Dynamic knee extension test

The objective of this test is to assess the strength of the athlete’s knee extensor muscles.

Required resources

To undertake this test you will require:

• Universal knee flexor/extensor bench.

How to conduct the test

The test is conducted as follows:

• The athlete sits on the end of the bench with the padded edge of the bench against the posterior surface of the knee joint.
• The feet are hooked behind the padded rollers. The hands grasp the sides of the bench just behind their buttocks.
• The correct technique involves a complete extension of the knee, conducted in a smooth and continuous movement.
• The initial resistance should be approximately 33% of male body mass and 25% of female body mass.
• If the athlete can successfully complete one repetition, repeat the procedure after one minute, adding an additional weight to the previous resistance.
• Continue with this procedure, allowing one minute recovery between attempts until the 1RM has been determined.
• Record the final resistance.

Analysis

Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.

Target group

This test is suitable for active athletes but not for individuals where the test would be contraindicated.

Reliability

Reliability would depend upon how strict the test is conducted and the individual’s level of motivation to perform the test.

Validity

No published tables to relate results to potential performance in competition.
