Scientific research on doping
Pr. Segura, a leading authority in anti-doping research, speaks about his work.
According to the expert -Pr Segura- scientific research on doping mostly focuses on inventing new methods to reliably detect prohibited substances the athletes may have used. More specifically Pr Segura explains:

- Could you tell us some things about your research and any important results if there are?
- Our research is focused in doping substances and some new technologies to detect them and is also focused in the analysis of drugs of abuse, in general.
- What do experts consider as doping since there seems to be a confusion?
- According to the "Olympic Movement Anti-doping Code, Chapter II, Article 2" doping is:
- the use of an expedient (substance or method) which is potentially harmful to athletes' health and/or capable of enhancing their performance, or
- the presence in the athletes' body of a Prohibited Substance or evidence of the use there of or evidence of the use of a Prohibited Method.
- What are the most usual substances that are used for doping?
- Below is a table including the number of substances identified in the banned classes (IOC Statistics 1998):
|C. Anabolic Agents||856||39.3|
|A/C. Beta Agonist||479||22.0|
|D. Beta Blockers||12||0.6|
|F. Masking Agents||16||0.7|
|G. Peptide Hormones||12||0.6|
- How much difficult the "detection" of these substances is?
- Peptide hormones are the most difficult substances to detect due to the difficulty to distinguish between the endogenous and exogenous hormone.
- What negative effects can these chemicals have long-termly?
- There are many and they depend on the substance used each time. Morphine and other compounds of this class have major side effects including respiratory depression and they carry a risk of physical and psychological dependence. Amphetamine and related compounds have the most notorious reputation in producing problems in sport. Some deaths of sportsmen have resulted even when normal doses have been used under conditions of maximum physical stress. Another example is growth hormone which causes many adverse effects like cardiomiopathy, hypertention, diabetes mellitus when given in high doses for a long period of time. Please see http://www.nodoping.org/(IOC web page) for an in-depth description for each substance.
- Do you think the fame that athletes have as a result for their success worths the damage to their health caused by doping?
