1. Management of Sporting Events

Sports event management

Sports Management: Organising Sport – Sports management means planning, organising, leading and checking sport so that people can play safely and enjoy it. To organise an event: set a clear goal and answer who, what, when and where; choose a format (knockout, round-robin, league or a mix) and work out fixtures and time; share roles and track tasks on a checklist or app; make a budget and a risk plan; run the event; then evaluate and report so next time is better (plan → do → check → improve). Sport itself is organised at many levels, from school and club to regional, national and international federations, with government sport policy and different forms such as clubs, commercial gyms, school sport and informal play.

Children and women in sports

Posture and Physical Development – Posture is the way you hold your body when you stand, sit or move. In good standing posture the ear, shoulder, hip, knee and ankle sit on one straight up-and-down line (the line of gravity). The spine has three gentle curves (neck, upper back, lower back) that make a soft S and act like a spring. Common faults are round back (kyphosis), hollow back (lordosis), flat back, sideways curve (scoliosis) and forward head (text neck). Mild faults can be prevented and corrected with stretching, strengthening, aerobic and light-resistance exercise, good habits and regular checks of growth (height, mass, BMI) and body functions (heart rate, breathing rate, blood pressure, recovery).

Yoga for lifestyle diseases

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.

Disability sports

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.

Sports nutrition

Sports Nutrition: Energy, Diet and Hydration – Athletes need the right food and water at the right time. Energy in (food) must match energy out (exercise plus body work) to keep weight steady. Carbohydrates are the main fuel and are stored as glycogen; protein repairs muscle; fat fuels long, slow work; vitamins, minerals and fibre keep the body working. Losing about 2% of body mass as sweat lowers performance, so athletes drink before, during and after exercise. Most supplements are not needed with a good diet, and banned drugs (doping) are unsafe and against the rules.

Fitness testing

Fitness Testing: How We Measure Each Part of Fitness – A fitness test measures one component of fitness and gives a number. Each component has its own test: the multi-stage beep test for stamina, hand grip for strength, sit and reach for flexibility, a 30 m sprint for speed, the Illinois run for agility, jumps for power, the stork stand for balance, the ruler drop for reaction time and BMI for body composition. A good test is valid and reliable. Results are compared with norms and with your own earlier scores, tracked with simple devices, and used to plan training, including for job recruitment tests.

Exercise physiology

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.

Biomechanics in sports

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.

Sports training methods

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).
