Muscle Contraction Types

An animated description of isotonic, isometric, and isokinetic muscle contractions.

When you mentioned ISO means equal across tension, length, or energy, that did it for me. Thanks!

Thank you for being the teacher most people don't have in their med schools. May god bless you. Please keep up the good work!

This just might help me pass my CPT exam LOL. It's taken MONTHS for me to differentiate these concepts and this simple monotone video finally put the nail in the coffin. Thank you so much for this informative video!!!

I am so impressed by the explanation and the demonstration .

[gerardoav]

Brilliant! Quite a didactic and easy to follow explanation. Cheers!

[breyonaparker]

Best explanation ive seen thus far!! Thanks!!

[PGayed]

Great video explaining the different types of muscle contractions.

[gwarlow]

Simple principles explained in a simple (easy to understand) manner. Brilliant. Thanks.

[Ehilionomeh]

Great and awesome video;saved me time of studying...it made muscle comtaction so simple...thanks and a big thumb up

[robertslocombe]

Good, clear explanation with examples. Thank you.

[thefitchrist]

AWESOME EXPLANATION! Thanks for making such a great video!

[SukhdipKaur]

Damn thats all I needed to hear than 10 minutes from lecture trying to explain this.

[gillammar]

so precise and easy to understand, bough a book of 240 bucks and that cant expain how wasily you did it.

The tension does not stay the same during a so-called "isotonic" contraction. Both the muscular torque and the resistance torque change as the angles change and so the tension changes as well. Isotonic is a term that we should phase out of our vocabulary.

Clearly explained! Thanks for the video 😊

I’m a senior in hs that understood this perfectly after ur explanations thank u good sir

[nicolesteiner]

thank i get it now. what would i have done before youtube?

The skeleton doing pullups really caught me off guard

Ok, well put together, but i have a question, what is a pliometric contraction then?
I mean i know what it is, but in what group does it fall in? Isotonic, isometric or isokinetic? it's obvious that it's not isokinetic or isometsic, i'm not quite sure if it falls into the isotonic group? or is it just on its own? or is a pliometric contraction a variant of the isometric contraction group? iso- means "equal" but plio- means "more"? I'm done for researching for today, but my assumption is gonna be that the pliometric is a group for itself. i would love some feedback from smart people!

Does gravity play a part in differentiating between isotonic and isokinetic? do dynabands allow for isokinetic movement or would that still be isotonic?
