(a) Name two categories of illegal performance-enhancing drugs used in sport. (2)
(b) State two ways in which technology (sports clothing or equipment) has impacted sports performance. (2)
Show answer & marking scheme

Worked solution

(a) Illegal performance-enhancing drugs in sport fall into several recognised categories: anabolic steroids, which promote muscle growth and strength; stimulants, which increase alertness and delay fatigue; erythropoietin (EPO) and other blood-doping agents, which increase red blood cell count and so oxygen-carrying capacity; beta blockers, which can steady the hands/reduce tremor in precision sports; and diuretics, sometimes used to mask other drugs or achieve rapid weight loss. Any two distinct, valid categories are acceptable. (b) Technological developments in sports clothing and equipment can have a significant impact on performance: lighter, more aerodynamic or hydrodynamic clothing (for example compression garments or specialist swimsuits) can reduce air or water resistance, improving speed; and advances in equipment design, such as carbon-plated running shoes that improve energy return, or improved materials in rackets, bikes or javelins, can improve power transfer, comfort or reduce injury risk, all of which can enhance performance. Final answer: (a) any two of anabolic steroids, stimulants, EPO/blood-doping agents, beta blockers, diuretics; (b) any two valid technological impacts, e.g. aerodynamic/hydrodynamic clothing reducing resistance, and improved equipment design improving energy return/power transfer.

Marking scheme

(a) 1 mark each for any two valid categories of illegal drug (accept named examples, e.g. steroids, EPO, stimulants, beta blockers, diuretics). Max 2. (b) 1 mark each for any two valid, distinct ways technology has impacted performance, with a brief correct description. Max 2.
Question 2 · Short Answer & Definitions (1-4 marks)
4 marks
(a) State two strategies used by sports governing bodies to counter illegal drug use in sporting performance. (2)
(b) Explain one reason an athlete might still choose to use illegal drugs despite these strategies being in place. (2)
Show answer & marking scheme

Worked solution

(a) Governing bodies use a range of strategies to counter illegal drug use, including random and out-of-competition drug testing (so athletes cannot simply avoid using banned substances only near competition time), athlete education programmes about the health risks and rules surrounding banned substances, and imposing significant sanctions, such as competition bans, suspensions, or the stripping of medals and titles, on athletes who test positive, intended to act as a deterrent. Maintaining and regularly updating a published list of banned substances (such as the World Anti-Doping Agency's prohibited list) also gives athletes and coaches clarity on what is not permitted. Any two distinct, valid strategies are acceptable. (b) Despite these strategies, an athlete might still choose to use illegal drugs because the perceived potential rewards, such as improved performance leading to medals, prize money, sponsorship deals or career advancement, may be seen by the athlete as outweighing the risk of being caught and sanctioned, especially if they believe detection methods can be evaded (e.g. through timing use around testing windows) or if they suspect (rightly or wrongly) that rival competitors are also doping and feel pressure to do the same to remain competitive. Final answer: (a) any two of random/out-of-competition testing, athlete education, bans/sanctions, published banned-substance lists; (b) e.g. perceived reward outweighs perceived risk of detection, or a belief that competitors are also doping.

Marking scheme

(a) 1 mark each for any two valid strategies used by governing bodies. Max 2. (b) 2 marks for a valid reason with a clear, linked explanation (1 mark for a bare valid reason with no explanation). Max 2.
Question 3 · Short Answer & Definitions (1-4 marks)
3 marks
(a) State whether a tennis serve is best classified as an open or closed skill, using the skill continuum. (1)
(b) Give two reasons for your answer. (2)
Show answer & marking scheme

Worked solution

(a) A tennis serve is classified as a closed skill on the open/closed skill continuum. (b) This classification is justified because the environment in which the skill is performed is stable and predictable: the server controls when to begin the action, tosses the ball themselves, and the court, net and rules do not change or move unpredictably during the serve, unlike, for example, a rugby player having to react to constantly changing opponent positions. It is also largely self-paced, meaning the performer decides when to initiate the movement, rather than having to react immediately to an external, unpredictable stimulus, which is characteristic of closed rather than open skills. Final answer: (a) closed skill; (b) the environment is stable/predictable and the server controls the timing (self-paced), both characteristic of closed skills.

Marking scheme

(a) 1 mark for 'closed skill'. (b) 1 mark each for any two valid, distinct justifying reasons (e.g. stable/predictable environment, self-paced/performer controls timing). Max 2.
Question 4 · Short Answer & Definitions (1-4 marks)
4 marks
(a) State two short-term responses of the cardiovascular system to a single bout of exercise. (2)
(b) State two long-term adaptations of the cardiovascular system to regular exercise training. (2)
Show answer & marking scheme

Worked solution

(a) During a single bout of exercise, the cardiovascular system responds immediately (short-term) in several ways: heart rate increases to deliver more oxygenated blood to working muscles; stroke volume (the volume of blood ejected per heartbeat) increases; the resulting cardiac output (heart rate x stroke volume) increases; and blood flow is redistributed via vasodilation of vessels supplying the working muscles and vasoconstriction of vessels supplying less essential organs (such as the digestive system) at that time — a process known as vascular shunting. Any two distinct, valid short-term responses are acceptable. (b) With regular exercise training over time, the cardiovascular system adapts (long-term) in ways that improve its efficiency: the heart increases in size (cardiac hypertrophy, particularly of the left ventricle), allowing it to eject more blood per beat; resting and maximal stroke volume increase; capillarisation (the density of capillaries around muscle fibres) increases, improving oxygen and nutrient delivery/waste removal; and resting heart rate decreases (bradycardia), reflecting the heart's improved efficiency at rest. Any two distinct, valid long-term adaptations are acceptable. Final answer: (a) any two of increased heart rate, stroke volume, cardiac output, or vascular shunting (vasodilation/vasoconstriction); (b) any two of cardiac hypertrophy, increased stroke volume, increased capillarisation, bradycardia.

Marking scheme

(a) 1 mark each for any two valid short-term cardiovascular responses. Max 2. (b) 1 mark each for any two valid long-term cardiovascular adaptations. Max 2.
Question 5 · Short Answer & Definitions (1-4 marks)
4 marks
(a) Name the three stages of learning in Fitts and Posner's model, in order. (3)
(b) State one characteristic of a performer in the autonomous stage of learning. (1)
Show answer & marking scheme

Worked solution

(a) Fitts and Posner's model describes three stages a learner progresses through when acquiring a skill, in order: the cognitive stage (the performer is a beginner, thinking carefully about what to do and making frequent, gross errors); the associative stage (the performer practises, refining the skill, with performance becoming more consistent and errors becoming fewer and more minor); and the autonomous stage (the skill has become largely automatic). (b) In the autonomous stage, the performer can execute the skill with little or no conscious thought about the mechanics of the movement itself, performing it smoothly, consistently and efficiently; this frees up the performer's attention to focus on other aspects of performance, such as reading the game, tactics, or the position of opponents/teammates, rather than the basic technique. Final answer: (a) cognitive, associative, autonomous; (b) e.g. the skill is performed automatically/fluently, freeing attention for tactical awareness.

Marking scheme

(a) 1 mark each for the three stages in the correct order (cognitive, associative, autonomous); no credit if the order is incorrect. Max 3. (b) 1 mark for a valid characteristic of the autonomous stage. Max 1.
Question 6 · Short Answer & Definitions (1-4 marks)
3 marks
(a) Define the term 'tidal volume'. (1)
(b) State how tidal volume typically changes during exercise compared with at rest, and explain why this change occurs. (2)
Show answer & marking scheme

Worked solution

(a) Tidal volume is defined as the volume of air that moves into or out of the lungs during a single, normal breath (i.e. one breath at rest, not a forced maximal breath). (b) During exercise, tidal volume increases substantially above its resting value; this occurs because the working muscles have a greater demand for oxygen to support increased aerobic respiration, and produce more carbon dioxide as a waste product that needs to be removed; taking deeper breaths (a larger tidal volume) increases the amount of air, and therefore the amount of oxygen brought in and carbon dioxide removed, with each breath, helping meet the increased gas exchange demands of the exercising body. Final answer: (a) the volume of air breathed in/out in one normal breath; (b) tidal volume increases during exercise, to increase the oxygen delivered and carbon dioxide removed per breath, meeting the muscles' increased demand.

Marking scheme

(a) 1 mark for a correct definition. Max 1. (b) 1 mark for correctly stating tidal volume increases; 1 mark for a correct, linked explanation (increased oxygen demand/carbon dioxide removal). Max 2.
Question 7 · Short Answer & Definitions (1-4 marks)
4 marks
(a) Name the muscle primarily responsible for inspiration at rest. (1)
(b) Name two additional (accessory) muscles used to assist inspiration during exercise. (2)
(c) State what happens to the rate and depth of breathing during exercise, compared with at rest. (1)
Show answer & marking scheme

Worked solution

(a) At rest, inspiration is primarily driven by contraction of the diaphragm, a dome-shaped muscle beneath the lungs which flattens and moves downward as it contracts, increasing the volume of the thoracic cavity and drawing air into the lungs. (b) During exercise, when a greater volume of air needs to be moved more quickly, accessory muscles assist inspiration by helping to further expand the thoracic cavity; these include the external intercostal muscles (which help raise the ribs), and muscles such as the sternocleidomastoid, scalenes, or pectoralis minor, which can help lift the ribcage further during more forceful breathing. Any two valid accessory muscles are acceptable. (c) During exercise, both the rate of breathing (the number of breaths per minute) and the depth of breathing (the tidal volume per breath) increase, together increasing the total volume of air (and therefore oxygen) moved into and out of the lungs per minute (minute ventilation), to meet the body's increased demand for gas exchange. Final answer: (a) diaphragm; (b) any two of external intercostals, sternocleidomastoid, scalenes, pectoralis minor; (c) both rate and depth of breathing increase.

Marking scheme

(a) 1 mark for diaphragm. (b) 1 mark each for any two valid accessory inspiratory muscles. Max 2. (c) 1 mark for correctly stating both rate and depth increase. Max 1.
Question 8 · Short Answer & Definitions (1-4 marks)
2 marks
State one difference between a concentric muscle contraction and an eccentric muscle contraction. (2)
Show answer & marking scheme

Worked solution

A concentric contraction occurs when a muscle shortens while generating force, actively moving a joint through a range of motion against a resistance, for example the biceps brachii shortening during the lifting (upward) phase of a bicep curl. An eccentric contraction occurs when a muscle lengthens while still generating force (under tension), typically acting to control or decelerate a movement, for example the biceps brachii lengthening under control during the lowering (downward) phase of a bicep curl, rather than simply relaxing. The key difference is therefore the direction of length change of the muscle (shortening versus lengthening) while it remains active and producing force. Final answer: concentric = muscle shortens while producing force; eccentric = muscle lengthens while producing force (under tension), e.g. controlling a lowering movement.

Marking scheme

2 marks for a clear, correct statement of the difference (muscle shortens under tension in a concentric contraction versus lengthens under tension in an eccentric contraction), ideally with a linked sporting example. 1 mark for a partially correct or one-sided answer. Max 2.
Question 9 · Short Answer & Definitions (1-4 marks)
3 marks
Name the type of synovial joint found at each of the following locations:
(a) the shoulder (1)
(b) the elbow (1)
(c) the wrist (radiocarpal joint) (1)
Show answer & marking scheme

Worked solution

(a) The shoulder (glenohumeral) joint is a ball and socket joint, allowing movement in multiple planes (flexion/extension, abduction/adduction, rotation, and circumduction). (b) The elbow joint is a hinge joint, allowing movement primarily in one plane (flexion and extension only). (c) The wrist (radiocarpal) joint is a condyloid joint, which allows movement in two planes (flexion/extension and abduction/adduction) but not rotation. Final answer: (a) ball and socket; (b) hinge; (c) condyloid.

Marking scheme

1 mark each for the three correctly named joint types. Max 3.
Question 10 · Structured Anatomical Movement Analysis (4 marks each)
4 marks
During the upward (lifting) phase of a bicep curl, the elbow joint flexes.
(a) State the joint action occurring at the elbow. (1)
(b) Name the agonist (prime mover) muscle responsible for this action. (1)
(c) State the type of contraction the agonist muscle performs during this phase. (1)
(d) Name the antagonist muscle for this action. (1)
Show answer & marking scheme

Worked solution

(a) During the upward phase of a bicep curl, the angle at the elbow joint decreases, which is the joint action of flexion. (b) The muscle primarily responsible for producing this flexion (the agonist, or prime mover) is the biceps brachii, located on the front of the upper arm. (c) As the biceps brachii shortens to produce the lifting/flexing movement while generating force, it performs a concentric contraction. (d) The antagonist muscle, which relaxes (and lengthens) to allow the movement, and which would produce the opposite action (extension) if it contracted instead, is the triceps brachii, located on the back of the upper arm. Final answer: (a) flexion; (b) biceps brachii; (c) concentric; (d) triceps brachii.

Marking scheme

1 mark each for the four correct answers: (a) flexion; (b) biceps brachii; (c) concentric; (d) triceps brachii. Max 4.
Question 11 · Structured Anatomical Movement Analysis (4 marks each)
4 marks
During the upward (push) phase of a calf raise, plantar flexion occurs at the ankle joint.
(a) Define 'plantar flexion'. (1)
(b) Name the agonist muscle group responsible for this action. (1)
(c) State the type of contraction the agonist performs during this phase. (1)
(d) Name the antagonist muscle for this action. (1)
Show answer & marking scheme

Worked solution

(a) Plantar flexion is the joint action at the ankle in which the foot is pointed downward (away from the body/shin), as when standing up onto the toes or pointing the toes, moving the sole of the foot away from the front of the leg. (b) The agonist muscle group producing plantar flexion is the calf musculature, primarily the gastrocnemius (assisted by the soleus), which attaches via the Achilles tendon to the heel. (c) As the gastrocnemius shortens to pull the heel upward and produce the plantar flexion movement while generating force, it performs a concentric contraction. (d) The antagonist muscle, which would produce the opposite action (dorsiflexion) if it contracted, and which lengthens to allow plantar flexion to occur, is the tibialis anterior, located on the front of the shin. Final answer: (a) pointing the foot/toes downward, away from the shin; (b) gastrocnemius (and soleus); (c) concentric; (d) tibialis anterior.

Marking scheme

(a) 1 mark for a correct definition. (b) 1 mark for gastrocnemius (accept soleus, or 'calf muscles'). (c) 1 mark for concentric. (d) 1 mark for tibialis anterior. Max 4.
Question 12 · Structured Anatomical Movement Analysis (4 marks each)
4 marks
A gymnast performs a cartwheel, which involves abduction of the shoulder joint as the arms are raised sideways above the head.
(a) Name the type of synovial joint at the shoulder. (1)
(b) Define 'abduction'. (1)
(c) State the joint action that is the direct opposite of abduction. (1)
(d) Name a different sporting example (other than a cartwheel) that demonstrates circumduction at a joint. (1)
Show answer & marking scheme

Worked solution

(a) The shoulder (glenohumeral) joint is a ball and socket joint. (b) Abduction is defined as the movement of a limb or body part away from the midline (centre line) of the body, for example raising the arm out sideways from the body, as occurs during a cartwheel. (c) The direct opposite joint action is adduction, movement of a limb or body part back towards the midline of the body. (d) Circumduction is a circular movement of a limb, combining flexion, extension, abduction and adduction in sequence, tracing a cone shape; a clear sporting example, other than a cartwheel, is a bowler's arm moving through a full circular arc during a cricket bowling action, or a swimmer's arm moving in a large circular motion during front crawl. Final answer: (a) ball and socket; (b) movement away from the midline of the body; (c) adduction; (d) e.g. a cricket bowler's circular arm swing, or a front-crawl swimmer's arm action.

Marking scheme

(a) 1 mark for ball and socket joint. (b) 1 mark for a correct definition. (c) 1 mark for adduction. (d) 1 mark for a valid, distinct sporting example clearly demonstrating a full circular (circumduction) movement. Max 4.
Question 13 · Short Application & Outline (5-6 marks)
5 marks
Outline how gaseous exchange takes place across the respiratory surfaces (alveoli) in the lungs. (5)
Show answer & marking scheme

Worked solution

Gaseous exchange occurs by simple diffusion across the walls of the alveoli and the surrounding pulmonary capillaries, and this process is supported by several structural features. The lungs contain millions of alveoli, giving a very large total surface area over which exchange can take place. The walls of both the alveoli and the capillaries are extremely thin (each only one cell thick), which minimises the diffusion distance/pathway that gas molecules must cross, allowing exchange to happen quickly. The alveolar surface is kept moist, which allows oxygen and carbon dioxide to dissolve before diffusing across the membrane. The alveoli are surrounded by a dense network of capillaries, and continuous blood flow through these capillaries (along with continuous ventilation of the alveoli) helps maintain a steep concentration gradient for both gases. Using this gradient, oxygen diffuses from the alveolar air, where its concentration is relatively high, into the blood in the pulmonary capillaries, where its concentration is relatively low (having been used up by the body's tissues); at the same time, carbon dioxide, produced by cellular respiration in the body's tissues, diffuses from the blood, where its concentration is relatively high, into the alveolar air, where its concentration is relatively low, ready to be exhaled. Final answer: gaseous exchange relies on a large surface area, thin exchange surfaces, a moist alveolar lining, a rich capillary network maintaining a concentration gradient, and diffusion of oxygen into the blood and carbon dioxide out of the blood down their respective concentration gradients.

Marking scheme

1 mark each for any five of the following valid points, up to a maximum of 5: large surface area (many alveoli); thin walls/short diffusion distance (alveolar and capillary walls one cell thick); moist alveolar surface (allows gases to dissolve); rich capillary network maintaining a concentration gradient; oxygen diffuses from alveoli (high concentration) into blood (low concentration); carbon dioxide diffuses from blood (high concentration) into alveoli (low concentration); reference to diffusion occurring down a concentration gradient. Max 5.
Question 14 · Short Application & Outline (5-6 marks)
6 marks
Outline the process of vascular shunting (the redistribution of blood flow) that occurs during exercise, referring to vasoconstriction and vasodilation. (6)
Show answer & marking scheme

Worked solution

Vascular shunting is the process by which the distribution of blood flow around the body is altered to match the changing demands of different tissues, and it is controlled by the vasomotor centre in the brain, which regulates the diameter of arterioles supplying different organs and tissues. During exercise, the body's priority shifts towards supplying the working skeletal muscles (and the heart and lungs) with the oxygen and nutrients they now need in much greater quantity; vasodilation (widening) of the arterioles supplying these working muscles occurs, reducing resistance to blood flow and allowing significantly more blood to reach them. At the same time, vasoconstriction (narrowing) of the arterioles supplying tissues and organs with reduced priority during exercise, such as the digestive system, skin, and kidneys, reduces blood flow to these areas, since their demand for blood is lower during physical activity than at rest (for example, digestion is not a priority during intense exercise). Because cardiac output, while increased during exercise, is still limited, this combination of vasodilation of working-muscle arterioles and vasoconstriction of non-priority-area arterioles ensures that a much greater proportion of the available blood supply is redirected to where it is most needed, improving the delivery of oxygen and nutrients to the working muscles and helping to delay the onset of fatigue. Final answer: vascular shunting redirects blood flow during exercise via vasodilation of arterioles supplying working muscles (and heart/lungs) and vasoconstriction of arterioles supplying lower-priority areas (e.g. digestive system, skin, kidneys), controlled by the vasomotor centre, maximising oxygen/nutrient delivery to working muscles from the available cardiac output.

Marking scheme

1 mark each for any six of the following valid points, up to a maximum of 6: correct definition/purpose of vascular shunting (redistribution of blood flow to match demand); reference to control by the vasomotor centre; vasodilation of arterioles supplying working muscles; vasoconstriction of arterioles supplying non-priority areas; named examples of reduced-priority areas (e.g. digestive system, skin, kidneys); explanation that cardiac output is limited, so redistribution maximises supply to muscles; explanation of the resulting benefit (improved oxygen/nutrient delivery, delayed fatigue). Max 6.
Question 15 · Extended Written QWC Essays (8, 10, 12, 16 marks)
8 marks
Discuss how a coach could use knowledge of the three stages of learning (cognitive, associative and autonomous) and appropriate teaching styles to improve a performer's skill acquisition.

The quality of your written communication is assessed in this question. (8)
Show answer & marking scheme

Worked solution

A strong answer explains that a performer in the cognitive stage is a beginner, trying to understand the basic requirements of the skill and making frequent, often large errors; at this stage, a coach should keep instructions simple and clear, provide accurate demonstrations, and use a largely command style of teaching (where the coach makes most of the decisions and the performer closely replicates instructions), along with frequent, simple feedback focused on the most fundamental errors, since the performer is not yet able to self-correct effectively. As the performer moves into the associative stage, they have grasped the basic pattern of the skill and refine it through repeated practice, with performance becoming more consistent and errors becoming smaller and less frequent; here, a coach can begin to use more reciprocal teaching styles (for example, pairing performers to observe and give each other feedback against set criteria) or increase practice-style opportunities, and feedback can become more detailed and specific, helping the performer fine-tune technique. In the autonomous stage, the skill has become largely automatic, freeing the performer's attention for tactical, strategic or game-related decisions; a coach can now appropriately use discovery or problem-solving teaching styles, setting more complex, game-realistic practice situations and challenges rather than closely directing every action, since the performer is capable of adapting the skill to varied situations and benefits more from feedback focused on outcomes, decision-making and performance under pressure rather than basic technique. By correctly matching the teaching style and type/frequency of feedback to the performer's current stage of learning, rather than using the same approach throughout, a coach ensures that practice remains appropriately challenging and instructions remain appropriately pitched, which supports faster, more effective progress through the stages of learning and ultimately better skill acquisition. Final answer: matching command-style teaching and simple, frequent feedback to the cognitive stage, more reciprocal/practice styles and detailed feedback to the associative stage, and discovery/problem-solving styles with outcome-focused feedback to the autonomous stage, allows a coach to support a performer's skill acquisition appropriately at each stage of learning.

Question 16 · Extended Written QWC Essays (8, 10, 12, 16 marks)
10 marks
Discuss the short-term responses and long-term adaptations of the cardiovascular and respiratory systems to exercise.

The quality of your written communication is assessed in this question. (10)
Show answer & marking scheme

Worked solution

A strong answer addresses both systems, distinguishing clearly between immediate (short-term) responses to a single bout of exercise and adaptations that develop over time (long-term) with repeated training. For the cardiovascular system, short-term responses to exercise include an increase in heart rate, an increase in stroke volume, and the resulting increase in cardiac output, all of which increase the rate at which oxygenated blood is delivered to working muscles; vascular shunting also occurs, with vasodilation of vessels supplying working muscles and vasoconstriction of vessels supplying lower-priority areas, redirecting blood flow to where it is most needed. With long-term training, the cardiovascular system adapts: the heart increases in size (cardiac hypertrophy, particularly of the left ventricle), enabling a greater resting and maximal stroke volume; capillarisation around muscle fibres increases, improving oxygen and nutrient delivery and waste removal; maximal cardiac output and VO2 max increase, improving the capacity to deliver and use oxygen; and resting heart rate decreases (bradycardia), reflecting the heart's improved efficiency, since a larger, stronger heart can maintain the same resting cardiac output with fewer beats. For the respiratory system, short-term responses to exercise include an increase in the rate and depth of breathing (increasing minute ventilation), supporting increased gas exchange to meet the muscles' greater oxygen demand and carbon dioxide production. With long-term training, the respiratory muscles (such as the diaphragm and intercostals) become stronger and more efficient, which can improve the mechanics and efficiency of breathing during exercise, supporting sustained increases in ventilation with less relative effort/fatigue of the respiratory muscles themselves. Overall, these short-term responses allow the body to immediately meet the increased demands of a single exercise bout, while the long-term adaptations, developed through regular training, improve the body's overall capacity to deliver and use oxygen, supporting improved endurance performance and delaying the onset of fatigue over time. Final answer: cardiovascular short-term responses (increased heart rate, stroke volume, cardiac output, vascular shunting) and long-term adaptations (cardiac hypertrophy, increased stroke volume/capillarisation/cardiac output/VO2 max, bradycardia), together with respiratory short-term responses (increased rate/depth of breathing) and long-term adaptations (stronger, more efficient respiratory muscles), together explain how the body immediately copes with, and progressively adapts to, the demands of exercise.

Using a named sporting activity, classify and analyse the skills required using the skill continuum (open/closed, discrete/serial/continuous, gross/fine, self-paced/externally paced), and discuss how a coach could use this classification to inform practice and training methods.

The quality of your written communication is assessed in this question. (12)
Show answer & marking scheme

Worked solution

A strong answer selects a specific sporting activity and skill (for example, a basketball free throw, or football dribbling under pressure) and classifies it clearly on each of the four continua with justified reasoning. Taking basketball as an example: a free throw is a closed skill (performed in a stable, predictable environment, with the performer controlling the timing) but dribbling past a defender in open play is an open skill (the environment, including the defender's movements, is unpredictable and constantly changing, requiring the performer to adapt); a free throw is discrete (it has a clear beginning and end, e.g. one shooting action), whereas continuous dribbling down the court has no natural beginning or end point until the player chooses to stop, and a set play involving several linked actions (e.g. dribble, pass, cut) would be serial; shooting technique itself involves fine motor control (precise hand/finger movement for ball release) while the overall movement of running and jumping involves gross motor skills using large muscle groups; and a free throw is self-paced (the shooter decides when to begin) whereas reacting to a defender's movement while dribbling is externally paced (timing is dictated by an external stimulus, the opponent). A coach can use this classification directly to inform how practice is designed: for the closed, self-paced free throw, repetitive blocked practice in a stable, unopposed environment is appropriate to groove consistent technique; but for the open, externally paced skill of dribbling past a defender, practice should progressively introduce unpredictable elements (for example practising against a live, reactive defender, or varied random practice rather than a single fixed pattern), since practising this skill only in a closed, unopposed drill would not prepare the performer for the variability of a real defender and would transfer poorly to competitive performance. Similarly, a serial skill made up of several linked actions may benefit from part-practice of the individual components before they are combined into the whole serial sequence, whereas a genuinely continuous skill is generally better practised as a whole, since breaking it into parts can disrupt its natural rhythm. By correctly identifying where a skill sits on each continuum, a coach ensures that the practice methods used, whether blocked or variable, whole or part, stable or unpredictable, are well matched to the true demands of the skill, which improves the effectiveness of practice and the extent to which improvements transfer into competitive performance. Final answer: a specific skill (e.g. a basketball free throw versus dribbling past a defender) can be classified on the open/closed, discrete/serial/continuous, gross/fine and self-paced/externally-paced continua, and a coach should design practice methods (e.g. blocked versus variable/random practice, whole versus part practice, stable versus increasingly unpredictable practice conditions) that match this classification, to maximise the effectiveness of practice and its transfer to competitive performance.

Worked solution

A strong answer explains that illegal drug use can have significant implications for sports performance: substances such as anabolic steroids, stimulants, or erythropoietin (EPO) can directly enhance performance, for example by increasing muscle mass and strength, delaying fatigue, or increasing oxygen-carrying capacity, giving athletes who use them an unfair advantage over those who do not; however, these implications extend beyond simple performance gain, since illegal drug use also carries serious health risks to the athlete (for example cardiovascular strain, hormonal disruption, or dependency), can end an athlete's career and reputation if detected (through bans, disqualification, and loss of sponsorship), and more broadly undermines the fairness, integrity and public trust in sport as a whole, potentially discouraging clean athletes and damaging spectator confidence. Turning to technology, developments in sports clothing and equipment (for example lighter, more aerodynamic clothing, improved footwear, or advanced equipment materials) can also have significant implications for performance, improving speed, power transfer, comfort or safety; unlike illegal drugs, these developments are generally legal and can be seen as a legitimate part of sporting progress, but they can still raise concerns about fairness if access to the most advanced (and often expensive) technology is unequal between athletes, teams or nations, effectively creating an advantage based on resources rather than pure athletic ability — a milder but still relevant fairness concern compared with doping. Evaluating governing bodies' strategies to counter illegal drug use, such as random and out-of-competition testing, athlete education, published banned-substance lists, and sanctions/bans for those caught: these strategies have real strengths, since testing and the threat of significant sanctions act as a meaningful deterrent for many athletes, and education helps ensure athletes understand what is and is not permitted, reducing accidental breaches. However, these strategies also have limitations: testing technology and detection methods can lag behind new or designer drugs, meaning some doping may go undetected for a period; testing (particularly comprehensive, frequent out-of-competition testing) is expensive and resource-intensive, and may not be applied equally across all sports, countries or levels of competition, potentially creating an uneven playing field in enforcement itself; and ultimately, strategies rely on athletes (and sometimes support staff) choosing to comply, meaning determined individuals may still find ways to circumvent the system, at least temporarily. A well-evidenced judgement should weigh these points together, for example concluding that governing bodies' strategies are a necessary and broadly effective deterrent and detection system that meaningfully reduces (though cannot entirely eliminate) illegal drug use, and that continued investment in testing technology, international consistency of enforcement, and athlete education remain important to keep pace with evolving methods of doping. Final answer: illegal drugs can meaningfully enhance performance but carry serious health, legal, and integrity-of-sport implications; technological developments in clothing/equipment can also improve performance and are generally legal, though can raise fairness concerns linked to unequal access; and governing bodies' strategies (testing, education, sanctions) provide an important, broadly effective but imperfect deterrent, limited by the cost/reach of testing and the evolving nature of doping methods.

Marking scheme

Levels of response, assessing Quality of Written Communication. Band 3 (11-16 marks): comprehensive, accurate, balanced discussion of the implications of both drug taking AND technological developments on performance, together with a genuinely evaluative (not merely descriptive) assessment of governing-body strategies, weighing strengths and limitations to reach a justified overall judgement; excellent use of specialist terminology and a clear, coherent, well-organised structure throughout. Band 2 (6-10 marks): reasonable coverage of at least two of the three required areas (drug-taking implications, technology implications, evaluation of strategies) with some balance and detail, adequate terminology and organisation, but limited or underdeveloped evaluation/judgement. Band 1 (1-5 marks): basic, general, largely descriptive statements covering at most one area in any depth, little or no evaluation, weak organisation/terminology. Band 0 (0 marks): no creditable response. Indicative content includes: performance-enhancing effects of illegal drugs (e.g. increased muscle mass/endurance, reduced tremor); health, legal/career and integrity-of-sport implications of doping; performance and safety benefits of technological developments in clothing/equipment; fairness concerns linked to unequal access to technology; governing-body strategies — random/out-of-competition testing, athlete education, banned-substance lists, sanctions/bans; strengths of these strategies (deterrence, clarity); limitations (detection lag behind new substances, cost/resource constraints, inconsistent global enforcement, reliance on compliance).
