Better Drugs, Better Athletes
Better
drugs, better athletes? Stay tuned. This is Dr. Steven Andrew Davis, Speaking of
Health. The Olympic Games are right
around the corner, and so are the headlines and stories about performance
enhancing drugs. Who’s taking what; who
got disqualified; what medals were taken away?
This
is not even a predictable sub-plot – it’s part of the main plot now. While heading the list of
performance-enhancing drugs are anabolic-androgenic steroids, other drugs can
influence performance too. And they are
not steroids; and it can be hard to detect some of them.
In
timely fashion, The Medical Letter on
Drugs and Therapeutics reviewed the various performance-enhancing
drugs. Some are stimulants, so-called
“sympathomimetic amines and other central-nervous system stimulants” which
foster weight loss and increased energy, speed and endurance. Unfortunately, these drugs, and dietary
supplements which contain them, can also cause dangerous high blood pressure,
seizures, strokes, heart attacks, heat stroke and psychosis.
Other
drugs have virtually the opposite impact on athletes, some of who have resorted
to using beta-blockers – time-honored blood pressure medicines – to slow their
heart rates and reduce nervousness or tremor.
Various non-steroid hormones are also abused by the inspiring
athlete. Human growth hormone has some
anabolic, or muscle building effects, but can cause muscle, joint and cardiac
problems. Even insulin – the diabetes
wonder-drug, has been used by body-builders to inhibit muscle breakdown. Insulin, though, can seriously backfire when
overdosed.
