Learning ObjectivesLearning Objectives
By the end of this lesson pupils should:
Know about the different categories of drugs (performance-enhancing and recreational)
Be able to explain the impact of performance-enhancing drugs on wellbeing and performance
Be able to explain the effects of smoking and alcohol on general health
What is a drug?What is a drug?
A drug is a substance that can be taken in a variety of ways to produce expected and welcome physical and or psychological effects on the person taking it
Drugs may also cause some effects that are both unpleasant and unwanted. These are known as side-effects.
There are two main categories of drugs: - Performance-enhancing - Recreational
Performance-Enhancing Performance-Enhancing DrugsDrugs
Performance-Enhancing Performance-Enhancing DrugsDrugs
Performance enhancing drugs can enhance a person’s performance in some way, either in physical activity and training, or daily life. Performance-enhancing drugs include:
Anabolic steroids Beta blockers Diuretics Narcotic analgesics Stimulants Peptide Hormones (erythropoietin/EPO)
Anabolic SteroidsAnabolic Steroids
Anabolic SteroidsAnabolic Steroids
Anabolic SteroidsAnabolic Steroids Drugs that mimic the male sex hormone testosterone and promote bone and muscle growth
The most commonly used to enhance performance in sport, because they produce improvement quickly
They increase muscle mass and develop bone growth, therefore increasing strength while at the same time allowing the athlete to
train hard and recover quicker
Anabolic SteroidsAnabolic Steroids
Steroids increase aggression and some athletes take it mainly for this reason. The other side effects for anabolic steroids include:
- Deepening of voice and growth of facial hair - Increased risk of heart attacks and strokes - High blood pressure - Liver disease - Increased risk of muscle injury - Infertility in women - Death
Beta BlockersBeta Blockers
Beta BlockersBeta Blockers
Beta BlockersBeta Blockers Drugs that are used to control the heart rate and have a calming and relaxing effect
Commonly prescribed for people with heart problems as they maintain a low heart rate and lower blood pressure. As a result stress levels and anxiety are reduced
Used in target sports where steadiness and precision are required, because they reduce the heart rate
Beta BlockersBeta Blockers
Beta Blockers can reduce a fit person’s heart rate to a dangerous level. The other side-effects of beta blockers include:
- Nausea and diarrhoea - Tiredness - Depression - Insomnia and nightmares
DiureticsDiuretics
DiureticsDiuretics
DiureticsDiuretics Drugs that elevate the rate of urine reduction
Certain foods are natural diuretics, but some synthetic diuretics are banned
Diuretics increase the amount of urine produced and increase kidney function, therefore speeding up the elimination of fluid from the body
This can help performers who need to lose weight, such as boxers and jockeys.
DiureticsDiuretics
Diuretics are also taken to reduce the concentration of other banned substances in the urine. The side effects of diuretics include:
- Dehydration - Dizziness and nausea - Muscle cramps - Kidney failure
Narcotic AnalgesicsNarcotic Analgesics
Narcotic AnalgesicsNarcotic Analgesics
Narcotic AnalgesicsNarcotic Analgesics Drugs that can be used to relieve pain
These are used more commonly in combat sports as well as used to return to sport more quickly after injury
These drugs act by depressing the central nervous system and give relief from pain injuries
However by allowing an injured player to take part, can increase the risk of severe injury
Narcotic AnalgesicsNarcotic Analgesics As well as heightening the risk of getting longer lasting injuries, the side effects of narcotic analgesics include:
- Loss of concentration - Loss of balance - Loss of coordination - Emotional effects, including hallucinations
StimulantsStimulants
StimulantsStimulants
StimulantsStimulants
StimulantsStimulants Drugs that have an effect on the central nervous system, such as increased mental and/or physical alertness
This group includes amphetamines, ephedrine, and cocaine as well as caffeine and nicotine
They increase alertness by stimulating the CNS and help overcome tiredness
StimulantsStimulants Stimulants are also used recreationally as well as to enhance performance, the side effects of stimulants include:
- Insomnia - Irritability - Irregular heart beat - Increased heart rate - High blood pressure - Addiction
Peptide Hormones & EPOPeptide Hormones & EPO
Peptide Hormones & EPOPeptide Hormones & EPO
Peptide Hormones & EPOPeptide Hormones & EPO Drugs that cause other hormones to be produced
As well as increasing muscle growth and helping with recovery, they increase the number of red blood cells, allow the body to carry extra oxygen
We produce hormones naturally, but they can be synthetically produced by drugs
Peptide Hormones & EPOPeptide Hormones & EPO Human growth hormones (HGH) increase muscle development, which is why these are used by several sports participants
HGH is thought to have fewer side-effects than steroids
Erythropoietin (EPO) is used to treat people with anaemia and it increases the production of red blood cells and therefore the amount of haemoglobin available to take up oxygen
Recreational DrugsRecreational Drugs
Recreational DrugsRecreational Drugs Most people use recreational drugs on a regular basis. The obvious ones are caffeine, nicotine and ethanol (alcohol)
Although these drugs are legal, they can still have quite negative side effects such as:
- Addiction - Stained teeth and gum disease - Lung cancer - Heart problems - Contribution to death
Smoking & NicotineSmoking & Nicotine
Smoking & NicotineSmoking & Nicotine Smoking damages the cardiovascular system, in particular the heart and the oxygen- carrying capacity of the blood, and the blood vessels
This has a negative effect on fitness, especially aerobic fitness, and often results in poorer performance
Nicotine, the drug contained in cigarettes, is a stimulant which raises alertness and is highly addictive
AlcoholAlcohol
AlcoholAlcohol Alcohol is banned in sports such as shooting and archery, where it may be used as a sedative (have a calming effect)
It is also banned in sports where it is considered a safety risk, such as motor sports, because it slows down reaction times and impairs judgement
The long-term effects of alcohol include a form of liver damage known as cirrhosis
