Hi, I’m Patrick. I’m a freelance science writer based in the San Francisco Bay Area. I hold a bachelor’s degree in Athletic Training and a master’s in clinical exercise physiology. I used to work in the clinical setting as a certified athletic trainer, physical therapy aide, and a certified strength and conditioning specialist. After working in the clinical setting, I went back to school and became a teacher. The goal of my content is to help normal people, not just pre-med students, learn about the human body. That might mean explaining a topic from an anatomy class or exploring a topic from medical history.

Now, if y'all are wondering where all that ATP powering these contractions comes from--well then boy howdy do I have a video for you: th-cam.com/video/lUrEewYLIQg/w-d-xo.html
Thanks so much for having me on--I'm still BLOWN AWAY that I got to make animations for a Corporis video!
I appreciate if you could explain the following please; when your biceps concentrically contract do your triceps eccentrically contract at the same time? if not what causes the triceps to stretch while biceps contract? @Corporis
Isotonic? More like ginandtonic which is what I’m gonna need after exams
Hey ohh!
your explanation is even better than ChatGPT
this is an achievement
Videos like you guys are the best thing to come out of the internet world. I wish i had this type of learning available when i was at school. Learning via videos work much better than listening to a human trying to keep sane and controlling a class of 40 pupils every day. I'm now 37 and learning things i would never have discovered passion for without videos like these. thanks
I'm in the process of getting my personal trainer certification with an extra few courses on corrective exercises, and your channel has been a total godsend. It's so much more intuitive to understand these principles with the way you explain them, thanks so much for making this content!
Thank you. I am learning this as a hobby to understand my body. You explanation and examples are excellent!
Thank you so much for this. Extremely helpful!
Thank you! Working on an anatomy and physiology essays and this video absolutely clarified the keys differences between the three types of contractions I’m writing on. 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
I can't believe how complicated concentric, isometric and eccentric muscles contraction is! Than we need to pinpoint individual muscles and describe the nature of the motion for the different anatomical movements in the three planes of human movement; I did not foresee that exercise science would be this nuanced! Overall, I'm enjoying this field of study and this is a very nicely made vid, thank you!
The animation of the sarcomere was the best I've come across and really helped me understand what's going on on the microscopic level - THANK YOU!
Thank you! I put together some digital downloads of that image if you'd like them. You don't have to sign up for Patreon to use them: www.patreon.com/posts/sarcomere-for-38536736
Quality video and information. Thank you!
Best video on the topic hands down! Thanks for the help, new subscriber
Very great quality of video and explanation!
Thank you so much for this wonderful piece.
Thank you for this helpful information!
Love the content!
Much appreciated, thank you!
Sir its great…. You push all my knowledge towards application bases….And thats basically the end of all we study …
okay the animations were mind-blowingly awesome, easy to understand. Thanks for these amazing work
You are a great speaker! Thanks so much for this video!
You are so welcome! More coming soon
The quality of these videos is always fantastic :)
Glad you like them! This was a fun one to make
OKAY. Just found out about your channel. You rock good sir. Keep up the great work.
Thank you for making such a great video!
Our pleasure! I've had this one in the idea folder for a long time
Your video is so well explained❤️ Thank you so much, may God bless you
Glad it was helpful!
This channel is extremely criminally underrated!
Much appreciated, thank you!
I would have preferred animation-type of presentation to show visually the Concentreic, Eccentric and Isometric contractions, or ask a person to demonstrate them. Visual always helps. Thanks for your video; this is the first time I bumped into your channel and no doubt I will come back.
Thank you
The collab of the decade. Awesome!
Stoked to get to work with Peter
This is a great video, thank you!
Glad it was helpful!
You are an artist of teaching.
Thanks!
Hey man..do you know any good videos on youtube that explain the class of levers in a easy to understand way?
Helpful 😎👍🏽
Thanks, that makes the difference between concentric and eccentric easy.
(Eccentric: "ek-centric")
As a frustrated massage therapy student who is smack dab in the middle of anatomy and kinesiology classes I thank you
I really enjoy learning from your video. It is really good source of knowledge, but I think you was talking bit to fast and for first couple mins I lost what was you saying. Great work thanks for your help.
wow absolute great way that you explaining thank you way to goo
Glad it was helpful!
nice video!
Thank you! Cheers!
What does it mean when you say "smallest amount of maximal force"?
Great video..
I have 2 question please answer me
1. What is the difference between force production and energy expenditure ?
2. İn the last example (push up) how do you know that the triceps the one who contracte ( concentric,eccentric) not biceps I mean why we don't say the biceps concentric when we go down and eccentric when we go up ?
@Corporis could you please answer the second question - why we don't say the biceps concentric when we go down and biceps eccentric when we go up?
How are isotonic contractions explained with the length-tension curve? I thought that tensions vary depending on the length of the muscle, so wouldn't a true isotonic contraction be impossible?
Commenting to get more content like this!
You're going to love this fall's video then. It's almost entirely musculoskeletal
Thank you. I sometimes get things confused hehe
Hi, I've got some amazing news that will make your day!
Hey, this video was amazing! What do I have to study to learn about this? What is this field called and where can I start?
Physical Therapists, Occupational Therapists, Personal Trainers and Massage Therapists need to know this
Hooray, your Bitcoin transfer is officially in the books!
What about isoconceccentrikinetic?!?!? Riddle me that, science man!
If I had the influence to get your room on Room Rater I would hope they'd give it full marks. Content of video was good too lol
in the first example of isometric, you said force from muscle = from resistance, but if you hold a dumbell in a bicep curl like 12 pounds how is that equal to resistance from the muscle? Is it because from a resistance which is not moving in motion? Also in non- isometric motion if you have a heavy weight why is that your muscle cannot produce the same force?
This is a good question!
The first example is an isometric contraction because your bicep is producing the same amount of force to lift the dumbbell as the dumbbell exerts from its weight. Your bicep *could* produce more force, but at that moment, it's producing exactly as much force as is required to hold the dumbbell in place.
As for your second question, would you mind clarifying? Are you asking why we can't lift very heavy weights?
@@Corporis Yes, I understand much better now...thanks for the reply...Keep up the good work!
I dont get how you can focus on one type, during an exercise isnt it all three if you lift?
Literally learned more from this video than a semester in kinesiology 🤦♂️
That means a lot, thank you. And best of luck in kinesiology
got a thor 4 ad before the video and now imma off myself from the internet forever
SIR! *knocks on computer screen* Excuse me, SIR! *knock on screen even harder* Where were you LAST YEAR when I needed this help and failed my NASM CPT exam! 😛I'mm retesting this year and this FINALLY made sense of the sarcomere and other things!
Can I make animation video with you??
Extremely useful video's available for free :)
Glad it was helpful!
So the gym advisor's "resistance training" burns less energy but produces more force than contracting the muscles would?
Yes! Both on the microscopic filament level AND the macroscopic level. This master's thesis paper from 2016 compared exercise programs consisting of entirely concentric, eccentric, or mixed exercise and found that concentric exercise overwhelming consumed more energy than eccentric. etd.ohiolink.edu/apexprod/rws_etd/send_file/send?accession=kent1479465117642973&disposition=inline
@@Corporis So why is eccentric supposed to be better according to these gym trainers? You'd think using more energy would be a goal
What is “ee-sentric”?? I think he means “ek-sentric”
"superintendent I was just uhh stretching my calves on the windowshil- isometric exercise care to join me?"
YOU SHOULD TRY ANIMATION
Really weird, because if you are pushing a car that is driving towards you. Though that force is greater than your force, your muscles would shorten while pushing it.
OKay so i'm trying to memorize the difference between concentric and eccentric in my head. The best I could do is to say that concentric= contraction. Eccentrice = The opposite
Great in theory, not practical though. Concentric uses far less energy because it takes a fraction of the time as eccentric. Get strong at concentric and isometric, the muscle will accommodate it self as necessary.
The sound when your logo appears sounds like a bad joint crack and it made me queasy during the rest of the video :S
You forgot egocentric. Small unidentifiable movements with enormous weight.
Hahaha, and it somehow extracts everyone else's energy
How many years did you study for making this business? I think youtube is paying you with a bunch of money !
Why do all these fitness people say e-centric? The word is ec-centric. EK-centric.
Speed talking ??!!
Simple way??? Not so sure. Why do people in the states speak at twice the speed in their videos? Great information but not a simple guide as stated.
I think he explained everything in the first 3 minus, after that is just a bonus
Lol wow. We are just a bunch of bio-bots.
thank you i understood nothing
Lord Jesus is the Christ, King of kings and Lord of lords. He is the way, the truth, and the life and no man cometh unto the father but by him alone. He'll give you everything you need, (dwelling) in him there is grace, forgiveness, peace, wisdom, and life; as well as love, strength, and light. God is not mocked! what you sow you will reap. Fear God! repent and believe in him.PRAY ALWAYS!As John 3:18 says
He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
Colossians 3
King James Version
3 If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God.
2 Set your affection on things above, not on things on the earth.
3 For ye are dead, and your life is hid with Christ in God.
Wrong pronunciation for "eccentric". Look up the correct one
Welp. I pronounce it this way.
Facking click bait title, easiest to remember, like common core math were easier, budumtum (onomatopoeia).
Can I help clear up anything from the video for you?
FFS, it's Ex-centric, not E-centric! Basic stuff.
It's a regional thing. I say eccentric, you say eccentric
@@Corporis Not regional, just wrong. Doesn't matter how many of your teachers mispronounced it, it's still wrong. Look it up.
