HSC Health and Movement Science Focus Area 2: the 2026 guide

What this guide is for

HSC Health and Movement Science Focus Area 2 (Training for improved performance) is the second of two compulsory focus areas in Year 12. It builds the training-science framework students apply to a sporting context: the energy systems, the principles of training, the physiological adaptations, plus the supporting areas of skill acquisition, nutrition, monitoring, injury prevention and the ethics of performance technology.

The structure of Focus Area 2

Per the NESA Health and Movement Science 11-12 Syllabus (2023), Focus Area 2 covers nine sub-topics:

1. Principles of training and planning
2. Physiological responses and adaptations to training
3. Energy systems and training types
4. Strength, power, speed and flexibility training
5. Skill acquisition and performance improvement
6. Monitoring, recording and evaluating training and performance
7. Nutrition, hydration, supplementation and sleep for performance
8. Injury prevention, rehabilitation and return to play
9. Technology and performance enhancement; ethics and equity

Each sub-topic has its own dot-point page; this guide synthesises and highlights the marker-rewarded framings.

The training framework: principles and FITT

Specificity

Training adaptations match the imposed demand. A marathon runner who only sprints will not develop marathon endurance. The principle is also called SAID (Specific Adaptation to Imposed Demands).

Progressive overload

Adaptation requires a stimulus beyond the current capacity. Overload progresses gradually to avoid injury.

Reversibility

Gains are lost when training stops. Detraining studies show measurable decline in aerobic capacity within around 2 to 4 weeks.

Individual differences

People respond differently to identical training. Genetics, training history, recovery capacity and nutrition all contribute.

Variation

Avoid plateaus by varying training. Periodisation builds this in.

Recovery

Adaptation occurs during recovery, not during training. Insufficient recovery produces overtraining (a real clinical syndrome with both performance decline and health effects).

FITT

The prescription framework: Frequency (how often), Intensity (how hard), Time (how long), Type (which method).

Periodisation

Macro / meso / microcycle structure. Common models include linear (gradually increasing intensity, decreasing volume), undulating (mixed intensities within a week), and block (focused intensification on one capacity for weeks at a time).

Energy systems

ATP-PC system

Stored phosphocreatine resynthesises ATP for the first roughly 6 to 10 seconds of maximum effort. Anaerobic and alactic (no lactate). Recovery typically 2 to 3 minutes for full restoration.

Lactic acid system (anaerobic glycolysis)

Breaks glucose without oxygen, producing lactate. Dominates from about 10 seconds to 1 to 2 minutes. Causes the metabolic acidosis that limits sustained high-intensity effort.

Aerobic system (oxidative phosphorylation)

Uses oxygen to break down carbohydrate and fat in the mitochondria. Dominates beyond 2 to 3 minutes. Massive ATP yield per substrate molecule but slower.

Most sports use all three; the proportional contribution depends on intensity and duration. A 1500-metre track race is roughly 35 to 40 percent anaerobic and 60 to 65 percent aerobic, depending on tactics.

Physiological adaptations

Aerobic adaptations

Increased mitochondrial density and oxidative enzyme activity (cellular). Increased capillary density (tissue). Increased stroke volume and decreased resting heart rate (cardiovascular). Increased VO2 max (whole-system). Improved fat oxidation and glycogen storage (metabolic).

Anaerobic adaptations

Increased muscle creatine phosphate stores. Increased glycolytic enzyme activity. Increased neuromuscular firing rates and motor-unit recruitment. Hypertrophy (muscle cross-sectional area) for resistance training.

Flexibility adaptations

Increased range of motion at trained joints. Reduced passive tissue resistance to stretch.

Specificity applies: adaptations follow the training stimulus.

Training methods by capacity

Strength

Resistance training (3 to 5 sets of 1 to 5 reps at 85+ percent 1RM for maximal strength; 6 to 12 reps at 67 to 85 percent for hypertrophy).

Power

Plyometric training (depth jumps, box jumps); Olympic lifts; medicine-ball throws; explosive resistance work. Lower rep counts (3 to 5) at moderate-to-high load with maximum bar speed intent.

Speed

Sprint mechanics drills, resisted sprints (sleds, hill), assisted sprints (downhill, towed). Pure speed work uses full recovery (3 to 5 minutes between reps) to avoid fatigue contamination.

Endurance

Continuous training (long slow distance, tempo runs); interval training (HIIT, threshold intervals); fartlek (varied-pace). Adaptations target the aerobic system primarily.

Flexibility

Static stretching (held 20 to 30 seconds for ROM); dynamic stretching (mobility through the warm-up); PNF (proprioceptive neuromuscular facilitation, contract-relax patterns) for advanced range work.

Periodisation arranges these methods through training blocks.

Skill acquisition

Fitts and Posner stages (cognitive, associative, autonomous). Types of practice (massed vs distributed; whole vs part; blocked vs random; constant vs varied). Types of feedback (intrinsic vs extrinsic; KP vs KR; concurrent vs delayed; constant vs faded). Coaching cues (internal focus vs external focus, with external generally more effective for advanced learners). Deliberate practice (Ericsson framework: structured, feedback-rich work at the edge of current ability over years).

Monitoring training

GPS units, accelerometers, heart-rate monitors, force plates, video analysis, wellness questionnaires, RPE scales, performance testing batteries (yo-yo, beep, 1RM, vertical jump, 20m sprint). The acute-to-chronic workload ratio (ACWR) frames load management; ratios above approximately 1.5 are associated with elevated injury risk in some studies.

Nutrition, hydration, supplementation, sleep

Carbohydrate periodisation

High around training; lower on rest days for body-composition goals.

Protein

Roughly 1.6 to 2.2 g/kg/day for strength athletes; less for purely endurance athletes (still elevated above sedentary recommendations).

Hydration

Pre, during and post; sodium consideration for prolonged efforts.

Ergogenic aids

Creatine (well-evidenced for short-duration high-intensity); caffeine (well-evidenced ergogenic); beta-alanine and sodium bicarbonate for high-intensity buffering; protein supplements (convenience rather than necessity).

Sleep

7 to 9 hours for adults; often longer for athletes in heavy training. Sleep consistency matters as much as duration. Jet lag is a documented performance issue for international travel.

Injury prevention, rehabilitation, return to play

Risk factors

Intrinsic (previous injury, age, sex, biomechanics, conditioning); extrinsic (load, surface, equipment, schedule).

Prevention

FIFA 11+, RAMP, sport-specific strength and conditioning, load monitoring.

Rehabilitation phases

Acute (protection); sub-acute (range of motion); strength; sport-specific; return to play.

Return-to-play criteria

Symptom-free; strength within 10 to 15 percent of uninjured side; functional testing passed; psychological readiness. Time alone is not a sufficient criterion.

Concussion management

Recognition, immediate removal, graduated return-to-play (6-stage protocol per AFL, NRL, World Rugby and FIFA); medical clearance.

Technology and ethics

Training monitoring (legal): GPS, force plates, video, wearables, athlete management systems. Anti-doping (WADA, Sport Integrity Australia): substances prohibited at all times, in competition only, in particular sports; prohibited methods (blood doping, gene doping, sample manipulation). Athlete Biological Passport.

Technological doping debates: carbon-plate running shoes (regulated 2020 by World Athletics); LZR Racer swimsuits (banned 2010 by FINA). Ethics: athlete welfare, fair competition, informed consent, strict liability, equity of access (cost barriers, gender bias in research).

Marker advice for Focus Area 2 responses

Per NESA's general HSC marking pattern (HMS-specific guidelines pending after the 2026 exam):

• Apply the principles of training to a specific sport rather than listing generically.
• Pair an energy-system analysis with the appropriate training method.
• Name specific protocols (FIFA 11+, ACWR, periodisation models) rather than vague claims.
• Use specific Australian or international examples (AIS programs, named sports, ASADA cases).
• Acknowledge the ethical and equity dimensions of performance technology rather than treating it as univocally positive.

Connections to Focus Area 1

Focus Area 2 connects to Focus Area 1 at: physical-activity participation as a health determinant (FA1 social determinants); access to sports and physical activity infrastructure as an equity issue; digital health tools (wearables) overlapping with training-monitoring tech; the priority-populations framing applying to who has access to high-performance support. Integrated cross-focus questions in Section III draw on these connections.
