This is a simple test of lower body muscular strength and endurance.

• purpose: to measure the strength endurance of the lower body, particularly the quadriceps muscle group.
• equipment required: smooth wall and a stopwatch

• procedure: Stand comfortably with feet approximately shoulder width apart, with your back against a smooth vertical wall. Slowly slide your back down the wall to assume a position with both your knees and hips at a 90° angle. The timing starts when one foot is lifted off the ground and is stopped when the subject cannot maintain the position and the foot is returned to the ground. After a period of rest, the other leg is tested.

• scoring: the total time in seconds that the position was held for each leg is recorded. The table below gives a general guideline to expected scores for a single leg for adults, based on my personal experiences. Comparing the scores for each leg may indicate muscle weakness on one side.

rating	males (seconds)	females (seconds)
excellent	>100	> 60
good	75-100	45-60
average	50-75	35-45
below average	25-50	20-35
very poor	< 25	< 20
