Health, fitness and wellbeing (Section 3.2.3) is the final section of Paper 2. It covers the physical, emotional, and social benefits of an active lifestyle, the consequences of a sedentary lifestyle, the role of diet and nutrition in performance, somatotypes, and the links between diet and specific types of performers. This section regularly provides extended response questions, particularly on the consequences of sedentary lifestyles and the importance of diet for different performers.

These three terms are frequently confused. AQA requires you to know the precise definitions and understand the differences.
| Term | Definition | Key Point |
|---|---|---|
| Health | A state of complete physical, mental, and social wellbeing, and not merely the absence of disease or infirmity (WHO definition) | Health is more than just "not being ill" — it includes mental and social dimensions |
| Fitness | The ability to meet the demands of the environment | A footballer must be fit enough to run, sprint, jump, and tackle for 90 minutes |
| Wellbeing | A state of physical, social, and mental wellness — a holistic sense of feeling good about yourself and your life | Wellbeing encompasses happiness, life satisfaction, and a sense of purpose |
Physical activity can improve all three, but they are distinct concepts:
Exam Tip: "Define the term 'health'" is one of the most common 1–2 mark questions. You must include all three elements: physical, mental, AND social wellbeing. Writing only "not being ill" will score zero — you need the full WHO definition.
| Benefit | Explanation |
|---|---|
| Improved cardiovascular fitness | The heart becomes stronger and more efficient, reducing the risk of coronary heart disease |
| Improved muscular strength and endurance | Muscles become stronger and can work for longer periods |
| Weight management | Regular exercise burns calories, reducing the risk of obesity |
| Improved flexibility | Regular stretching and movement maintains or improves range of motion at joints |
| Stronger bones | Weight-bearing exercise increases bone density, reducing the risk of osteoporosis |
| Improved immune system | Moderate exercise enhances immune function, reducing susceptibility to illness |
| Reduced risk of type 2 diabetes | Exercise improves insulin sensitivity and helps regulate blood sugar levels |
| Improved body composition | Regular activity reduces body fat percentage and increases lean muscle mass |
| Benefit | Explanation |
|---|---|
| Reduced stress and anxiety | Exercise releases endorphins (natural mood elevators) and provides a distraction from daily worries |
| Improved self-esteem and confidence | Achieving fitness goals and improving physical appearance boosts self-image |
| Improved mood | Endorphin release creates feelings of happiness and positivity ("runner's high") |
| Better sleep | Regular physical activity promotes deeper, more restorative sleep |
| Reduced risk of depression | Exercise has been shown to be as effective as medication for mild to moderate depression |
| Sense of achievement | Completing a training session or reaching a personal best provides satisfaction |
| Improved concentration | Regular exercise improves blood flow to the brain, enhancing cognitive function |
| Benefit | Explanation |
|---|---|
| Making friends | Team sports and group activities provide opportunities to meet new people |
| Teamwork and cooperation | Working with others towards a common goal develops interpersonal skills |
| Sense of belonging | Being part of a team or club creates a community and identity |
| Communication skills | Sport requires communication — calling for the ball, giving instructions, supporting teammates |
| Leadership opportunities | Captaining a team or coaching develops leadership skills |
| Social inclusion | Adapted sports programmes enable people with disabilities to participate alongside peers |
Exam Tip: Questions on benefits of physical activity often specify "physical, emotional/mental, and social benefits." Make sure your answer includes at least one benefit from each category. Writing only about physical benefits when the question asks for all three will cost you marks.
A sedentary lifestyle is one involving little or no physical activity. In modern society, many people spend long periods sitting — at desks, in cars, and in front of screens.
| Consequence | Explanation | Link to PE Knowledge |
|---|---|---|
| Obesity | Consuming more calories than expending leads to weight gain over time | Excess body fat (high body fat percentage) — poor body composition |
| Coronary heart disease (CHD) | Lack of exercise weakens the heart muscle and allows cholesterol to build up in arteries | The heart does not undergo the beneficial adaptations of regular training (cardiac hypertrophy, lower resting HR) |
| Type 2 diabetes | Inactivity reduces insulin sensitivity, meaning the body struggles to regulate blood sugar levels | Regular exercise improves insulin sensitivity |
| Hypertension (high blood pressure) | Lack of exercise leads to stiffer arteries and a less efficient heart | Regular exercise improves arterial elasticity and cardiac efficiency |
| Osteoporosis | Without weight-bearing exercise, bones lose density and become weaker | Regular exercise increases bone density |
| Poor posture | Sitting for long periods weakens core muscles and tightens hip flexors | Can lead to back pain and reduced range of movement |
| Depression and anxiety | Lack of exercise reduces endorphin production and social interaction | Regular exercise improves mental health through endorphin release and social benefits |
| Loss of muscle tone | Without regular use, muscles atrophy (reduce in size and strength) | The principle of reversibility — fitness gains are lost when training stops |
| Increased risk of stroke | Poor cardiovascular health increases the risk of blood clots | Regular exercise improves blood flow and reduces clotting risk |
| Reduced life expectancy | The combined effects of obesity, CHD, diabetes, and other conditions reduce lifespan | An active lifestyle is one of the strongest predictors of longevity |
Obesity is defined as having a BMI of 30 or above, or an excessively high body fat percentage.
| Factor | How It Contributes to Obesity |
|---|---|
| Sedentary lifestyle | Fewer calories burned through physical activity |
| Poor diet | High intake of sugar, saturated fat, and processed foods |
| Large portion sizes | More calories consumed per meal than the body needs |
| Convenience food | Fast food and ready meals are often high in calories and low in nutrients |
| Screen time | Encourages sitting and is often accompanied by snacking |
| Reduced active transport | Driving instead of walking or cycling |
Exam Tip: "Discuss the consequences of a sedentary lifestyle" is one of the most frequently examined extended response questions on Paper 2. For a top-level answer: (1) define sedentary lifestyle, (2) discuss at least four consequences in detail (not just list them), (3) explain HOW inactivity leads to each consequence, and (4) link to PE knowledge (e.g. reversibility, body composition, cardiovascular fitness).
Macronutrients are needed in large amounts and provide energy.
| Macronutrient | Function | Sources | Role in Sport |
|---|---|---|---|
| Carbohydrates | The body's primary energy source; stored as glycogen in muscles and liver | Bread, pasta, rice, potatoes, cereals, fruit | Endurance performers need high carbohydrate diets to maintain glycogen stores for sustained energy |
| Proteins | Growth and repair of muscle tissue; also used for energy when carbohydrate stores are depleted | Meat, fish, eggs, dairy, beans, lentils, nuts | Strength and power athletes need protein for muscular hypertrophy and recovery after training |
| Fats | Secondary energy source; insulation; protection of vital organs; absorption of fat-soluble vitamins | Butter, oils, cheese, nuts, avocado, fatty fish | Endurance performers use fat as an energy source during long-duration, low-intensity exercise |
Micronutrients are needed in small amounts but are essential for body functions.
