    Hi, I’m Patrick. I’m a freelance science writer based in the San Francisco Bay Area. I hold a bachelor’s degree in Athletic Training and a master’s in clinical exercise physiology. I used to work in the clinical setting as a certified athletic trainer, physical therapy aide, and a certified strength and conditioning specialist. After working in the clinical setting, I went back to school and became a teacher. The goal of my content is to help normal people, not just pre-med students, learn about the human body. That might mean explaining a topic from an anatomy class or exploring a topic from medical history.

    Now, if y'all are wondering where all that ATP powering these contractions comes from--well then boy howdy do I have a video for you: czcams.com/video/lUrEewYLIQg/video.html

Learning via videos work much better than listening to a human trying to keep sane and controlling a class of 40 pupils every day. I'm now 37 and learning things i would never have discovered passion for without videos like these. thanks

    I can't believe how complicated concentric, isometric and eccentric muscles contraction is! Than we need to pinpoint individual muscles and describe the nature of the motion for the different anatomical movements in the three planes of human movement; I did not foresee that exercise science would be this nuanced! Overall, I'm enjoying this field of study and this is a very nicely made vid, thank you!

  • @sherjeelrmalik
    @sherjeelrmalik Před 3 lety +1

    in the first example of isometric, you said force from muscle = from resistance, but if you hold a dumbell in a bicep curl like 12 pounds how is that equal to resistance from the muscle? Is it because from a resistance which is not moving in motion? Also in non- isometric motion if you have a heavy weight why is that your muscle cannot produce the same force?

    • @Corporis
      @Corporis  Před 3 lety +1

      This is a good question!
      The first example is an isometric contraction because your bicep is producing the same amount of force to lift the dumbbell as the dumbbell exerts from its weight. Your bicep *could* produce more force, but at that moment, it's producing exactly as much force as is required to hold the dumbbell in place.
      As for your second question, would you mind clarifying? Are you asking why we can't lift very heavy weights?

      Yes! Both on the microscopic filament level AND the macroscopic level.

    Great in theory, not practical though. Concentric uses far less energy because it takes a fraction of the time as eccentric. Get strong at concentric and isometric, the muscle will accommodate it self as necessary.
