Understanding Doping in Athletics


Some sportspeople try to gain an advantage by using performance-enhancing drugs. This is known as doping. Many performance-enhancing drugs are banned by nearly all sports’ governing bodies, athletic bodies included.doping

Performance enhancing drugs are mostly used to improve athletic abilities and give an unfair advantage over competitors in sports. Bodies like the World Anti-Doping Agency and the International Olympic Committee banned performance enhancing drugs but because of the severe competition to be the best, the use of performance enhancing drugs in sports has become increasingly common.

Types of Drugs

Body modification

There are several types of drug that an athlete can use to enhance his or her performance.

Some of these drugs are banned by law and some are legally available on prescription, but they are all prohibited by sporting regulations. (When we use the word ‘illegal’, we mean it in this sense.)

Drugs that boost bodily functions, including heart rate and brain activity.
Examples: cocaine, adrafinil

Anabolic steroids
This category of steroids stimulates muscle growth and can allow athletes to train harder and recover more quickly. They work like testosterone, meaning that they can cause a deepened voice and increased body hair in female athletes.
Some athletes take normal testosterone instead, which has the same effect. Though testosterone is a natural hormone, illegal use of it can be detected.
Examples: drostanolone, tetrahydrogestrinone (THG)

Painkillers used to control pain from injuries or allow athletes to train for longer. If they are being used in order to ignore an injury, athletes obviously risk doing further damage.
Examples: morphine, heroin

Peptide hormones
Naturally-occurring substances that circulate in the blood, and can improve muscle growth, change the balance of other hormones and increase production of red blood cells, which increases oxygen delivery.
Examples: insulin, human growth hormone

Beta2 agonists
The kind of drug found in asthma inhalers. As in the treatment of asthma, when inhaled they relax the airways, allowing more oxygen to reach the blood. If injected, they are thought to have effects similar to those of anabolic steroids, but this does not appear to have been proven.
Examples: salbutamol, terbutalene

Not performance-enhancing drugs on their own, but used to get rid of the traces of other drugs.
Diuretics increase the production of urine, and some athletes use them to try to flush out residue from steroids. They can also be used to shed water as a temporary weight loss measure in sports with weight categories (boxing, equestrian sports).
There are several categories of diuretic drugs. Naturally-occurring diuretics include alcohol and caffeine.

Blood Doping

The name of this process is slightly misleading: it should not be confused with ‘doping’ in general. Blood doping may or may not involve a drug. It is the process of artificially increasing the concentration of red blood cells in the blood. More red cells result in more oxygenated blood reaching the muscles.

The red blood cell level, as a percentage of the blood, is called haematocrit. In men the normal haematocrit range is 40-54 per cent, and in women it is 37-47 per cent. In cycling, a sport prone to blood doping, authorities now test haematocrit levels and ban those above 50%. Athletes with naturally high levels must prove it by being tested over several months.

There are two main methods of blood doping. An athlete could inject extra red cells, either from a donor or previously harvested from the athlete’s own blood, or take a drug to boost their production.

A blood transfusion is dangerous to attempt during a competition because of the difficulty of smuggling in frozen blood and (sometimes unsterilised) medical equipment and using them unsupervised.

The drug most commonly used to boost red cell production is erythropoietin. Erythropoietin can cause heart attacks or blood clotting if used excessively, and may also damage the immune system (the white blood cells).

Who regulates drugs in Athletics?

WADA, the World Anti-Doping Agency, is an independent body formed by the International Olympic Committee in 1999 with the responsibility of fighting drug-taking in sport and ensuring impartiality and rigour in drug testing. It’s WADA that maintains the list of banned substances. It also conducts drug testing, provides assistance to countries’ own anti-doping programmes, and funds research.

The World Anti-Doping Code was introduced in 2004 to coincide with the Olympic Games in Athens. The Code standardises the rules and regulations governing doping across all organised sports.

Countries that follow the Code have their own regulatory bodies. In Kenya, anti-doping measures are controlled by the government, through the Ministry of Sports.


The synthetic steroid THG (tetrahydrogestrinone) came to prominence in the summer of 2004 after one coach ‘blew the whistle’. He sent a sample of the drug to the United States Anti-Doping Agency, exposing its use.

THG had never been spotted before because it was a new synthetic drug, designed to be undetectable. With a sample, though, the Anti-Doping Agency was able to develop a test for the drug – and many prominent sports players and athletes were engulfed in the subsequent scandal.

The whistle-blowing coach in question is called Trevor Graham. In an interview he said: “As a coach it seemed the right thing to do at the time and it still does.”

Is it the right thing to report a fellow competitor for cheating? If you are not cheating yourself, then it could be considered reasonable to report someone who is.

Because it is obviously in a competitor’s interests to disqualify a rival, authorities have to take the source of the accusations into account.
