Very good video, thank you! Also, to demonstrate the isometric contraction, you can hold an empty cup and then pour coffee into it- heavier load, muscle works more, but it's length doesn't change.
Happy Birthday to you!. And Today is October 2nd, 2022, my birthday. And yes I have to spend part of the day studying for the Anatomy and Physiology test tomorrow. So Cheers!😁
Thank you. The daily life examples help me a lot as I am a visual learner . Will look forward to your in-depth video about cellular level of these movements:)
@@aphysionamedjonah rehabilitation, assignment 2 for late stage ankle rehab i needed the part for eccentric, concentric, isometric.. Thanks i just wrote down what you said for the last part of it..
Hahaha, Jonah I've been following along with your videos and am loving them so far. Your personality shines through and the addition of "wii music" is a nice touch. Glad to see you're up to something productive with your quarantine. Looking forward to the next one and Happy birthday!
Thanks a lot Garrett! Glad you picked out that very distinct Wii Sports intro music haha, I'd argue it's one of the best compositions of the 21st century. Really appreciate the birthday wishes and feedback :) it means a lot!
Can you do a video on dysfunction/injury in movement that can cause hypertonicity, spasm and involuntary contractions or when ligaments become hard like bones? Also old spinal injuries that can cause problems as you age, such as damage to the coccyx, fractured verterbrates, just constant overloading of the body due to things beyond someone's control? Also problems caused by dna. Thankyou.
Wow thanks Jeet! I really appreciate that :) The fact that I've already been to reach as many people as I have with videos like this one is crazy to me! I'll definitely be continuing this channel since I'm really enjoying the process of putting these videos together, and my goal is to keep making better and better content as I keep learning and growing!
Well done bud. I'm an old timer(46) who took way too long to get into shape. I spend lots of time in the gym and hear the words all the time. I just wanted a basic explanation, and you provided bgg it perfectly. PS...I'm a full-blown technology resister and this is my first online comment ever. That should serve as proof as to my satisfaction with your vid
Wow Patrick, that honestly makes my day to hear that! So glad you enjoyed and it was helpful with clarifying some of that confusing terminology the exercise world can be full of. Keep going strong on that work in the gym!
What about the anti gravity concept. Like pull-ups. Doesn’t concentric contraction involve moving against a force such as resistance or gravity ? And how would it apply to a simple elbow extension and flexion. Thanks
Good question! Concentric contraction definitely involves moving against a force such as resistance or gravity. So, in the case of a pull up, the concentric contraction would be moving against the force of gravity because body weight is the resistance in this case. Muscles like the lats, biceps, and trapezius would be active concentrically during the pull up phase, then concentrically on the way down (picture the bicep flexing on the way up to the bar, concentric, and lengthening on the way down, eccentric). Same concept with a regular elbow extension/flexion! As the elbow bends the biceps contract concentrically, and when the elbow straightens the biceps contract eccentrically. Hope this is helpful!
Glad you're enjoying the videos, and great question! A lot of exercises will involve concentric and eccentric phases of glute med activation, but I'll pick out a couple here with some video links that emphasize one more than others. Banded crab walks are a great one to focus on the eccentric phase as the band providing tension emphasizes the eccentric slowing when you bring your feet together. Of course this exercise also includes concentric when stepping apart, but it's a great one for eccentric emphasis! th-cam.com/video/7C8mL0v976o/w-d-xo.html Concentrically, performing hip abductions against gravity is a nice straight forward one. Your concentric phase will be lowering the leg back down, but working concentrically against gravity is a nice one to visualize. th-cam.com/video/-rDiQXjeXO0/w-d-xo.html Isometrically, contracting your glute med will placing pressure into the wall standing on one leg is a way to isolate. The glute med is very active while standing on one leg and using the stance leg to create pressure into the wall emphasizes this. th-cam.com/video/ny5WDD_1XsE/w-d-xo.html Good luck with your glute med training :)
I'm glad videos like this one have been able to help you! If there are other topics you'd like me to touch on let me know, I'll do my best to incorporate them moving forwards :) Good luck with your program!
Best explanation ever 🙏🏻 So concentric type of contraction is the only one that recruits most or all of muscle fibers? And the difference between biceps eccentric and triceps extension is the harmony of movement, But what is the difference between muscle relaxation and eccentric contraction, is it the tone ?
Thanks Zeinab! Concentric contraction doesn't necessarily mean that most or all of the muscle fibres are contracted, it just refers to the type of contraction (aka the shortening). Exactly, eccentric contraction vs relaxation refers to muscle tone. So a relaxed muscle would be not contracting in any meaningful way. An eccentric contraction could be happening as a muscle is "relaxing" aka bringing your arm to your side, but the muscle is actively contracting as it is lengthening.
Hi Sophie! You're very welcome, glad it was helpful! For a book more on general health and holistic thinking I really liked "The Ripple Effect" by Greg Wells. A bit more of a specific book for PTs would be Kelly Starrett's supple leopard, but it's a bit of a longer more textbook style read. Happy reading!
Hi thanks for your video and is it the same way to explain the situation of climbing stairs? When we go upstairs that is concentric movement and when we go downstairs isometric movement involved. So it needs more muscle control when we go downstairs?
Good thinking! Upstairs is more concentric muscle contraction, whereas downstairs has more eccentric muscle contraction (less so isometric) that causes the deman on muscle control to be higher!
Not a type I'm super familiar with! My quick research seems that it's a specific type of machine that operates to maintain the speed (root word kinetic in there) constant throughout motion. Not a super common one or something I've come across in my professional life, so good question!
Hey! All of them are going to involve multiple phases but emphasize different things. For the primary muscle groups, deadlifts would represent primarily concentric muscle activation, as the main action is lifting or shortening. Leg extensions are similar, but have an eccentric phase as you bend the legs again.
Hip thrusts would also be primarily concentric as the main action is concentric contraction of the glutes as the press happens! Once again, there is an eccentric phase though as you return to the starting position.
Thank you so much for this!!! 🙏✨💞Loved the way you explained it & the examples you gave! Also it’s November & all late but happy late birthday, thank you for making this on your birthday haha 😂 🎂✨✨✨💃🏽💃🏽
A 23 old man is physiotherapist!! 😳 In my country its not possible to be a graduate at this age. l am almost 22 but I am just in 2nd year. BTW, you did the great job. Hopefully you'll do the same thing in future.
Well thank you! I will definitely keep doing my best to make better and better videos. I'm 26 years old now, and I've been practicing for a couple years now. I graduated young as I went straight from high school into my undergraduate degree, then got accepted right into physio school the year I was done my undergraduate. So 4 years undergrad plus 2 years of a Masters, 23-24 is really young for a Physio here in Canada too! Good luck with your schooling :) it's worth it when you're finished!
Its nice to know all this but theres no point. The important thing is that your doing physical activity and enjoying the exercises that you do. Unless youre trying to be a champion body builder knowing your eccentric vs concentric muscle growth is just overcomplicating the process of muscle growth. Studies have shown that there is only a 2-3 percent increase in muscle growth for those that are favoring eccentric growth. The most important thing is that you are in the gym and youre putting in the work. Do the exercises that you like and diversify your exercises to work out different muscle groups
You aren't wrong at all for the average individual really diving deep into different types of muscle training isn't necessary for their training. My hope with this video is more that it can help people understand the different types of contraction for their own knowledge or academic pursuits, with its role in targeted training being more understanding vs. prescriptive. Diversifying exercises is always a great option!
We are a quick chatting excitable bunch aren't we! In all seriousness, this is something I think I've gotten better at as my TH-cam channel has progressed along. It's really easy to let your pace get away from you when you're talking on camera, but reigning that in has definitely been a focus as I've been doing this more. Hope the video was still helpful!
Very good video, thank you! Also, to demonstrate the isometric contraction, you can hold an empty cup and then pour coffee into it- heavier load, muscle works more, but it's length doesn't change.
