You need to justify your choice of tests by commenting on their suitability, reliability, validity, and practicality. An example is given of justifying the grip dynamometer test, noting that it is suitable for all sports, reliable if calibrated for each individual, its validity to measure general strength has been questioned as forearm strength does not represent other muscles, and it is practical as it is quick with limited equipment needs.

2. SELECTING THE TESTS
You have selected and administered most of your tests for your client, in
your feedback you will need to justify your choice of tests. To do this
you will need to comment on the following:
• Suitability
• Reliability
• Validity
• Practicality
There is an example on the next slide

3. GRIP DYNAMOMETER
Suitability: the test is suitable for all sports and can be conducted
anywhere as long as there is a handgrip dynamometer
Reliability: to make sure the test is reliable the dynamometer must be
calibrated for each individual to ensure the results are consistent
Validity: the validity of this test to measure general strength has been
questioned as the strength of the forearm muscles does not represent
the strength of other muscle groups
Practicality: the test is practical as it is quick to administer and limited
equipment is required. Also individuals can compare their results with
normative data which will reflect if they have improved strength or not
