Isometric and isotonic concentric and eccentric exercise

[MrSuperHappyFun]

Best video I've seen on the subject hands down! Thank you!

Great video! Just wondering if I have this correct: When the biceps is concentrically contracting then wouldn't the triceps be eccentrically contracting at the same time and vise versa?

[albertneisser]

@Katrina0839 No. The triceps would be shortening and legthening, but the shortening would not be due concentric contraction, it would be due to the titin(springs) in muscle that partially prevent muscles from being over extended. Look at the exercise around 3:10, she is using her triceps. The only time her biceps would be concentricly contracting would be if she wanted to bring the weight down with more force than what the force of gravity would generate.

@albertneisser Thank You :)

this actually really helped in me study for my phys class... it seems simple enough, but the wording of my prof was confusing. you really clarified it! :)

[carlose198]

Ohhhh okay now I know. Thanks

[TheSUBGAMER]

the important question is,did you fuck her?

[GixxxerKim]

That WAS a big help. I almost thought you'd put the hand in a different position too, it was good you didn't, cause it was MUCH less confusing. Helped me understand more thoroughly.

thanks :)

[yanastekleneva]

[punksk8errrrrrrrrrrr]

[heaterbgrimes]

very helpful!

[KillSwitchOnSteriods]

Very helpful video thank you.

[vinthan99]

well explained video!thank u!

Helpful to understand no joint movement for isometric, Isotonic which is also concentric with shortening and eccentric lengthening.

[everyoneSalegend]

"but don't put your hand around like this, it's just confusing!" ahahahahahahahahahaha funny guy

[sing323]

Its helpful! thx

[psid8]

He didn't explain isotonic

[dukenthaylor]

@psid8 yeah, i got that, too! he also discussed the concept of CONTRACTION, but negated to discuss the contrasting concept of EXPANSION. including both would've completely rounded out this discussion. however incomplete, the individual topics he DID discuss were seemingly done justice.

[Parkjisung91]

@psid8 isotonic comes with the word concentric and eccentric.

e.g 3 types, isometric, isotonic concentric and isotonic eccentric.

Thawt! and break her arm ...hahahaha ... nah just kidding

[citelulah]

thank you!

[sencion809]

It was very helpful to me as well. Thank you!

[amenorrhea]

thank you so much

[boxcuttermarshel]

also good to know if you work out a lot, if you don't resist the weight as you let it fall back down before your next rep then you're missing a vital part of your work out

[ryanfgrant1]

Great explanation! This video was very helpful in demonstrating these concepts for my Anatomy class. Thank you!
