Being German, I at times have a hard time properly understanding specific paragraphs.
Does the following indicate that the butt-wink is not a big deal? Thank you!
"Anyway... just the other day, I came across this interesting paragraph in Functional Anatomy of the Spine by Middleditch and Oliver:
"Tension in the thoracolumbar fascia can also be increased by motion of the arms, legs and trunk. Posterior rotation of the pelvis causes an increase in flexion at he lumbosacral junction and hence increases tension in the thoracolumbar fascia. Lumbar spine flexion also passively increases tension in the thoracolumbar fascia. Competitive weightlifters may flex or 'round out' the lumbosacral area and it is suggested that this affords some protection by increasing tension in the thoracolumbar fascia and posterior ligamentous structures, thereby contributing to stability in the low lumbar area (Dolan et al, 1994).""
