Symptoms Can Include:
Anything from dull ache to extreme pain in the lower region of the back.
Relationship to Body Structure and Behavior:
The erector spinae (ES) muscles are posture-muscles and eccentrically contract.
Co-contractions of other postural muscles including the psoas muscles are very important to distribute force while extending the hip joint.
For ES and PS to act together as a lever to extend the hip joint, proper tension of the body is very important at the end of stance phase.
This becomes critical for jumping/hopping/sprinting.
Suggestions for Prevention:
For the eccentric contraction, stretch of ES by upper body weight upon each stepping is important. Gravity enables the stretch when we look down during casual walking. Eye fixations on the ground targets during casual walking is just two steps ahead. Looking down for the gaze will induce the eccentric contraction of ES naturally. Arm swing will stabilize the lower back by counter rotation to the swing leg.
