Drugs in sport — AQA A-Level Physical Education

Drugs in sport is a core topic in AQA A-Level Physical Education, focusing on the use of prohibited substances and methods to enhance performance. It covers the types of drugs (e.g., anabolic steroids, stimulants, EPO, diuretics), their physiological effects, side effects, and the ethical and legal implications. Understanding this topic is essential for analysing contemporary issues in sport and evaluating strategies to maintain fair play.

This topic links closely to exercise physiology, ethics, and the role of national and international governing bodies such as WADA and UKAD. Students must be able to apply knowledge to real-world examples, discuss the pressures athletes face, and evaluate the effectiveness of anti-doping measures. It often appears in exam questions requiring explanation, analysis, and evaluation, making it a high-value revision area.

• →Anabolic steroids: synthetic testosterone that increases muscle mass and strength; side effects include liver damage, aggression, and hypertension.
• →Stimulants: increase alertness and reduce fatigue; side effects include insomnia, anxiety, and heart problems; banned in competition.
• →Erythropoietin (EPO) and blood doping: increase red blood cell count and oxygen delivery, boosting endurance; risks include blood clots and stroke.
• →Diuretics: promote water loss to make weight or mask other drugs; side effects include dehydration and electrolyte imbalance.
• →Anti-doping strategies: testing (urine/blood), education, sanctions, and biological passports; WADA sets the prohibited list.

• Social pressure from media, public and national expectation can push performers towards doping to meet medal or selection targets.
• Financial incentives such as sponsorship, prize money and funding can motivate doping when winning brings reward.
• A win-at-all-costs culture and influential coaches, teammates or entourages can normalise and facilitate doping.
• Psychological reasons include believing rivals dope, seeking confidence or anxiety control, and wanting a competitive edge.
• Personality traits such as perfectionism, ego orientation and moral disengagement can increase the likelihood of doping.
• Anabolic steroids increase muscle protein synthesis, promoting muscle growth and strength gains, but can cause liver damage, reduced sperm production and mood disturbance.
• Stimulants increase heart rate, blood pressure and arousal, delaying fatigue, but can cause overheating, irregular heartbeat and anxiety.
• Beta blockers slow heart rate and reduce tremor and anxiety, but can reduce cardiac output and therefore endurance performance.
• Diuretics reduce body mass by increasing urine output, but risk dehydration and electrolyte imbalance, which impair thermoregulation and muscle function.
• Physiological effects can improve one performance component while harming health or another component, so the overall effect on the performer is not uniformly positive.
• EPO stimulates red blood cell production in bone marrow, increasing haemoglobin concentration and oxygen-carrying capacity.
• The physiological benefit is delayed fatigue and improved endurance performance because more oxygen reaches working muscles.
• EPO raises blood viscosity, increasing the risk of blood clots, stroke and heart attack.
• EPO can suppress natural EPO production, and it is banned in sport.
• The performance effect is specific to endurance events and is not unlimited; health risks can outweigh benefits.
• Anabolic steroids are synthetic derivatives of the hormone testosterone.
• They are used to increase muscle mass, strength and power and to aid recovery from training.
• Typical users include sprinters, throwers, weightlifters, rugby players and bodybuilders.
• Physiological effects include increased protein synthesis and muscle hypertrophy.
• Health risks include liver and kidney damage, raised blood pressure, acne and reduced sperm production.
• Males may experience testicular atrophy and gynaecomastia; females may experience masculinisation.
• Psychological effects include mood swings and increased aggression.
• They are prohibited by the World Anti-Doping Agency and detected by urine or blood testing.
• Beta blockers block beta-adrenergic receptors, reducing the effects of adrenaline and lowering heart rate and blood pressure.
• They reduce muscle tremor and anxiety, improving steadiness and fine motor control for athletes.
• Typical users compete in precision sports such as archery, shooting, snooker, and golf.
• Health risks include bradycardia, hypotension, fatigue, dizziness, and dangerous bronchospasms in asthmatics.
• WADA prohibits beta blockers in competition only in certain named precision sports, not universally across all sports.
• Identifies at least two positive implications for the sport, such as increased media interest, higher performance standards or greater spectator appeal.
• Identifies at least two negative implications for the sport, such as damaged reputation, loss of sponsorship, legal sanctions or reduced trust.
• Identifies at least two positive implications for the performer, such as improved performance, faster recovery, financial gain or increased confidence.
• Identifies at least two negative implications for the performer, such as health risks, bans, loss of income, reputational damage or psychological harm.
• Applies implications to a specific sport and performer, showing how drug taking affects both the sport and the individual.
• Uses accurate terminology such as anabolic steroids, EPO, blood doping, WADA, UKAD, banned substances, therapeutic use exemptions.
• Develops a balanced argument that weighs positives against negatives for both sport and performer.
• Reaches a justified conclusion about the overall impact of drug taking on the sport and the performer.
• Anabolic steroids increase muscle protein synthesis, causing muscle hypertrophy and increased strength.
• EPO increases red blood cell production, raising haemoglobin and oxygen-carrying capacity for aerobic endurance.
• Human growth hormone increases muscle mass and bone density.
• Beta-blockers reduce heart rate and tremor, improving precision and reducing anxiety.
• Diuretics increase urine production, causing fluid loss and weight loss.
• Blood doping increases red blood cell count, improving oxygen delivery to muscles.
• Each adaptation carries health risks such as cardiovascular strain, liver damage or dehydration.
• Psychological rewards for the performer: raised confidence, lowered pre-competition anxiety, stronger self-belief and increased motivation to train and compete.
• Social rewards for the performer: praise and approval from coaches, teammates and spectators, plus media profile, sponsorship, selection and enhanced status.
• Rewards for the sport: higher performance standards, record-breaking performances, greater spectator interest, media coverage and commercial income.
• Rewards can be immediate and visible while health costs are delayed, which helps explain continued doping despite known risks.
• Correct classification matters: performer versus sport, and psychological versus social, must be distinguished in the chosen option.
• Current health effects: raised blood pressure, cardiac arrhythmia, liver and kidney strain, hormonal disruption, mood disturbance, aggression, insomnia and greater injury risk.
• Future health effects: heart disease, stroke, certain cancers, organ failure, infertility, dependence and lasting psychological problems such as depression.
• Timing matters: some harms appear during or soon after use, while others accumulate over years and may only emerge after retirement.
• Different drug classes carry different risks, for example anabolic steroids and liver or hormonal damage, stimulants and cardiac events, so the option must match the substance.
• Health harm applies to the individual performer and can also affect others through contaminated or shared supply.
• Social repercussions for the sport include damaged reputation, loss of public trust, reduced sponsorship and media coverage, and negative role-model status.
• Social repercussions for the performer include public shame, criticism from fans and media, damaged relationships with teammates, coaches and family, and loss of status.
• Psychological repercussions for the performer include guilt, anxiety, depression, loss of self-esteem, identity crisis and fear of detection.
• Psychological repercussions for the sport include reduced confidence in fair play among clean athletes and spectators, and a culture of suspicion.
• Consequences can be short-term (ban, immediate criticism) or long-term (career loss, reputational damage, mental health issues).
• The severity of repercussions depends on factors such as the type of drug, the level of competition, whether it is a first or repeat offence, and the performer's public profile.
• Testing strategies: random testing, target testing, out-of-competition testing, and testing of blood and urine samples.
• Biological passport: monitoring an athlete's blood variables over time to detect abnormal changes that may indicate doping.
• Whereabouts rules: athletes must provide details of their location so they can be tested without notice.
• Sanctions: bans from competition, fines, removal of medals and titles, and disqualification of results.
• Education: teaching athletes about health risks, ethical issues and the consequences of doping.
• International cooperation: organisations such as WADA set and enforce rules across sports and countries.
• Intelligence and whistleblowing: encouraging reports of doping and investigating suspicious patterns.
• Explains arguments for drug taking, such as performance enhancement, faster recovery, financial gain, and personal autonomy.
• Explains arguments against drug taking, such as health risks, unfair advantage, cheating, and damage to sport's reputation.
• Explains arguments for testing, such as deterrence, detection, protecting clean athletes, and safeguarding athlete health.
• Explains arguments against testing, such as cost, privacy concerns, false positives, and unequal testing burdens.
• Uses sporting examples or scenarios to illustrate each argument and its consequences.
• Analyses the balance between individual freedom and the integrity of sport.
• Reaches a supported judgement on the extent to which drug taking and testing can be justified.

• 💡Sort each option into social or psychological before choosing, since the stem may ask for one category only.
• 💡Reject options that describe consequences of doping rather than reasons for it.
• 💡Look for options that name a specific pressure, such as sponsorship or fear of losing selection, rather than a vague 'wanting to win'.
• 💡Link each drug to a named physiological mechanism and then to a specific performance component, such as strength, endurance or tremor control.
• 💡Use comparative language, such as 'increases', 'decreases' or 'delays', to show the direction of the physiological effect.
• 💡When a question asks about the performer and their performance, include both health effects and performance effects, not just one.
• 💡State the mechanism first: EPO stimulates red blood cell production, which raises haemoglobin and oxygen transport.
• 💡Link the mechanism to a specific endurance performance outcome, such as delayed fatigue in a long-distance event.
• 💡Include at least one serious health risk, such as increased blood viscosity leading to clots, stroke or heart attack.
• 💡Link each drug to a named type of event or athlete so the answer is specific rather than generic.
• 💡Use correct terminology such as testosterone, protein synthesis, muscle hypertrophy and gynaecomastia.
• 💡When asked to evaluate, give both the performance benefit and the health or ethical cost before reaching a judgement.
• 💡Specify that beta blockers are banned only in certain precision sports when discussing WADA regulations.
• 💡Name specific precision sports (e.g., archery, shooting) where beta blockers give an advantage to make your answer concrete.
• 💡Use correct physiological terminology, such as beta-adrenergic receptors, bradycardia, and cardiac output, when describing effects.
• 💡Plan your answer to cover four categories: sport positives, sport negatives, performer positives, performer negatives.
• 💡Use specific examples from real sports to support each implication, but avoid naming individuals unless you are certain of the facts.
• 💡Link each implication back to the question by explaining the effect on the sport or the performer.
• 💡Conclude with a judgement about which implications are most significant and why.
• 💡Link each drug to its specific physiological adaptation and the performance benefit it provides.
• 💡Remember that adaptations can be harmful; mention health risks where relevant.
• 💡Use accurate terminology such as haemoglobin, oxygen-carrying capacity, muscle hypertrophy and protein synthesis.
• 💡For MCQ, eliminate options that confuse the effects of different drugs.
• 💡Read the stem carefully to check whether it asks about the performer, the sport, or both, then eliminate options that only cover the other category.
• 💡Sort each option into psychological, social or sport-level before choosing, rather than judging whether it sounds generally positive.
• 💡Reject any option describing a health harm or a physiological mechanism, because those belong to other statements in this section.
• 💡Check whether the stem asks about current, future or both types of harm, then eliminate options that only cover the other time frame.
• 💡Match each option to a plausible drug class; an option linking a stimulant to liver damage or a steroid to sudden sedation is likely to be wrong.
• 💡Prefer options that name a specific body system or condition over vague statements such as 'it is bad for you'.
• 💡Separate your answer into 'for the sport' and 'for the performer' to ensure you cover both parts of the statement.
• 💡Use specific examples of social and psychological effects rather than vague words like 'bad' or 'upset'.
• 💡Link each repercussion to a real consequence, such as loss of sponsorship, a ban, or mental health difficulties.
• 💡Name specific strategies such as random testing, biological passports and whereabouts rules.
• 💡Explain how each strategy works, not just what it is called.
• 💡Link strategies to the aim of eliminating doping, for example by increasing detection or deterrence.
• 💡Plan both sides before writing: for drug taking, against drug taking, for testing, against testing.
• 💡Use specific examples or scenarios to show consequences for performers, teams, and spectators.
• 💡Finish with a clear judgement that weighs the arguments rather than repeating them.
• 💡Read the specification line carefully: it tells you what will not be examined, so do not over-prepare procedures.
• 💡Direct your notes towards arguments for and against drug taking and testing.
• 💡If a question mentions testing, answer with ethical and sporting arguments, not procedural steps.
• 💡Always name specific drugs and link them to their effects and side effects; vague answers like 'drugs make you better' score zero.
• 💡For evaluate questions, provide a balanced argument with strengths and weaknesses of strategies, then reach a justified conclusion.
• 💡Use real-life examples (e.g., Lance Armstrong, Dwain Chambers) to support your points and show application of knowledge.

• Treating doping as purely a moral failing; correction: social pressures such as expectation, money and culture, plus psychological factors, explain why performers take the risk.
• Assuming only financial gain matters; correction: psychological drivers such as confidence, anxiety control and perceived unfairness also operate.
• Confusing social with psychological reasons; correction: social reasons come from the environment and others, while psychological reasons come from the performer's own beliefs, emotions and traits.
• Believing doping is confined to one sport or nation; correction: the pressures described apply across elite sport generally.
• Misunderstanding: all drugs improve performance. Correction: some, such as beta blockers, can reduce cardiac output and endurance, so the effect depends on the drug and the performance demand.
• Misunderstanding: physiological effects are the same for every performer. Correction: effects vary with dose, individual physiology, training status and the specific sport demands.
• Misunderstanding: diuretics improve performance by reducing mass. Correction: the main physiological risk is dehydration and electrolyte imbalance, which can impair thermoregulation and muscle function.
• Misunderstanding: stimulants only affect the brain. Correction: stimulants also raise heart rate and blood pressure, so they have cardiovascular as well as psychological effects.
• Misunderstanding: EPO directly increases muscle strength. Correction: EPO increases oxygen-carrying capacity, so its main performance benefit is in endurance, not maximal strength.
• Misunderstanding: EPO is safe because it is a natural hormone. Correction: raising red blood cell count increases blood viscosity and the risk of clots, stroke and heart attack.
• Misunderstanding: EPO works immediately. Correction: it stimulates red blood cell production over time, so the effect develops gradually.
• Misunderstanding: EPO improves performance in all sports equally. Correction: the benefit is greatest in endurance events where oxygen delivery limits performance.
• Thinking anabolic steroids are the same as stimulants: they are hormones used mainly for muscle growth and recovery, not for immediate alertness.
• Believing steroids are safe if taken under medical supervision: non-prescribed use for performance is illegal and carries serious health risks.
• Assuming only male athletes use them: female athletes also use them, and females face masculinisation effects.
• Confusing anabolic effects with catabolic effects: anabolic means building tissue, not breaking it down.
• Stating that beta blockers are banned in all sports: WADA only bans them in specific precision sports where they offer a distinct advantage.
• Thinking beta blockers improve endurance: they reduce heart rate and cardiac output, which actually limits aerobic performance.
• Confusing beta blockers with stimulants: beta blockers calm the body and reduce arousal, whereas stimulants increase it.
• Listing only negative implications and ignoring positives. Correction: the question asks for both positive and negative, so include at least one positive for the sport and one for the performer.
• Confusing implications for the sport with implications for the performer. Correction: separate the two clearly, for example a sponsorship loss affects the sport, while a ban affects the performer.
• Using vague examples without naming a sport or performer. Correction: apply each implication to a specific context, such as athletics or cycling, and explain the effect.
• Failing to explain how the implication affects the sport or performer. Correction: for each point, state the implication and then explain the consequence.
• Confusing EPO with anabolic steroids. Correction: EPO increases red blood cell production, while anabolic steroids increase muscle protein synthesis.
• Thinking beta-blockers increase heart rate. Correction: beta-blockers decrease heart rate and reduce tremor.
• Assuming diuretics improve performance by increasing hydration. Correction: diuretics cause fluid loss and can impair performance through dehydration.
• Believing all drugs have the same physiological effect. Correction: each drug class has a specific adaptation, such as muscle growth, oxygen transport or tremor reduction.
• Listing only physiological gains such as increased muscle mass or oxygen transport; the statement asks for social and psychological rewards, so those gains must be reframed as confidence, status or approval.
• Treating all rewards as belonging to the performer; rewards for the sport itself, such as higher standards and greater spectator interest, must also be recognised.
• Assuming rewards are only financial; money is one social or commercial reward, but praise, selection, confidence and reduced anxiety are equally valid.
• Confusing psychological with social rewards; confidence and anxiety control are internal, whereas praise, media attention and sponsorship come from other people.
• Listing only immediate effects such as raised blood pressure; future consequences such as heart disease, infertility and dependence must also be recognised.
• Assuming all drugs carry identical risks; anabolic steroids, stimulants, diuretics and narcotic analgesics each have distinct short- and long-term dangers.
• Treating health harm as purely physical; psychological consequences such as depression, aggression and dependence are also part of the negative impact.
• Believing that stopping use removes all risk; some damage, such as organ or cardiovascular change, can persist after the athlete stops.
• Misunderstanding: only the performer is affected. Correction: the sport also suffers through damaged reputation, lost sponsorship and reduced trust.
• Misunderstanding: psychological effects are limited to guilt. Correction: they can include anxiety, depression, loss of identity and fear of detection.
• Misunderstanding: all doping bans are the same length. Correction: sanctions vary by substance, level of competition and whether it is a repeat offence.
• Misunderstanding: social repercussions only affect the performer's family. Correction: they extend to teammates, coaches, fans, sponsors and the wider sport.
• Misunderstanding: testing alone is enough to eliminate doping. Correction: testing must be combined with education, sanctions and international cooperation.
• Misunderstanding: only urine samples are used. Correction: blood samples and biological passports are also used.
• Misunderstanding: athletes can be tested only at competitions. Correction: out-of-competition and random testing are key strategies.
• Misunderstanding: sanctions are the same for all offences. Correction: sanctions vary by substance, level of competition and whether it is a repeat offence.
• Listing arguments without explaining why they matter. Correction: develop each point by linking it to fairness, health, or the spirit of sport.
• Treating all drug taking as identical. Correction: distinguish between performance-enhancing drugs, recreational drugs, and legitimate therapeutic use.
• Ignoring arguments against testing. Correction: include cost, privacy, false positives, and unequal testing as genuine counter-arguments.
• Writing a one-sided answer. Correction: give both sides and reach a balanced conclusion.
• Memorising the exact steps of sample collection. Correction: focus on arguments for and against testing, not the procedure.
• Learning laboratory analysis methods in detail. Correction: understand the purpose and ethical debates around testing instead.
• Confusing testing procedures with testing arguments. Correction: the specification excludes procedures but includes arguments for and against testing.
• Spending revision time on chain-of-custody paperwork. Correction: use that time to prepare balanced evaluation of drug taking and testing.
• Misconception: All drugs in sport are illegal. Correction: Some substances are only banned in competition (e.g., stimulants), while others are banned at all times (e.g., anabolic steroids).
• Misconception: Drug testing is foolproof. Correction: Athletes use masking agents, designer drugs, and micro-dosing to evade detection, so testing has limitations.
• Misconception: Only professional athletes dope. Correction: Doping occurs at all levels, including amateur and youth sport, often due to pressure to win or improve body image.
