    I was so confused listening to my lecturer. This is the most intelligible video on the topic I found on TH-cam so far.

    Just to be more precise, the tension mentioned here is active tension. Great video!!! Concise & easy to understand.

    This helped me to understand the different point of views of length-tension relationship and force-velocity curve. Thank you so much sir for this simple overview!!!

    Thanks for the video! I think something to point out is that it isn't meant to be a curve if it is related to a single sarcomere; the graph only appears as a curve when taking into account all the sarcomeres of a muscle.

    Kevin!! Clara Goebel here, fellow former SI leader! Just happened to come across this video when trying to reinforce my understanding of this material. I'm in med school now and so happy to have found you again. And thanks for the video!

    That actually really helped me understand while I'm going through my NASM studies. So basically, it's like physics? ... depending on the force applied in correlation to the muscle you're wanting to activate most muscular growth?

  • @jadalaljbour7696
    @jadalaljbour7696 2 ปีที่แล้ว

    great video ,but why in 1(above) of the diagram not equal to (2 )because the overlap between myosin head and actin number didn't change so tension didn't change?

  • @Jean-Mi94
    @Jean-Mi94 3 ปีที่แล้ว +1

    Great explanation but I would have liked probably just an additional information about the contraction phases. Probably just give a visual representation that on the left we have concentric phase and so on :)

    • @alic8094
      @alic8094 ปีที่แล้ว +1

      And right eccentric phase

    I have a question....if the muscle length is decreasing should the tension not increase cuz only when we make the muscles work against a particular load do they start to contract effectively....so why is the tension lower with low length.

    • @CatalystUniversity
      @CatalystUniversity  4 ปีที่แล้ว +3

      This is different that the force-velocity curve, which deals with concentric contractions (shortening) increasing velocity with decreasing load. This is only looking at individual sarcomeres, which function optimally when actin and myosin overlap optimally. Suppose you do a bicep curl. The reason the bicep curl is easiest near the top of the repetition when the muscle is shortest is because the downward torque is reduced with the elbow joint at an angle (a biomechanical effect).

  • @AmitKumar-wv1th
    @AmitKumar-wv1th 3 ปีที่แล้ว

    Sir, what do you mean by optimal resting length ? optimal is clear, why is it called resting length ? if muscle is it resting position or is it in anatomical position. what is resting means here ? can you give an example say bicep brachii or lattisimus dorsi. optimal resting length. thank you..
