Test Description: The Single Leg Squat For Time Test is a reliable tool developed and used to evaluate lower body performance, muscle power, and muscle endurance. Please watch the video to get a visual demonstration of how to perform the test. Below you will find a description of how to do so.
Test Instructions: Get set-up sitting on the edge of a stable surface that ideally makes your thighs parallel to the ground. Lift one leg off the ground and keep it in the air in front of you the entire time, you will perform the test on both sides. Using a stopwatch or something to keep track of time, the test begins as soon as you lift up from the surface to perform your first single-leg squat. Your final score is the total number of quality single leg squats in 1 minute. Perform on the other side, write down your scores below.
Some rules to remember with this assessment. One quality repetition counts as fully standing up and squatting back down until your bottom touches the surface with good form. Be sure to reference the resource video, "compensations with the single-leg squat for time test" after performing this assessment on both sides to improve your re-assessment performance.
