Drugs in sport affecting future generations
In recent times we all know sports stars
such as Lance Armstrong and sporting codes such as the NRL and AFL have been
caught up with a variety of supplement scandals. The question at issue with
this widespread use of these substances is the affect it is having on the
younger generation of athletes coming through the ranks. Associate professor
Stephen Moston from the university of Canberra said, “Even 12-year-olds were
aware of performance enhancing drugs and why they were used, "They could
start to say `if they are using it, why don't I ‘ (news Limited 2013). Along with
the recent comments by professor Moston a study was taken place where
children’s response’s to the issue of taking illicit substances where “it will
greatly increase performance. This will increase renown and fame, leading to
increased salary", "enhance performance to become famous, or a
celebrity" and "makes a guy very cool" (news limited 2013). It
is important to recognise that upcoming younger athletics are looking up to
these individuals that have been undertaking in substance abuse and viewing it
as morally correct thing to do, however it is important that coaches at grass
root levels ensure they are informing younger athletics that success in the
sport in determined by perseverance rather than doping.
The continual doping allegations are not only affecting future
generations however it is causing issues for current athletics that are not
doping, for example recently rugby league player Jonathon Thurston was randomly
tested in the early hours of the morning then posted angrily on twitter
claiming they woke up his young child and created and unnecessary ruckus. This
however was a controversial issue, as many argued Thurston should have actually
praised doping authorities as an example to younger athletics identifying that
regular drug test at the top level are a common occurrence.
To conclude doping in sport needs to be strongly adhered to with
organisations such as the world doping authority needing to implement some sort
of structure or advisory seminars to ensure the future generations of athletics
are not involved in doping. Stronger bans and name and same policies should
also be implemented for those who conduct in illegal activity as doping at the
top level is a bad reflection of the sport and athletics which could therefore encourage
future generations to indulge in the same activity

Should Drugs in Sport be Legalised?
Should Drugs in Sport be Legalised?
The use of drugs in sport to enhance performance is not a new concept and is constantly improving. The continued abuse of illegal drugs by athletes has made it clear they are willing to risk their future health, respect for themselves, other participants and their sport to be the best. Since the illegalisation of performance enhancing drugs so that athletes do not have an ‘unfair’ advantage, organisations that do test for drugs in sport are fighting a losing battle as athletes and their trainers constantly devise new drugs and methods to beat drug testing (Bamberger & Yaeger 1997). For this reason, the question of controlled use of performance enhancing drugs in sport should be permitted has arisen.

For this reason, the question of controlled use of performance enhancing drugs in sport should be permitted has arisen.
It is no secret that performance enhancing drugs has been
used by athletes for decades and those athletes will risk almost anything to
gain a competitive edge. Bamberger & Yaeger (1997) reports of a scenario
from a poll in 1995 where 198 athletes made up of US Olympians or aspiring
Olympians were asked two questions: If they were offered a banned substance
that comes with the guarantee that they would not be caught and they would win
every competition they entered for the next five years, but then they would die
from the side effects of the substance. Would they take it? More than half said
yes. Research like this makes the notion of legalising performance enhancing
drugs seem extremely immoral and unacceptable for sports organisations to
expose their athletes to such risks, especially the athletes willingness to risk
so much to win. Not to mention a violation of the ‘spirit of sport’ that has
been created over the last century in elite and amateur competition.
However, Savulescu, Foddy & Clayton (2013) argues that
if performance enhancing drugs were legalised and freely available, it would be
the end of cheating. Moreover, if these drugs become legal and all athletes had
access to the same enhancements does that violate the ‘spirit of sport’ any
longer? Savulescu, Foddy & Clayton (2013, p. 667) uses the hypothetical
example, “if all athletes responded to the approved doping measures in the same
way and their performance improves in the same way, it that case, the results
of the finishing order of a cyclist race would remain unchanged”. Therefore,
there is no unfair advantage given; only the performance and the competiveness
are increased.
Another argument is that with the advances is sports science
and the high competitiveness of elite competition, sport discriminates against
the genetically unfit and is only for the genetic elite” (Wiesing 2011). Savulescu,
Foddy & Clayton (2013) states that nature is unfair, for example, Ian
Thorpe has very large feet which gave him an advantage that no other swimmer
can get, no matter how much they train or exercise. By allowing everyone to
take performance enhancing drugs, we level the playing field and remove the
effects of genetic inequality. Therefore, allowing performance enhancement
promotes equality which indeed is a characteristic of the spirit of sport.
The argument for and against the legalisation of performance
enhancing drugs in sport operates on different levels. There is the constant
battle that organisations face with drug testing. Performance drugs and methods
are continually improving to avoid detection and it is hard to justify the
costs that are created from this as it is a losing battle. On another level,
there is the argument that touches on the ‘spirit of sport’, the naturalist ideal
with performance in sport and how legalising drugs would permanently damage the
image of elite athletes and sport in general. Moreover, further studies are
needed to investigate the pro’s and con’s of the concept of legalising
performance enhancing drugs before any move to change laws and regulations can
be acted on.

The Physical and Psychological Effects of Anabolic Steroids on Athletes
The Physical and Psychological Effects of Anabolic Steroids on Athletes
The use of Anabolic steroids for performance enhancement in
elite athletes has been evident for over half a century. The use of steroids
has many physical and psychological effects on the individual both positive and
negative and is used by both males and females. This use is not only found in
elite professional athletes but also in amateur’s sportsman and sportswomen as
the drug is surprisingly cheap and is readily available on the black market
(Bowers, Clark & Shackleton 2009).
Anabolic Steroids are synthetic derivatives of the male
hormone testosterone which when injected or taken orally can show strong
effects on the human body that can benefit athletic performance (Hartgens &
Kuipers 2004). The first recorded use of steroids to enhance athlete’s
performance was in the early 1950’s by a doctor called John Ziegler. Dr Ziegler
was a physician for the American weight lifting team and became interested in
the use of steroids at the 1954 world championship when he learned of the
benefits of steroids from the Russian team doctor (Bowers, Clark &
Shackleton 2009). He then began trailing the drug on his athletes back in
America in 1959 which in turn started a snow ball effect on the uncontrolled
use of the drug by athletes. Once the weightlifters learned that this drug was
the reason for their rapid increase in strength, demand grew and the regulation
of the drug became uncontrollable. Bowers, Clark & Shackleton (2009, p.285)
states that Dr Ziegler lost control of the “experiment” and due to the
competitive nature of professional sport if ‘two tablets where good, four
tablets would be better’ according to the athletes. Over the next decade, the
use of steroids in American weightlifters, football players and strength
athletes was estimated at 50% (Bowers, Clark & Shackleton 2009).
For many
years, the medical community argued that there was no proof that steroids
enhanced athletic performance. It wasn’t until advances in medicine and drug
testing that the adverse effects of steroids on the human body became clear;
still it wasn’t until the late 1960’s that efforts were made to catch steroid
cheats in sport (McBride & Williamson 1993).
The most appealing effect of the use of Anabolic steroids is
the predicted increase in muscle mass and strength which far outweighs the
increase without the use of the drug. Hartgens & Kuipers (2004) concluded
that short term administration of anabolic steroids can increase strength about
5-20% of initial strength and an increase of 2-5kg in body weight. The same
study found that there was no reduction of fat mass and no effect on endurance
performance. However, George (2003) states that diet and intensive training are
equally important in producing the significant increase in strength. Although,
no matter how positive these results seem to be on performance, the negative
physical and psychological effects, both short and long term, far outweigh the
positive effects. Bahrke et al. (1992) found in a study done on weightlifters,
that short term psychological effects of steroid use included extreme
aggression, high irritability and insomnia. Apart from the increase in muscle
mass and strength, the negative physical effects according to Hartgens &
Kuipers (2004) include severe acne and the increased growth of body hair.
However, it has been found that the short term physical and psychological can
be reversed with discontinued use of the drug (George 2003).
It is the long term
effects of constant abuse of steroid use that cause permanent damage. Due to
the physiological effect of the body retaining water and salt when exposed to
steroid abuse, this has been proven to cause high blood pressure along with
high cholesterol (Hartgens & Kuipers 2004). After long term use of steroids
it has also been established that the body will begin to have a psychological
dependency which in turn, causes further issues. Hartgens & Kuipers (2004)
found that once a long term user stops using steroids, the dependence on the
drug caused psychological dissatisfaction with their body which is now being
called ‘reverse anorexia syndrome’. The discontinued use of long term abuse has
also been linked to withdrawal effects which lead to depression and in some
cases has lead to criminality and even suicide (George 2003). Also, constant
use of steroids has also proven that it disturbs the natural production on
testosterone in the body (George 2003). One long term physical effect that has
become common among steroid users is the development of gynaecomastia which is
an increase of breast tissue on the male and causes their chest to look
feminine. This is caused by the steroids creating excess testosterone levels in
the body and the bodies reaction to this is to turn the excess testosterone
into the female hormone estrogen (George 2003); which also can go on to cause
further psychological effects. Almost all
studies on the effects of steroids have been conducted on males and there are
very few done on the effects on women. One study done solely on women reported
results very similar results as studies done on males. Interestingly, apart
from finding an increase in muscle mass and masculinity in the subjects, the
study predominantly found major psychological changes in the women. 76% of the
subjects reported at least one adverse effect of the steroid use which included
major depression, development of eating disorders and chronic dissatisfaction
and obsession with their physiques (Gruber, A.J & Pope, H.G 2000). However,
much more research must be done to further understand these changes in women.
Solid medical research has
proven that all these physical and psychological effects are linked to the use
of anabolic steroids, but Bahrke, Yesalis & Wright (1990) show that these
vary greatly from person to person.
The use of Anabolic steroids for performance enhancement has
become a pressing issue in the sporting world. The studies done that have
proven the effects of the drug on the human body show there is an appeal for
all classes of athletes, from the elite to young men and women in youth
development programs, no matter how severe the negative effects of the drug
are. Thus, it is clear that more research must go into the use of steroids so
that people can be better educated about its dangerous properties and the abuse
of the drug to be controlled. However, in the foreseeable future, it’s evident
that the misuse of the drug will continue.

The Essendon Supplement Scandal
The Essendon
Supplement Scandal
The events that unfolded early February 2013 involving the
Essendon Football club were shocking as they were complex. Following a 12 month investigation by the
Australian Crime Commission which particularly targeted Drugs in The National
Rugby League and the Australian Football league; revelations from the Essendon
club and former players prompted the AFL and ASADA (Australian Sports
Anti-Doping Authority) to begin an investigation into the clubs supplement
programme during the 2012 season. The findings shocked both the AFL and the Australian
sporting community labelling 2012 as “the darkest year in AFL history” (The Australian 28 August 2013, p.36).
The issue came
to a head when the Essendon Football Club’s dealings with sport scientist
Stephen Dank came under investigation and were considered suspicious. The
Essendon club invited ASADA and the AFL to investigate their sport science
program in 2012 which was over seen by Mr Dank. The investigation prompted
Essendon to stand down their High performance coach Dean Robinson almost
immediately (Herald Sun 2013).
The
shocking findings of the investigation revealed that the Club’s players were
urged to have approximately 40 injections during the 2012 AFL season. Possibly
the most shocking part of the findings was that Mr Dank accused the clubs head
coach, James Hird, was also administered with these injections (Herald Sun
2013). Mr Dank stated that all involved where completely aware of what was
happening “I’m certainly very surprised given how much time we spent discussing
it with them (Players and coaching staff)” (The
Age 6 February 2013, p.2). Further allegations were raised when Mr Dank
told the Essendon club that he received a letter from WADA (World Anti Doping
Agency) which stated that the drugs he wished to administer where cleared as
legal. However, it became apparent that this was not true when an email from
WADA to Mr Dank prompted him to contact ASADA as “drug preparation may vary
between countries” (Jane Kuersch Journalism 2013). It was then
revealed that the Essendon players did sign consent forms that prescribed
weekly injections of an illegal substance. However, According to Essendon, this
doesn’t prove that they were administered with the injections (Herald Sun 2013).
ASADA then commenced interviews with Essendon players, quizzing them on around
35 substances linked to the Club and their former sport scientist Mr Dank. This
revealed that at least of 6 of these substances were banned for athletes (Herald
Sun 2013). The nail in the coffin was in June when star player for Essendon,
Jobe Watson on national television admitted to have been injected with one of
these illegal substances. He declared that “I signed that consent form” and “I
believed it was legal at the time” (Herald Sun 2013).
The
events that have occurred over the past year have been a long, grueling and
painful process for all involved. It has forced the governing bodies to react
in a shift and severe way to protect the image and reputation of the AFL and
indeed Australian sport as a whole. The Penalties handed down by the AFL and ASADA were the most
severe in the AFL’s history and has caused controversy itself. The penalties
included large fines, loss of draft picks and several members of the club being
fined, banned or they have stood down in disgrace.
In May, Ian Robinson stood down as Essendon’s CEO as he felt
a strong responsibility for the scandal saying he is accountable for everything
that happens to the club, even there supplement programs even though he played
no part in it or knew anything about it “We let down our players and their
families, I sit here today saying that our club let those people down and there
is no excuse in not knowing” (Herald Sun 2013). Chairman David Evans also
resigned in June for quiet puzzling reasons. Although playing no part in the
scandal, the night after Essendon lost a game against Hawthorn, he suffered a
physical breakdown. Mr Evans complained
of breathlessness, lighted headedness and struggling vision (Herald Sun 2013).
However, it was members of the
coaching staff that were involuntarily penalized as they did play a role in the
scandal. Despite strong support from Essendon fans, Head coach James Hird has
been banned for 12 months from the club and a decision will be made over the
next couple of weeks who his temporary replacement will be (The Age 17 September 2013, p.40).
Although, there have been strong claims that it is no longer whether Mr Hird
should couch Essendon again; it is whether he should ever couch again. “A man
with such flawed judgement, so disconnected from what is actually happening
about him, is surely a permanent risk” (The
Weekend Australian 24 August 2013, p.41). Mr Hird has been humble about his ban stating
he is “deeply sorry and does take a level of responsibility for what happened”
(The Herald 28 August 2013, p.81). Assistant
coach Mark Thompson has been fined $30,000 and the club manager, Danny Corrora
has been banned for 6 months for their role in the scandal (AFL 2013). It is also the clubs
it’s self that has been punished both in the short term and long term. The
clubs had been fined a total of 2 million dollars for bringing the game into
disrepute and also ejected from the 2013 finals (AFL 2013). This ejection would
have been a major blow for the club and the players as they were big contenders
in the completion in the lead up to the finals. In the long term, the club has
also been stripped of draft picks for the coming 2014 season (AFL 2013). This
will obviously affect their team and the club in not only next season but seasons
following as well.
The Essendon supplement scandal has both shocked and
negatively affected the AFL, ASADA, The Essendon football club, their fans and
the Australian sporting community. The investigation that revealed the controversy
has indeed put a stain on the AFL’s and Essendon’s reputation as both
professional organisations and role models for their great game. However, this
will be a wake up call for all sporting codes in Australia and will hopefully
bring positive changes in to avoid any further event that further damage
professional sport in Australia and the world.

Overview of Drugs in Sport Throughout History
Overview
of Drugs in sport throughout history
The
topic of Drugs in sport has been an ongoing issue in Australian and world sport
since the ability for athletes to have access to these banned substances began.
This concept of “ doping” began as early as Ancient Greek times when early
Olympians used extract of mushrooms and plants seeds to enhance their sporting
performance, even as early as the Roman period mix drugs where fed to horses
and even gladiators doped during the vigorous fights which where held during
this time (Turfman, S.T, 2004).
The use of drugs in sport however has transformed dramatically
since it began with new forms of doping methods developing as agencies such as
the world anti doping agency (WADA) have continued to crack down on these
illicit substances being used to increased sporting performance the elite
level. The types doping mechanisms that have been used in recent times include
anabolic steroids such as erythropoietin, human growth hormones, beta agonists
and diuretics. This use of drugs has transformed into other methods of doping
such as blood doping, gene doping and chemical and physical manipulation
through tampering with samples and infusing different bloods and genes (S,
Patil 2012). 1976
was the first major step towards abolishing the use of banned substances on the
world stage when The International Olympic Committee (IOC) banned the use of
steroids, however high profile and disgraced athletes such as the ex women’s
100 meters world record holder Marion Jones and US home Run record holder Barry
bonds used steroids such Tetrahydrogestrinone that weren’t traceable by world
doping agencies, nevertheless these doping cheats where caught and sanctioned
accordingly (Shermer, M 2008).
As more athletics continued being caught doping, individual
countries began setting up their own Anti doping agencies as increasing number
of “dopers” around the world made it difficult for one main agency to monitor
this ongoing and current issues in sport today. Therefore agencies such as
(ASADA) Australian sport anti doping agency, (UKAD) UK anti doping agencies and
(USADA) Us anti doping agency where set up as global counter act the ongoing
abuse of illicit substances in sport today (Barroso, O, & Rabin, O 2011).
Drugs in sport today however still has a long way to go in
controlling the use and supply at the elite level, there are always new ways
individuals using to cheat the system for example when metandienone was finally
being able to be detected many people where found using the banned substance
(Thevis, M. M. 2013). This use is a widespread and complex issue around the
world, for example in smaller countries with less control world wide rules and
regulations are often not adhered for example in Malta the issue of drugs use
among athletics has been considered an underground phenomenon with poor testing
programs therefore drug use in widespread and in fact common among these
athletics (Attard, L. 2011). This is a problematic situation in many developing
nations as in comparison western nations due to technological advancements have
continued to crack down on this issue for example in cycling the use of a
biological passport which tracks biological variables in a cyclist's blood and urine
over time, monitoring for fluctuations that are thought to indirectly reveal
the effects of doping (Hailey, N. 2011). Controversially this year Kenya faced
doping issues According to the BBC
Kenya faces strict emposements from WADA
“Since January 2012, 17 Kenyan athletes have been suspended for using
performance enhancing drugs compared with only two between 2010 and 2012” (
Telegraph sport 2013). Wada’s director David Howman listed Kenya as one on the
major problems for the organisation (Kamga J, P. 2003).
In totality the issue of drugs in sport is and always will be an
issue for world doping authorities and clean athletics as drug cheats are
finding new and innovative ways to beat the system in this technological
advanced world. It is important to consider that doping has been around for
centuries however as sport continues to become a part of culture and sporting
people becoming idols for children and individuals in many countries the continual
crackdown is essential for sport itself.
