Single Leg Squat (SLS) Test

The single-leg squat test is a widely used assessment of hip and lower leg strength, as well as balance. Its purpose is to measure the strength of the lower body, particularly the quadriceps and gluteal muscle groups, and the hip stabilizer muscles. This test requires no equipment and is simple to perform.

Test Procedure

To conduct the single-leg squat test, follow these steps:

  1. Stand on one leg while lifting the other leg off the ground in front of the body, flexing the hip to approximately 45° and the knee of the non-stance leg to approximately 90°.
  2. Hold the arms straight out in front with the hands clasped together.
  3. From this position, squat down until reaching approximately 60° knee flexion, then return to the starting position.
  4. Note the leg that was tested.

Scoring and Observation

The scoring of this test usually involves the assessment of knee and hip stability. In the single-leg squat test, each player must perform five successive repetitions on each leg. Each squat is worth 15 points, with a maximum score of 75 per leg.

Variations and Alternatives

There are other tests that assess hip and thigh strength, including the wall sit test, chair stand, and the home squat test. Additionally, there are balance tests that require standing on one leg, such as the Flamingo Balance and Stork Stand Test.

This exercise/test is sometimes referred to as “pistols” and shares elements with the Trendelenburg test, which evaluates hip-abduction strength.
