A student wants to investigate the relationship between heart rate and blood pressure responses during a 20-minute aerobic training session. Analyse suitable methods for collecting this data and explain potential challenges they might face.   (8 marks)

Show Answers Only

Sample Answer 

Overview Statement

  • Investigating heart rate and blood pressure during aerobic training involves comparing continuous versus interval measurement methods.
  • These methods differ in accuracy and practical challenges during exercise sessions.

Method 1: Heart Rate Monitoring

  • Heart rate monitors provide continuous data collection throughout the entire 20-minute aerobic session without interruption.
  • Continuous monitoring enables uninterrupted cardiovascular tracking that connects to real-time exercise responses without stopping physical activity.
  • The relationship between continuous monitoring and exercise intensity means accurate heart rate patterns and recovery phases can be recorded.
  • Data collection results in comprehensive cardiovascular information but creates challenges with equipment positioning, battery life, and signal interference during vigorous movement.
  • However, this leads to potential skin irritation issues and requires proper chest strap fitting for accurate readings.

Method 2: Blood Pressure Measurement

  • Digital blood pressure cuffs require exercise interruption at regular intervals to obtain accurate systolic and diastolic readings.
  • Measurement gaps create interruptions that affect continuous data collection and may alter natural exercise responses during the session.
  • The interaction between exercise stoppage and blood pressure readings leads to potential recovery effects and cooling between measurements.
  • Equipment setup generates practical challenges including timing coordination, participant positioning difficulties, and cuff size variations.
  • Therefore timing becomes critical to balance data collection needs with maintaining exercise intensity levels.

Implications and Challenges

  • The significance is that combining both methods reveals important cardiovascular relationships but creates coordination, timing, and accuracy challenges.
  • Students must balance comprehensive data quality with practical measurement limitations using accessible school equipment and proper technique.

A student wants to investigate how environmental conditions affect body temperature during a 30-minute aerobic training session. Analyse TWO different environmental conditions they could use to collect this data.   (6 marks)

Show Answers Only

Sample Answer 

Overview Statement

  • Investigating environmental effects on body temperature during aerobic training involves comparing indoor versus outdoor exercise conditions.
  • These conditions differ in heat exposure and how hard the body works to control temperature.

Condition 1: Indoor Training Environment

  • Students perform aerobic exercises in a controlled indoor space with steady temperature and no extra heat sources.
  • This enables stable conditions that reduce outside temperature factors affecting body temperature changes.
  • The relationship between controlled conditions and measurement accuracy means more reliable temperature data collection.
  • This approach results in easier digital thermometer readings without weather problems or extra heat stress.

Condition 2: Outdoor Training Environment

  • Students perform identical aerobic exercises outdoors on a warm day with direct sun exposure.
  • This creates extra environmental heat stress that influences how the body controls temperature during exercise.
  • The interaction between outside heat and internal exercise heat leads to higher body temperature readings.
  • However, this generates extra factors like wind and humidity that affect how the body cools itself.

Implications

  • The significance is that comparing both environments reveals how outside conditions impact body temperature responses.
  • Therefore this method enables students to understand environmental effects using simple digital thermometer equipment.

Explain the advantages and limitations of using a Rating of Perceived Exertion (RPE) scale when collecting data on aerobic training responses.   (5 marks)

Show Answers Only

Sample Answer 

  • The RPE scale provides subjective data on exercise intensity without requiring specialised equipment, making it accessible for all research settings. This accessibility is beneficial because it reduces costs and enables widespread use.
  • Participants can provide RPE ratings without interrupting their exercise, allowing continuous data collection throughout an aerobic session. This enables researchers to track intensity changes.
  • The scale’s portability enables data collection in natural training environments where laboratory equipment is impractical. This creates more realistic training conditions.
  • However, the subjective nature of RPE introduces potential reliability issues as perception varies between individuals based on fitness levels, pain tolerance and motivation. This variability can affect consistency of results.
  • Prior training of participants in using the RPE scale correctly is essential to ensure consistency in how ratings are assigned. This training requirement adds time and complexity.
  • RPE provides valuable complementary data when used alongside objective physiological measures, creating a complete picture.

Explain what happens to blood lactate levels during aerobic training of increasing intensity.   (5 marks)

Show Answers Only

Sample Answer 

  • At rest, blood lactate levels remain low at approximately 1-2 mmol/L. This occurs because the aerobic system meets all energy demands without producing excess lactate.
  • During light to moderate aerobic exercise, lactate production increases slightly as a result of increased energy demands. However, it remains in equilibrium with clearance due to sufficient oxygen availability.
  • When exercise intensity increases to the aerobic threshold, lactate levels begin to rise gradually. The reason for this is that energy demands are approaching the capacity of the aerobic system, though the body can still manage lactate clearance effectively.
  • At the lactate threshold/inflection point, lactate production exceeds the body’s ability to clear it. This happens because insufficient oxygen delivery forces a shift toward anaerobic metabolism.
  • Beyond this point, lactate accumulates rapidly in the bloodstream. Consequently, increased muscle acidity develops, which leads to fatigue and limits performance duration.

  • Ventilation rate increases immediately when aerobic exercise begins. This occurs because working muscles demand more oxygen for energy production.
  • Breathing depth increases to maximise lung capacity. As a result, more oxygen enters the lungs with each breath, improving oxygen availability.
  • Breathing frequency rises from rest to meet metabolic demands. This happens because the body needs to maintain adequate oxygen supply and carbon dioxide removal.
  • Therefore, increased ventilation prevents acid-base imbalance in the blood. Higher breathing rates enable efficient removal of carbon dioxide produced during metabolism.
  • Respiratory muscles work harder to support these changes. Consequently, the diaphragm and intercostal muscles contract more forcefully to facilitate air movement.

  2. Explain TWO immediate physiological responses that occur alongside changes in lactate levels during high-intensity swimming.   (3 marks)
  3. Outline ONE benefit of monitoring lactate levels during swimming training.   (2 marks)
Show Answers Only

Sample Answer 

a.   Relationship between exercise intensity and lactate production

  • At low swimming intensities (easy warm-up pace), lactate levels remain close to resting values (1-2 mmol/L) as the aerobic system adequately meets energy demands.
  • As swimming intensity increases to moderate levels, there is a gradual increase in lactate production, though the body can still effectively clear most lactate produced.
  • During high-intensity swimming (race pace), lactate levels rise significantly (may exceed 8-10 mmol/L) as the glycolytic energy system becomes the primary energy provider, producing lactate as a by-product.

b.   Immediate physiological responses –  Any TWO of the following

  • Heart rate increases substantially during high-intensity swimming as the cardiovascular system works to deliver more oxygen to working muscles, rising in proportion to the increase in lactate levels.
  • Ventilation rate (breathing rate) increases dramatically alongside rising lactate levels, as the swimmer attempts to take in more oxygen and expel carbon dioxide, often resulting in the characteristic gasping for air seen at the end of a race.
  • Stroke volume may initially increase but then plateau during very high-intensity swimming when lactate levels are highest.
  • Cardiac output increases proportionally with intensity to support greater oxygen demand and assist with lactate clearance.

c.   Benefit – Any ONE of the following

  • Monitoring lactate levels allows the coach to precisely determine appropriate training intensities for specific energy system development, ensuring the swimmer trains at the correct intensity to improve performance in the 200 m event.
  • Lactate testing provides objective feedback about the swimmer’s physiological response to training, allowing for adjustments to training volume and intensity based on individual adaptations rather than subjective feelings of effort.
  • Regular lactate monitoring can track improvements in the swimmer’s fitness, with lower lactate levels at the same swimming speed indicating enhanced aerobic capacity and efficiency.

  • Sprinters experience rapid lactate accumulation within seconds of starting. Marathon runners sustain steady lactate levels throughout their race.
  • Sprinters rely entirely on lactate tolerance for brief periods. Marathon runners train to maximise lactate clearance and aerobic efficiency.
  • Sprint events cause severe muscle burning from extreme lactate accumulation. Marathon runners experience minimal lactate-related discomfort until late stages.
  • Recovery differs significantly between events. Sprinters need extended time to clear high lactate levels post-race.

Examples:

Explain the significance of lactate levels for a 1500-metre runner during training. Provide an example to support your answer.   (5 marks)

Show Answers Only

Sample Answer 

  • Lactate levels indicate exercise intensity and energy system usage for 1500-metre runners. This is significant because the event requires both aerobic and anaerobic contributions.
  • At the lactate threshold, blood lactate concentration increases sharply. The increase occurs when the shift from aerobic to anaerobic metabolism begins.
  • Training at or above this threshold improves lactate clearance ability. As a result, runners can maintain higher speeds before fatigue sets in.
  • Therefore, monitoring lactate helps coaches prescribe appropriate training intensities. Precise monitoring enables targeted development of specific energy systems for optimal performance.
  • Regular lactate testing allows precise adjustment of training zones. Consequently, runners avoid under-training or over-training at crucial intensities.
  • For example, a runner might perform 6 × 400m intervals at threshold pace. These intervals cause moderate lactate accumulation, which leads to improved lactate tolerance and clearance ability.

Sample Answer 

  • At rest and during low-intensity exercise, lactate levels remain minimal. The aerobic system effectively meets energy demands without significant lactate accumulation.
  • As intensity increases to moderate levels, lactate production rises gradually. The body maintains balance between lactate production and removal.
  • At the lactate threshold during high-intensity exercise, production suddenly exceeds clearance ability. Blood lactate concentration increases sharply from this point.
  • During very high-intensity or maximal exercise, lactate accumulates rapidly in muscles and blood. This increasing acidity contributes to fatigue and limits performance duration.

Show Answers Only

Sample Answer

Evaluation Statement:

  • The interaction between cardiac output, ventilation rate and lactate levels proves highly effective in meeting high-intensity exercise demands.
  • These systems work together to maintain performance despite metabolic stress.

Criterion 1 – System Coordination Effectiveness:

  • Evidence indicates that cardiac output increases coordinate strongly with ventilation rate rises. Both systems respond immediately to exercise demands.
  • Synchronisation effectively delivers oxygen and removes carbon dioxide. The cardiovascular and respiratory systems work in harmony.
  • Rising lactate levels trigger respiratory compensation, demonstrating excellent integrated responses. Increased ventilation helps buffer accumulating acid.
  • The systems achieve significant mutual support during intense exercise. Each component enhances the effectiveness of the others.
  • Cardiac output provides the transport while ventilation supplies the oxygen. Lactate levels signal the need for increased respiratory effort.

Criterion 2 – Performance Maintenance:

  • The interactions partially fulfill performance needs as exercise continues. Initial responses meet demands effectively.
  • Cardiac output sustains oxygen delivery throughout high-intensity work. Elevated ventilation attempts to buffer increasing acidity from lactate accumulation.
  • However, limitations appear when lactate exceeds clearance capacity. The buffering system becomes overwhelmed at extreme intensities.
  • Performance maintenance proves moderately successful in delaying fatigue. Complete prevention remains impossible at sustained high intensities.
  • Recovery between intervals allows partial system restoration. Brief rest periods enable continued high-intensity efforts.

Final Evaluation:

  • The three systems demonstrate highly effective initial coordination. Integration allows remarkable performance capacity.
  • Limitations emerge as intensity continues and lactate overwhelms buffering capacity. Physiological constraints eventually dominate.
  • Despite these constraints, the integrated response proves largely successful. Human performance reaches impressive levels through system cooperation.
  • The systems work optimally within physiological limits to support high-intensity performance. Overall effectiveness remains substantial.

Show Answers Only

Sample Answer

Evaluation Statement:

  • Training types affect stroke volume differently.
  • Aerobic training proves highly effective for endurance sports.
  • Resistance training shows limited cardiovascular benefits for power sports.

Criterion 1 – Stroke Volume Response Effectiveness:

  • Aerobic training strongly meets the needs of endurance athletes. Substantial stroke volume increases can be sustained throughout exercise.
  • Consistent oxygen supply proves crucial for marathon running or cycling. Endurance athletes rely heavily on this cardiovascular response.
  • In contrast, resistance training partially fulfills power athletes’ needs. Brief stroke volume spikes occur during lifts.
  • However, minimal sustained cardiovascular benefits result from resistance training. Power athletes experience limited stroke volume improvements.
  • Such limitations matter less for weightlifters. Different energy systems drive their performance requirements.

Criterion 2 – Performance Transfer:

  • Evidence indicates that aerobic training’s stroke volume improvements directly enhance endurance performance. Improved oxygen delivery efficiency results from these changes.
  • Athletes maintain higher cardiac output with lower heart rates. Energy conservation over long durations becomes possible.
  • Power training shows strong muscular development but limited stroke volume contributions. ATP-PCr and glycolytic systems drive performance more than oxygen transport.
  • The mismatch between training response and sport demands is acceptable. Power sports require explosive force rather than sustained oxygen delivery.

Final Evaluation:

  • Weighing these factors shows aerobic training produces highly effective stroke volume responses. Endurance performance benefits significantly from these cardiovascular improvements. 
  • Resistance training’s limited stroke volume benefits remain adequate for power sports. Other energy systems matter more than cardiovascular changes in power activities.
  • Therefore, matching training type to sport demands proves optimal. Each training method serves its intended purpose effectively.

Explain the relationship between stroke volume, heart rate and cardiac output during an aerobic training session.   (6 marks)

Show Answers Only

Sample Answer

  • Cardiac output functions through the interaction of stroke volume and heart rate. The formula CO = SV × HR demonstrates this direct relationship.
  • At exercise onset, both components increase immediately. The plateau happens because working muscles demand more oxygen for energy production.
  • Stroke volume rises from resting values to near-maximum levels quickly. As a result, cardiac output increases substantially within the first minutes of exercise.
  • However, stroke volume plateaus at moderate intensity while heart rate continues rising. This happens because ventricular filling time decreases at higher heart rates.
  • Therefore, further cardiac output increases depend primarily on heart rate. The shift occurs when stroke volume reaches its maximum capacity at moderate intensities.
  • During sustained aerobic exercise, heart rate becomes the main contributor. Consequently, cardiac output can continue increasing despite stable stroke volume.
  • The recovery phase shows different response patterns. Heart rate drops rapidly while stroke volume decreases more gradually.
  • These differences occur because neural control affects heart rate immediately. Stroke volume changes depend on venous return and contractility adjustments.
  • Overall, the relationship between components enables flexible cardiac output regulation. Such coordination allows the cardiovascular system to meet varying oxygen demands throughout aerobic training.

Show Answers Only

Sample Answer

Overview Statement:

  • Training status influences ventilation efficiency during submaximal exercise through physiological improvements and movement coordination. These components interact to reduce respiratory demands in trained individuals.

Component Relationship 1:

  • Training status directly affects ventilation rate at given workloads. Trained individuals demonstrate lower breathing rates than untrained people at the same intensity.
  • The reduction occurs because improved oxygen extraction efficiency reduces ventilatory demands. Enhanced mitochondrial density enables muscles to use oxygen more effectively.
  • As a result, trained athletes require less ventilation to meet oxygen needs. These changes reveal how training creates respiratory efficiency advantages.

Component Relationship 2:

  • Movement-breathing coordination connects to training experience levels. Experienced athletes develop synchronised breathing patterns that match their activity rhythm.
  • Runners link breathing to stride patterns while swimmers coordinate with stroke cycles. This relationship demonstrates efficient respiratory-movement integration.
  • Therefore, coordinated breathing reduces unnecessary respiratory effort. This pattern shows how practice improves ventilation economy.

Implications and Synthesis:

  • These components work together to create superior ventilation efficiency in trained individuals. The interaction between physiological improvements and coordination determines overall respiratory response.
  • Consequently, training status enables athletes to sustain submaximal exercise with less respiratory stress. Improved efficiency means improved performance capacity through reduced ventilation demands.

Explain the relationship between ventilation rate and lactate levels during and after high-intensity exercise.   (5 marks)

Show Answers Only

Sample Answer

  • During high-intensity exercise, ventilation rate increases significantly. This occurs because working muscles require more oxygen and produce excess carbon dioxide.
  • As intensity exceeds the aerobic threshold, lactate accumulates in the bloodstream. This happens due to insufficient oxygen for complete aerobic metabolism.
  • The rising lactate levels cause blood pH to decrease, creating an acidic environment. As a result, hydrogen ions accumulate alongside lactate in the blood.
  • This triggers the respiratory control centre to increase ventilation rate further. Therefore, rapid breathing helps buffer the acidity by expelling more carbon dioxide.
  • The relationship creates a compensatory mechanism where higher lactate leads to increased ventilation. This process helps maintain blood pH within tolerable limits during intense exercise.
  • After exercise ceases, ventilation remains elevated because lactate clearance continues. Consequently, breathing rate gradually returns to normal as lactate levels decrease during recovery.

Explain how immediate cardiac responses differ between resistance training and endurance training.   (6 marks)

Show Answers Only

Sample Answer 

Heart rate response:

  • Endurance training increases heart rate to a steady elevated level. This occurs because continuous oxygen demand requires sustained cardiac work.
  • Resistance training causes heart rate spikes during sets. This happens due to intense muscular effort followed by recovery periods between set.

Stroke volume changes:

  • Endurance training produces sustained stroke volume increases throughout the session. As a result, consistent oxygen delivery supports continuous muscle activity.
  • Resistance training creates temporary stroke volume increases during lifting. This is because muscle contractions affect venous return intermittently.

Blood pressure:

  • Resistance training causes greater blood pressure increases than endurance training. This occurs when muscles contract forcefully and compress blood vessels during lifting phases.

Cardiac output patterns:

  • Resistance training produces varying cardiac output with peaks and valleys. Therefore, oxygen delivery fluctuates between work and rest intervals.
  • Endurance training maintains elevated cardiac output consistently. This enables steady oxygen supply for sustained aerobic metabolism.

Venous return:

  • Resistance training may temporarily restrict blood flow. This happens because intense muscle contractions compress veins during lifting.
  • Endurance training promotes continuous venous return. Consequently, rhythmic muscle contractions assist blood flow back to the heart.

Recovery between efforts:

  • Resistance training allows partial cardiac recovery between sets. This results in decreased heart rate and blood pressure during rest intervals.
  • Endurance training requires continuous cardiac work. Therefore, minimal recovery occurs during the activity.

Evaluate how the four components of the FITT principle interact when designing a training program for a 100 m sprinter. In your response, address how each component affects the body's energy systems and fitness improvements.   (12 marks)

Show Answers Only

Sample Answer

Evaluation Statement:

  • The FITT components demonstrate highly effective interaction for sprint training when properly integrated.
  • Key criteria include energy system targeting, movement skill development, and component relationships.

Energy System Targeting:

  • Intensity at 90-100% maximum strongly meets ATP-PCr system requirements, using immediate energy stores within 10 seconds.
  • Time components of 5-10 second efforts prove optimal for developing explosive power.
  • While frequency allows energy system recovery, excessive sessions fail to achieve fitness improvements.
  • The evidence indicates that proper intensity-time combination drives improved energy storage capacity.

Movement Skill Development:

  • High-intensity efforts effectively develop explosive muscle fibres essential for sprinting speed.
  • Short time intervals maintain movement quality throughout efforts, preventing fatigue-induced technique breakdown.
  • Frequency at 3-4 sessions adequately fulfils skill learning needs while avoiding excessive muscle fatigue.
  • Sprint-specific training types prove superior for developing speed and power coordination.

Component Relationships:

  • Evidence supporting integration includes inverse relationships between variables – increasing intensity necessitates reduced frequency or duration.
  • Work-to-rest ratios of 1:10-20 demonstrate time-recovery connections for maintaining training quality.
  • Although effective for power development, excessive intensity without adequate recovery proves insufficient for consistent improvement.
  • Type selection influences all other components through specific fatigue patterns.

Final Evaluation:

  • Weighing these factors shows optimal interaction occurs through careful manipulation.
  • The strengths outweigh the weaknesses because integrated programming maximises explosive development while preventing overtraining.
  • Most effective programs adjust components inversely – as competition approaches, intensity increases while volume decreases.
  • While strong in isolation, components prove less suitable for performance without systematic integration.
  • Sprint performance ultimately depends on balancing maximum effort training with complete recovery.

  • Court-based sprint drills develop basketball-specific anaerobic power through suicide runs, baseline-to-baseline sprints, and defensive slide patterns.
  • These movements are effective because they replicate game demands of 5-15 second high-intensity bursts.
  • This ensures direct transfer to match performance during fast breaks and defensive plays.
  • Plyometric exercises build explosive power essential for rebounding and shot-blocking.
  • Box jumps (40-60cm), depth jumps, and lateral bounds develop vertical and horizontal power.
  • Medicine ball chest passes and overhead throws enhance upper body explosiveness which improves passing and shooting power.
  • Resistance training using moderate loads for 3-8 repetitions develops strength for basketball movements.
  • Squats and deadlifts build lower body power for jumping, while bench press and rows develop contact strength for post play.
  • This type of training is necessary because basketball requires both explosive movements and physical contact.
  • Circuit training combines basketball skills with anaerobic conditioning to create sport-specific fitness.
  • Stations alternate between dribbling sprints, defensive slides, jump shots, and agility ladder work.
  • 30 seconds maximum effort with 60-90 seconds recovery replicates game work-to-rest patterns.
  • This training method is effective because it maintains skill development while building anaerobic fitness for basketball’s repeated high-intensity demands.

Show Answers Only

Sample Answer

Similarities:

  • Both training methods require specific time durations to target their respective energy systems effectively.
  • Both need sufficient time to create training stimulus and promote fitness improvements.
  • Both require planned recovery periods, though at different intervals.

Differences:

  • Glycolytic training uses short work intervals of 30-90 seconds targeting the lactic acid system.
  • Aerobic training involves continuous activity lasting 20-60+ minutes at moderate intensity.
  • Glycolytic sessions total 15-30 minutes of high-intensity work due to accumulated fatigue.
  • Aerobic sessions extend much longer without excessive fatigue because of steady-state exercise.
  • Glycolytic training requires work-to-rest ratios of 1:2-3 to allow partial lactate clearance.
  • Aerobic training needs no rest intervals as steady-state exercise allows ongoing oxygen delivery.

Physiological responses from time differences:

  • Shorter glycolytic intervals create metabolic stress, which improves lactate buffering capacity.
  • This leads to enhanced glycolytic enzyme activity and better lactate removal.
  • Longer aerobic duration stimulates cardiovascular responses resulting in improved oxygen delivery.
  • Extended moderate intensity causes enhanced fat utilisation efficiency.
  • These distinct responses reflect each energy system’s role in different performance demands.

Show Answers Only

Sample Answer – Chosen sport – Netball

  • Pre-season allows higher training frequency because no competitive matches exist to create additional stress.
  • Athletes can train 5-6 times weekly as recovery time is dedicated solely to training demands.
  • Example: A netball player completes 5 training sessions weekly during pre-season preparation.
  • In-season frequency must be reduced due to the physical and mental demands of regular competition.
  • This reduction is necessary because match play provides high-intensity stimulus requiring recovery time.
  • Training frequency drops to 2-3 sessions weekly to prevent accumulated fatigue affecting performance.
  • Match demands create significant physiological stress which limits available recovery time for additional training.
  • Therefore in-season training focuses on maintaining fitness rather than building new improvements.
  • Example: The same netball player reduces to 2 light training sessions between weekend matches.
  • This modification ensures optimal performance on match day while preventing overtraining and injury risk.

Show Answers Only

Sample Answer

Overview Statement:

  • Swimming and running require different FITT applications due to their distinct environmental and biomechanical demands.
  • Key relationships exist between impact stress and frequency, body position and intensity measurement, plus equipment constraints affecting type variety.

Component Relationship 1:

  • Impact stress levels directly influence frequency capabilities between these activities.
  • Swimming enables 5-6 weekly sessions because water buoyancy reduces joint stress, while running limits training to 3-4 sessions due to high impact forces.
  • Water supports body weight, preventing overuse injuries that commonly affect runners.
  • This relationship means swimmers can accumulate greater weekly training volume without injury risk.

Component Relationship 2:

  • Environmental factors connect to intensity measurement accuracy and session duration.
  • Horizontal body position in water causes heart rates to run 10-15 beats lower than land-based activities.
  • This forces swimmers to rely on perceived exertion or pace times rather than heart rate monitoring.
  • Additionally, water resistance increases energy expenditure, resulting in shorter session durations (45-60 minutes) compared to running (60-90 minutes) for equivalent training stimulus.

Implications and Synthesis:

  • These component relationships demonstrate how environmental constraints shape FITT application.
  • Swimming’s supportive environment allows higher frequency but restricts type variety to stroke variations.
  • Running’s impact stress limits frequency but provides diverse terrain options.
  • The significance is that effective aerobic programs must adapt FITT components to match each activity’s unique biomechanical and environmental demands.

  • Both require 48-72 hour recovery periods between high-intensity anaerobic sessions.

Differences:

  • Tennis players can manage 2-3 weekly sessions due to high impact stress from jumping and lunging.
  • 100m swimmers can handle 3 sessions as water-based training reduces joint stress, allowing quicker recovery.
  • Tennis training emphasises multi-directional movements through court sprints, lunging patterns and plyometric jumps.
  • 100m swimming focuses on linear sprint power through 25-50m sprint sets and explosive starts.
  • Tennis sessions include agility ladders and reaction drills for sudden direction changes and net play.
  • 100m swimmers use resistance equipment like parachutes and paddles for stroke-specific power development.
  • Tennis “type” component addresses explosive racquet swing power and rapid court coverage.
  • 100m swimming “type” component develops propulsive force and streamlined body position for maximum speed.

A sports scientist is designing an anaerobic training program for an Olympic weightlifter based on the FITT principle. Which of the following combinations would be most appropriate?

  1. Frequency: daily training; Intensity: RPE 5-6; Time: 45-minute continuous sessions; Type: high-repetition Olympic lifts
  2. Frequency: 4-5 sessions per week; Intensity: RPE 8-9; Time: sets of 1-5 repetitions with 3-5 minute rest periods; Type: Olympic lifts and strength exercises
  3. Frequency: 2 sessions per week; Intensity: RPE 7; Time: 30-second maximum effort circuits; Type: machine-based resistance training
  4. Frequency: 6 sessions per week; Intensity: RPE 6-7; Time: 20-repetition sets with 1-minute rest periods; Type: bodyweight exercises

Show Worked Solution
  • B is correct: Optimal frequency, high intensity, low reps with long rest for power development.

Other Options:

  • A is incorrect: Daily training excessive; low intensity/high reps for endurance not power.
  • C is incorrect: Insufficient frequency; machines lack Olympic lift technique requirements.
  • D is incorrect: Low intensity/high reps develop endurance not explosive power.

Any 2 of the following

NOTE: Students should describe any TWO of the training types in detail, ensuring they explain how each type is implemented and its relevance to rugby performance.

Sprint interval training

  • Develops the ATP-PCr system through 10-30 metre maximal sprints with full recovery between efforts.
  • This training replicates explosive bursts needed for line breaks and support play in rugby matches.

Plyometric exercises

  • Develops the ATP-PCr system through 10-30 metre maximal sprints with full recovery between efforts.
  • This training replicates explosive bursts needed for line breaks and support play in rugby matches.

Circuit training

  • Combines 6-8 rugby-specific anaerobic stations such as tackle bags, agility ladders and medicine ball throws.
  • Athletes work at high intensity for 20-30 seconds per station with recovery periods.

Resistance training

  • Uses heavy loads at 80-90% 1RM for 1-5 repetitions with extended rest periods.
  • Compound movements like squats, deadlifts and power cleans build maximal strength for scrummaging and ruck contests.

Explain how you would modify the 'Frequency' component of the FITT principle for a netball player during pre-season versus in-season anaerobic training.   (4 marks)

Show Answers Only

Sample Answer

  • Pre-season allows 3-4 anaerobic sessions weekly because building fitness base is priority without match demands competing for recovery time.
  • This enables 24-48 hour recovery between sessions, which allows fitness development while preventing overtraining in netball players.
  • In-season requires reducing to 1-2 dedicated anaerobic sessions weekly because match play provides game-intensity stimulus that replaces some training needs.
  • Consequently, 48-72 hour recovery becomes necessary due to accumulated fatigue from competitive matches combined with training loads.
  • This modification occurs because pre-season has no competitive stress, whereas in-season requires balancing training with match demands to maintain performance without causing burnout.
  • Therefore, frequency adjustments ensure optimal performance by matching training load to the player’s total stress and recovery capacity.
