1 Drugs In Sport

2 How substances come to be prohibited
For a substance or method to be prohibited, it must meet two of the following three conditions: The substance or method has the potential to enhance, or does enhance performance in sport. The substance or method has the potential to risk the athlete’s health. The substance or method is deemed to violate the spirit of sport

3 World Anti doping code Prohibited list:
At all times Anabolic agents – Steroids Hormones – EPO, HGH Beta 2 agonists – Ventolin Hormone antagonists and modulators Diuretics & masking agents

4 Prohibited In competition only
Stimulants Narcotics Cannabonoids Gluco-cortico steroids Alcohol (some sports) Beta Blockers (some sports)

5 Oxygen transfer or enhancement
Doping methods Oxygen transfer or enhancement Chemically or physically tampering with samples Gene doping

6 Why do some athlete’s use PHD
Anxiety Lack of confidence Determination to win Beliefs and attitudes Values’ Appearance Dependence

7 Environmental reasons
Influence of others Family pressure Media pressure National identity Financial rewards Public reaction Prestige / status

8 Narcotic analgesics Pain killers used by athlete’s to mask the pain of an injury e.g. Morphine, Pethadine Effects: Loss of balance Lack of concentration Sleepiness Slow Breathing Nausea / vomiting Aggravation of injury if keep training Blurred Vision

9 Anabolic steroids Manufactured version of testosterone (naturally produced in our body) Used to increase strength & power Reduces recovery time, more time for training

10 Health risks of anabolic steroids
Health risks of anabolic steroids. Medical experts see significant dangers in the use – and particularly the gross over-use – of anabolic steroids. Some of the effects are minor or only last while the drug is being taken; others are more serious and long-term. For example, anabolic steroids can cause high blood pressure, acne, abnormalities in liver function, alterations in the menstrual cycle in women, decline in sperm production and impotence in men, kidney failure and heart disease. They can also make both men and women more aggressive.

11 Stimulants Increased alertness Mask tiredness Hype you up to compete
Use will cause Rise in body temp* Rapid breathing Loss of co-ordination & balance Violent & aggressive behaviour

12 Diuretics Increases fluid loss in body in an attempt to decrease weight Used by athlete’s in weight category sports Also used to dilute urine so as to avoid detection of anabolic steroids

13 Cont… Use may cause: Faintness Dizziness Headaches Nausea Poor balance / co-ordination Muscle cramps Kidney failure Heart failure

14 Blood doping Injecting blood into the body to increase the number of red blood cells, thereby increasing the O2 levels in blood Increases energy availability & utilization Primarily for endurance athletes Risks of bacterial infections Sharing needles increases risk of Hepatitis & HIV. Blood clots, stroke or heart failure

15 Peptide Hormones & Analogues
Messenger hormones made of two or more amino acids Increase Muscle size and strength Two main types in Sport: HGH EPO

16 HGH Synthetic version of a hormone primarily responsible for determining height Used by athlete’s to build muscle and bone Health risks: Acromegaly – hands, feet & face grow very large Joint & muscle problems Diabetes

17 Health risks of human growth hormone If you believe all the hype – emanating mainly from drug manufacturers – hGH is a wonder drug that will remove wrinkles, reverse the ageing process, restore vitality and improve sleep. Nevertheless, there are some health risks. For example, too much hGH before or during puberty can lead to gigantism, which is excessive growth in height and other physical attributes. After puberty, inflated levels of hGH can cause acromegaly, a disease characterized by excessive growth of the head, feet and hands. The lips, nose, tongue, jaw and forehead increase in size and the fingers and toes widen and become spade-like. The organs and digestive system may also increase in size, which may eventually cause heart failure. Acromegaly sufferers often die before the age of 40. Excessive hGH in adults may also lead to diabetes.

18 EPO Pharmacological alternative to blood doping
Increases No. of red blood cells Risks (same as blood doping) If EPO levels are too high the body will produce too many red blood cells, which can lead to blood clotting, heart attack and stroke. In fact, EPO has been implicated in the deaths of several athletes.

20 Cont… Download the ‘world anti doping code’
1. List the fundamental rationale of the code 2. Who’s responsibility is it to ensure that prohibited substances do not enter their body? 3. What else may constitute an anti-doping violation?

21 Visithttp:// Watch the video on prohibited substance and methods

22 Testing You can be selected for testing anywhere, any time, and are subject to both random and targeted selection methods. An ASADA Doping Control Officer (DCO) will organise and manage the sample collection session, ensuring that all procedures are followed. A Chaperone will notify, accompany, and witness you providing a sample.

23 Athletes may at times need to use a prohibited medication to treat a legitimate medical condition. A Therapeutic Use Exemption (TUE) is an exemption that allows an athlete to use, for therapeutic purposes only, an otherwise prohibited substance or method (of administering a substance) which may be present during competition.
