Kraus-Weber Abdominal Strength Test 2

Home   /  Kraus-Weber Abdominal Strength Test 2

The test is part of the Kraus-Weber fitness test protocols, a series of six medical fitness test measures the strength and flexibility of key postural (core) muscles. This abdominal test assesses the strength of the abdominal muscles - with minimizing the use of the psoas muscles.

Purpose: To assess the strength of the abdominal muscles.

Equipment Required: Flat surface.

Procedure: The lying position for this test is the same as the first K-W test - the subject lies down in a supine position flat on his back and hands behind his neck, except that this time the knees are bent. The examiner holds the feet to keep them on the ground. The subject is required to perform one sit-up. If he is able to perform a full sit-up, he passes this test. If he is unable to raise his shoulders from the table or ground, the score is zero.

Scoring: This test is graded on a pass-fail basis. The Kraus-Weber test comprises 6 exercises - being unable to perform even one of the six exercises results in failing the test.

Advantage: This is a very simple test to conduct, can be quickly performed with minimal equipment.

Comments: The difference between this test and the first Kraus-Weber Abdominal Strength Test is that in this case the knees are held in a bent position.
