New Squat Law Fails In Court

Hey Matt and Ben,An answer to Ben\'s qusteion would be supposition given the evidence at hand but I think we can arrive at an educated guess. Nachemson\'s work back in the 70 s is often quoted for demonstrating large compressive forces in the lumbar discs in sitting in a variety of postures. Janda pointed out the relationship between habitual sitting and development of muscle imbalances about the hip, the so-called lower cross syndrome. Shortening of the hip fexors and inhibition of the glutes was the hallmark of that condition. When a person with that motor pattern squats, they exhibit an inability to open the hips, press the knees out and spare the spinal lordosis under a load. McGill has shown us a clear path in which regular loss of the lumbar lordosis under a load causes disc injury.So, my best guess would be that since lifting a load from the ground is a common activity in both aboriginal and civilized cultures, the more flexible hips of the squatters would allow them to perform that task while maintaining the lordotic lumbar curve.We have to collectively wince at such supposition as these are tenuous connections without clear causality. Although I\'d be fair game in an Aristotelian logic class with my remarks, I think they are appropriate for our discussion.What bugs me is the amount of lumbar spinal flexion I noted in the youTube video that Matt linked a few weeks ago. I was surprised to see the rounding of the spine in that posture of the aboriginal folks. It would be interesting to see what the condition of their spines were.
