Examination of Witnesses (Questions 120-139)
PROFESSOR IAN
MCGRATH,
MR JOHN
BREWER, DR
BRUCE HAMILTON
AND DR
ANNA CASEY
25 OCTOBER 2006
Q120 Chairman: Where is the cross-over
between SmithKline's main pharmaceutical research and putting
out products there which would have a performance enhancement
cross-over into athletics and into your nutritional drinks? Does
that occur?
Mr Brewer: Not to that great an
extent to be quite honest. GlaxoSmithKline has, as you know, a
major pharmaceutical business; we sit within the nutritional healthcare
business in the UK and so we have a very much ring-fenced budget
for sports science and sports nutrition research. However, it
would be wrong to say that we are not in contact with our colleagues
within our pharmaceutical business to look at other areas and
other opportunities, but by and large there is quite a distinction
between the pharmaceutical research that we conduct within a separate
arm of the business and the very focussed sports science and applied
sports science research that we conduct through our nutritional
business side.
Q121 Chairman: Do some of your general
products which I could take contain substances which would be
on the WADA banned list?
Mr Brewer: Absolutely, categorically
not. We have invested a huge sum of money in working with HFL
(the WADA accredited laboratory in Newmarket) to have a process
in place that enables us to say to the highest possible level
that all of our products are free of substances on the WADA banned
list. We have spent a lot of time and money in working closely
with HFL and with colleagues at UK Sport to raise the bar as high
as possible on not just the testing of the products but the whole
supply chain from the production of the raw materials through
to the production of the products themselves, the testing of the
products and then the distribution of those products and the supply
chain of those products to the athletes. We believe that it is
of absolutely fundamental importance that we can provide athletes
across a range of sports with a kite mark and quality assurance
that enables them to purchase their sport nutrition products in
the full knowledge that those products have been tested to the
highest possible standards.
Q122 Chairman: We have that on record.
Mr Brewer: Thank you.
Q123 Adam Afriyie: Are you confident
that GlaxoSmithKline have not invested in any organisations or
are not doing overseas research for another branch of the organisation
which may be influencing the development of human enhancement
technologies in sport?
Mr Brewer: I can only speak on
behalf of the nutritional business and I know the research that
we fund which is very much focussed on legal, performance enhancing
products. Obviously the rest of the pharmaceutical business of
GlaxoSmithKline is huge and sits outside my remit and obviously
that is done more for medical purposes and I would not want to
comment on that.
Q124 Chairman: Dr Hamilton, if you
find the nutritional companies are doing something but there is
not a great deal of research coming elsewhere, is there a push
from individual athletes or coaches or sports clubs or individual
sports for more research?
Dr Hamilton: There is although
in my experience athletes are not so much interested in research
but outcomes and they will jump on a product or a technique or
a strategy that they will perceive to work on the basis of no
research at all. One of the issues that we have is that I am pushed
into situations and encouraged to use techniques or procedures
which are based on very little evidence. The push does not so
much come for research, it comes to the utilising techniques.
Sports medicine in this country is a relatively new profession
and one of the underdone areas at this stage is access of sports
medicines, sports physicians and practising clinicians to research
and that is a real limitation to our practice at the moment.
Q125 Chairman: Professor McGrath,
what do you think are the main developments in terms of the illegal
human enhancement technology at the moment? Where should we be
looking as a Committee?
Professor McGrath: I think pharmacology
will always develop; drugs are continuously developing, they have
been for the last fifty years and that will carry on. One of the
difficulties is that sports people are interested in outcomes
and are very susceptible to snake-oil salesmen. People come along
with things that they say will help without any substantial scientific
background to explain how that was developed and what the consequences
are. I think pharmacology will continue to develop and we will
have to try to keep one step ahead of that somehow. There are
only three things that drugs can do: they can enhance physiological
performance (heart, lungs, muscles, et cetera); they can cheat
the brain safety devices and they can accelerate healing. Accelerating
healing is probably something that is a good thing. The point
of training is to make physiology better and it is a question
of whether you are going to harm people by the drugs that you
develop to speed that up. Probably the most dangerous things are
the things that cheat the safety mechanisms of the brain. The
drugs themselves might be difficult to detect and the consequences
that they have may be difficult to detect. I think we will have
to keep one step ahead of the game. We have not been very good
at actually understanding what illegal drugs do. We have been
quite quick to make them illegal and say that they might do harm,
but we are not actually very good at understanding exactly what
they do to the body. My thesis would be that if we understood
better what they did to the body we would be one step ahead and
we would be looking at the consequences of the drugs rather than
having to search for unknown chemicals. It is obviously in the
interests of governments and sports people all over the world
to do whatever they can to enhance performance and if we want
Britain to be winning medals what we have to do is find ways of
stopping them using illegal techniques. I think probably finding
ourselves ways of enhancing our athletes' performance is not where
we should be putting the effort in; we should be putting the effort
into making sure that we understand the things that people are
doing to their athletes so that we can be one step ahead to stop
it.
Q126 Mr Flello: Dr Hamilton, I would
like to return to some of the points you were saying about the
challenges and the issues and the overlap there. Can I draw out
a little bit more about the main challenges to a medic in the
sporting world?
Dr Hamilton: We have to differentiate
between the elite sporting world and the mainstream sports because
the pressures and the management of athletes is entirely different.
My role is one of both trying to maximise the health and wellbeing
of the athletes, allow them to recover from training more quickly,
allow them to progress and recover from injuries as rapidly as
possible. I am also linked in closely with the science side of
the sport trying to maximise the performance. Quite often maximising
performance will be in direct conflict with the health and wellbeing
of the athlete. We can encourage someone to recover quickly and
allow them to do more training, but that training may well be
having long-term consequences for them in terms of osteoarthritis,
in terms of injuries that may come on post the competitive period
that they are interested in. There is a conflict there all the
time between my role of trying to enhance the performance and
trying to manage their injuries, and that is something we deal
with on a day to day basis. There are conflicts in the area of
medication use. What is illegal and perceived to be inappropriate
to use today may well not be tomorrow and athletes are very quick
to jump on that. A relevant example would be pseudoephedrine which
was prohibited until a couple of years ago when it was taken off
the list becauseI am uncertain as to exactly why it was
taken offit was presumably so commonly found in over the
counter medications that it was difficult to control its use.
It was taken off the list but subsequently it has been shown in
a research paper with Birmingham University and Asker Jeukendrup
to have performance enhancement capabilities. Athletes will want
to use that now and I am in no position to say they cannot use
it, so we try to control it from a health perspective. Then the
athlete will ask the question, "If I can use that, why can't
I use this?" and it is very difficult to argue against that
when two substances, methods or techniques or whatever it is will
actually have the same risk benefit profile.
Q127 Mr Flello: What are the methods
you can use legally to enhance performance in a competitive environment?
Dr Hamilton: On the day performance
enhancement pseudoephedrine is a product that legally people should
be using within health limits. Creatines are another product that
have been shown to have some performance enhancing benefits for
certain events. We use a number of neuro-muscular stimulation
techniquesmanual techniquesto try to enhance the
performance on the day to keep the muscles activated. Appropriate
warm-up, appropriate fluid and appropriate diet are areas which
are most commonly neglected and are big players.
Q128 Mr Flello: Is there a tension
on you to short cut some of those basics?
Dr Hamilton: No. There are always
challenges to try to maximise everything, but my personal interaction
with athletes is that they will not be challenging me to use illegitimate
means; they would want me to push the envelope of legal means.
Yes, I will be pushed to maximise it but within legal boundaries.
Q129 Mr Flello: Dr Casey, you mentioned
about trying to wean the troops off hamburgers and certainly through
the Armed Forces Parliamentary Scheme there seems to be a fairly
staple diet at training camps at Pirbright and Sandhurst and the
like. It has been commented that trying to get the troops off
smoking would have more of an impact than anything else. Is there
any research going on in that particular area in terms of looking
at the way troops lead their social lives?
Dr Casey: We are not doing any
research specifically aimed at smoking. I cannot speak on behalf
of the Ministry of Defence, but certainly it is my understanding
that there is an on-going discussion about smoking. It has been
an on-going issue for many years, as you can imagine. A lot of
the studies we do with basic recruits do not just cover the physiological
side of training; we also do a lot of profiling in terms of their
physiological responses to stress and also their coping mechanisms
and that type of thing. In terms of the sort of person they are,
that is something that is the subject of on-going research. We
do not do a lot of social research within our department with
these groups of people, but going back to the question of diet,
I do not think it is any secret that certainly in the past the
diets have had room for improvement but there has been a major
overhaul over the last two years in the whole area of military
feeding. When I started working with the military I started very
much at the high performance end, ergogenic performance enhancement,
and I have taken a step back at every stage and we are right back
at the beginning now and we are really trying to address the entire
issue of military feeding right from the recruit who walks through
the door. That is where the big difference would be. I have mentioned
that before and I agree with Bruce Hamilton that the biggest difference
to your performance whether it is physical performance or cognitive
performance, your mood state, how you train, how you recover,
all of those things will be governed by what you are eating on
a daily basis, not what supplements you are taking and what drugs
you are taking or what you can get hold of. It is your daily diet,
it is your traininghow good is the training, how progressive
is it, are you breaking the recruits in too earlyall of
which has been addressed over the last couple of years. There
has been a major overhaul of the whole of military feeding, from
your basic recruit right through to servicewomenconcentrating
on pregnant women and also on special forcesand that is
on-going at the moment.
Q130 Mr Flello: Is that an area where
the military is benefiting from research that has been done over
many years in the sports field?
Dr Casey: Not necessarily the
sports field but certainly in the areas of public health and general
nutrition.
Q131 Mr Flello: In terms of the quality
of legal research in this country, how does it compare to the
international position? Who are the world leaders in this area?
How can the UK be the best compared to them?
Professor McGrath: I think that
Britain is up there with the leaders in this area. Maybe Denmark,
Sweden, Canada, Britain, the US, Australia, South Africa tend
to be the leaders in this area. There is a big potential for making
it better. There is better science out there that could be applied
to this area if, as I said, there was some driver to make people
do it. In the last research assessment exercise of the universities
in Britain there were only five groups that had a five star rating.
That, in the whole of Britain, is not what you would be driving
towards for an area of academic endeavour. Of these five three
were very much technologically oriented groupsLoughborough,
Manchester Metropolitan, Liverpool John Mooresand only
Birmingham and Glasgow were embedded in biomedical science rather
than in sport. There is a big potential there. There are a lot
of other places in Britain who could be doing this kind of research
if there was some driver. You would expect £500,000 of one
MRC grant but there just are not the resources going into this
area.
Q132 Mr Flello: Mr Brewer, perhaps
I could ask for your perspective on the same area. Obviously an
organisation like yours is a multi-national one, so how would
you see the comparison of the UK research in that field?
Mr Brewer: I guess we are in the
fortunate position that we can cherry pick where we have our research
done and it would be wrong to say that we do not look overseas
to see if there are any opportunities there. The fact that four
of the five universities that we currently fund are in the UK
I think is testimony to the fact that we do rate very highly the
quality of the academic research that can be obtained at key centres
of excellence in the United Kingdom. Very important for us is
working with academics who have the ability to do firstly high
quality science but then work with us to translate that science
into meaningful claims and meaningful language that we can then
use to develop next generation products and to translate to the
athletes and the coaches and the sports science and sports medicine
support staff the benefits of those products and the benefitsas
Dr Casey has saidof the correct nutritional strategy to
support the supplementary parts of their diet that give them that
extra half of 1%. I think we are very comfortable with the quality
of academic research that we can obtain within the United Kingdom.
The outputs that we obtain from that are very good, they have
helped us to develop products over the years, they have helped
us to develop new claims over the years. I think perhaps the classic
claim from us from a business perspective is when we funded research
at Loughborough University back in the late 1980s where we were
able to show that isotonic drinks can improve performance by 33%.
That was something that was generally known within the world of
sports nutrition but it enabled us to take our products one stage
further and to educate the coaches and athletes accordingly. That
is very important to us, that delivery of an education message
to support the product development which we can only get by working
closely with academics.
Q133 Dr Iddon: Professor McGrath,
when you said in your written evidence to the Committee that "much
research in sports related topics is not cutting edge and does
not have sufficient scientific depth" were you referring
only to UK work or were you referring to global work when you
said that?
Professor McGrath: I think it
would be a global phenomenon. It is an area where you can produce
certain outcomes in terms of physiological studies of athletes
quite cheaply, but to achieve any depth to move the thing forward
in terms of science it is much more expensive. It is incontrovertible,
that where we are moving forward, in areas such as cardiovascular
research, cancer research, the quantities of monies involved are
many multiples of the kind of money that goes into sports related
research. Because the drivers are not there, the science is not
being applied there, but the science could be applied. The science
of physiology, biochemistry and molecular biology is all there,
but where would you get the money to apply it to sport?
Q134 Dr Iddon: In your written evidence
you have said that the whole science base is there, so can you
perhaps tell the Committee what Britain needs to do to change
this position if we are to be a world leader in our athletics
with a view to the 2012 Olympics?
Professor McGrath: I could say
you are too late for the 2012 Olympics, but the fact is that you
could do things now if you put significantly more money into the
system. I do not know where you would get it, but I would say
that, would I not? If you put more money into the area of physiological
research you would get some outcome, but I really do think that
in terms of understanding the physiology behind these various
forms of enhancement, if we did understand that better we would
be able to set better limits. One of the difficulties in defining
what should be illegal is often that you have achieved something
that is way outside the norm, but we are not very good at defining
the norm so we get into legal struggles about whether something
is 30% more than anybody else would ever have, or is it 300 times.
We really do not understand those kinds of things. We are quite
good at measuring oxygen consumption and heart rates but we are
not very good at the fundamental science that underlies it. What
are the genes that are expressed when you take these drugs? Rather
than looking for the drugs, we should look at the physiological
effects of them. This is all possible; this is not science fiction.
If more resources were going into this area we could be one step
ahead of the dopers because we would be picking up the things
that they are making the body do rather than picking up the things
that go into the body.
Q135 Dr Iddon: With respect, that
is all very negative. What we are looking for from our witnesses
is to be able to make recommendations to government on the way
forward. In an ideal world where do you think the money should
be coming from if it were available, and who do you think should
be responsible for allocating it?
Professor McGrath: I think it
is quite a good thing to look at the different research councils
for different purposes. You could persuade the Medical Research
Council to be involved if you saw this as a continuum of improving
human performance/health with athletic performance being at one
end of that spectrum and illness being at the other end of that
spectrum. They would debate it quite strongly with you perhaps.
I think the Medical Research Council could be involved there but
the Biological Research Council could also be involved in terms
of applying the best of modern biology to these sports related
and health related issues.
Q136 Dr Iddon: The BBSRC?
Professor McGrath: Yes, the BBSRC.
I looked at their website in vain for sports and exercise related
topics. They actually had an acronym "sport" but it
was nothing to do with sport. I do not think you could persuade
them to use part of their existing budget to do it. Money would
need to come in from outside and it would need to be a substantial
amount of money, £20 million or something like that. A project
costs half a million pounds and you would probably need to have
consortia working on this. You mentioned Britain versus the rest
of the world. Any of these projects that we are involved inwhether
it is looking at East African runners or some other aspect of
physiologynearly always involve an international consortium
of scientists because in order to get enough good groups who are
the best in the area you have to work in that way.
Q137 Dr Iddon: If you were Colin
Blakemore tomorrow where would you invest your money in this particular
area? In other words, what would be your top three priorities?
Professor McGrath: My top priority
would be looking at the gene expression consequences of some of
the enhancement technologies. EPO would be a place to start. What
are the gene expression consequences of technologies which enhance
the oxygen carrying capacity of the blood. I think that would
be one area that I would look at. I would also want to go for
a couple of the most common types of drugs that are used illegally
and I would try to look at the gene expression consequences of
giving these drugs and the physiological consequences. It would
not be cheap because there is no point in doing a study with half
a dozen people here; you are talking about doing it with different
populations: elite athletes, normal plodding athletes, normal
members of the public.
Q138 Chairman: You cannot do it on
elite athletes.
Professor McGrath: You can do
it on sub-elite athletes if they are out of competition. That
is the way these projects are planned. You cannot do the illegal
doping with the elite athletes, but you can do the difference
between them being at altitude and not being at altitude, those
kinds of things, and you can compare it with other groups who
are only a little bit off them in terms of percentage performance.
You can do those things; they are ethically possible. However,
nobody is doing them because why would you?
Q139 Dr Iddon: The Australians are
doing it; we saw that in Australia and they do not believe that
this altitude stuff makes more than half a per cent difference
(that is what they told us). Do the other three witnesses before
us this morning agree with Professor McGrath's analysis about
who should be directing the money and where the priorities lie?
Dr Casey: Yes. We obviously have
a slightly different experience. The Ministry of Defence do not
tend to fund research directed at sport so that is not a major
issue.
