Glossary

Welcome to the anti-doping glossary.

By clicking the links below you will be able to find out more about a number of commonly used anti-doping terms and phrases.

100% me

100% me is UK Anti-Doping’s athlete-centred education programme, which supports athletes to compete clean. It is a symbol for clean athletes to show their effort, commitment and determination to perform at the highest level, without a need to enhance performance through doping.

To find out more about 100% me, visit the Athlete Zone or follow us on Facebook.

ADAMS

The Anti-Doping Administration and Management System (ADAMS) enables athletes and anti-doping organisations to enter and share data related to doping control in order to meet their responsibilities under the World Anti-Doping Code (the Code). ADAMS is an online system which allows restricted sharing of data only with those organisations with a right to access such data in accordance with the Code. Athletes can access ADAMS via the website, using their unique login details.

Adverse Analytical Finding (AAF)

A doping control sample that shows the presence of a prohibited substance or its metabolites or markers (including elevated quantities of endogenous substances) or evidence of the use of a prohibited method following testing and its subsequent report. An adverse analytical finding does not necessarily lead to an anti-doping rule violation, since an athlete may have a Therapeutic Use Exemption (TUE) for this particular substance.

Altitude

Altitude is basically height and is used in anti-doping for the purposes of the Athlete Biological Passport. Altitude can affect an athlete’s blood variables e.g. red blood cell count. The World Health Organisation defines anything over 1000m as being at altitude.

Anabolic agent/steroid

Muscle-building chemicals - the synthetic derivatives of the naturally occurring male anabolic hormone testosterone. For further information on prohibited substances, please see the Prohibited List.

Anti-Doping Organisation (ADO)

An organisation responsible for adopting and executing rules for initiating, implementing or enforcing any part of the doping control process. This includes, for example, the International Olympic Committee, the International Paralympic Committee, other major event organisations that conduct testing at their events, the World Anti-Doping Agency, International Sports Federations, and National Anti-Doping Organisations.

Anti-Doping Rule Violation (ADRV)

Determination that one of the following rule violations listed in the Code has occurred:

  • The presence of a prohibited substance or its metabolites or markers in an athlete’s sample
  • Use or attempted use by an athlete of a prohibited substance or a prohibited method
  • Evading, refusing, or failing to submit to sample collection
  • Whereabouts failures: any combination of three missed tests and/or filing failures within a 12-month period by an athlete in a registered testing pool
  • Tampering or attempted tampering with any part of doping control
  • Possession of a prohibited substance or prohibited method
  • Trafficking or attempted trafficking in any prohibited substance or prohibited method
  • Administration or attempted administration to any athlete in-competition of any prohibited method or prohibited substance, or administration or attempted administration to any athlete out-of-competition of any prohibited method or any prohibited substance that is prohibited out-of-competition
  • Complicity: assisting, encouraging, aiding, abetting, conspiring, covering up or any other type of intentional complicity involving an ADRV or any attempted ADRV
  • Prohibited Association: associating with a person such as a coach, doctor or physio who has been found guilty of a criminal or disciplinary offence equivalent to a doping violation

Athlete Biological Passport (ABP)

The concept of an athlete biological passport (ABP) is the monitoring of selected biomarkers which indirectly reveal the effects of doping, as opposed to the traditional testing model.  Biological tracing throughout an athlete’s sporting career should make doping far harder to achieve undetected.

An ABP comprises a longitudinal series of tests collected from an athlete which enables individual limits for each biomarker to be established.  The concept of the ABP is that it switches the focus from comparison with the population (i.e. all athletes), to the creation of individual reference ranges. The baseline target for new athletes on the programme is 6 samples over a 12 month period.

Athlete Support Personnel

Any coach, trainer, manager, agent, team staff member, official, medical or paramedical personnel, parent or any other person working to treat or assist an athlete participating in or preparing for sports competition.

Visit the Support Personnel section of the website.

Athlete Whereabouts

Information provided by or on behalf of an athlete detailing the athlete’s location on a daily basis in order to enable unannounced testing.

Beta-2 agonists

Beta-2 agonists are a group of medications primarily used to treat asthma. They act on smooth muscle to relax the muscles (and therefore in the case of asthma, dilation of the airways).

Beta-blockers

Beta-blockers block the signal transmission through the beta-receptors in the body. These receptors occur on cells in various parts of the body including the heart, brain, and blood vessels. Beta-blockers prevent the actions of adrenaline and noradrenaline. In doing so, Beta-blockers can reduce the heart rate and reduce the force at which the heart contracts. This results in a drop in blood pressure and less work for the heart.

Athletes may use Beta-blockers to decrease their heart rate, steady nerves, reduce anxiety and stop trembling.  This will be of particular advantage in sports requiring a high degree of accuracy.

The side-effects of Beta-blockers depend on which one is being taken. Some common side-effects are: cold hands and feet, tiredness, headaches, dizziness, too low heart rate and wheezing.

For further information on prohibited substances, please see the Prohibited List.

Blood Collection Officer (BCO)

Court of Arbitration for Sport (CAS)

The CAS is independent of any sports organisation and provides services to facilitate the settlement of sport-related disputes through arbitration or mediation by means of procedural rules adapted to the specific needs of the sports world.

The CAS is often referred to as “sport’s supreme court.” WADA has a right of appeal to CAS for doping cases under the jurisdiction of organisations that have implemented the World Anti-Doping Code.

Visit the CAS website.

Diuretics

Diuretics promote the excretion of fluid from the body by increasing the production of urine.  They increase water and electrolyte excretion by the kidneys. They are used in the treatment of heart failure, high blood pressure and diseases of the kidney and liver.

Doping Control

The process that includes test distribution planning, sample collection and handling, laboratory analysis, Therapeutic Use Exemptions (TUEs), results management, hearings and appeals.

Doping Control Officer (DCO)

Doping Control Station

Location where the sample collection session is conducted. For example, this may be a changing room at a sports venue.

Erythropoietin (EPO)

The human body naturally produces a substance called erythropoietin (“EPO”). EPO is a peptide hormone secreted primarily from the kidney which stimulates the production of red blood cells from the bone marrow. This process is called erythropoiesis. Red blood cells are responsible for oxygen transportation within the body. EPO is also manufactured artificially for use in medical treatment.

Gene Doping

The following, with the potential to enhance sport performance, are prohibited:

  1. The transfer of nucleic acids or nucleic acid sequences;
  2. The use of normal or genetically modified cells;
  3. The use of agents that directly or indirectly affect functions known to influence performance by altering gene expression.

Haematological Profiling

The longitudinal assessment of an athlete’s blood variables e.g. haemoglobin or reticulocytes.

Human Growth Hormone

Anabolic hormone that occurs naturally in the human body. It is produced by the pituitary gland in the brain and stimulates the growth of muscle, cartilage, and bone. Excess hGH in the body can cause acromegaly, a disease where the hands become spade-like in appearance as they get bigger. Growth of the facial bones causes the face to change shape too.

For further information on prohibited substances, please see the Prohibited List.

In- and Out-of-Competition

The ‘in-competition’ period usually begins twelve hours before a competition the athlete is participating in and finishes at the end of any associated doping control.

‘Out-of-competition’ is regarded as any other time.

In-and out-of-competition period may be different during major events such as from when the Athletes' Village opens.

Results Management

Process for the pre-hearing administration of potential anti-doping rule violations. This process notably includes the initial review of the adverse analytical finding (determination of whether an applicable therapeutic use exemption has been granted, notification of the athlete as regards his or her right to request the B-sample analysis) and the possible imposition of a provisional suspension.

WADA is never involved in the individual management of findings, which falls under the responsibility of the anti-doping organisation involved in the particular case.

More information on Results Management.

Reticulocytes

An early, immature form of a red blood cell. Over time, the reticulocyte develops to become a mature, oxygen-carrying red blood cell.

Sample/Specimen

Sample Collection

All of the sequential activities that directly involve the athlete, from notification until the athlete leaves the doping control station after having provided his/her sample/s.

Specified Substance

Specified substances are those that, if found to be present in an athlete’s bodily sample, may be more likely to have a credible, non-doping explanation.

View the Prohibited List.

Stimulants

Stimulants act on the brain to increase alertness and physical activity stimulating the body both mentally and physically. They act on the central and/or peripheral nervous system to increase heart rate, breathing rate, and brain function. Some stimulants affect only a specific organ, such as the heart, lungs or brain and some are highly addictive.

Strict Liability

The principle of strict liability means that an anti-doping rule violation occurs whenever a prohibited substance (or its metabolites or markers) is found in the bodily specimen of an athlete, whether or not the athlete intentionally or unintentionally used a prohibited substance or was negligent or otherwise at fault.

Find out more about what happens when a sample is found to be positive.

Supplements

Although there is no official definition, supplements might be regarded as products
used to enhance the levels of nutrients in the body, in addition to those obtained from the diet.
