This video is a solid recap of the different types of muscle contraction! I like how Dr. Goodin mentioned at the end that all of the different types are involved in a lot of movements we do.
So true, this is so natural but I can appreciate movements even more since he put it in more simple terms and connected motions to everyday things and lifts.
Thanks for this good review of the types of muscle contractions! I had never actually considered all the forces that were working in these movements, that was a great reminder to look into the details of what is happening within a movement.
Yeah I agree, having the drawings of where the force is located is very helpful, particularly in understanding the difference between concentric and eccentric.
It's really interesting learning how many forces go into one specific movement, especially when looking at different movements such as bicep curls, push ups, tricep dips and more!
This video was helpful in refreshing my understanding of the different muscle contractions. I found it insightful to note that muscles act as agonists during concentric movements and as antagonists during eccentric ones, while resistive and muscle torque are equal in isometric contractions. Using the bicep curl as an example was a great illustration-thank you!
This one video had more info than all that I’ve learned in my time weightlifting lol. Loved the explanations about the Myelin and actin filaments. They really brought me back to AnP
Thank you for the great review. I appreciate that the video is split between the different parts so that it's easy to go back to a particular section. It will be good to recall and differentiate the types of contraction next time I'm working out other muscle groups!
I agree that was very nice of it to be broken up like that! I'm going to be thinking about my eccentric contractions when I go to failure and can't move the resistive force anymore!
This was a great review of the muscle contractions- I thought it was helpful to include how the sarcomeres and zdiscs play a role in concentric and eccentric movements because those are often overlooked.
This was a great explanation of the three types of muscle contractions. The pictures you drew of each one made it a lot easier to visualize and understand.
The visuals are super helpful, thank you. The repetition of the terms in the video lectures and in class and how much they overlap makes it harder to forget things, which I appreciate.
I totally agree! The repetition really helps to reinforce what we’ve learned, and the visuals make it even clearer. It’s easier to remember when the terms and concepts are repeated in different ways, both in class and through the videos.
Dr. Goodin, what an amazing refresh on the muscle actions of the body. I was reminded that eccentric is not simply just the "downward" motion of a concentric contraction, rather the control movement against gravity as a muscle is eccentrically contracting and controlling the weight. the muscle is actually becoming the antagonist resisting the force of gravity and the tricep extends the arm ( in the case of a bicep curl).
Loved the simplicity of this review, such a good refresher! I loved your point about gravity's role in eccentric contractions and the way you explained what was going on at the sarcomere level!
Such a good video to review the three different types of muscle contractions. It was insightful learning about torque and how it is created throughout each phase. Thank you for using diagrams, it really helps when learning concepts like this.
This was a great recap of the different types of muscle contractions. It is always interesting to learn about the different pieces that go into a movement that looks simple.
This video did a really good job of refreshing my memory on the different types of contractions. I really appreciated the visuals for the eccentric, concentric, and isometric contractions so that I was able to compare it to our physical body.
I have learned about the various muscle contractions before, but this was a great refresher. I also really enjoyed seeing the visuals you included in teh lecture. As a visual learner I always appreciate the use of visual aids along with words and definitions!
Great breakdown of concentric, eccentric, and isometric muscle contractions! The explanation using the example of the bicep curl makes it easy to understand. I appreciate how you clarified the mechanics behind each type of contraction, especially highlighting the role of torque.
I like that you mentioned the bicep being the agonist in the concentric portion of the curl, and the antagonist in the eccentric portion of the curl. This really helped me to put the concepts of biomechanics and muscle contraction together!
The diagram and drawing you created to differential between isometric, concentric, and eccentric contraction was very helpful and gave me a clear understanding for each one!
This video was helpful refreshing the different contractions. I appreciated noting that the muscles are agonists in concentric and antagonists in eccentric, alongside the resistive and muscle torque are equal in isometric. Going through the bicep curl was a lovely example, thank you!
This was a great review of muscle contraction. It was really neat to hear about this and be able to reflect on what I've learned in my time in college. I don't know that I've heard about these concepts as they relate to forces being applied and the resistance of those forces. Very cool!
Great use of the visuals to show the differences in tension and give a breakdown of the sarcomere and z disks actions as well as the myosin and actin cross bridges.
man I didn't know I'd miss your intro so much. I took it for granted lol. you are also a really good drawer! Speaking of that really helped understand better and especially for my notes it helps reminder me of what the notes are for
Thank you for the helpful video! I really liked how you went through the bicep curl and the different contractions. Being able to do it myself alongside the lecture really helped my learning!
Great drawings! During tests, I am always moving my arms around trying to figure out movements (eccentric, concentric, isometric). Great explanation of all of these!
I appreciate you mentioning how the bicep acts as the agonist during the concentric phase of the curl and as the antagonist during the eccentric phase. This really helped me connect the concepts of biomechanics and muscle contraction!
I appreciate your artistic skills! This was a great refresher video and the explanation of resistance and muscle force added a helpful layer to the content!
This was a helpful and concise refresher on the different muscle actions. When looking at isometric contraction I forget that there is more to it than just holding a position and that there are other ways to train isometrically.
since I am in biomechanics right now, this video is very helpful and goes hand-in-hand with the other class. Also a great refresher! Thank you, Dr. Goodin!
I really appreciate this video because it explained all three very clearly. I would always get stuck when seeing these words on an assignment or quiz, and when I would 'research' them, I never got a clear enough answer! I'm glad I can come back to this video!
I was confused about concentric and eccentric contractions and the lengthening and shortening for so long, after first learning it, so its always good to get a refresher.
Muscle contractions can be somewhat confusing to grasp. This video is always helpful when I'm trying to sort out the details. The visuals and your drawings really clarified things for me. Thanks, Dr.Goodin!
This was a great explanation of the 3 types of muscle actions and I appreciated the drawings to help visualize what is happening. I will try practicing them on myself with the bicep curl like you recommended!
Thank you for explaining what contraction is making the muscle the agonist and antagonist! Also great drawings really easy to identify what was happening!
I really liked how we can apply the concentric, eccentric, and isometric positions with the bicep curl! Thank you for drawing the diagrams they were really helpful.
I really liked how easy it was to follow about the differences in eccentric, concentric, and isometric. Eccentric the torque made by the resistant force is greater than that of the muscle force, Concentric the torque made by the muscle is greater than that of the resistant force, isometric has an equal muscle force and resistant force. This is great to remember while lifting and thinking more focused on what the movements are.
This video was a great refresher on different types of contractions. It is important to understand the differences for training designs because each of them plays different roles in muscle control and can affect strength development.
This was a good review of how in a concentric contraction the muscle shortens, in an eccentric contraction the muscle lengthens and isometric in where the muscle doesn't change lengths.
Really enjoyed this video as this is something I constantly think of when I go to the gym and lift. But this video goes deeper into muscle contractions such as considered all factors. Also like the reiteration of saying the muscle never changes size, but rather the overlap of sarcomeres increase or decrease.
This was a great video on the different types of contractions. I think its so cool how sarcomeres work in order to create bodily movement. I'm also quite impressed with your ability to draw on a computer, I find it impossible.
I really like how you explained each one. I knew the main idea between the three but I learned what it meant for the resistive and muscle torques to be different. The arrows did help too!
This was a great review of the muscle actions and this video also helped me understand what is occurring in the sarcomeres during an isometric contraction.
I remember learning about the different types of muscle actions in structural kinesiology and having a difficult time truly understanding. However, like in many other cases, learning about them again helped me feel like I actually really understand this time.
I think this video is perfect when trying to explain to someone what the different types of contractions are for the first time. I thought it was very simple and very well produced.
Thank you for the review Dr. Goodin. All three types of muscle contractions are very important for gaining muscle. I like to focus on eccentric after a bicep curl because i can feel the muscle tension the most.
I found this to be good review of the 3 different types of muscle contractions and I liked how you explained what is happening when we are "flexing" our muscles
I really enjoyed learning about the different types of muscle contraction. I find myself saying these terms during my workouts a lot to ensure I am doing the right movement
Before watching this video, I'd always been curious about during an isometric contraction, what do the sarcomeres actually do? But the explanation of switching from sarcomere to sarcomere makes a lot of sense.
Aww missed the sick intro on this video but it was a nice surprise seeing it as an outro instead! Miss that ocean view. Thanks for drawing out the different kinds of contractions. Your little drawings were well done and really helped get the point across visually. I am still confused about torque but hopefully I'll get the hang of it!
The muscle contraction is one of the most fascinating things to me! Z discs are still difficult to understand but this video helped me a bit in visualizing the "flex" of our arms! Ive also noticed how much more my muscles, specifically in my arms have been reacting and growing to eccentric movements paired with isometric holds!
This was a great and simple video about muscle contractions! From previous anatomy and kinese courses, these three types of muscle contractions have been engrained into my head; however, I liked how you touched on the resistive and muscular forces because those seem to not be talked about as much.
A great reminder of the three muscle contractions and I love how simple you made it with the example of the elbow. And I love how you encourage us to practice this on ourselves since you can learn these muscle contractions with muscle memory. (see what I did there.)
Great video! I love learning about these muscle actions because I can immediately think of examples when I am working out and how my muscle feels while doing the exercise. At least for me, the biceps are a great example that never fails when I forget the movements during a test!
Dr. Goodin thank you for these explanations on muscle contractions. During eccentric contraction I forgot that the force of gravity played a role in the muscle lengthening.
This video was great to review the different types of muscle contractions! Even after taking multiple classes using these terms, it's always nice to come back to basics :) the drawings of the joints are helpful in visualizing!
Great explanation of the different movements using a biceps curl. It can be hard to conceptualize these things using scholarly terms, but your explanations really help!
These illustrations were very simple yet effective at demonstrating the different types of muscle contractions. Even though these types of movements are a bit more simple to understand than others, these types of contractions are very vital in understanding when it comes to training (weight lifting).
Sir could i just clarify as i am having a debate with a UK exam board - for a Bicep curl on the way down - the agonist is the tricep, and the bicep would be the antagonist, or is the Bicep the agonist (even though it is lengthening)for the downward phase of a bicep curl.
This video is a solid recap of the different types of muscle contraction! I like how Dr. Goodin mentioned at the end that all of the different types are involved in a lot of movements we do.
For sure! It is cool to think that we use all these movements everyday, not just during exercise!
I agree!
Agreed! They all work together to allow us to function!
So true, this is so natural but I can appreciate movements even more since he put it in more simple terms and connected motions to everyday things and lifts.
Thanks for this good review of the types of muscle contractions! I had never actually considered all the forces that were working in these movements, that was a great reminder to look into the details of what is happening within a movement.
I agree! It is crazy to think about all the things going on in the body to make a movement happen.
Yeah I agree, having the drawings of where the force is located is very helpful, particularly in understanding the difference between concentric and eccentric.
I agree I had never heard of contractions explained in that way either!
It's really interesting learning how many forces go into one specific movement, especially when looking at different movements such as bicep curls, push ups, tricep dips and more!
Yes I totally agree! So much is happening during these movements and it's nice to have a breakdown explanation of all the components at play.
This video was helpful in refreshing my understanding of the different muscle contractions. I found it insightful to note that muscles act as agonists during concentric movements and as antagonists during eccentric ones, while resistive and muscle torque are equal in isometric contractions. Using the bicep curl as an example was a great illustration-thank you!
Yes I totally agree with you!
This one video had more info than all that I’ve learned in my time weightlifting lol. Loved the explanations about the Myelin and actin filaments. They really brought me back to AnP
I agree! Definitely a good refresher that ties in a lot of what we have learned in the past!
I agree even though the video was short and concise- it explained all the most important elements to know about muscle contraction!
Providing their practical implications really puts the 3 different muscle actions into perspective.
I agree, taking complicated topics and providing practical implications always makes it easier to understand.
Thank you for the great review. I appreciate that the video is split between the different parts so that it's easy to go back to a particular section. It will be good to recall and differentiate the types of contraction next time I'm working out other muscle groups!
I agree that was very nice of it to be broken up like that! I'm going to be thinking about my eccentric contractions when I go to failure and can't move the resistive force anymore!
Also agree with this. It’s very easy for when I go back to study some of the topics I’m less confident in
Dr. Goodin did mention to practice all three in a movement to get a good feel for them!
Agreed
I really enjoyed how he put the topic into application so it is easier to follow and now I can think of this during my lifts as well!
This was a great review of the muscle contractions- I thought it was helpful to include how the sarcomeres and zdiscs play a role in concentric and eccentric movements because those are often overlooked.
Definitely agree the micro level is overlooked!
This was a great explanation of the three types of muscle contractions. The pictures you drew of each one made it a lot easier to visualize and understand.
The visuals are super helpful, thank you. The repetition of the terms in the video lectures and in class and how much they overlap makes it harder to forget things, which I appreciate.

Gravity should always be taken into account for sure😂
This is true! It is easy to forget about the little details.
I really appreciate how this video went over all three of these really clearly and made it easier to understand.
I agree!
i agree
Loved the simplicity of this review, such a good refresher! I loved your point about gravity's role in eccentric contractions and the way you explained what was going on at the sarcomere level!
I completely agree! A short video but it covers each concept in detail with a good explanation of what happens at each step.
Agreed
Going over the main muscle contractions was super helpful for me. Your diagram drawings are definitely better than anything that I could have made.
The diagrams were awesome haha
Such a good video to review the three different types of muscle contractions. It was insightful learning about torque and how it is created throughout each phase. Thank you for using diagrams, it really helps when learning concepts like this.

These were great illustrations of muscle contraction! I appreciate the explanation about there being equal torque in isometric contraction.
I really appreciate the illustrations you drew when explaining eccentric vs concentric contractions. They were very helpful!
This was such a great refresher! The visuals are super helpful as well as the explanations. Going back to the basics is always great!

I agree Dr. Goodin is quite artistic
This was a helpful and concise refresher on the different muscle actions. When looking at isometric contraction I forget that there is more to it than just holding a position and that there are other ways to train isometrically.
Getting a refresher on muscle contractions is very helpful and builds a base for what is to come for future lessons.
This was a great review of muscle contraction, and the visuals were also super helpful to compare concentric, eccentric, and isometric.
I love being able to continuously use this video as a refresher on the types of muscle contractions.
since I am in biomechanics right now, this video is very helpful and goes hand-in-hand with the other class. Also a great refresher! Thank you, Dr. Goodin!
This is such a great visual to understand muscle actions, especially that concentric and eccentric contractions are the opposite!
I really appreciate this video because it explained all three very clearly. I would always get stuck when seeing these words on an assignment or quiz, and when I would 'research' them, I never got a clear enough answer! I'm glad I can come back to this video!
Really great explanation of the 3 types of muscle contractions. I liked how you added in what's happening at the sarcomeres for each movement!

Gotta build the base before refining it
This was a good review of how in a concentric contraction the muscle shortens, in an eccentric contraction the muscle lengthens and isometric in where the muscle doesn't change lengths.
This was a great summary of concentric, isometric, and eccentric muscles. It was so helpful!
Really enjoyed this video as this is something I constantly think of when I go to the gym and lift. But this video goes deeper into muscle contractions such as considered all factors. Also like the reiteration of saying the muscle never changes size, but rather the overlap of sarcomeres increase or decrease.
I agree! the description of movement of the sarcomeres gives you a better visualization to what is happening
This was a great refresher on the different muscle contractions that occur! Thank you
This was a great video on the different types of contractions. I think its so cool how sarcomeres work in order to create bodily movement. I'm also quite impressed with your ability to draw on a computer, I find it impossible.
I really looked for this thorough explanation, thanks! now i finally understand the concept of different contractions.

The drawings were really beneficial in helping me understand the different movements in each type of contraction.
I loved learning about the different muscle contractions as I sometimes get confused about which. Thanks!
Loved the deep dive on the 3 different types of contractions!
This is was a good review! The pictures helped me understand the different types of contractions!
I recall learning these muscle actions in other classes, but this was a great refresher on the material.
This video was a great recap in going through the explanation of concentric, eccentric & isometric muscle contraction!
Great recap of concentric, eccentric, and isometric contractions. I also liked how you included sarcomeres and their role in muscle contractions

Thank you for clarifying the three different contractions and how the different forces impact each one.
Honestly a great refresher video for the terms as it has been a whole summer where I didn't use any of these terms at all.

Ive also noticed how much more my muscles, specifically in my arms have been reacting and growing to eccentric movements paired with isometric holds!
This was a good review of the different muscle contractions. I appreciate the drawings!
Awesome explanation for the "bro science" way of thinking how muscles work. Very helpful!
This is definitely something we've gone over in many of our other KIN classes although a welcome refresher

Thanks for the recap Dr. Goodin, always appreciate the examples you provide!
Being able to do these movements on myself is very helpful and makes more sense. It's so interesting to know how muscles act.
Dr. Goodin thank you for these explanations on muscle contractions. During eccentric contraction I forgot that the force of gravity played a role in the muscle lengthening.
Although I have already learned much of this information, this video was good review on concentric, eccentric, and isometric contractions.

This was a great review from what I learned in anatomy and also biomechanics!
helpful and detailed review of different contraction types and their characteristics
Great refresher of each movement!
Sir could i just clarify as i am having a debate with a UK exam board - for a Bicep curl on the way down - the agonist is the tricep, and the bicep would be the antagonist, or is the Bicep the agonist (even though it is lengthening)for the downward phase of a bicep curl.
That's correct Eugene. Because the biceps is slowing the rate of extension, it is considered an antagonist. Good luck in your debate!
Always found it hard to explain what an eccentric contraction was but this video gave a good simplified definition.
This was a good review of Biomechanics during my junior year! specifically the lengthening and shortening of the muscles.
