Show Notes:

Special guest today, Professor Carlos Lemos Jr, a 4th degree black belt Brazilian Jiu Jitsu professor at Gracie Barra Downers Grove.

Join us for a great 90 minute podcast with my good friend, mentor, teacher and all around great man.

We talk about many interesting things, including movement, learning, history and so much more. IF you thought you new all about jiu jitsu, you are in for a lesson or two today. This certainly opens up things for Part 2 in the near future.

Sending a V16, with tears of joy. More neurology of movement: Climbing impossible stuff.

This badass just did a V16 here in this video, translation, the Mount Everest of bouldering. He deserved to cry.

Spin this picture 180 and he is crawling, finding points of “fixation”. What is neat about climbing is that you can have one, two, three or four points of fixation, unlike walking (one or two points) and crawling (two, three or four points of fixation). The difference in climbing is that gravity is a bear, wearing you down, little by little. A deep similarity in climbing to any variety of crawling is that both involve pulling and pushing, compressing and extending over fixation points. Other common principles are those of fixation, stability, mobility and neurologic crawling patterns in order to progress.
Some research has determined that in quadrupeds the lower limbs displayed reduced orientation yet increased ranges of kinematic coordination in alternative patterns such as diagonal and lateral coordination.  

This was clearly different to the typical kinematics that are employed in upright bipedal locomotion. Furthermore, in skilled mountain climbers, these lateral and diagonal patterns are clearly more developed than in study controls largely due to repeated challenges and subsequent adaptive changes to these lateral and diagonal patterns.  What this seems to suggest is that there is a different demand and tax on the CPG’s (central pattern generators) and cord mediated neuromechanics moving from bipedal to quadrupedal locomotion. There seemed to be both advantages and disadvantages to both locomotion styles. Moving towards a more upright bipedal style of locomotion shows an increase in the lower spine (sacral motor pool) activity because of the increased and different demands on the musculature however at the potential cost to losing some of the skills and advantages of the lateral and diagonal quadrupedal skills. Naturally, different CPG reorganization is necessary moving towards bipedalism because of these different weight bearing demands on the lower limbs but also due to the change from weight bearing upper limbs to more mobile upper limbs free to not only optimize the speed of bipedalism but also to enable the function of carrying objects during locomotion. 

This brief excerpt was taken from one of the many articles I have written on the complex biomechanics and neurology of climbing and movement. Search for it all on our blog, thegatiguys.com
