    Breathing is an under-appreciated aspect to movement. Breathing is done 20,000+ times daily, it is literally the most important thing we do. There are only 2 ways to breathe:
    Diaphragmatically, or with Secondary Musculature (SM) AKA Mouth/Neck breathing.
    When breathing Diaphragmatically, the entire axial skeleton will expand 360 degrees with each inhale/exhale, this includes the rib cage, pelvis and cranium. This is what allows range of motion to exist. If your anterior chest is compressed and not expanding due to “tight” pecs, your shoulder IR will be limited. If your posterior rib cage is compressed and not expanding due to “tight” back musculature, your shoulder ER will be limited. If the posterior pelvis is compressed and not expanding, your hinge will be limited, which can give the impression of tight hamstrings.
    With SM breathing, this 360 degree expansion is impossible due to the tight muscles, such as spinal erectors, lats and pecs being used to breathe. This limits range of motion throughout the entire body and this is the root cause to many issues. The only way to down regulate SM breathing is to line your bony structures properly and breathe diaphragmatically.
    I reached out to you before on your previous video about fascia and still no response (Ive been checking my spam). Id still love to collaborate with you to bring this “Pressure Centric Mental Model” to life. It’s a topic that is starting to gain attention however most current examples are low fidelity which makes the concept difficult to understand. I believe your talent can make this powerful concept simple to understand and deliver high valuable content

      @ thank you! I have. It was from doing so called split squat pulses way too fast. It did not cause any pain in the moment but later in the session doing a different move I had instant noticeable tightness on one side. Def my body trying to protect me from a pretty bad exercise execution. My body eventually let go of it after consistent much slower moves for that area over several weeks. Really important to listen to the body!

    Could you explain the phenomenon of paresthesia? How does it occur and how to get rid of it or alleviate the symptoms? Thank you.

    How do you make these animations? Is there a programmatic way to generate these? I'm looking for an anatomically correct model for my current research.

    • @AnatomyLab
      @AnatomyLab  11 днів тому

      I use a 3d software called blender.. but it’s not what you are looking for..from my understanding there is no automatic system to do this..

    Great Video. My problem is that my hamstrings/calves (biceps femoris) are always tight. My knee seems to be frozen. I do train legs an stretch. Any video on frozen knees? I will try your method. maybe I am doing it all too haphazardly.

    • @AnatomyLab

      it seems you are really tight- just check back with a pt- so you really know what you’re dealing with…

    I think I experienced the stretch reflex while doing uncontrolled movements during the light bike crashes that often happen to me. I tried hard to save my 120kg bike from falling down and felt sharp pain in my back, some tension and willingness to stretch my back. It's like something is pinched in the back. This pain remained for a few weeks while doing rotations. I had anti inflammatory and massage therapy to make it go away.

      thanks for sharing! that could be a reflex or maybe a strain.. anyway keep riding hard!!!

    I usually think of the stretch reflex in the context of jumping -- you don't settle into a squat and pause before jumping up, you drop down to preload your muscles.

    • @AnatomyLab
      @AnatomyLab  11 днів тому

      You’re absolutely right! The stretch reflex plays a key role in activities like jumping, where the quick stretch of muscles and tendons helps preload them for an explosive movement. Dropping into a squat before jumping is a great example of how the body utilizes this reflex and stored elastic energy to maximize power. Thanks for bringing up such a clear and practical application!

    I wonder about how hyper-elasticity affects this reflex.

    • @AnatomyLab
      @AnatomyLab  5 днів тому

      that’s a good one! I’m not really sure.. I think it will just be triggered Later-Because people that are hyper elastic, just reach that and end Range of motion very late, so there’s no need to trigger…but I would have to do Some research on it if there is any… Anyway, have a good day And thanks for posting this input
