What this dot point is asking
WJEC wants you to name and describe a standard test for each component of fitness, explain the reasons for testing, and explain reliability and validity.
Tests for each component of fitness
Learn one recognised test per component, what it measures and how it is run.
| Component | Test | What you do |
|---|---|---|
| Cardiovascular endurance | Multi-stage fitness test (bleep test) or Cooper 12-minute run | Run 20 m shuttles to faster bleeps until you cannot keep up; record the level reached |
| Muscular endurance | Sit-up test or press-up test | Count the number completed in one minute |
| Strength | Grip dynamometer | Squeeze the handgrip as hard as possible; read the force |
| Flexibility | Sit and reach test | Reach forward over a sit and reach box; record the distance |
| Power | Vertical jump (Sargent jump) | Jump as high as possible from standing; measure the height gained |
| Agility | Illinois agility run | Run a set course of turns as fast as possible; record the time |
| Speed | 30 metre sprint | Sprint 30 m; record the time |
| Reaction time | Ruler drop test | Catch a falling ruler; the distance fallen shows reaction time |
| Balance | Standing stork test | Balance on the ball of one foot; record how long you hold it |
Reasons for fitness testing
Testing is useful because it:
- shows a performer's starting level before training,
- monitors progress by comparing results before and after a training programme,
- helps set realistic targets and choose the right training,
- motivates the performer when they see improvement,
- allows comparison against normative data (national averages) for their age and sex.
Reliability and validity
Two ideas decide whether you can trust a test result.
To keep a test reliable, use the same protocol every time: the same equipment, the same instructions, the same person testing, and a warm-up beforehand. Then any change in score reflects a real change in fitness rather than a change in conditions.
Why this matters
Fitness testing links the components of fitness to a training programme. Test results show which components need work, the right methods of training are chosen, and re-testing checks whether the programme has worked. This cycle is exactly what learners do in the Unit 2 personal fitness programme.
Exam-style practice questions

WJEC style4 marksName a suitable test for cardiovascular endurance and a suitable test for flexibility, and describe how each is carried out.Show worked answer →
A 4-mark question: a mark for naming each test and a mark for describing each method.
For cardiovascular endurance, the multi-stage fitness test (bleep test) is suitable: the performer runs 20 m shuttles in time with bleeps that get faster, continuing until they can no longer keep up, and the level reached is recorded. Accept the Cooper 12-minute run as an alternative.
For flexibility, the sit and reach test is suitable: the performer sits with legs straight and feet against a sit and reach box, then reaches forward as far as possible along the ruler, and the distance reached is recorded.
Markers reward a correct named test for each component and a clear description of the method and what is measured.
WJEC style4 marksExplain what is meant by the reliability and validity of a fitness test, and why both matter.Show worked answer →
A 4-mark question: two marks for explaining reliability and two for validity.
Reliability means the test gives the same, repeatable results if it is carried out again under the same conditions. A test is reliable if the same equipment, procedure and tester are used each time, so any change in score is due to a real change in fitness. Validity means the test actually measures the component it claims to measure. For example, the sit and reach test is valid for lower back and hamstring flexibility, but it would not be a valid test of speed.
Both matter because results are only useful if you can trust them: a reliable test lets you compare before and after training fairly, and a valid test makes sure you are measuring the right component.
