I. Finally. Understand this! Thank you so much for posting this video. I am studying for my NASM personal training exam and this video has really been helpful.
The brain can use the GTO input to infer information on stretch, in conjunction with other sensory information received (joint position, etc.). It gets complicated quickly!
please explain the connection between the gto and static stretching more indepth. I was under the assuption that static strething lengthened muscles and changed their postural tone, probably via desensitizing the muscle spindle so it didnt contract in reaction to the streching.
In a way, the static stretch does "desensitize" the muscle spindle's effect, by the GTO overriding the muscle spindle input after several seconds. The static stretch also likely pulls the actin and myosin filaments apart a bit, but those will re-shorten if the tone isn't decreased by some other mechanism. And the static stretch likely has some effect on the non-contractile part of the muscle-tendon unit as well; don't forget that the connective tissue that makes up the tendons also runs through the muscle belly. This video is really intended to be an introduction to the two sense organs and their roles. Also, we don't presently understand all the relationships completely, especially once you start considering the role of the central nervous system in all of this. For more information, I'd suggest looking at: Shumway-Cook, A., & Woollacott, M. (2017). Motor control: Translating research into clinical practice (5th ed.). Philadelphia: Lippincott Williams & Wilkins. ISBN 9781496302632
This video was a God Send for me. I'm studying for my CPT and this covered all the info I needed to understand in a really simple layout as it relates to exercise science. Thanks! I finally get it because you made it so simple and straightforward!
Expanding knowledge is always a great adventure that should never be confined to a school setting only. I am happy to see you enjoying the fruits of life.
If for the way to activate GTO need to be apply 6 second long lengthening the component (say the hamstring). During that, how much force should be applied with it? As one of the function of GTO its own, is to sense the huge amount of tension.
That is a great question, Alex, and is beyond the scope of RUclips video comments! To get this answer, you would really have to dig into neuroanatomy and neuroscience at a graduate level. Suffice it to say that there are mechanisms in both the spinal cord and the brain that modulate the excitatory and inhibitory actions of these sensory organs.
Yes, sort of - the athlete is using the stretch reflex to try to increase muscle tone, and increase CNS activation as well to prepare for a quick burst of power. You'll often see sprinters doing plyometrics just before the start of a race.

This was EXACTLY what I needed! My textbook was so confusing x.x Thank you!
Mine too
As someone who is trying to cram all this in his brain for passing a personal trainer exam - this is gold, Jerry! Gold!
Great job at explaining the two - thank you so much!
Very clear video on distinguishing the two!
Your explanation makes it a lot easier. Thank you!
Glad to hear that!
Great explanation! In the end the GTO is also measuring stretch as a surrogate measure of tension

ten-sion in the ten-don! GOLD! thank you so much for making this!
You're welcome - I try for anything that helps!
Dr. Borst
Watching this in 2021 and just want to say thank you! This was very helpful
Glad it helped!
This was such an awesome review. Thank you for creating this video. It really simplified the concept.
Thank you Dr. Borst! NOW I understand this!
THANK YOU SO MUCH! I love your explanation, is so clear!
it's good, totally explain my questions that why both activations of agonist and antagonist could work on stretch
That's great! It is a confusing concept, and one we don't yet understand completely!
OH MY FREAKING GOSH. I didn't notice at first that you are an OT!!!! I have subscribe immediately
I will now binge watch your videos doc! Well after this.. looking forward for more educational videos!
Thanks for subscribing! Please share with your peers and colleagues! Promote OT!
i love you for this. it helped me immensely. know that someone is thinking good things about you today.
Great explanation and concept building. Thankyou sir
Clear and simple. Great job!
this vid was awesome!! totally understand the concept better now! thank you so much
Thank you Dr Borst
amazing clarity
Very nice video....nice explanation...thank u
thankyou sir!! this has been the most understandable video ive watched based on this topic
Very helpful! Thank you for the great video.
Very well explained. Thank you!!
very helpful
This is, like, the awesomest gist of stretch reflexes...✌️
Great explanation, thank you
Thank you! This was so helpful!
Glad it was helpful!
Very informative, thanks
you are genius
What a great video!

Much appreciation! :)
Amazing!
Thanks!
Great info!
Really helpful now I got the point
Glad you found it helpful!
Thank you!
Thanks
perfectly explained. thank u...:)
Thank you!! This video helps.
Perfect, thanks!
thank you!
More tension makes inhibition
😭thank you
This video was a God Send for me. I'm studying for my CPT and this covered all the info I needed to understand in a really simple layout as it relates to exercise science. Thanks! I finally get it because you made it so simple and straightforward!
You're welcome - glad it was helpful to understand the basics!
Dr. Borst
Brilliant video, this really helped me to understand the purpose of both the muscle spindles and the GTO. Thank you.
Spent an hour trying to find a video or article that would explain this until I came across your video. Great job!
Great video perfectly explained
Thank you it really helped me to understand both of them before my official exams.. Clear and simple!
You tha man Doc! Well done
Thankyou sir.
Thank you so much... Very well explained..🙏
You are most welcome!
Goood basic tooo good
Why can’t textbooks just say stuff like this? 😂
Then we wouldn't need the videos! :)
A better explanation than any textbook or article I have read, thank you!
best explanatory video for spindles and Golgi tendon organ!
Thanks Alot!!!
im not even in school or anything but this is interesting to learn why they always say hold the stretch!
Expanding knowledge is always a great adventure that should never be confined to a school setting only. I am happy to see you enjoying the fruits of life.
Great thanks. I now understand why MET PNF and PIR osteopathic stretches are holding for 10 seconds.

As one of the function of GTO its own, is to sense the huge amount of tension.
Thanks 🙏❤️
You're welcome 😊
Thank you so much for helping me understand this very complex topic💕✨
Excellent!
Glad it was helpful!
thanx
You're welcome!
Give this man some upvotes yall! Thanks for explaining my man
how to reduce the effect of the GTO receptors... Do you know any exercises or workout?
Amazing!!! Thank you for this video! I've been confused reading ad this has explained it .. cracking! Grateful
You're very welcome!
Thank you so much, that was some awesome explanation!
Could you explain how the GTO overrides the muscle spindle?
That is a great question, Alex, and is beyond the scope of RUclips video comments! To get this answer, you would really have to dig into neuroanatomy and neuroscience at a graduate level. Suffice it to say that there are mechanisms in both the spinal cord and the brain that modulate the excitatory and inhibitory actions of these sensory organs.
Great video - complicated stuff made really clear and simple.
Thank you! It is very clear !! The best explanation !
wonderful explanation sir
Awesome! Now I get it! Thank you!
thank you so much! finally understood it!
Very insightful! Thank you Dr!
This is great! I read this info in my text six times and still wasn’t 100% clear on it but you explained it perfectly. Thank you!
That has happened to me. Too
This is really helpful! Thank you!
Wow
Thanks a lot! That was loud and clear!
you're a gift from God
Great explanation, thank you!
so helpful
great video. Funny as well
Excellent! Thank u!
Awesome job, thanks.
Perfectly explained 👌🏻👌🏻
this is so well explained - thank you!
Yes, very clear. Thank you.
VERY HELPFUL THANK YOU
Great video!
awesome. thank you
could you clear up the comment you made about if you hold a stretch for a longer time you just lengthened the muscle? Is that a bad thing?
savi3sounds no is not bad . That is the aim of stretching
Is the stretch reflex what is being trained in true plyometric exercises, like the verkhashansky box jump?
Yes, sort of - the athlete is using the stretch reflex to try to increase muscle tone, and increase CNS activation as well to prepare for a quick burst of power. You'll often see sprinters doing plyometrics just before the start of a race.
That was incredibly helpful, thank you for breaking it down!!
Glad it was helpful!
thank you for this, helped a lot
omg thank u so much
Thank you thank you
Nicely explained!!
thanks a lot !!
god bless you
Thank you!
thank you!
