You're amazing! Easy and to the point explanation. This is the first time I understand this topic because of the simple examples. Usually professors don't use examples which makes it hard to grasp the concept.

[@Ematuresco]

@@ProfRoofs dear Prof. Roos, I have a question which I'm researching forever. When you put your arm high up at 90° degrees ("spider curl") to generate active insufficency of the long head of the biceps in order to shift some focus on the short head of the biceps brachii - isn't this defeated by a concept called "reciprocal innervation", meaning that the long head of the triceps stretches in the position and sends a "relax" signal to the biceps brachii - so the body is confused whether to contract(due to mechanical tension during a curl and active insufficency) or relax the biceps ("reciprocal innveration"), thus we feel a cramping at the highest contraction position, but it's not what we sought out to do. In other words, does this exercise (90° spider curl) achieve what it is designated for ?

[@eishajoshi2183]

Finally understood the length tension relationship after like 4 years of my life as a bachelor. I had a doubt, if a person is more flexible that is their muscle length is more then the recoil would be more hence tension will be more, so why do you say it's less in the end??

[@Cojomo]

Hmm very interesting...

[@marouaranialeghlimi8822]

tu m'as sauvé la vie

[@texastexas4541]

Nice video. Question 1: What skeletal muscle length did you change at 13 min? Without specificity, it is impossible to understand how that angle change produced more force. Also, my professor told me that most skeletal muscles are always acting at optimal sarcomere lengths because they are attached to the bone. Question 2: Can you tell me which skeletal muscle operates below optimal length (resting length before contraction is initiated) and Question 3: which skeletal muscle operates beyond optimal length. I am not finding answers to these 3 questions anywhere. Your help (or someone else reading this) would be much appreciated.

[@sambergold]

[@ProfRoofs]

[@tomhanratty6056]

Really great video. It helped a lot. I have a question tho. Would it be right to take from this that the reason muscle force output is lower at a faster speed of muscle contractions is due to the muscle spending less time in a state where all 16 of the myosin arms are in contact with the actin border? Where the amount of ATP consumed doesn't change according to the shortened state of the muscle, but the amount of functional movement decreases?

[@ThuyNguyen-iu8df]

[@AliRaza-ro8ev]

Hey excellent video just a little hiccup when you explain the active tension curve you show it kinda bell shaped curve , but when you combine passive and active curve together you show an overshoot of purple curve upwards showing maximum tension , but should not it touch baseline? As you increase the length , actin myosin overlapping decreasing and tension being rapidly decrease...which ofc u explained...i just can't understand that overshoot of purple curve in the end

[@kshamtaagrawal6352]

U nailed it 😍

[@faizanwani_]

This is best ❤

[@ProfRoofs]

Faizan Wani thank you!

[@texastexas4541]

I have a question. Sk muscle operates around resting length most of the time. Your last part of the video suggests otherwise. It is possible that you are able to lift more weight (angled bench) because you are now recruiting other muscles but not increasing the muscle length of biceps.
