DOPING
4
• Doping contravenes the fundamental principles of Olympism and sports and medical ethics.
• Doping is forbidden.
• Recommending, proposing, authorizing, condoning or facilitating the use of any substance or method covered by the definition of doping or trafficking therein is also forbidden.

Olympic Movement Anti-Doping Code - THE OFFENCE OF DOPING
Doping is:
1. the use of an expedient (substance or method) which is potentially harmful to athletes’ health and/or capable of enhancing their performance, or
2. the presence in the athlete’s body of a Prohibited Substance or evidence of the use thereof or evidence of the use of a Prohibited Method.

Drugs in Sport• 1886 - The first recorded death was in 1886
when a cyclist, Linton, died from an overdose of trimethyl.
• 1904 - The first near death in modern Olympics where a marathon runner, Thomas Hicks, was using a mixture of brandy and strychnine.
• Most drugs involved alcohol and strychnine. Heroin, caffeine and cocaine were also widely used until heroin and cocaine became available only on prescription.
7
Drugs in Sport• 1930s - Amphetamines were produced and
quickly became the choice over strychnine.
• 1950s - The Soviet team used male hormones to increase power and strength and the Americans developed steroids as a response.
• 1952 - One of the first noticeable doping cases involving amphetamines which occurred at the Winter Olympics. Several speed skaters became ill and needed medical attention.
8
Drugs in Sport• 1960 - At the Olympics, Danish cyclist, Kurt
Jensen, collapsed and died from an amphetamine overdose.
• 1963 - Pressure started to mount on the IOC. The Council of Europe set up a Committee on drugs but couldn't decide on a definition of doping.
• 1964 -There was a noticeable increase in the muscular appearance of the athletes at the Olympics and drug use was suspected.
9
Drugs in Sport• 1967 - The IOC took action after the death of
Tommy Simpson (due to the illegal taking of amphetamines) in the Tour de France.
• 1968 - The IOC decided on a definition of doping and developed a banned list of substances. Testing began at the Olympic games.
From the Australian Sports Drug Agency (ASDA) 1999
10
Drugs in Sport
• International Olympic Committee (IOC) produced first doping list in 1967
• Compulsory drug testing introduced in 1968– Winter Olympics - Grenoble– Summer Olympics - Mexico
• List of prohibited classes of substances and prohibited methods– defined by IOC (April 2000)

13
Prohibited Substances
• S1. Anabolic agents– 1. Anabolic Androgenic Steroids (AAS)
• a. Exogenous AASeg..nandrolone, 19-norandrostenedione, oxandrolone, stanozolol, and other substances with a similar chemical structure or similar biological effect(s)
• b. Endogenous AASeg. androstenediol, dehydroepiandrosterone (DHEA), dihydrotestosterone, testosterone
– 2. Other Anabolic Agents• eg. clenbuterol
14
Prohibited Substances
• S2. Peptide hormones, growth factors and related substances
– Includes1.erythropoiesis-stimulating agents [eg.erythropoietin (EPO)]
2.chorionic gonadotrophins and luteinizing hormone (LH) (males only)
3.corticotrophins (ACTH, tetracosactide)
4.growth hormone (hGH), insulin-like growth factor (IGF-1)…….
and other substances with similar chemical structure or similar biological effect
• S3. Beta-2 agonists– All are prohibited except salbutamol (max 1600ug over 24h),
formoterol (max delivered dose 54ug over 24 h) and salmeterol by inhalation
15
Drugs and Sport
• May of these drugs are illegal in both the eyes of the law and sport governing bodies
• Potentially serious medical risks– drugs are often taken at very high doses, considerably more than
is recommended– drug dependency
• Many of the drugs are expensive
• Many are bought on the black market– risk of drugs being mixed with other products– not purchasing the intended drug
16
Drugs and Sport - Why?
• Person– desire to be successful– lack of confidence– dissatisfaction with performance and progress– belief that others are using drugs– think they can get away with it– influenced by others– psychological dependence– lack of knowledge about side effects
17
Drugs and Sport - Why?• Environment
– culture of the sport– friends or other athletes using drugs – pressure to win (eg. from coach, friends, media)– influence of role models – financial reward– prestige and fame
• Pressure can appear from many directions– from self, coach, peers, family, spectators/crowd, media,
administrators/promoters, social, financial and material rewards, national/political/ideological
18
Drugs in Sport• Do they work?
– difficult to assess• difficult to recreate competitive situation in lab• fractions of a second or millimetres in length -difficult to
detect significant changes in laboratory experiments• most evidence anecdotal• placebo effect• environmental conditions
– effects may vary between individuals• males vs females• age of athlete
19
Drugs in Sport
• Do they work?– requirements of different sports will vary
• American footballer vs weightlifter
• sprinter vs marathon runner
– needs controlled scientific studies• limited number available
• conflicting results
• ethical problems– doses
20
Problems with drug testing
• Inconsistencies between countries– out of competition testing– length of ban
• Inconsistencies between sports federations– rules for testing– sanctions– status of doping agents– threshold levels
21
Difficulties with Testing• Endogenous substances
– what concentration is normal?– testosterone– human growth hormone (hGH)– erythropoietin (EPO)– athletes v general population
• Normal dietary intake– if people normally eat it can it be banned?
• caffeine, creatine
– does diet/exercise influence endogenous levels
22
Testing
• Methods of testing– urine, blood
• Blood testing issues– legal – ethical – procedural– medical
• Need for improved – rules?, – education – research– co-operation
between• governments• sports federations• governing bodies
23
Summary• Use of drugs in sport banned by IOC, International
and National Sport Federations/ Governing Bodies
• Drugs are potentially harmful to health and are considered to be ethically wrong
• Scientific evidence to support suggested beneficial performance effects of drugs is limited
• Further study required to assess both the suggested beneficial effects and the potential harmful effects
