FHP. In my humble opinion - you are one of the best sources of delivering complex concepts in accessible, clear, jargon free terminology. Thank you.

[psjfree]

thanks man ! watching you from the middle east, Jordan university , can't comment on this video ! Islam taught me to salute who teaches me ! big thanks !

[MirthfulSpiritofHeavyRealm]

Excellent video, perfectly cleared this up! Thank you!

[Angieraquell]

WOOOOW I literally had the "ah-ha!" moment...thank you so much!!!

Thank u!!! Iv hade a terible time understanding the eccentrick phase with force velocity you uave helped so much

[mosesbygate-smith]

I assume you mean it's lower force production during dynamic concentric movement compared to the force production capabilities during eccentric muscle actions? All portions of the force velocity curve are all technically still high force when considering GRF during sprinting and unresisted jumping. Just trying to wrap my head around all of this, your explanation clarified a few things for me!

[zoddnosferatu]

Thx even though i watch this to add reference for my physiology learning about muscle

[cmmiguelx]

2:34 you cant press it back up cause you'd have to put more strengh than weight of the bar, if you put less strengh the force of gravity will push it against you, it doesnt mean you're producing more power.

If tha bar is static youre producing the same amount of force as the object, if youre lifting youre producing more and if its going down youre producing less. This has nothing to do with velocity/type of contraction

[louisreilly]

great video, thankyou. But what about isometric contraction?

[Tom-nyyc]

Its confusing because it ignores the factor of gravity. It is not a controlled experiment. How can they say this is purely the mechanics of the muscle fibres when they have not taken away gravity?

[JamesCanDoIt]

How does the relationship relate to explosive pull-ups?
What is the best way to train to improve the explosiveness of the pull-up?

Because there is a decceleration at the eccentric part.

And load is hard to make less because its your bodyweight.
Thanks.

What about after 90 degrees? Is it not the same eccentric after 90 because the muscle is maximally lengthened?

[hendyounis]

If asked about the tension inside the muscle, , do I use the same relation supposing force here to be same as tension in the muscle ???

[youtubecomenter]

How is velocity measured? By the rep speed/time taken to complete a rep?

[athletic_doc]

Dont you produce more force on a sprint or a max jump than on a max squat? This curve makes intuitive sense, but I feel like force plate data contradicts this with the actual values. Is it really referring more towards mechanical tension vs velocity instead of force vs velocity?
