This assessment will be measuring your trunk extensor endurance. You will perform this by laying on your belly on the floor with a small pillow under your lower abdomen. From this position, lift your breastbone or sternum a few inches off the floor and hold. A few coaching tips, protect your neck by keeping your head flexed or chin towards your chest and contract your glute muscles to provide yourself with pelvic stabilization. Once you have lifted your sternum up off the floor start the clock and keep it running until you are no longer able to maintain this position.   Prehab Goals & Normative Values for Sorenson Test: *variation of the above test Males (seconds): 113 Females (seconds) 113   Prehab Goals: >130 seconds for males and females Reference: Biering-Sorenson Test.
