Guest guest Posted January 3, 2007 Report Share Posted January 3, 2007 Biomechanics vs PMOT Examination/training of Posture We have been talking about Examination (also how to train) of Human Spinal Posture from a biomechanics vs. PMOT view. PMOT as in human ability to produce force for human movement is increased by basic muscle hypertrophy through Progressive Muscle Overload Training. Biomechanics viewing proper posture and the mechanical advantage it provides as being the key to improvement force for human movement. To narrow down more specifically Spinal posture relative to PMOT or Biomechanics I will begin with the White and Panjabi in their text Clinical Biomechanics of the Spine with their statement the spine's posture demonstrates Biomechanical Adaptation. The spine will adapt a posture relative to effects applied to it. We see the human spine born with a C-shape posture. The same posture that quadrupeds possess. We see that under the influence of the effect of gravity it attempts to grow into the characteristic upright S-shape posture. We see in outer space that without the influencing effect of gravity, the astronaut's spine adapts the simian C-shape. We see it is characteristic as people age they loose the S-shape. They become humped over. The Greeks 4000 riddle of the Spinx asked this question. What walks on four legs in the morning, two legs in the afternoon and 3 legs in the evening and has only one voice? Who could answer it would receive life, who could not would have life taken from them. The answer? Man. As infant walking on all fours, in middle age upright on two legs and as older person walking bent over with the cane acting as the 3rd leg. This is not some idle riddle. When studying human locomotion relative to spinal adaptation it is characteristic to first see the infant with C-spine, then trying to adapt the secondary cervical and lumbar lordotic curves and then in later life seeing the human slump back into the C-shape and will mimic the same locomotion characteristics as the infant. . We see that the Evolution science attributes our unique ability of being an upright bipedal creature is due to our adapting the S-shape from our predecessor the Ape and their C-shape spine. For instance locomotion studies will define one as being either a locomotion (human) machine or a postural maintenance (ape) machine relative to quality of ones postural adaptation and the effect on the hamstring muscle. Proper adaptation of the S-shape posture appears to be the secret behind the ability of humans to leverage upright posture and move against the adverse effect of earth's gravity. It appears that it also gives humans the ability to be upright and work under control against forces that are in front of the body. Such as push a grocery cart hit as in volleyball or push the other fellow backwards in football. So it appears Proper adaptation of the S-shape posture appears to be the key to the human bodies musculoskeletal lever systems effectiveness to jump, run and move forward against the adverse pull of gravity or anterior force. PMOT training does not address adaptation of the S-shape posture as the key to physical ability. It does not try to define what is the model of proper posture or how the posture of the optimal S-shape model, as lever machine, produces superior upright bipedal abilities or produces ability to push against an object to the anterior as in football or pushing a grocery cart. It only addresses muscle hypertrophy on any ones posture (hunchbacked individual for instance) as to running faster, hitting harder. It cannot tell you why hunchback bent over person cannot hit in football or run. Biomechanics addresses what is the optimal model of the S-shaped spinal posture. How as lever machine it produces the superior locomotion as in running. How it produces the optimal leverage for pushing the guy in front of you backwards in football. How it gives the football player the best vertical leaping ability or how it leads to them when standing to stand at the minimal energy expenditure so they are naturally better conditioned. Biomechanical strengthening of the spine is not as PMOT issue, but a biomechanical adaptation issue. Biomechanical or orthopedic strength training that results in the enhancement, restoration and preservation of proper S-shaped posture. So you train the spine properly to adapt the secondary lumbar curves for football for running so your athlete possesses under the skin the optimal posture that produces the best mechanical advantage. It appears to me the world of PMOT training does address the concept of posture affecting performance. It cannot tell you how C-shape spine produces poor locomotion or hitting ability in football because it does not address mechanical advantage. It cannot tell you how to train for adaptation of the S-shaped posture because training for it is only muscle hypertrophy. It does not recognize there exists an effect on earth that relative to gaining a S-shaped posture that your body possesses a better mechanical advantage to function against that effect. It boils down to how does the PMOT mind vs. the Biomechanical mind evaluate spinal posture. I have told you how the biomechanics thinking evaluates spinal posture. Now I would like to hear not only in addition to how I am wrong but a statement how the PMOT thinkers evaluate spinal posture or do they at all? And if they do or do not why? Scherger D.C.
