Well-being
Physical, emotional & social well-being
Health is complete physical, mental and social well-being, not just the absence of illness. Regular activity benefits all three:
Physical — stronger heart and muscles, healthy weight, lower disease risk.Emotional (mental) — less stress, better mood, more confidence.Social — friendship, teamwork and a sense of belonging.
Quick check
Which benefit?
? Someone says that going for a run clears their head and reduces their stress. Which type of well-being is this?
Physical ❌
Emotional (mental) ✅
Social only ❌
None of these ❌
Sedentary lifestyle
The sedentary lifestyle
A sedentary lifestyle means very little activity. Over time it raises the risk of:
weight gain and obesity ;
coronary heart disease and high blood pressure;type 2 diabetes ;weaker bones and muscles, poorer posture and lower fitness.
Quick check
Consequence of inactivity
? Which is a genuine long-term risk of a sedentary lifestyle?
Increased flexibility ❌
Increased risk of type 2 diabetes ✅
Stronger heart automatically ❌
Faster reaction time ❌
Diet
A balanced diet & energy balance
A balanced diet provides the right nutrients in the right amounts:
Carbohydrates — the main energy source for exercise.Proteins — growth and repair of muscle and tissue.Fats — energy store and insulation (in moderation).Vitamins & minerals — e.g. calcium for bones, iron for red blood cells.Fibre and water — digestion and hydration.
Energy balance: energy in = energy out keeps weight stable; a surplus is stored as fat.
Sort it
Put each one in the right group
Tap a food or its job, then tap the nutrient group it belongs to.
BMI
Body Mass Index (BMI)
BMI = mass (kg) ÷ height² (m²)square the height first, then divide the mass by it
Worked example
Mass = 70 kg , height = 1.75 m . height² = 3.0625.
BMI = 70 ÷ 3.0625 = 22.9 .
Limitation: BMI can't tell muscle from fat, so a muscular athlete may score "overweight" despite low body fat.
Calculate
Calculate BMI
1 A performer has a mass of 64 kg and a height of 1.6 m . Calculate their BMI to one decimal place. (height² = 1.6 × 1.6 = 2.56)
Check ✓
Hint: BMI = 64 ÷ 2.56.
Calculate
BMI again
2 An adult has a mass of 90 kg and a height of 2.0 m . Calculate their BMI. (height² = 2.0 × 2.0 = 4.0)
Check ✓
Hint: BMI = 90 ÷ 4.0.
Quick check
BMI limitation
? A very muscular rugby prop has a high BMI but low body fat. What does this show about BMI?
BMI is always wrong ❌
BMI cannot tell muscle from fat, so it can mislead for muscular people ✅
The prop must be unhealthy ❌
BMI measures fitness directly ❌
Match it
Match each statement to its answer
Tap a nutrient or term on the left, then its correct job on the right.
Recap
The big ideas to know
Well-being: physical, emotional (mental) and social benefits of activity
Sedentary lifestyle: obesity, coronary heart disease, high blood pressure, type 2 diabetes
Diet: carbohydrate (energy), protein (repair), fats, vitamins, minerals, fibre, water
Energy balance: in = out → stable weight; surplus stored as fat
BMI: mass (kg) ÷ height² (m²) — can't tell muscle from fat
