New
studies shed light on nandrolone
This article is
being written at the IAAF World Championships in Athletics in Edmonton,
where the drug talk is all about the blood-boosting hormone EPO (erythropoietin).
For the first time, the IAAF will introduce blood tests at this World
Championships. Of the 350 doping tests being conducted here, 15 to 20
percent will test for EPO in an elaborate double positive system whereby
an athlete must test positive in both urine and blood samples to incur
a doping offense.
Meanwhile, controversies
over the anabolic steroid nandrolone continue. In 1999, IOC-accredited
labs worldwide detected 343 positive nandrolone findings, up from 259
the previous year. In the United Kingdom, nandrolone findings jumped
sharply from four positives in 1998 to 17 in 1999. In Canada we have
seen a growing number of nandrolone positives in the last four years,
including two this summer alone. Three Canadian cases involving the
steroid are presently in the process of adjudication.
On their own, these
figures are not cause for grave concern. What has been alarming, however,
is the sharp increase in the number of positive tests among big name
athletes - the likes of Peter Korda, Merlene Ottey, Linford Christie,
Doug Walker, Gary Cadogan, Dieter Baumann and Mark Richardson.
The revelation during the Sydney Olympics that American shot putter
C.J. Hunter, then-husband of sprinter Marion Jones, had tested positive
four times in the year 2000 put the steroid nandrolone on the front
page of newspapers around the world.
The recent so-called
"rash" of nandrolone positive tests is odd, given that this
close chemical cousin of testosterone has existed for a long time and
is very easily detected. In other words, why would prominent and frequently
tested athletes even consider using it? Observers point to two factors
to explain this increase in positive tests: one, the steroid has recently
become available in pill form and is more easily ingested and more quickly
cleared from the system, thus increasing its usage by athletes; and
two, the adverse findings may be the result of contaminated nutritional
supplements.
This latter claim
has resulted in the commissioning of at least three studies into the
nandrolone situation. One of these studies was a general literature
review by a panel of 35 British experts while the other two were laboratory-based
studies exposing volunteer subjects to nutritional supplements to determine
if these supplements could produce nandrolone metabolites.
The nandrolone review
was commissioned by the U.K. Sports Council and was released in January
2000. It concluded that:
- The sample collection
and laboratory analysis procedures recommended by the IOC for testing
for nandrolone were satisfactory;
- Some dietary
supplements may contain compounds similar to nandrolone or its metabolic
precursors and these are not always included in the product labeling;
- Athletes are
advised to steer clear of eating the offal of boar and horse, as these
foods were known to contain low levels of nandrolone; and
- There existed
no evidence to suggest that dietary substances could influence the
production of nandrolone in the body.
The study properly
concluded that the sports community must maintain a high level of awareness
of the hazards of nutritional supplements and herbal products, and that
further research should be carried out on the factors that influence
the endogenous production of nandrolone in humans.
The two other studies
were carried out at the University of Aberdeen under Professor Ron
Maughan (a world-recognized expert on sports drinks) and at the
IOC-accredited laboratory in Cologne under the supervision of Dr.
Wilhelm Schänzer of the German Sports University. The first
study was partially funded by the IAAF and the latter study by the IOC.
In the Aberdeen
study Professor Maughan concluded that athletes taking dietary supplements
that did not contain prohibited substances "could when combined
with vigorous exercise, stress and dehydration, result in production
of higher concentrations of nandrolone metabolites in the athlete's
bodily fluids".
In the Cologne study,
it is reported that Dr. Schänzer found that of 100 common nutritional
supplements purchased in Europe and the U.K., 16 were contaminated and
three led to adverse findings for nandrolone in volunteer subjects.
Dr. Schänzer has said he intends to test 600 more commonly available
nutritional products.
It was in part on
the strength of the results of the Cologne study, released in the spring
of 2001, that U.K. 400-metres runner Mark Richardson was reinstated
by the IAAF in June of this year, enabling him to compete at the 2001
World Championships. On the other hand, the University of Aberdeen study
was discounted by an IAAF arbitration panel for a variety of scientific
reasons, including the fact that Professor Maughan was not independent
as he subsequently was part of the U.K. Athletics disciplinary committee
that considered favourably the cases of Christie, Walker and Cadogan.
Upon the release
of the Cologne study results, David Moorcroft, CEO of U.K. Athletics
stated: "in terms of guilt or innocence it doesn't change a great
deal, because the athlete is still responsible for what's in his body.
But it does put the degree of guilt in some form of context".
Upon his reinstatement,
Mark Richardson stated to fellow athletes and the public: "My advice
is simple - don't take supplements. Until the supplement industry is
regulated, then it's a lottery as to what is in the supplement".
These are wise comments
from both men. The results of the Cologne study might suggest "reasonable
doubt" as to whether athletes exhibiting low concentrations of
nandrolone actually cheated. However, the "strict liability"
basis of the IAAF and Canadian doping control programs do not accommodate
"reasonable doubt" or even "a balance of probabilities".
The presence in the body of a banned substance, or the presence in the
body of a naturally occurring substance at levels deemed to be banned,
is a doping offense, period. Accidental ingestion or intent to cheat
are irrelevant considerations.
This notion of strict
liability can be explained to the layperson in terms of commonly understood
drinking and driving laws. In Canada, it is a criminal offense to operate
a motor vehicle with a blood-alcohol level exceeding .08. At this level
some individuals will be roaring drunk while others will be mildly impaired
- the threshold does not take into account such differences from one
person to the next. As well, the law doesn't care how the alcohol entered
the bloodstream - even if it was forced down the driver's throat or
introduced into the body through intravenous while the driver was asleep
- its presence there above the level of .08 is against the rules.
In sport, it is
against the rules to have more than 2 ng/ml (for a man) or 5 ng/ml (for
a woman) of nandrolone metabolites in one's urine. The mere presence
of such metabolites above these levels is a doping offense. This is
true whether the levels are low (such as they were for Canadians Robin
Lyons, Theresa Brick and Carolyne Lepage) or astronomically high
(such as they were for Linford Christie and C.J. Hunter, who recorded
one hundred and one thousand times the legal limit, respectively).
For these reasons,
the adjudicators who are presently hearing and deciding three of Canada's
nandrolone cases face a difficult task. Any one of the athletes appearing
before them might present a convincing case that their nandrolone consumption
was inadvertent, and it doesn't make a bit of difference. Intent to
cheat, an otherwise clean history, credibility and compassion are not
part of the equation
but perhaps they should be.
In doping, as in
sport, the rules are the rules. When the IAAF declined to reinstate
Linford Christie, Doug Walker and Gary Cadogan it stated in its August
2000 Newsletter that the decision was not made to defend the current
system, "it was made to respect and apply the current rules".
Nandrolone
is a banned substance under the IOC Anti-Doping Code when it
is found at levels exceeding 2 ng/ml in men and 5 ng/ml in women.
Unlike most banned steroids, nandrolone occurs naturally in
the human body. In a 1999 study, it was found that approximately
half of the test subjects produced nandrolone metabolites at
trace levels (on average, .6 ng/ml). It is also known that women
produce higher levels of nandrolone metabolites than men.

Until those rules
are changed, the nandrolone issue will remain difficult and controversial.
The rules say where the blue line is on a hockey surface and if we don't
like the resulting offside call there's not much we can do about it
unless we're prepared to move the blue line. The IOC hasn't moved on
nandrolone and unless and until it does, the IAAF as well as domestic
doping control and adjudication systems must respect the rules.
For athletes, the
clear lesson in this is to heed Mark Richardson's advice and avoid nutritional
supplements. With proper sports nutrition, they aren't necessary for
athletic performance. The supplement industry is unregulated and the
consumer of these products has no assurances as to what's in the bottle
or package - either because labeling is inaccurate, or because the supplement
has been contaminated during the manufacturing process.
In the last 18 months,
the Canadian Centre for Ethics in Sport has issued no fewer than five
Advisory Notes cautioning athletes about nutritional supplements. Despite
these frequent cautions, high performance athletes continue to consume
nutritional products in alarming amounts and combinations. It has been
suggested (but by no means scientifically proven) that such "cocktails"
of legal nutritional supplements combined with vigorous exercise may
produce illegal results.
As we have stated
before in the pages of this magazine, athletes are responsible for what's
in their bodies and they play Russian roulette when they fail to be
utterly diligent about the contents of their dietary and nutritional
supplements.
