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 (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 which 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 for this particular substance.
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 bodily specimen
- Use or attempted use of a prohibited substance or a prohibited method
- Refusing, or failing without compelling justification, to submit to sample collection after notification, as authorised in applicable anti-doping rules or otherwise evading sample collection
- Violation of applicable requirements regarding athlete availability for out-of-competition testing, including failure to provide whereabouts information and missed tests which are declared based on reasonable rules
- Tampering, or attempting to tamper, with any part of doping control
- Possession of prohibited substances and methods
- Trafficking in any prohibited substance or prohibited method
- Administration or attempted administration of a prohibited substance or prohibited method to any athlete, or assisting, encouraging, aiding, abetting, covering up or any other type of complicity involving an anti-doping rule violation or any attempted violation.
Athlete Biological Passport/Blood Profiling
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.

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-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.

Registered Testing Pool
Pool of elite level athletes, established by each International Federation (IF) and National Anti-Doping Organisation (NADO), who are subject to both in-competition and out-of-competition testing as part of that IF’s or NADO’s test distribution plan.
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.
