know the definitions of: • aerobic exercise • anaerobic exercise
Aerobic exercise is activity performed at a moderate intensity for a sustained period, where the body uses oxygen to release energy from glucose; examples include jogging and distance swimming. Anaerobic exercise is short, high-intensity activity where the body releases energy without using oxygen, such as a sprint or a heavy lift, and it cannot be sustained for long. A reliable method is to test each definition against two questions: does the activity rely on oxygen, and can it be continued for a long time? Aerobic activity can be maintained; anaerobic activity is brief and intense. Link each definition to how the body supplies energy so the distinction is clear.
be able to apply practical examples of aerobic and anaerobic activities in relation to intensity and duration.
Aerobic exercise uses oxygen to release energy over a long duration at low to moderate intensity, so a performer can keep going for many minutes; examples include distance running, cycling, swimming and a full football match. Anaerobic exercise releases energy without oxygen at high intensity for a short duration, so it cannot be sustained; examples include a 100 m sprint, a heavy weightlifting set, a fast break in basketball or a tennis rally of a few seconds. To apply the idea, judge each activity by how hard it is and how long it lasts: long and moderate points to aerobic, short and explosive points to anaerobic. Many sports mix both, such as a football match (aerobic) containing sprints (anaerobic).
Your focus
- State the definition of aerobic exercise.
- State the definition of anaerobic exercise.
- Distinguish aerobic from anaerobic activity using oxygen use, intensity and duration.
Show all 6 objectives
- Classify given activities as aerobic or anaerobic using intensity and duration.
- Explain why an activity is aerobic or anaerobic in terms of oxygen supply.
- Apply both concepts to a mixed sport by separating its phases.
1.1.d. The cardiovascular and respiratory systems - Aerobic and anaerobic exercise exam tips
Marking Points
- Defines aerobic exercise as activity using oxygen to release energy over a sustained period.
- Defines anaerobic exercise as short, high-intensity activity releasing energy without oxygen.
- Distinguishes the two by duration and intensity.
- Gives a correct example of aerobic or anaerobic activity.
- Identifies a long-duration, moderate-intensity activity such as distance running or swimming as aerobic because oxygen supply meets demand.
- Identifies a short-duration, high-intensity activity such as a 100 m sprint or a heavy lift as anaerobic because oxygen supply cannot meet demand.
- Explains that aerobic activity can be sustained for many minutes while anaerobic activity lasts only seconds.
- Applies intensity and duration together to classify a mixed sport, for example a football match as mainly aerobic with anaerobic sprints.
Examiner Tips
- 💡Include both the role of oxygen and the duration or intensity in each definition.
- 💡Use a contrasting pair of examples, such as a marathon run and a 100 m sprint.
- 💡Check that the definition answers the term asked, not just its example.
- 💡Read the activity and ask two questions: how hard, and how long? Use both to decide.
- 💡Link each answer to oxygen supply meeting or not meeting demand, not just to the name of the sport.
- 💡For mixed sports, name the aerobic phase and the anaerobic phase separately.
Common Mistakes
- Defines anaerobic exercise as exercise without breathing at all; correct this by stating that energy is released without using oxygen.
- Treats a long slow run as anaerobic; correct this by classifying sustained moderate activity as aerobic.
- Gives only an example without a definition; correct this by stating what each term means.
- Labels any sport as purely aerobic or purely anaerobic; recognise that many sports combine both depending on the phase of play.
- Classifies a long slow jog as anaerobic; match the label to low intensity and long duration, which is aerobic.
- Classifies a short explosive sprint as aerobic; match the label to high intensity and short duration, which is anaerobic.
