This document discusses various topics related to doping in sports, including:
- Definitions of doping and performance-enhancing substances
- Types of doping methods like use of therapeutic drugs, blood doping, and stimulants
- Health risks of doping practices like steroids and blood doping
- Establishment of organizations like WADA to regulate anti-doping efforts
- Prevalence of doping among athletes and reasons some feel they need performance enhancers
In competitive sports, doping is the use of banned athletic performance-enhancing drugs by athletic competitors. The term doping is widely used by organizations that regulate sporting competitions. The use of drugs to enhance performance is considered unethical, and therefore prohibited, by most international sports organizations, including the International Olympic Committee. Furthermore, athletes (or athletic programs) taking explicit measures to evade detection exacerbate the ethical violation with overt deception and cheating.

Role of Physiotherapist in Doping Controldrnidhimnd
Doping is the ‘administration of or use by a
competing athlete of any substance foreign to
the body or any physiological substance taken
in abnormal quantity or taken by an abnormal
route of entry into the body with the sole
purpose of increasing in an artificial and unfair
manner his / her performance in competition.’
Impact of anabolic steroids & other appearance & performance enhancing drugs ...MD Hammad Choudhary
Anabolic steroids are synthetic, or human-made variations of the male sex hormone testosterone. The proper term of these compounds is anabolic-androgenic steroids (AAS). These are the most popularly used class of Appearance & Performance enhancing drugs (APEDs) hence called steroidal APEDs.

Understanding Performance-Enhancing Drug Use
DAVID WANG MD, MS
ABSTRACT—Performance-enhancing drug use
is a prevalent problem in sports. It is a problem
that has captured the world's attention as the media
highlights story after story of athletes who have
transformed their bodies over a short period of time,
those who have simply defíed the aging process in
an attempt to prolong a career and those whose ca-
reers have been tarnished because of drug use. The
baseball investigations and the Mitchell Report*
of 2007 opened our eyes and gave us a glimpse of a
secretive underground world. This "world" is much
more intelligent and sophisticated than it is given
credit for. It is the goal of this article to increase the
awareness of the medical provider about the types of
steroids and other medications used, the influence
these substances have on the athletes, and how and
why they use them.

RUG use is an area in sports medicine that is crucial
to recognize and is poorly studied, largely because
the use of performance-enhancing substances
are illegal and therefore rarely, if ever, reported. It is an
area difficult to gather scientific data about, but with the
severity of consequences from the use of these substances
it is imperative that the prudent practitioner is familiar
enough with the substances and practices that red flags
would be recognized and an open and honest discussion
with the patient on the wrong path could occur.
During the course of a 20-year practice of sports medi-
cine and I have encountered the use of these substances
by athletes of all sorts. I have spent time in a smaller
gym populated by serious bodybuilders and witnessed
practices most would not know existed. Through con-
versations with these bodybuilders, and I have learned of
the countless steroids that are "stacked" and the myriad
of other medications used to achieve their desired results
or to manage side effects. The medical community is well
aware of the existence of anabolic-androgenic steroids
and human growth hormone ( H G H ) and their use for
performance enhancement. However, most practitioners
are often not well versed on the specific types of steroids
and other medications that are used in combination with
these ergogenic aids. It is the "other" medications that
are responsible for much of the morbidity and mortal-
ity within this population. When these athletes die it
is often due to narcotic addiction and, to a much lesser
degree, anabolic steroids and growth hormone use. Al-
though the exact number of deaths is unknown, I have
seen and heard of several. In my experience and I have
witnessed or cared for several tragic deaths in training
and competition. The number of deaths witnessed from
drug use equals those observed from congenital heart
disease and head injury.

It is derived from the Dutch word "dop", a
beverage that Zulu soldiers used before
battles.
The term is used at 20th century in
reference to illegal drugging of racehorses
It is derived from "dop" an alcoholic drink
used as a stimulant in ceremonial dances
in Southern Africa.

Egyptian slaves fed elixirs (likely from khat
leaves) to relieve stress
Greek athletes ate energy boosting
substances prior to activity
A century ago, marathoners used
strychnine, and cyclists used caffeine,
cocaine, and even alcohol for an advantage.
The first reported death occurred in 1896
when an English cyclist died of an overdose

Doping means use of substances which
enhance performance. These substances
may be natural, synthetic, drugs or blood.
The definition of doping established by
the International Olympic Committee
IOC is based on the prohibition of certain
types of pharmaceuticals.
10. What is a Performance-Enhancing
Substance (PES) ?
“...any substance taken in non-pharmacologic
doses specifically for the
purposes of improving sports performance,
- by increasing strength, power, speed, or
endurance
- or by altering body weight or body
composition.”
11. Why some aatthhlleetteess nneeeedd ddooppiinngg ??
Some athletes do anything to win
Belief that competitors take drugs
Financial rewards

14. DDooppiinngg aanndd hheeaalltthh pprroobblleemmss
Direct relationship between certain drugs
and certain health problems
Several doping substances lead to drug
abuse and dependence.
Some drugs have psychological effects
and lead to changes in the behavior.
15. DDooppiinngg aanndd hheeaalltthh pprroobblleemmss
Caffeine intoxication can lead to
nervousness, overexcitement, insomnia, or
attacks of anxiety in certain persons.
Cocaine or amphetamine intoxication can
cause hyperactivity, anxiety, anger, altered
judgment and violent behavior.
Their chronic use can cause dulled
emotions, fatigue, sadness, social
withdrawal, mania and aggressiveness.
16. DDooppiinngg aanndd hheeaalltthh pprroobblleemmss
Dangerous drug cocktails can be
made up of different drugs, or of similar
drugs with different names.
Drug cocktails bring the dosage to
toxic levels e.g. amphetamines
combined with corticoids, cocaine,
caffeine or ephedrin; EPO combined
with aspirin; a combination of
androgens and GH.
23. Anabolic Androgenic
Steroids (AAS)
AAS are a class of steroid hormones
related to the hormone testosterone.
Testosterone affects nearly every
system and tissue in the human body.

Recombinant erythropoietin (rEPO)
is a genetically engineered substance
similar to erythropoietin.
(rEPO) is used in treatment of
anemia of chronic end-stage renal
disease and other forms of anemia.
Athletes use (rEPO) instead of blood
transfusion to RBCs formation.
