Physical Education (Category A Elective): Concepts, Application and Exam Technique
Physical Education is a Category A elective assessed through written theory papers - multiple-choice, short and structured questions - plus a school-based practical component in which you perform, and then analyse, your own activity. The written papers do not reward memorised lists alone: most marks sit in questions that hand you a concept (a training principle, an energy system, a lever, a sociological definition) and ask you to apply it to a named performer in a named activity, then justify the choice.
Definitions examiners expect you to state precisely
- Play is freely chosen, intrinsically motivated and consequence-free; game adds rules and competition; sport adds institutionalised organisation, physical skill and public comparison; recreation is activity chosen for restoration or enjoyment and need not be physical.
- Health-related fitness: cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, body composition. Skill-related fitness: speed, agility, balance, coordination, power, reaction time. Power belongs to the skill-related list, never the health-related one.
Training: FITT and the principles that earn marks
Frequency, intensity, time, type, then overload, specificity, progression, reversibility, recovery, individuality and diminishing returns. Always name the variable you changed - "intensity rose from 70% to 80% of heart-rate reserve" - rather than "trained harder".
Energy systems in one line each
ATP-PCr: roughly 0–10 s, maximal intensity, no oxygen, no lactate. Anaerobic glycolysis: about 10 s to 2 min, lactate accumulates and limits performance. Aerobic: beyond 2 min, oxygen-dependent, highest ATP yield, sustainable at moderate intensity.
Worked example
A 20-year-old with a resting heart rate of 60 bpm is prescribed a 70% aerobic session.
- HRmax ≈ 220 − 20 = 190 bpm.
- Heart-rate reserve = 190 − 60 = 130 bpm.
- Target = (130 × 0.70) + 60 = 151 bpm. Reasoning: the Karvonen method scales the reserve, not the maximum. Using 190 × 0.70 = 133 bpm omits resting heart rate and under-prescribes the session; the answer must also state that the intensity is specific to aerobic development and progressive once 151 bpm is tolerated comfortably.
Traps that cost marks
- Treating 220 − age as exact; it is an estimate with roughly ±10–12 bpm individual error.
- Swapping muscular strength (maximal force, few repetitions) with muscular endurance (repeated submaximal contractions).
- Forgetting that a biceps curl is a third-class lever: effort between fulcrum and load, so mechanical advantage is below 1 and the muscle trades force for speed and range.
- Giving a definition with no sporting example, or an example with no principle named - HKDSE questions reward the pairing.
- Describing overload as "lifting heavier" only; overload is any increase beyond the habitual load, including volume, frequency or reduced rest.
