Test Description: The Side Plank Endurance Test is a reliable tool developed and used to evaluate core, trunk, and hip muscle strength and endurance while minimizing load on the lumbar spine. 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 laying on your side with your elbow positioned under your shoulder and your forearm flat supported on the ground perpendicular to your body. Have your feet stacked, then lift your hips up and off the ground and push them forward. There should be a straight line from your feet to your shoulders. Hold this position as long as you can with good form. Perform on the other side, write down your scores below.
Some rules to remember with this assessment. The test ends if and when (1) your max hip height cannot be sustained, (2) you're sagging through your shoulder, (3) you're excessively rotating your body. Be sure to reference the resource video, "compensations with the side plank endurance test" after performing this assessment on both sides to improve your re-assessment performance.
