What fitness means
Cambridge defines fitness as the ability to cope with (or meet) the demands of the environment.
Every word of that matters. The demands of the environment means whatever the performer's situation requires of them — a 90-minute football match, a 400 m swim, a hill walk in cold weather. The same person can be fit for one of those and not for another.
Fitness is specific. A performer who can meet the demands of a long-distance swim is not automatically fit enough to meet the demands of a gymnastics routine, because the demands are different.
Health and fitness are not the same thing
Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity. Fitness is the ability to cope with the demands of the environment.
They often go together, but they are not the same, and Cambridge tests the difference. Health is about the state of the whole person; fitness is about what the person can actually do.
This is why a performer can be fit but unhealthy — for example someone with a poor diet or who smokes, yet who trains hard and can meet the demands of their sport. It is also why a performer can be healthy but unfit: no illness, but no training, so the body cannot meet the demands being placed on it.
| Situation | Health | Fitness | Why |
|---|---|---|---|
| Trains hard but has a poor diet | Poor | High | Ill health does not stop them training, so fitness still increases |
| Injured and unable to train for weeks | Poor | Falling | Ill health leads to an inability to train, so fitness is lost |
| No illness but does no exercise at all | May be good | Low | Health can be present without the fitness needed to meet the demands of the environment |
| Eats a balanced diet, sleeps well and trains regularly | Good | High | A healthy, active lifestyle supports both health and fitness |
Decreased fitness because of ill health
The first half of the relationship is straightforward: ill health can lead to an inability to train, which lowers fitness.
If a performer is injured or ill, they cannot complete their training sessions, so the body stops being overloaded. The adaptations built up over months begin to be lost, and the performer can no longer cope with the same demands — a shorter run, a lower weight or a slower pace is now enough to exhaust them.
Notice the wording in the syllabus: it is the inability to train that causes the drop in fitness, not the ill health itself. That distinction is often worth a mark.
Increased fitness despite ill health
The second half is the one students find harder: a performer can be unhealthy and still increase their fitness, as long as they are able to train.
If the ill health does not prevent training — for example a poor diet, smoking, or a condition that does not restrict physical activity — then the performer can keep overloading the body and fitness will still rise. They may be able to meet the demands of their sport perfectly well even though their health is not good.
The two halves together are the point of the topic: health and fitness influence each other, but neither one automatically determines the other.
| Direction of the relationship | What happens | Effect |
|---|---|---|
| Decreased fitness because of ill health | Ill health prevents the performer from training | Fitness falls, because the training that maintains it has stopped |
| Increased fitness despite ill health | The performer is unhealthy but is still able to train | Fitness rises, because the training programme continues |
Living a healthy, active lifestyle to maintain health
The syllabus ends this section with three linked needs: live a healthy, active lifestyle, eat a balanced diet, and maintain a level of fitness to help maintain health.
The logic is circular and worth learning as a loop: a healthy, active lifestyle and a balanced diet keep the performer healthy enough to train; training maintains fitness; and maintaining fitness helps maintain health. Break one part and the others suffer.
A balanced diet provides the nutrients the body needs for energy, growth and repair — carbohydrates and fats for energy, protein for growth and repair, and water to keep the body working properly. Combined with regular activity, it helps the performer stay free from illness and able to carry out everyday tasks.
Maintaining a level of fitness matters because fitness is not permanent. Stop training and the adaptations fade, so the performer becomes less able to meet the demands of the environment — and their health can suffer too, because the body systems that exercise keeps working well are no longer being worked.
Turning knowledge into marks
A one-mark state question needs the definition: "fitness is the ability to cope with the demands of the environment."
An explain question needs the chain of cause and effect: "ill health may mean the performer cannot train, so the body is no longer being overloaded and the fitness they had built up is lost."
A longer question needs both directions of the relationship: "ill health can decrease fitness when it stops a performer training, but a performer who is unhealthy and can still train will increase their fitness — so the two are related but not the same."
Key terms you must be able to define
- Fitness
- The ability to cope with (or meet) the demands of the environment.
- Health
- A state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.
- Ill health
- Being in a state of poor health, such as illness, injury or disease; it can prevent a performer from training and so lower fitness.
- Healthy, active lifestyle
- Regular physical activity combined with habits that protect health, such as enough sleep, no smoking and sensible alcohol consumption.
- Balanced diet
- Eating the right nutrients in the right proportions — carbohydrates and fats for energy, protein for growth and repair, plus vitamins, minerals and water — to keep the body working properly.
- Maintaining a level of fitness
- Keeping up regular training so fitness does not decline, which in turn helps to maintain health.
- Training
- Planned, regular physical activity that overloads the body; it is the link between health and fitness, because ill health lowers fitness mainly by preventing training.
Applied to your sport
Cambridge requires you to apply this knowledge to physical activities. Use these as models, then write your own for the sport you play.
A swimmer who cannot train because of illness loses the adaptations built up over the season, so, when they return, the same set of lengths exhausts them — decreased fitness because of ill health.
A player with a poor diet who smokes but trains and plays twice a week can still meet the demands of a 90-minute match, because their ill health has not stopped them training — increased fitness despite ill health.
A runner who eats a balanced diet, sleeps well and trains regularly maintains both health and fitness, so they can meet the demands of a long course and keep their body systems working well.
A cyclist who is injured cannot ride for weeks, so their fitness falls; once recovered they have to rebuild their training gradually to restore fitness and help maintain their health.
A performer who keeps training regularly maintains strength and muscular endurance, so everyday tasks stay easy and the body systems continue to work well — maintaining fitness to help maintain health.

Exam technique for this topic
- Learn the fitness definition exactly: 'the ability to cope with (or meet) the demands of the environment'. 'Being fit enough to play' is not a definition.
- For questions on the relationship, always include the middle step — ill health affects fitness by preventing training. Writing only 'ill health lowers fitness' misses the mark.
- Remember that both directions are examinable: decreased fitness because of ill health, and increased fitness despite ill health.
- When asked why a healthy, active lifestyle or a balanced diet matters, give the benefit: keeping the body systems working well, staying free from illness and being able to carry out everyday tasks.
- Keep health and fitness language separate in the same answer. Health is a state of complete physical, mental and social well-being; fitness is the ability to meet the demands of the environment.
