osteoporosis. If you have any questions or concerns,
please consult a Registered Dietician or your Certified
Athletic Trainer. Male

o 27-31% – Above Normal Fat
o 17-27% – Average Fat
o 14-17% – Very Low Fat

o <11% – Unhealthy
Sport and Nutritional SupplementsSearching for the Edge:
Every year, student-athletes continue to search for
the edge in everything they do – from pre workouts,
lifting programs, recovery regimens, to sleep enhancement
remedies. In an effort to be their best, many student-athletes
turn to over-the-counter supplements to help achieve
their goal of succeeding on the playing field. Over
the years, we have heard the stories of professional
athletes such as Matt Gugliotta, C.J. Hunter, Corey
Stringer, and Steve Belcher, whose lives were adversely
affected, or cut short, as a direct result of taking
sport supplements. The question is… do you know
everything there is to know about sport and nutritional
supplements?The Supplement Business is Big Business:
According to recent literature, approximately 40 percent
of Americans take supplements. Advertisements have convinced
many young people that they need to supplement their
diet, right or wrong! Phrases such as “No Pain,
No Gain”, “Bigger is Better”, and
“Bigger, Faster, Stronger” have created
a huge market for these supplements. Supplement companies
offer statements promising to increase muscle mass,
to burn fat quicker, to decrease recovery time after
workouts, and to prevent muscle cramps and fatigue.
The truth, however, is not always what is seems.
There are many anecdotal reports being marketed to the
general population by supplement companies on television
and in magazines regarding the success of their product.
In the scientific community, case evidence does not
hold weight against double blind research studies. Many
companies will try to make you believe that research
has been done. However, in most cases, these studies
are conducted by the same individuals trying to sell
you the supplement.
Misinformation About Supplements:
Where do most student-athletes get their information
regarding supplements? In most cases, it’s from
each other. Although there is a lot of information available,
not all of it is good information. This can often lead
to confusion among those taking these products. The
best place to get proper information is from an unbiased
source, based upon scientific facts to make intelligent
decisions.
There is a lot of misinformation being provided by various
sources. These sources include your friends, your mentors,
the internet, magazine ads, nutrition stores, and many
others. Keep in mind that many of these sources have
a vested interest in your decision. The best place to
get the information is from the professionals –
your Athletic Trainer is your best resource in finding
out what you need to know.
Long-Term Risks:
Because the supplement market is relatively young, researchers
are still trying to evaluate their long term effect
on the body. Most supplements have not yet been studied
over an extended period of time. In fact, most studies
conducted have only been sixteen weeks in length. Keep
in mind that twenty-five to thirty years ago, steroids
were thought to be okay. We can see now, only after
time, what long term effects have taken place.Safety
and Purity:
Safety and purity are major issues that need to be considered
in making intelligent decisions about sport supplements.
In 1994, federal legislation known as the Dietary Supplement
and Education Act was passed, thereby removing dietary
and nutritional supplements from FDA control. Since
then, manufacturers have been allowed to make claims
on their package labels or on ads without proof of safety
or efficacy. There are also no regulations that require
ingredient labels to accurately represent the contents
of their package. Recent studies demonstrated that ninety
percent of the supplements tested had contents in it
that were not on the label.

Appendix A
What Are Creatine and Androstenedione? Why Are Athletes
Using Them?
Creatine (cree-ah-ten) is a nitrogen-containing compound
found naturally in the body. About 95% of the body's
total creatine is found in skeletal muscle. Two-thirds
of the muscle's creatine is present in combination with
phosphorus. It is this creatine phosphate that plays
a critical role in the production of energy required
for muscular contraction in short term exercise (when
the demand for energy is greater than what can be supplied
by aerobic means). The concentration of creatine is
higher in fast twitch muscle fibers, which are better
suited to forceful, short-term contractions. The energy
production in short-term work appears to depend significantly
on the amount of creatine in the cell (or fiber). Thus,
the more creatine in the cell the greater the amount
of more forceful short-term work that can be done. Athletes
therefore may supplement their intake of creatine to
boost the muscle stores of creatine. This may allow
them to do more intense, short-term work, including
working longer before fatigue causes cessation of work.
Androstenedione (andro-steen-die-own, sometimes called
"andro" for short) is a steroid compound also
found naturally in the body. In the body androstenedione
is converted to the primary male sex hormone, testosterone,
as well as to the primary female sex hormones, estrogens
(estradiol and estrone). Plasma testosterone levels
are typically more than 10 times higher for the average
male than for the average female. Testosterone produces
male-like (or androgenic) effects. In addition to facial
hair and other masculine traits, testosterone may produce
larger muscles through an anabolic effect. On its own,
androstenedione has no muscle building effects. However,
it can raise the body's testosterone levels for at least
a few hours (possibly up to 24 hours). Whether this
short-term rise in testosterone levels is sufficient
to make any significant difference in muscle size, strength,
or speed of contraction is controversial. However, when
taken one-half hour to one hour before a workout, it
is likely to be sufficient to allow the athlete to train
harder and recover more quickly from exercise. An increase
in intensity and/or frequency of training could further
increase strength.
The primary reason athletes use creatine or androstenedione
is to increase overall strength and/or the ability to
do repetitive, intense, short-term work. Athletes in
sports where strength, sprint speed, or the ability
to do repeated and intense bouts of activity are the
most likely to use these substances. Some of these sports
might include football, hockey, and track and field
events like the shot put, discus, javelin, and shorter
sprints. Soccer and basketball players may also see
benefits to increasing their size, strength, and ability
to do repeated, intense, short-term bursts of activity.
Wrestlers may desire the increase in strength and ability
to do intense, short-term bouts of activity, but not
the increase in body mass. There are also some special
risks of using these substances when trying to lose
weight. Endurance sport athletes would probably benefit
little or be hampered by increased body mass or strength.
The added body mass could more than offset any increase
in intense, short-term efforts. Therefore, wrestlers
and those involved in endurance sports would probably
be less likely to use creatine. In addition to high
school athletes, those athletes involved in powerlifting,
bodybuilding, and martial arts may also use these substances.

Appendix BCreatine and Andro – What Are the Short
and Long-Term Risks?Creatine’s Short and Long-Term
Risks:
If the possible increase in muscle mass from creatine
use is due to an increase in water inside muscle cells
or fibers, this may cause dehydration to the rest of
the body. If dehydration occurs, and athletes are working
in conditions of high heat and humidity, heat stroke
and possibly death could result. These conditions of
high heat and humidity can result from rubber or plastic
suits, saunas, or superheated wrestling rooms. These
conditions are further exacerbated when athletes, such
as wrestlers, are trying to lose weight.
Nausea and stomach upset are short-term risks of creatine
use for some athletes. Concerns have been raised about
an increased occurrence of muscle cramping, sprains
and strains in those using creatine supplements.
Information about the risks of creatine supplementation
for more than one year is not available at this time.
There appear to be no well-controlled trials of this
length. Thus, one of the great risks of creatine supplementation
is that the long-term risks are unknown. Also, there
is the tendency of athletes to take more than the recommended
doses, believing that if the recommended dose is good,
more will be even better. Research is not available
on larger dosages of creatine.
Concerns have also been raised about possible long-term
or permanent suppression of the body's production of
creatine in the liver, pancreas, and kidneys. The higher
intake of creatine has been shown to suppress the synthesis
of creatine by the body.
These and other concerns prompted the NCAA Committee
on Competitive Safeguards and Medical Aspects of Sports
to recommend funding for research on the "physiological
effects of creatine other than performance." Grants
have been awarded for one year studies to the University
of Kansas, Pennsylvania State University and Georgia
Institute of Technology. The studies should be released
in August of 1999. Depending on the preliminary results,
longer studies may be planned. Stay in touch with the
NCAA to obtain the results of these studies. http://www.ncaa.orgAndrostenedione’s
Short and Long-Term Risks:
Few controlled studies on androstenedione are available.
One recent study, conducted at Iowa State University,
shows that the use of 300 milligrams of androstenedione
per day over an eight week period lowered the so-called
"good" cholesterol which protects against
heart disease. The supplement was also found to increase
blood serum estrogen, one of the female sex hormones.
(June 2. JAMA, 1999; 281:2020-2028c)
The synthesis of androstenedione into estrogens may
result in the enhancement of female characteristics
in both males and females (such as breast enlargement),
as well as other side effects such as an increased risk
of heart disease and pancreatic cancer.
The conclusion of these researchers was that "androstenedione
supplementation does not increase serum testosterone
concentrations or enhance skeletal muscle adaptations
to resistance training in normotestosterogenic young
men and may result in adverse health consequences."
Other researchers have noted that this study was conducted
on young men who were not already involved in weight
resistance training. The results may be different among
conditioned athletes, or at dosages larger than those
taken during the study.
Since androstenedione can be synthesized into testosterone,
one can probably assume that the short-term and long-term
risks are similar to other androgenic-anabolic steroids.
Anabolic-androgenic steroid use can affect the liver
and the cardiovascular system as well as the reproductive
system. Liver function can be damaged, resulting in
jaundice, blood-filled cysts, and tumors (including
those that are cancerous). Blood cholesterol levels
often increase because steroid use changes how sugars
and fats are handled. This and increased blood pressure
can lead to the early development of heart disease,
which can increase the risk of heart attacks and strokes.
For males, production of naturally occurring hormones,
like testosterone, may be decreased. This may result
in shrinking of the testes, low sperm counts, and infertility.
Because anabolic-androgenic steroids are derivative
of male hormones, female users may take on more male-like
characteristics, such as broader backs, wider shoulders,
thicker waists, flatter chests, more body and facial
hair and deeper voices. The clitoris may enlarge and
menstrual cycles may become irregular or stop. Steroids
may also affect muscles and other parts of the musculoskeletal
system. Tendons and ligaments may not strengthen at
the same rate the muscle tissue develops. As a result,
these tissues appear to be injured more often among
steroid users. Also, for adolescent athletes, steroid
use may cause the growth plates in long bones to close
faster than usual, which can result in lower height.
Oily skin and acne are also common among steroid users.
Some users experience dramatic mood swings. Anxiety,
irritability, aggressiveness, and impulsiveness may
occur.Evaluation by the Food and Drug Administration:
Most nutritional supplements have not been evaluated
by the Food and Drug Administration (FDA). Because creatine
and androstenedione have been categorized as nutritional
supplements, they have also not been closely evaluated.
Although the manufacturer of a nutritional supplement
must provide sufficient information (in FDA-specified
format) about the composition of the product, manufacturers
and distributors do not need to register with FDA or
get FDA approval. Thus, there can be a difference in
the composition of various creatine supplements. Some
investigations of supplements have shown that the actual
ingredients are not in the amount they claim to be.
One investigation found that the actual ingredients
in several supplements, including a creatine product,
deviated significantly more than 20% from what the product
actually claimed. The creatine supplement claimed to
contain 6.0 grams per serving. The test revealed 2.25
grams per serving.

as a banned substance. The rationale for this recommendation
is that research has shown EPHEDRA is a dangerous product
and should not be used in any form by adolescent-aged
student-athletes.
This recommendation was approved by the PIAA Board of
Directors at it's meeting of July 18, 2003. This is
effective immediately.
