Planning in Sports
Key Points to Remember
- →Knock-out tournament: loser eliminated. Total matches = N − 1 (N = total teams). Byes = next power of 2 − N.
- →League (Round Robin) tournament: each team plays every other team. Matches = N(N−1)/2.
- →Combination tournament: knock-out + league stages combined.
- →Fixture drawing (knock-out): upper half = ⌈N/2⌉ teams, lower half = ⌊N/2⌋. Byes distributed to lower half first.
- →Seeding: top teams placed to avoid early confrontation. Seeds placed in standard positions (1st seed: top of upper, 2nd seed: bottom of lower, etc.).
- →Intramural: within the school. Extramural: between two or more schools.
- →Sports meet organisation: technical committee, ground preparation, officials (referee, umpire, linesman, scorer), awards ceremony.
Exam Tips
Always draw the actual fixture bracket for the given number of teams — asked as a diagram.
Byes calculation: for 11 teams → next power of 2 = 16, byes = 16−11 = 5.
Number of rounds in knockout = log₂(next power of 2 for N).
Sports and Nutrition
Key Points to Remember
- →Macro nutrients: Carbohydrates (primary energy — 4 kcal/g), Proteins (muscle repair — 4 kcal/g), Fats (sustained energy, fat-soluble vitamins — 9 kcal/g).
- →Micro nutrients: Vitamins (A, B-complex, C, D, E, K) and Minerals (Ca, Fe, K, Na, Zn) — no energy but essential for body functions.
- →Balanced diet: all nutrients in right proportion. Recommended dietary allowance (RDA) varies by age, sex, activity level.
- →Nutritive components: carbohydrates, proteins, fats, vitamins, minerals, water.
- →Non-nutritive components: dietary fibre (roughage), pigments, flavour compounds, antioxidants.
- →Eating disorders: Anorexia Nervosa (fear of weight gain, refusal to eat), Bulimia Nervosa (binge-eating + purging), Binge Eating Disorder.
- →Sports nutrition: pre-event (complex carbs, hydration), during (electrolytes, simple carbs), post-event (protein for repair, carbs for glycogen replenishment).
Exam Tips
Proteins: complete (animal — all essential amino acids) vs incomplete (plant — missing some).
Fats: saturated (animal, solid at room temp) vs unsaturated (plant, liquid at room temp).
Athlete's plate: 50% carbs, 25% proteins, 25% vegetables/fruits (general guideline).
Yoga and Lifestyle
Key Points to Remember
- →Diabetes: Bhujangasana (strengthens pancreas), Vajrasana (aids digestion after meals), Mandukasana (abdominal organs), Matsyasana, Dhanurasana.
- →Hypertension: Tadasana (balances nervous system), Vajrasana, Pawan Muktasana, Shavasana (deep relaxation).
- →Obesity: Trikonasana (lateral stretch), Ardha Matsyendrasana (spinal twist, abdominal organs), Dwi-pada-uttanasana, Halasana.
- →Back pain: Halasana (stretches spine), Shalabhasana (strengthens back muscles), Makarasana (rest position), Bhujangasana, Uttanpadasana.
- →Asthma: Sukhasana (relaxes breathing), Chakrasana (opens chest), Gomukhasana, Parvatasana, Anulom Vilom (pranayama).
- →Each asana: know the procedure (step-by-step), benefits, and contraindications (when NOT to do it).
Exam Tips
Vajrasana: only asana that can be done immediately after meals — good exam fact.
Shavasana (Corpse Pose): used for complete relaxation — often recommended for hypertension and stress.
Contraindications always asked: e.g., Bhujangasana — avoid in pregnancy, herniated disc.
Physical Education and Sports for CWSN
Key Points to Remember
- →CWSN: Children With Special Needs. Inclusive education: mainstream education with required support.
- →Types of disability: Visual (blindness, low vision), Hearing (deaf, hard of hearing), Locomotor (orthopaedic impairment), Intellectual (cognitive limitations).
- →Adapting activities: modified rules, adapted equipment, peer support, multi-sensory instructions.
- →Paralympic Games: quadrennial games for athletes with disabilities. Organised by IPC (International Paralympic Committee).
- →Disability etiquette: person-first language ('person with disability', not 'disabled person'), ask before helping, maintain eye contact.
- →Special Olympics: for athletes with intellectual disabilities. Year-round sports training and competition.
Exam Tips
Paralympics vs Special Olympics: Paralympics = all physical disabilities; Special Olympics = specifically intellectual disabilities.
IPC: International Paralympic Committee — based in Bonn, Germany.
Locomotor disability in sport: wheelchair basketball, blind cricket use adapted rules.
Children and Women in Sports
Key Points to Remember
- →Motor development in children: sequence is universal (cephalocaudal — head to toe; proximodistal — trunk to extremities).
- →Physical activity guidelines for children (WHO): at least 60 minutes of moderate-to-vigorous activity daily.
- →Overuse injuries in children: stress fractures, Osgood-Schlatter disease (knee), growth plate (epiphyseal plate) injuries.
- →Barriers for women in sports: sociocultural (traditional gender roles), economic (lack of sponsorship), infrastructural (fewer women-specific facilities), psychological (lack of confidence).
- →Female Athlete Triad: 1. Disordered eating (low calorie intake), 2. Amenorrhoea (loss of menstrual cycle), 3. Osteoporosis (low bone density).
- →Gender equity: equal opportunity regardless of gender. Title IX (USA) — landmark legislation for gender equality in school sports.
Exam Tips
Female Athlete Triad: all three components are interconnected — low energy → hormone disruption → bone loss.
Growth plate injuries most common in adolescents — growing cartilage at ends of long bones is vulnerable.
Women in Indian sports: PV Sindhu, Saina Nehwal, Mary Kom, Mirabai Chanu — can be used as examples.
Test, Measurement and Evaluation in Sports
Key Points to Remember
- →Test: standardised instrument. Measurement: process of collecting data using a test. Evaluation: interpreting measurement data against norms/standards.
- →Harvard Step Test: step up and down a 20-inch bench for 5 minutes. Count pulse at 1–1.5, 2–2.5, 3–3.5 minutes after exercise. Fitness Index = 30,000 / Σ(3 pulse counts).
- →Fitness Index interpretation: <55 = poor; 55–64 = low average; 65–79 = high average; 80–89 = good; ≥90 = excellent.
- →Rockport Walk Test: walk 1 mile as fast as possible. Record heart rate at finish. Estimate VO₂ max using formula.
- →Barrow Three-Item Motor Ability Test: (1) Standing Broad Jump, (2) Zig-Zag Run, (3) Medicine Ball Put.
- →Rikli and Jones Senior Citizen Fitness Test (6 items): Chair Stand Test (lower body strength), Arm Curl Test, 6-Minute Walk, 2-Minute Step, Chair Sit and Reach, Back Scratch Test.
Exam Tips
Harvard Step Test formula: 30,000 / (sum of pulse counts at 3 intervals × 2).
Difference: test = tool; measurement = process; evaluation = judgement — know the definitions.
Motor fitness components tested by Barrow: strength (broad jump), agility (zig-zag), explosive power (medicine ball).
Physiology and Sports
Key Points to Remember
- →Cardiovascular adaptations (long-term): cardiac hypertrophy (enlarged heart), increased stroke volume, decreased resting heart rate (athlete's heart: ~40–50 bpm), increased VO₂ max.
- →Respiratory adaptations: increased vital capacity, increased tidal volume during exercise, more efficient gas exchange.
- →Immediate exercise effects: increased heart rate, increased respiration rate, increased blood flow to muscles, sweating.
- →VO₂ max: maximal oxygen consumption. Best indicator of aerobic fitness. Improved by aerobic training (running, cycling, swimming).
- →Oxygen debt (EPOC): excess post-exercise oxygen consumption. Repays 'oxygen debt' incurred during high-intensity exercise.
- →Muscle fibre types: Type I (slow-twitch) — fatigue-resistant, aerobic, endurance (marathon runner). Type II (fast-twitch) — high power, anaerobic, sprint (sprinter).
- →Energy systems: ATP-PC system (0–10 sec, sprinting), Lactic acid/glycolytic (10 sec–2 min), Aerobic oxidative (>2 min, long distance).
Exam Tips
VO₂ max in trained athletes can be 70–85 mL/kg/min vs untrained ~35–45 mL/kg/min.
Cardiac hypertrophy in athletes: physiological (healthy, enlarged but functional). Pathological hypertrophy is disease.
EPOC: after exercise, body needs extra O₂ to restore ATP, eliminate lactic acid, normalise body temperature.
Biomechanics and Sports
Key Points to Remember
- →Newton's 1st law (Inertia): body at rest stays at rest; body in motion stays in motion unless acted on by external force. Application: a static athlete needs greater force to start moving.
- →Newton's 2nd law (Acceleration): F = ma. Greater force → greater acceleration. Application: greater muscular force → faster sprint start.
- →Newton's 3rd law (Action-Reaction): every action has equal and opposite reaction. Application: swimmer pushes water back → moves forward.
- →Levers in body: 1st class (fulcrum between effort and resistance) — head/neck extension. 2nd class (resistance between fulcrum and effort) — calf raise, wheelbarrow. 3rd class (effort between fulcrum and resistance) — bicep curl, throwing. Most common type in body is 3rd class.
- →Projectile motion: path is parabolic. Range = v²sin(2θ)/g. Maximum range at 45°. Height maximum at 90°.
- →Centre of gravity: point where total body weight acts. Lower CoG → greater stability. Wider base → greater stability.
- →Friction: static > kinetic. Sports shoes use tread pattern to maximise friction (grip). Swimmers use smooth suits to minimise.
Exam Tips
Lever class identification: know which is fulcrum, effort, and load in each example.
Projectile: javelin at 45° for max range only if launched from ground level. In practice, launch height matters.
Stability: stability = (base of support) / (height of CoG). Wider stance + lower CoG = most stable.
Frequently Asked Questions
Are these notes based on 2025-26 CBSE syllabus for Class 12 Physical Education?
Yes. All chapter notes here are based on the latest 2025-26 CBSE syllabus for Class 12 Physical Education. Deleted topics are clearly marked so you focus only on what will be tested in your board exam.
How to study Class 12 Physical Education notes effectively for board exams?
Read each chapter's notes once to build understanding. Then close the notes and try to recall every key point, definition, and formula from memory. Anything you miss is your weak area — revisit only those points. This active recall method takes less time and retains far more than re-reading.
What is the difference between NCERT notes and chapter summaries?
Chapter notes contain detailed definitions, key terms, formulas, and concept breakdowns — they're for learning and understanding. Chapter summaries are shorter paragraph-style overviews — they're for quick revision. Use notes when you're studying a chapter for the first time; use summaries the night before the exam.
Do I need to memorise formulas for Class 12 Physical Education CBSE board exam?
Yes. Formulas listed in these notes must be memorised precisely — CBSE doesn't give formula sheets during exams. Write each formula 5–10 times, then recall it without looking. In the exam, write the formula first, then substitute values — this helps you earn partial marks even if the final answer has a calculation error.
