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.
