The Most Powerful Muscles in Walking: Glutes vs Psoas-How to Walk Properly

The most powerful muscles in walking: Glutes vs Psoas. In this video I discuss the difference between how we use the glutes when we walk and how we use the psoas. I will focus in on the hip extensor portions of the glutes and compare them with the hip flexor psoas muscle. Both muscles are important in gait, but at different times and in different situations. It is important to understand how to use these muscles, because improper use can lead to a variety of different health conditions. On level ground, we are not using glute extension significantly. The glutes fire eccentrically during loading response to decelerate the flexion of the forward hip that occurs after heel contact. EMG studies show the glute max stops firing after the forefoot hits the flat position. This means the glutes are not powering the swing through portion of gait. The swing through is powered by the psoas muscle, in conjunction with the other core muscles and muscles in the legs. The glutes become significantly more active when we begin walking up a slope, even a small one. In this circumstance, the glutes are required on the rear leg to push the body forward during loading response. After the forward foot hits the flat position, we switch to psoas flexion. This pulls the lumbar spine forward, triggering the rise of the body to a standing position on one leg. This movement is aided my the knee extensors and ankle dorsiflexors. The movement pattern here is identical to the movement used during the swing through on level ground. Because of the slope, the movement results only in a standing position, not a full swing through. The glutes must then be reengaged to complete the swing through.

It can also result in an anterior pelvic tilt and exaggerated arch in the lower back. Improper use of the psoas muscle can result in duck foot walking and posterior tilt of the pelvis.

The core muscles have largely been ignored in research on walking technique. Visit my website: https://www.movementsphere.com/todd-m... This video is part of The Walking Code by Todd Martin MD.
