  • Find out why the length of a sarcomere (in diastole) affects the amount of force that it can generate (in systole), and how that would look on a graph. Rishi is a pediatric infectious disease physician and works at Khan Academy. Created by Rishi Desai.

    I've been struggling with this topic in the past few months . I never fully understood this sentence " overlapping of actin = less force of contraction= less tension ) . But now,everyting is so clear ! I made all the drowings that u made. ty so much

    now after this video it all makes sense
    thank you as hell

    Is this the basic principle as to why we get tired holding a rock in the same place even though no work is actually done? The sarcomere gets stretched and this leads to space for contraction, utilising ATP, and keeping the rock in place, at the expense of more ATP. Is this right?

    So, just to clarify, the greatest amount of tension is generally created at the midpoint of the shortening and lengthening curve? So halfway up during a bicep curl (or halfway down)?
    Bonus- tension can and should be consciously generated (by squeezing and contracting a muscle) throughout the entire contractile range in order for muscular hypertrophy? Correct?

      @jennifero5263 3 ปีที่แล้ว

      So in summary what he’s saying is tension increases as sarcomere length decreases right?

    you neglect the passive force though. the passive force is even higher than the active force in picture number 5. not realistic but in theory it's the highest amount of force that can be generated
