Today\u2019s episode features biomechanist and inventor 大卫·韦克. \u00a0No stranger to new ideas and insight in human locomotion and athletic movement, this episode breaks a few molds that the human body has been put into over the years. David\u2019s original appearance 上 episode 107 made significant waves, as David spoke 上 why bracing against a transverse force doesn\u2019t happen in athletic movement, and how training this way in the weightroom is not conducive to proper motor patterns. Now, David gets to a topic that is 上 the forefront of his system, which is the role of the pulsing and spiraling action of the arms (and the human body as a whole) in being as fast as possible. \u00a0Our current paradigms of movements (and coaching them) often rely 上 looking at endpoints, without regards for what happens \u201cin between\u201d, and the resultant timing and mechanisms that power those positions. \u00a0Or, many times experts look at the world\u2019s fastest competitors, and list what they are doing right as \u201cwrong\u201d. As a community, we also tend to frown 上 frontal and transverse plane movement in things such as straight-line running, while this coiling movement is actually essential to success. Sub topics include the \u201cpulse\u201d action of the arms in running, principles of utilizing the fascial system in locomotion, pressurization in movement, as well as how to use asymmetry rather than destroy it. \u00a0\u00a0This podcast is huge for anyone who wants a deeper look at how the body actually operates while sprinting, and common traits of the fastest athletes 上 earth in this regard in both team sports and track & field.\u00a0 Today\u2019s episode is brought to you by SimpliFaster, supplier of high-end athletic development tools, such as the Freelap timing system, kBox, Sprint 1080, and more.\u00a0\u00a0 Key Points: \tHow the arms impact the \u201cjolt\u201d action of running, and the importance of the \u201cdouble down pulse\u201d technique \tThe impact of the fascial system 上 the connectedness of the human body, speed and running technique \tImportance of pressurization in the \u201cjolt and pulse\u201d system of locomotion \tImplications of pronation and supination in muscle length and shortening, and body rotation \tAsymmetry in the body and locomotion, as well as how to take advantage of that asymmetry Quotes: \u201c(Speaking of prehistoric man) Carrying a long stick of functional capacity, you cannot swing the arms\u201d \u201cIt\u2019s the cascade of frontal plane first (in running) that turns the spinal engine 上 \u201d \u201cThe instant before maximum ground loading, the hands stop their downward movement, not by a muscular effort, but by a fascial, connective tissue effort\u201d \u201cJog across the room and pay attention to what your hands want to do\u201d \u201c(In regards to the jolt or pulse of the arms) We are dealing in microseconds, but the body is naturally geared to find it\u2026 this is happening faster than the speed of thought.. it is a sensation you are going to feel\u201d \u201cYou can\u2019t run with a neutral pelvis and expect to be fast at all\u201d \u201cIt\u2019s an alternating\u2026 lordotic, kyphotic, then it switches. \u00a0And the fastest people have a big lordotic\u201d \u201cIf you apply the mechanical force to the fascia, then you don\u2019t even need to send the signal to the spinal cord, to send back to the fascia\u2026. so it\u2019s faster than the electrical current that goes through your body\u201d \u201cIf you are born with the big muscles, it\u2019s very different than if you had to pump up to build the muscles (from a fascia perspective)\u201d \u201cYou want to think of the muscles as a pressure system\u2026 you are a pneumatic system\u201d \u201cLook at the animals\u2026 it\u2019s just a pulse of force and they\u2019re gone\u201d \u201c(In running) It\u2019s underhand figure 8\u2019s with the shoulders, overhand with the hips\u201d \u201cSupination is the \u201cshort\u201d and pronation is the \u201clong\u201d\u201d \u201cJust the very act of supinating your right hand will coil your right lat to some extent\u201d \u201cAsymmetry is the rule\u2026 not the exception but the rule\u201d \u201cYou don\u2019t push out of the blocks, you pulse out of the blocks\u201d \u201cEveryone is going to have their own unique specificity that is going to make them faster\u201d Show Notes Asymmetrical \u201cwind and whip\u201d sprint PR (3% speed improvement) View this post 上 Instagram的 A post shared by Joel Smith (@justflysports) 上 Aug 12, 2018 at 3:36pm PDT About 大卫·韦克 大卫·韦克 is the creator of\u00a0WeckMethod\u00a0and the CEO and Founder of BOSU Fitness.
