Evaluation of isometric muscular endurance of the lower limbs using a static wall-sit position.
Wall Sit Test
Test Objective
To measure the maximum duration a person can maintain a seated position against a wall (at a 90° angle), without support, in order to evaluate the muscular endurance of the quadriceps (primarily).
Test Protocol
Required Equipment:
A flat and stable wall.
A stopwatch.
Optional: A mat under the feet for comfort.
Execution Sequence:
The athlete stands with their back against the wall, feet hip-width apart, and heels positioned approximately 60 cm away from the wall.
They slide down the wall until the knees form a 90° angle, with the thighs parallel to the ground, and the back and head maintaining full contact with the wall.
The arms must be crossed over the chest or resting flat against the sides of the body (they must absolutely not rest on the thighs).
The stopwatch starts as soon as the correct holding position is achieved.
The test ends when the athlete:
Can no longer maintain the position (drops down or stands up).
Moves their hands or feet.
Loses back contact with the wall or changes the knee flexion angle.
⏱️ Result
Time maintained (in seconds).
Recorded to the nearest tenth of a second.

✅ Advantages
Very simple to implement and administer.
Requires no expensive equipment.
Provides a quick evaluation of lower limb muscular endurance.
Can be widely used in physical education, physical preparation (strength and conditioning), or rehabilitation.
⚠️ Precautions
Do not perform if the athlete experiences lower back or knee pain.
Ensure proper initial posture (strict 90° knee angle, flat back against the wall).
Strictly avoid any hand support on the legs or postural cheating.
