Genetic based doping and new drugs used by athletes
Can doping by Olympic athletes be stopped
Don Catlin, the laboratory's director, said that the detection of
EPO and HGH abuse is quite difficult because they appear only in very
very small quantities in body fluids. EPO increases oxygen uptake to the working
muscles, and HGH improves muscle growth.
When extracting EPO from urine,
Catlin says, "the less there is of it, the harder it is to extract
with good recovery." He also says, "A lot of the drugs we are dealing with have
molecular weights of 300. EPO has a molecular weight of 30,000 to 35,000, which is too
big for our mass spectrometers to work on." In response, the WADA has included methods such as gene and blood doping
to its list of banned or prohibited substances. New testing methods are
being developed all the time to increase detection of "gene" manipulation
and blood tests, rather than urine testing, is already on its way to
becoming the standard for detecting prohibited drug users. |

| Even in the face of these new challenges, research scientists are very confident that they will able to detect these new substances and their delivery methods. Researchers are developing more effective testing methods, streamlining existing detection procedures, and working with drug detection agencies such as the WADA to ensure that Twenty First century technology benefits, rather than compromises, the spirit of the ancient Olympics. |

The toxicology report on Baltimore Orioles pitching prospect Steve Bechler released today implicates the use of the herbal supplement ephedra in his death, and underscores once more the dangers of ephedra use, particularly when combined with other risk factors.
Although they may build muscle, steroids can produce very serious side effects in both males and females. Using steroids for a long period of time can negatively affect the reproductive systems.
Wadler, who is attending the ACSM Annual Meeting in St. Louis this week, said that the subject of steroid use in baseball peaked in 1998, when Mark McGwire admitted to the use of the testosterone precursor, androstenedione.
An athletic boost in the short term may mean health problems in the long term for teens who use performance-enhancing drugs, warns a youth sports medicine specialist from the University of Michigan Health System.
The University of Georgia has issued a statement that responds to the announcement by the NCAA of sanctions that it has imposed on the university as a result of its investigation of the school's men's basketball program.

"We are not sure why women's testosterone elevation prior to competition is so much greater than it is in men. It is probably due to the fact that every day levels of testosterone are four times higher in men than they are in women.
Proposed a warning label for all ephedra-containing dietary supplements. The proposed label warns about the risks of serious adverse events, including seizure, heart attack, stroke, and even death.
Early amateur scullers and oarsmen were also often boxers, with some rowing clubs also including boxing sections. Rowing was introduced at Oxford University in the late 1700s and in 1806 the sport of rowing was also introduced at Eton College.
The Department of Health and Human Services (HHS) has made an announcement that a series of actions aimed at protecting US citizens from the potential grave risks associated with dietary supplements that contain ephedra.
Many physicians feel that some dietary supplements' should be considered drugs' because they contain known active ingredients, whereas dietary supplements' have little or no physiologic effects.
It's definitely possible to be overweight and fit, but it does depend on the level of fitness that you're talking about. Even if someone is overweight, they can achieve multiple benefits by starting an exercise program.
