Changing trends and careers

Physical Education: Learn, Analyse and Improve a Skill – Physical education (PE) teaches you to move well, stay active for life and understand your own performance. Every sports skill has three phases: preparation, execution and follow-through. To improve, you observe the skill, compare it with a model, find strengths and weaknesses, get feedback and plan practice: plan → do → review → feedback. People are active for health, fitness, fun, friends, competition and well-being. Trying new and alternative sports, joining clubs, staying safe and looking after equipment help you keep moving all your life.

Olympism and the Olympic movement

The Olympic Movement – The ancient Olympic Games began at Olympia in Greece, traditionally in 776 BCE, as a religious festival for Zeus held every four years. Free Greek men competed in running, wrestling, boxing, chariot racing and the pentathlon; winners received an olive wreath, and a truce let athletes travel safely. The games ended around 393 CE. Pierre de Coubertin founded the International Olympic Committee (IOC) in 1894 and the first modern Games took place in Athens in 1896. Today the Olympic Movement includes the IOC, international sports federations and National Olympic Committees. Its symbols are the five rings, the flame and the motto "Faster, Higher, Stronger – Together"; its values are excellence, friendship and respect. The Paralympic Games follow in the same host city.

Yoga

Yoga: Body, Breath and Mind Together – Yoga means union: it joins body, breath and mind. Ashtanga yoga has 8 limbs: yama, niyama, asana, pranayama, pratyahara, dharana, dhyana, samadhi. Asanas are steady, comfortable postures; pranayama is breath control (inhale–hold–exhale); shatkarmas are six cleansing practices. Regular yoga improves flexibility, strength, balance, concentration and mood, lowers stress, and helps prevent and manage lifestyle diseases such as obesity, diabetes, asthma, hypertension, back pain and arthritis, always with the right cautions.

Adaptive physical education

Inclusive Sport: How Everyone Gets to Play – Inclusive sport means everyone can take part — whatever their ability, gender, body, background or money. Barriers can be physical (steps, no ramps), in the rules or equipment, or in people's attitudes (teasing, exclusion, violence). We remove them by building access, adapting games with the STEP model (Space, Task, Equipment, People), writing fair rules for all, and calling out harmful behaviour. Paralympic and adapted sports show how far this can go.

Fitness and wellness

Physical Fitness – Physical fitness is the body's ability to do daily work, play and sport with energy to spare. It has five health-related components (heart-lung endurance, muscular strength, muscular endurance, flexibility, body composition) and six skill-related ones (speed, agility, power, balance, coordination, reaction time). We improve it with a planned programme using FITT (frequency, intensity, time, type) and training principles like overload, progression, specificity, rest and reversibility.

Test and measurement

Body Mass Index (BMI) and Body Measurements – Body Mass Index (BMI) is your mass in kilograms divided by your height in metres, squared. It gives one number that sorts adults into underweight, healthy, overweight or obese. Coaches also use waist-hip ratio, skinfold thickness and body type (somatotype) to understand the body. These are tests and measurements; evaluation means judging what the numbers say.

Anatomy and physiology in sports

Exercise Physiology – Exercise physiology studies how the body works during and after physical activity. When we exercise, working muscles need more ATP and oxygen, so heart rate, stroke volume, breathing rate and depth rise. ATP is remade by three energy systems: ATP-PC (about 10 s), anaerobic glycolysis (up to about 2 min, makes lactate) and aerobic (long efforts, uses oxygen). Cardiac output = heart rate × stroke volume. Regular training strengthens the heart, lungs, muscles and bones; ageing slowly reduces these, but exercise slows the decline.

Kinesiology and biomechanics

Sports Biomechanics – Biomechanics is the physics of the moving body. Movement happens in three planes (sagittal, frontal, transverse) around three axes. Bones, joints and muscles work as levers: a pivot, an effort and a load. Most body levers are third class: they give little force but fast, wide movement. Newton's three laws explain starting, speeding up and pushing off the ground; friction gives grip. Stability depends on the centre of gravity, the base of support and the line of gravity. Turning movements follow the same ideas: torque starts a spin, and with no outside torque angular momentum stays the same, so pulling the arms in makes you spin faster. A thrown ball, javelin or jumper is a projectile: speed, angle and release height set the distance. Air and water push back with drag; spin and shape can create lift (the Magnus effect).

Sports psychology

Sports Psychology: The Mind Behind the Performance – Sports psychology studies how the mind affects play. Personality shapes how we like to train. Motivation is the fuel: from inside (fun) or outside (prizes). Arousal is how "switched on" you are: too little or too much hurts, the middle is best (inverted U). Anxiety is worry; breathing, imagery and positive self-talk calm it. SMART goals give a clear ladder. Aggression must be controlled, and teams work best when everyone pulls together.

Training and doping

Sports Training: Principles and Methods – Sports training is planned exercise that makes the body fitter for a sport. Every session has a warm-up (raise heart rate, temperature and flexibility slowly), the main work and a cool-down (bring the heart rate down and remove waste such as lactic acid). Good training follows principles: Specificity (train for your sport), Progression and Overload (do a little more over time so the body adapts), Reversibility (fitness is lost when you stop) and Tedium (vary training to avoid boredom), plus rest and recovery. FITT sets the dose: Frequency, Intensity, Time, Type. Intensity can be measured with heart rate: maximum heart rate ≈ 220 − age; 60–80% trains the aerobic system and 80–90% the anaerobic system. Main methods are continuous, interval, fartlek, circuit, weight (resistance), plyometric and flexibility training. A training year can be split into pre-season, competition and off-season phases (periodisation).
