Performance Enhancing
Substances
Psychology
The Ideal Performance State
Absence of fear—no fear of failure
No thinking about or analysis of performance
Narrow focus of attention concentrated on the
activity itself
Sense of effortlessness—an involuntary experience
Sense of personal control
Distortion of time and space
Relationship
Between
Confidence
and Athletic
Performance
Why Goal Setting Affects Performance
Goals direct athlete’s attention by prioritizing efforts.
Goals increase effort because of the contingency of
success on goal attainment.
Goals increase positive reinforcement through
feedback given to athletes.

Enhancing Substances
Types of Performance-Enhancing
Substances
Naturally occurring hormones and the drugs that
mimic their effects
Dietary supplements
Definition of Products That Can Be
Sold as Dietary Supplements
A product (other than tobacco) intended to
supplement the diet. The product contains one or
more of the following: vitamin; mineral; herb or other
botanical; amino acid; dietary substance for use by
humans; or a concentrate, metabolite, constituent,
extract, or combination of these ingredients.
The product must also be intended for ingestion and
cannot be advertised for use as a food.

Body Composition Changes With Anabolic Steroids
Risks of Anabolic Steroid Use
Primary risk for women is masculinization.
Primary risks for young boys are accelerated
puberty; early closure of the ends of the long bones.
Both males and females who use high doses of
anabolic steroids are at risk for psychological
changes that include increased aggressiveness.
Potential Risks to Performance
Uncontrolled emotional responses directed at a
teammate
Unanticipated decline in performance when steroid
use is stopped
Undesirable increase in body weight in aerobic
endurance athletes
Anabolic Steroids: Bottom Lines
Anabolic steroid use will likely increase body
weight.
Other performance benefits have not been well tested
or demonstrated.
Suspected psychological effects are difficult to test.
Health risks in men are comparable to known risks
to women from use of oral steroidal contraceptives.
More serious health risks accompany the use of
very high doses of anabolic steroids.
Other Hormones Used by Athletes
As Ergogenic Aids
Human chorionic gonadotropin increases testicular
testosterone production.
Growth hormone stimulates physical growth of the
body.
Erythropoietin stimulates red blood cell production.
Beta-adrenergic agonists affect the metabolic and
nervous systems.
Problems in Drug Testing
Some ergogenic substances, such as caffeine,
occur naturally in the body.
Some substances, such as recombinant human
growth hormone, are difficult to test for because
they are indistinguishable from naturally occurring
hormones.
Masking agents may dilute the urine specimen and
make it difficult to obtain a positive test.
