Question 1Physical Education Studies

Which energy system is the primary contributor of ATP during a maximal 100-metre sprint lasting about 10 seconds?

  1. The ATP-PC (phosphagen) system Correct answer.
  2. The aerobic glycolysis system
  3. The aerobic system
  4. The lactic acid system

Explanation

Efforts lasting roughly 6 to 10 seconds at maximal intensity rely predominantly on stored ATP and phosphocreatine, which can resynthesise ATP extremely rapidly without oxygen. This ATP-PC system fatigues quickly because phosphocreatine stores are small. The lactic system contributes but becomes dominant slightly later, and the aerobic system is too slow to be the main source.

Question 2Physical Education Studies

During a marathon, a runner's body mainly resynthesises ATP through which process?

  1. Lactate fermentation in the cytoplasm
  2. Rapid phosphocreatine breakdown
  3. The alactic anaerobic pathway
  4. Oxidative phosphorylation in the mitochondria Correct answer.

Explanation

Prolonged endurance activity such as a marathon is supported almost entirely by the aerobic system, where carbohydrate and fat are oxidised in the mitochondria to produce large amounts of ATP. Oxidative phosphorylation yields the greatest total ATP per substrate molecule and can be sustained for hours. The other pathways are anaerobic and cannot maintain output over such a duration.

Question 3Physical Education Studies

Which muscle fibre type is best suited to explosive, high-force movements such as a vertical jump?

  1. Type IIx fast-twitch fibres Correct answer.
  2. Type I slow-twitch fibres
  3. Cardiac muscle fibres
  4. Smooth muscle fibres

Explanation

Type IIx fibres have a high myosin ATPase activity, large motor neuron innervation and a fast contraction speed, allowing rapid force production for explosive actions. They fatigue quickly because they rely on anaerobic metabolism and have fewer mitochondria. Type I fibres contract slowly and are suited to endurance rather than power.

Question 4Physical Education Studies

Which structure connects muscle to bone and transmits the force generated by contraction?

  1. A tendon Correct answer.
  2. Cartilage
  3. Fascia
  4. A ligament

Explanation

Tendons are dense regular connective tissue that attach skeletal muscle to bone, transmitting the tension produced by the muscle to create joint movement. Ligaments instead join bone to bone, cartilage provides smooth articular surfaces, and fascia is a connective sheet surrounding and separating muscles.

Question 5Physical Education Studies

Which joint action occurs when the elbow angle decreases as the forearm is drawn toward the upper arm?

  1. Abduction
  2. Rotation
  3. Extension
  4. Flexion Correct answer.

Explanation

Flexion is the decrease in the angle at a joint, which is exactly what happens when the elbow bends and the forearm moves toward the upper arm. Extension is the opposite action, increasing the joint angle. Abduction and rotation describe movement away from the midline and turning about a long axis respectively.

Question 6Physical Education Studies

A netballer lands from a jump and bends the knees to slow down. Which biomechanical principle best explains why bending the knees reduces the force on the body?

  1. Decreasing the mass of the body reduces the force
  2. Increasing the time over which the body decelerates reduces the force Correct answer.
  3. Increasing the impulse reduces the force
  4. Reducing the contact area reduces the force

Explanation

Force equals the change in momentum divided by the time over which the change occurs, so lengthening the deceleration time lowers the average force for the same change in momentum. Bending the knees during landing extends the time taken to stop the body. The body's mass does not change, and impulse is the product of force and time, not a cause of reduced force on its own.

Question 7Physical Education Studies

A swimmer pushes off the wall and glides in a streamlined position. Which principle explains why the streamlined shape allows a longer glide?

  1. It increases the swimmer's buoyancy
  2. It reduces the swimmer's weight in the water
  3. It increases the swimmer's momentum at push-off
  4. It reduces the frontal area and therefore the drag force Correct answer.

Explanation

Drag in a fluid increases with the frontal cross-sectional area and the square of velocity, so adopting a streamlined position reduces the area presented to the water and lowers drag. With less drag decelerating the swimmer, the glide is longer. Buoyancy, push-off momentum and weight are not changed by the shape itself.

Question 8Physical Education Studies

Which of the following best describes the principle of specificity in training?

  1. Training must be reduced before competition to allow recovery
  2. Training must vary constantly to prevent boredom
  3. Training must progressively increase the load to keep producing gains
  4. Training adaptations are specific to the type of training performed Correct answer.

Explanation

The specificity principle states that the body adapts to the particular demands imposed on it, so training should mimic the energy systems, muscle groups and movement patterns of the target activity. Progressive overload describes increasing load, tapering describes reducing volume before competition, and variation describes changing training stimuli. Specificity is about matching training to the desired outcome.

Question 9Physical Education Studies

A coach increases a lifter's squat load from 60 kg to 70 kg after several weeks of consistent training. Which training principle is being applied?

  1. Reversibility
  2. Progressive overload Correct answer.
  3. Specificity
  4. Individuality

Explanation

Progressive overload involves gradually increasing the training stimulus, such as load, volume or intensity, so the body continues to adapt beyond its current capacity. Raising the squat load is a direct application of this principle. Reversibility refers to loss of fitness when training stops, specificity to matching training to the goal, and individuality to tailoring programs to the person.

Question 10Physical Education Studies

Which of the following is the most appropriate first-aid response for a suspected ankle sprain sustained during a game?

  1. Apply heat and encourage immediate return to play
  2. Vigorously massage the joint to disperse swelling
  3. Follow the RICER protocol: rest, ice, compression, elevation and referral Correct answer.
  4. Immobilise the joint permanently with a cast

Explanation

The RICER approach reduces bleeding and swelling in the acute phase of a soft-tissue injury: rest limits further damage, ice and compression reduce swelling, elevation aids drainage, and referral ensures proper assessment. Heat, vigorous massage and immediate return to play can worsen bleeding and swelling. Permanent casting is not a first-aid measure.

Question 11Physical Education Studies

Which of the following best describes the role of the antagonist muscle during a movement?

  1. It relaxes and lengthens to allow the agonist to act Correct answer.
  2. It contracts concentrically to produce the movement
  3. It stabilises the joint without any change in length
  4. It generates the majority of the force for the action

Explanation

During a controlled movement the agonist, or prime mover, contracts to produce the action while the antagonist on the opposite side of the joint relaxes and lengthens, a process known as reciprocal inhibition. This allows smooth, coordinated movement. Stabilisers hold a joint steady, and the agonist rather than the antagonist generates the main force.

Question 12Physical Education Studies

A coach wants to improve a team's aerobic capacity in the off-season. Which training method is most appropriate?

  1. Heavy resistance training at three sets of five repetitions
  2. Repeated 5-second maximal sprints with long rests
  3. Continuous running at moderate intensity for 30 to 40 minutes Correct answer.
  4. Static stretching held for 30 seconds per muscle

Explanation

Aerobic capacity is best developed by sustained submaximal work that keeps heart rate elevated for an extended period, allowing the oxidative system to be stressed and adapted. Continuous moderate-intensity running for 30 to 40 minutes meets this requirement. Short maximal sprints train the anaerobic systems, heavy resistance training develops strength, and static stretching develops flexibility.

Question 13Physical Education Studies

Which of the following best explains why a performer's heart rate remains elevated after finishing a bout of intense exercise?

  1. The heart muscle has been permanently damaged
  2. The body is repaying the oxygen debt incurred during the effort Correct answer.
  3. Blood pressure has fallen below normal
  4. The parasympathetic nervous system is fully activated

Explanation

After intense exercise, oxygen consumption stays above resting levels to replenish phosphocreatine stores, remove metabolic by-products such as lactate, and restore oxygen to myoglobin, collectively known as excess post-exercise oxygen consumption or oxygen debt. This elevated metabolism keeps heart rate raised. The other options describe pathological or opposite physiological states.

Question 14Physical Education Studies

Which of the following best describes the concept of centre of gravity in relation to balance?

  1. The point at which the body's weight is evenly distributed in all directions Correct answer.
  2. The midpoint of the feet in contact with the ground
  3. The point where the most muscle mass is located
  4. The highest point of the body during a movement

Explanation

The centre of gravity is the point about which the body's mass is evenly distributed and through which the force of gravity acts. Balance is more stable when the line of gravity falls within the base of support, and lowering the centre of gravity increases stability. The other options confuse it with the base of support, body height or muscle distribution.

Question 15Physical Education Studies

A basketball player performs a lay-up and appears to hang in the air near the peak of the jump. Which concept best explains this illusion?

  1. The player's mass decreases at the top of the jump
  2. The player generates additional upward force while in the air
  3. The player's centre of gravity follows a parabolic path while the limbs move relative to it Correct answer.
  4. Gravity temporarily decreases at the peak of the jump

Explanation

Once airborne, the centre of gravity follows a fixed parabolic path determined by the take-off velocity and gravity, but the player can move the limbs and trunk around that centre. Raising the legs and arms near the peak makes the head appear to stay at the same height, creating the illusion of hanging. No extra force can be generated without contact with the ground, and gravity and mass do not change.

Question 16Physical Education Studies

Which of the following best explains the role of the stretch-shortening cycle in a countermovement jump?

  1. The concentric phase occurs before the eccentric phase
  2. The muscle contracts isometrically throughout the movement
  3. The jump relies entirely on the aerobic system for energy
  4. A rapid eccentric phase stores elastic energy that is released during the subsequent concentric phase Correct answer.

Explanation

In a countermovement jump the muscle-tendon units are rapidly stretched during the downward eccentric phase, storing elastic energy and triggering the stretch reflex. This stored energy and reflex contribution are then released during the immediate concentric push-off, increasing force and jump height. The sequence is eccentric then concentric, not isometric or reversed, and the effort is anaerobic.

Question 17Physical Education Studies

A coach periodises a season so that high-volume, low-intensity work occurs early and high-intensity, low-volume work occurs close to competition. Which principle does this best illustrate?

  1. The reversibility principle only
  2. The specificity principle only
  3. The general adaptation syndrome and the need for varied training stimuli across phases Correct answer.
  4. The principle of diminishing returns only

Explanation

Periodisation structures training into phases that manipulate volume and intensity to peak for competition, reflecting Selye's general adaptation syndrome in which the body passes through alarm, resistance and exhaustion stages. Varying the stimulus across phases prevents stagnation and overtraining. Reversibility, specificity and diminishing returns are related principles but do not by themselves explain the planned sequencing of volume and intensity.

Question 18Physical Education Studies

Two athletes perform the same vertical jump, but athlete A has a greater vertical displacement of the centre of gravity. Assuming both leave the ground with the same mass, which statement is correct?

  1. Both athletes generated identical impulse because the jump looks similar
  2. Athlete B generated a greater impulse during take-off
  3. Athlete A generated a greater impulse during take-off Correct answer.
  4. Impulse cannot be related to jump height

Explanation

Jump height depends on take-off velocity, which is determined by the net impulse applied during the push-off phase. A greater vertical displacement means a higher take-off velocity and therefore a larger net impulse for the same mass. The two athletes cannot have identical impulse if their jump heights differ, and impulse is directly related to the change in momentum that produces the jump.

Question 19Physical Education Studies

Which of the following best explains why lactate threshold is an important predictor of endurance performance?

  1. It marks the point at which the ATP-PC system becomes the dominant energy source
  2. It indicates the intensity at which lactate accumulates faster than it can be cleared, limiting sustained work Correct answer.
  3. It is the heart rate at which fat oxidation stops completely
  4. It represents the maximum force a muscle can produce

Explanation

The lactate threshold is the exercise intensity at which blood lactate begins to accumulate faster than it can be removed, signalling a shift toward greater anaerobic contribution and the onset of fatigue. A higher threshold allows an athlete to sustain a faster pace without early fatigue, making it a strong endurance predictor. It is not about the ATP-PC system, fat oxidation ceasing, or maximal force.

Question 20Physical Education Studies

Which of the following describes the agonist muscle during a bicep curl?

  1. The triceps brachii
  2. The deltoid
  3. The biceps brachii Correct answer.
  4. The pectoralis major

Explanation

In a bicep curl the elbow flexes, and the biceps brachii is the prime mover that contracts to produce this flexion. The triceps brachii is the antagonist that relaxes and lengthens to allow the movement. The deltoid moves the shoulder and the pectoralis major acts at the shoulder joint, so neither is the agonist for elbow flexion.

Question 21Physical Education Studies

Which of the following best describes the function of the cardiovascular system during exercise?

  1. To generate the nerve impulses that stimulate muscle contraction
  2. To deliver oxygen and nutrients to working muscles and remove carbon dioxide and wastes Correct answer.
  3. To store phosphocreatine for immediate energy use
  4. To produce ATP directly within the bloodstream

Explanation

The cardiovascular system transports oxygen and nutrients to active tissues and carries away carbon dioxide and metabolic by-products, supporting aerobic energy production. ATP is produced within muscle cells, nerve impulses come from the nervous system, and phosphocreatine is stored in muscle, not transported by blood.

Question 22Physical Education Studies

A hockey player must change direction quickly to evade a defender. Which fitness component is most directly being tested?

  1. Muscular endurance
  2. Agility Correct answer.
  3. Flexibility
  4. Aerobic power

Explanation

Agility is the ability to change direction rapidly and accurately while maintaining control, which is exactly what a quick evasive change of direction requires. Muscular endurance concerns repeated submaximal contractions, aerobic power concerns oxygen delivery during sustained work, and flexibility concerns range of motion. None of these directly describes rapid directional change.

Question 23Physical Education Studies

Which of the following is the correct definition of muscular strength?

  1. The ability to sustain a high heart rate for an extended time
  2. The ability to move a joint through its full range of motion
  3. The ability of a muscle to exert force against a resistance in a single maximal effort Correct answer.
  4. The ability of a muscle to repeatedly contract over a long period

Explanation

Muscular strength is the maximal force a muscle or muscle group can generate in a single effort against a resistance. Repeated contractions over time describe muscular endurance, range of motion describes flexibility, and sustained elevated heart rate relates to cardiorespiratory endurance. Each fitness component is defined by a distinct capacity.

Question 24Physical Education Studies

A coach records a player's results in a 20-metre sprint, a vertical jump and a multi-stage fitness test. What is the coach primarily doing?

  1. Designing a periodised training program
  2. Conducting a fitness testing battery to establish a baseline Correct answer.
  3. Diagnosing a medical condition
  4. Teaching a new skill

Explanation

A set of standardised tests measuring different fitness components provides baseline data on speed, power and aerobic capacity, allowing the coach to identify strengths and weaknesses and monitor progress. It is not a medical diagnosis, and while the data may inform programming, the act of testing itself is not program design or skill instruction.

Question 25Physical Education Studies

Which of the following best describes how the body dissipates heat during prolonged exercise in a hot environment?

  1. Through evaporation of sweat from the skin surface Correct answer.
  2. Through shivering of skeletal muscles
  3. Through increased storage of heat in the core
  4. Through constriction of skin blood vessels

Explanation

During exercise in the heat, sweat glands release fluid onto the skin and its evaporation removes heat from the body, which is the main cooling mechanism in warm conditions. Shivering generates heat rather than losing it, cutaneous vasoconstriction conserves heat, and storing heat in the core would raise core temperature dangerously rather than dissipate it.

Question 26Physical Education Studies

Which energy system is the primary contributor of ATP during a 100-metre sprint lasting about 10 seconds?

  1. The aerobic glycolysis system
  2. The lipolysis system
  3. The ATP-PC system Correct answer.
  4. The aerobic system

Explanation

Maximal efforts lasting roughly 10 seconds rely mainly on stored ATP and phosphocreatine, which can regenerate ATP very rapidly without oxygen. This ATP-PC (phosphagen) system fatigues quickly because phosphocreatine stores are limited, which is why sprint performance declines over repeated efforts.

Question 27Physical Education Studies

During a marathon, which fuel source provides the greatest proportion of energy for a well-trained runner?

  1. Anaerobic breakdown of glucose
  2. Intramuscular glycogen only
  3. Muscle phosphocreatine stores
  4. Fat oxidation in the mitochondria Correct answer.

Explanation

At the moderate, steady intensity of a marathon, the aerobic system dominates and fat becomes the major fuel because fat stores are large and yield high ATP per gram. Glycogen is still used but is progressively depleted, which is why carbohydrate intake and glycogen loading matter for performance.

Question 28Physical Education Studies

Which of the following best describes the term 'stroke volume'?

  1. The resistance the blood encounters in the vessels
  2. The volume of blood ejected by a ventricle per beat Correct answer.
  3. The volume of blood pumped by the heart per minute
  4. The number of heartbeats per minute

Explanation

Stroke volume is the amount of blood ejected from a ventricle with each contraction, commonly expressed in millilitres per beat. Cardiac output is the product of stroke volume and heart rate, so these concepts are related but distinct.

Question 29Physical Education Studies

A trained endurance athlete shows a lower resting heart rate than an untrained peer. Which adaptation best explains this?

  1. A reduced number of red blood cells
  2. A reduced maximal cardiac output
  3. A decreased blood plasma volume
  4. An increased resting stroke volume Correct answer.

Explanation

Endurance training enlarges the heart's chambers and strengthens the myocardium, so each beat ejects more blood. A larger stroke volume allows the same resting cardiac output to be achieved at a lower heart rate, producing bradycardia in trained athletes.

Question 30Physical Education Studies

Which of the following best describes the role of the respiratory system during incremental exercise?

  1. It stores oxygen for later use in the muscles
  2. It removes carbon dioxide and helps regulate acid-base balance Correct answer.
  3. It produces lactic acid to fuel the muscles
  4. It generates ATP independently of the muscles

Explanation

As exercise intensity rises, ventilation increases to deliver more oxygen and to clear the carbon dioxide produced by metabolism. Rapid removal of carbon dioxide also helps buffer the acidity that develops during high-intensity work.

Question 31Physical Education Studies

Which structure releases calcium ions to trigger muscle contraction?

  1. The myosin cross-bridge
  2. The sarcolemma
  3. The sarcoplasmic reticulum Correct answer.
  4. The mitochondria

Explanation

The sarcoplasmic reticulum stores calcium and releases it when an action potential travels into the muscle fibre. Calcium binds to troponin, shifting tropomyosin and allowing myosin heads to attach to actin and produce a contraction.

Question 32Physical Education Studies

A sprinter produces a very forceful contraction of the quadriceps during the push-off phase. Which type of muscle action is occurring at the quadriceps?

  1. Eccentric
  2. Concentric Correct answer.
  3. Isometric
  4. Passive

Explanation

A concentric action occurs when a muscle develops tension while shortening, which is what happens when the quadriceps extends the knee during push-off. This generates the force that drives the body forward.

Question 33Physical Education Studies

Which of the following best describes the concept of force summation in producing a powerful movement?

  1. Force is greatest when muscles shorten at maximum speed
  2. Successive contractions and coordinated joint actions combine to build force Correct answer.
  3. Muscles contract only when they are stretched
  4. Force production is independent of the number of motor units recruited

Explanation

Force summation refers to combining the effects of successive stimuli and coordinating body segments so that forces accumulate in the desired direction. Skilled performers sequence proximal and distal segments so that forces peak together, producing maximal output.

Question 34Physical Education Studies

A gymnast wants to increase rotational speed during a tuck somersault. Which action best achieves this?

  1. Extending the arms and legs to increase the moment of inertia
  2. Pulling the knees tightly to the chest to reduce the moment of inertia Correct answer.
  3. Keeping the body fully extended throughout the rotation
  4. Increasing the radius of rotation about the transverse axis

Explanation

Angular momentum is conserved when no external torque acts, so reducing the moment of inertia by tucking increases angular velocity. Pulling the knees to the chest brings mass closer to the axis of rotation, allowing faster spinning.

Question 35Physical Education Studies

Which of the following best describes the relationship between impulse and change in momentum?

  1. Impulse equals power divided by time
  2. Impulse equals mass multiplied by velocity squared
  3. Impulse equals the product of force and the time over which it acts Correct answer.
  4. Impulse equals the force applied at a single instant only

Explanation

Impulse is the product of the average force and the time it acts, and it equals the change in momentum of the body. This is why extending the time of force application, such as following through in a throw, increases the resulting velocity.

Question 36Physical Education Studies

Which of the following best describes the term 'leverage' as applied to a human movement such as a calf raise?

  1. The total mass of the body determines the speed of movement
  2. The ratio of load to effort arm length determines mechanical advantage Correct answer.
  3. The number of joints involved determines the type of contraction
  4. The length of the muscle determines the direction of gravity

Explanation

Mechanical advantage is the ratio of the effort arm to the resistance arm, so a longer effort arm allows a given force to move a larger load. In the calf raise the foot forms a lever with the ankle as the axis, and the arrangement affects how much force the calf must produce.

Question 37Physical Education Studies

Which of the following best describes the principle of progressive overload?

  1. Training should only involve the same exercises each week
  2. Training stress must gradually increase to produce continued adaptation Correct answer.
  3. Training loads should remain constant to allow full recovery
  4. Training intensity should be reduced as fitness improves

Explanation

Progressive overload means systematically increasing training stress as the body adapts, so that the stimulus stays above the current capacity. Without this progression, adaptation plateaus because the body is no longer challenged.

Question 38Physical Education Studies

A coach schedules a recovery week with reduced training volume after three heavy weeks. Which training principle does this best illustrate?

  1. Specificity
  2. Individuality
  3. Variation and recovery Correct answer.
  4. Reversibility

Explanation

Deliberately reducing load after a block of hard training is an application of variation and recovery, allowing supercompensation to occur. Planned recovery prevents overtraining and allows the adaptations from the loading phase to be realised.

Question 39Physical Education Studies

Which of the following best describes the purpose of a warm-up before vigorous activity?

  1. To lower heart rate and reduce neural drive
  2. To deplete glycogen stores before exercise
  3. To raise muscle temperature and increase blood flow to working muscles Correct answer.
  4. To increase muscle viscosity and reduce blood flow

Explanation

A warm-up raises muscle temperature, increases blood flow and enhances nerve conduction, which together improve power output and reduce injury risk. It also allows rehearsal of movement patterns before the main activity.

Question 40Physical Education Studies

Which of the following best describes the purpose of a cool-down after intense exercise?

  1. To immediately increase heart rate to maximal levels
  2. To build muscle strength through overload
  3. To increase muscle temperature rapidly
  4. To promote gradual return of blood flow and reduce venous pooling Correct answer.

Explanation

A cool-down keeps blood moving through active muscles as heart rate falls, which helps prevent dizziness from venous pooling and assists removal of metabolic by-products. It also aids the gradual return to resting physiological states.

Question 41Physical Education Studies

Which of the following is the most appropriate way to reduce the risk of heat illness during a pre-season session in hot weather?

  1. Scheduling sessions during the hottest part of the day
  2. Requiring athletes to wear extra clothing to increase sweat loss
  3. Restricting fluid intake to prevent stomach discomfort
  4. Providing regular fluid breaks and monitoring athletes for early warning signs Correct answer.

Explanation

Fluid replacement and vigilant monitoring of early symptoms such as dizziness, cramps and confusion are central to preventing heat illness. Scheduling activity away from peak heat and allowing acclimatisation further reduce risk.

Question 42Physical Education Studies

Which of the following best describes the RICER protocol for an acute soft-tissue injury?

  1. Rest, ice, compression, elevation, referral Correct answer.
  2. Resistance, intensity, conditioning, endurance, recovery
  3. Run, ice, compress, elevate, return to play
  4. Rest, immobilise, cool, exercise, return

Explanation

RICER stands for rest, ice, compression, elevation and referral, which together limit bleeding and swelling in the first 48 hours after injury. Referral ensures appropriate professional assessment for more serious damage.

Question 43Physical Education Studies

A coach wants to develop a footballer's ability to repeatedly sprint and recover over a match. Which training method is most appropriate?

  1. Low-resistance circuit training with long rests
  2. Long slow distance running at low intensity
  3. Static stretching sessions
  4. High-intensity interval training with work-to-rest ratios Correct answer.

Explanation

Repeated-sprint ability depends on both anaerobic power and aerobic recovery, which high-intensity interval training develops through alternating hard efforts and recovery periods. The work-to-rest ratio can be manipulated to match the demands of the sport.

Question 44Physical Education Studies

Which of the following best explains why a coach should use a battery of fitness tests rather than a single test?

  1. Batteries remove the need for validity
  2. A single test cannot be scored objectively
  3. Different tests measure different components of fitness relevant to performance Correct answer.
  4. One test is always unreliable

Explanation

Sport performance depends on several fitness components, so a battery covering speed, power, endurance and agility gives a fuller profile. This allows the coach to target weaknesses and monitor changes across multiple qualities.

Question 45Physical Education Studies

A 20-metre sprint test is repeated twice with only 30 seconds of rest, and the second result is much slower. Which fitness component is being assessed by the decline in performance?

  1. Repeated-sprint ability Correct answer.
  2. Maximum strength
  3. Aerobic power
  4. Static flexibility

Explanation

A marked drop in sprint performance after short recovery indicates limited ability to recover between maximal efforts, which reflects repeated-sprint ability. This quality depends on phosphocreatine resynthesis and aerobic recovery between efforts.

Question 46Physical Education Studies

Which of the following best describes the function of a motor unit?

  1. A sensory receptor in a tendon
  2. A motor neuron and all the muscle fibres it innervates Correct answer.
  3. A group of joints acting together
  4. A single muscle fibre and its blood supply

Explanation

A motor unit consists of one motor neuron and the muscle fibres it activates, which contract together when stimulated. Recruiting more motor units increases the force produced by the muscle.

Question 47Physical Education Studies

A beginner learning a new skill shows large, inconsistent errors early in practice. Which stage of skill acquisition best describes this?

  1. The cognitive stage Correct answer.
  2. The autonomous stage
  3. The associative stage
  4. The retention stage

Explanation

In the cognitive stage the learner must consciously think about the movement, producing large and variable errors and relying heavily on feedback. As practice continues, the learner moves into the associative and then autonomous stages with more consistent performance.

Question 48Physical Education Studies

Which of the following best describes the difference between massed and distributed practice?

  1. Massed practice is only used for closed skills
  2. Massed practice uses longer sessions with shorter rest intervals between trials Correct answer.
  3. Distributed practice involves no rest at all between trials
  4. Distributed practice always produces faster learning than massed practice

Explanation

Massed practice involves continuous practice with little rest, while distributed practice spreads trials across sessions with longer recovery periods. Distributed practice often benefits learning and retention, particularly for beginners or complex skills.

Question 49Physical Education Studies

A coach provides feedback during a training drill about the angle of the elbow in a throw. Which type of feedback is this?

  1. Extrinsic reinforcement of effort
  2. Knowledge of results
  3. Intrinsic sensory feedback
  4. Knowledge of performance Correct answer.

Explanation

Knowledge of performance gives information about the quality or technique of the movement itself, such as limb position. Knowledge of results, in contrast, describes the outcome of the movement, such as where the ball landed.

Question 50Physical Education Studies

Which of the following best explains how observational learning can assist skill acquisition?

  1. It removes the need for feedback from a coach
  2. It guarantees immediate autonomous performance
  3. It replaces the need for any physical practice
  4. It allows learners to form a mental model of the movement before practising Correct answer.

Explanation

Observing a skilled model helps learners build a cognitive representation of the movement, which they can then attempt and refine through practice. Observation complements rather than replaces physical practice and feedback.
