Assess The Strength of The Athlete’s Knee Flexors (Hamstrings) With Leg Curl Test

Leg Curl Test. The objective of this test is to assess the strength of the athlete’s knee flexors (hamstrings).

Required resources
To undertake this test you will require:

  • Universal knee flexor/extensor bench.

How to conduct the test

Leg Curl Test
The test is conducted as follows:
  • The athlete lies face down on the bench, knees extended, with the heels hooked behind the top of the foot pads
  • The athlete holds the front of the machine for support
  • They are to inhale as they curl up and exhale as they lower the weight
  • The final knee joint angle should be less than 90 degrees
  • As a guide, the initial resistance should be approximately 30% of male body mass and 20% 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 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 would depend upon how strict the test is conducted and the individual’s level of motivation to perform the test.

There are no published tables to relate results to potential performance in competition.
