1. Nature of physical education
Human movement · History of PE · Social and educational value
- 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.
- Sport and Society – Sport sociology looks at how sport and society shape each other. Physical activity runs from free play, through physical recreation, to sport, which has fixed rules, organisation and serious competition. Modern sport grew from loose local folk games: the industrial age brought written rules, clubs and governing bodies, and since about 1950 television, money and travel have made sport global and professional. Today sport, media and sponsors are tied together in a "golden triangle". Not every group takes part equally: cost, time, facilities, discrimination and stereotypes create barriers, so governments and clubs work for equal access, especially for women, disabled people, older people and low-income families. Sport also has a dark side, deviance such as doping, violence and match-fixing, which rules, testing and the law try to control. Sport can build health, identity and togetherness, but it can also divide.
2. PE and science
Sociology of sport · Psychology of sport · Exercise physiology · Biomechanics
- 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.
- 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.
- 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).
3. PE and careers
Aptitude for PE careers · Types of PE jobs · Career paths · Planning my PE career
- Career Planning: From Knowing Yourself to Your First Job – Career planning has five steps. 1) Know yourself: interests, skills and values. 2) Explore career families and find out the work, study needed, pay and demand. 3) Plan a pathway with SMART goals and a plan B. 4) Search for jobs with a CV, cover letter, digital portfolio and interview practice. 5) Make the move from school to work and keep learning, because careers change over a lifetime.
