What are Plyometrics? | CSCS Chapter 18

[@miadenava585]

I appreciate how you discussed the mechanisms and principles of plyometric exercises and highlighted their role in enhancing athletic performance. This video was super helpful.

[@cameransherwood5157]

The idea of our muscles acting like rubber bands that build up energy when we stretch and contract the muscles quickly really helped me understand plyometrics and the benefits of Plyometric training

[@DevanneyBoyd]

I appreciate the in-depth breakdown of the stretch-shortening cycle, a critical component of plyometrics.

[@Moniiiqueee824]

The explanation of the shortening cycle, along with the idea of muscles as rubber bands that build up energy when stretched, really made the video’s content clear. Thanks, Dr. Goodin!

[@NoelleDarquea]

Your visual explanation using the long jump example was great. It’s clear how launching from the right angle can help increase distance

[@karatemplin]

I like how this class continues to touch on the same topics as exercise physiology. This helps explain the same concepts in different ways, helping further my learning and understanding.

[@mollytucker567]

The visuals when breaking down the stretch-shortening cycle was actually very helpful in this video!

[@ellieconiaris9073]

This was a super helpful video plyometrics are something that I did not have a deep understanding of until this video!

[@willhopkins4197]

As someone who did pole vault in high school, great to know my sport can be a good example of a strength and conditioning concept!

[@ClaireStone-jq4wg]

You helped me understand how the stretch-shortening cycle is both more efficient and more forceful.

[@aliciahernandez00233]

This video was very helpful in understanding plyometrics. The explanation of the way our muscles act during these movements was really helpful.

[@MatthewDuPrey325]

The way that you broke down the three plyometric phases was really useful to me when learning all of this.

[@abartsch0022]

I like how you summed it up in an easy to understand video and how the book's idea of a long jump is wrong. But that is cool how this whole thing has to be fast otherwise it doesn't matter all that much and is lost as heat.

[@TRamos-pl6oo]

its really cool to me how the neuromuscular system works. not only are there conscious muscular movement in the SSC, but there are subconscious movements going on that we dont even control

[@wyattcarlson7504]

The explanation of the mechanical model helped me to more fully understand the skeletal muscle function during certain movements. Some of these movements are included in plyometrics.

[@ryanharris8481]

The explanation of the phases of the stretch-shortening cycle helped me understand why it is important when it comes to plyometric training

[@dereklinck2672]

The breakdown of the different phases and visuals really helped me to understand the concept and importance of plyometric exercise in an athlete's arsenal.

[@jakegonzales1367]

I never really understood the whole concept of plyometrics and the difference between the physiology and the mechanics behind it. After watching this video I can confidently say that I now know the basics of Plyometrics.

[@macynunez4455]

So cool to see how the stretch-shortening cycle plays a huge role in ploymetrics and the physiological process of how that is executed in our muscles.

[@Adam.gates_]

Potentiating a muscle before a plyometric movement is a great idea for readily firing those type IIx fibers. Thank you for sharing that!

[@emilywalker5871]

Potentiation is so fascinating. If I I’m understanding it correctly I think we did this when we were learning the snatch in class by shrugging the shoulders and then performing the exercise.

[@ameliabrock]

The example of a long jump was something I didn’t expect to see, and it was very interesting to learn about “pole vaulting” with the front leg. Thanks for explaining things clearly as usual :)

[@kieranmccarty4050]

I appreciated the way you explained the stretch shortening cycle and the table used. This has been talked about in many classes but this was easiest to understand.

[@madelinejewelnebril2871]

This video help me become familiar with plyometric training since I had little knowledge on what it entailed.

[@thomaskinzler]

The stretch reflex and SSC has been fascinating to me ever since we performed the knee jerk test in my A&P lab, so to understand how it is certainly at play in plyometrics is very interesting.

[@everoche3754]

I was never aware that plyometrics would have greatly influenced my jumping and power capabilities in my high school soccer career. I also had never heard of the amortization phase before, so it helped build my understanding about the stretch shortening cycle greatly.

[@zoiezantua7002]

Thank you for explaining the stretch shortening cycle, it's all very new to me but you broke it down well!

[@joyshang5670]

I was a bit confused about the mechnical model but seeing the visual representation helped me better understand it! Thanks!

[@alannabergherm8046]

The example of the long jump was really helpful in understanding the 3 phases of the stretch-shortening cycle (even with the incorrect foot placement for take-off)!!

[@moirabryson5042]

Thank you for breaking down the plyometric phases in such a nice way! Really helped me understand it better

[@dimitricarrion6145]

Hi Dr. Goodin! I liked how you broke down the stretch reflex step by step

[@AylethLizarraga]

The break down of the stretch -shortening cycle was very helpful!!

[@torilucht5871]

I really appreciated this video and found it to be a great overview explaining the stretch-shortening cycle. The example of the long jump was a good way to see how this works in real life.

[@morganrolleri9198]

I enjoyed learning about what plyometrics are and what the different phases of the stretch-shortening cycle are.

[@lexireynish5892]

This video was so helpful in further understanding the stretch shortening cycle!

[@BrianaReynoso]

The video really helped break down the stretch-shortening cycle in a manner that was easily absorbable

[@kelli-lynroche8446]

This helped me understand the importance of training the stretch shortening cycle in plyometrics.

[@evaozimec]

I enjoyed your example explaining the stretch-shortening cycle.

[@julianasum8481]

This video helped me understand the three phases of plyometric movement, eccentric, amortization, and concentric.

[@wyntonbrown9439]

Really enjoyed learning about the mechanics of plyometrics

[@hannahb872]

I liked the visual explanation you gave with the long jump example. It makes sense how you'd gain more distance by your launching point being at a certain angle! Excited to learn more about plyometric exercises!

[@chynnakifer1218]

It was very interesting learning the neurophysiological properties of the stretch reflex! Thank you!

[@audreyoates3242]

It was very interesting learning about the different phases of the stretch-shortening cycle. There is so much more to plyometrics than I thought!

[@lucamarin8565]

great explanation of the stretch-shortening cycle, very interesting

[@matthewwadley4348]

Great introduction for plyometics for someone who knows very little about knowledge of the concept itself

[@avajgallo]

Very interesting!! I never learned about this in detail and it is all coming together.

[@madelinehernandez8838]

It is interesting to learn about the muscle spindles and the stretch reflex. This is going to be sent to the spinal cord via Type Ia nerve fibers. I also loved the example of the long jump!

[@celinegriffin3244]

I really liked the stretch-shortening cycle and learning about the three phases. Never had heard about amorization, though the figure wasn't a well explained picture of all three phases you did explain it really well.

[@tianguyen3897]

I was very intrigued by the stretch-shortening cycle. Table 18.1 was very helpful in my learning of the three phases (eccentric, amortization, and concentric)!

[@bensonmutuvi8429]

It’s awesome to learn about plyometrics as I have barely any knowledge on it.

[@laurenwahl9715]

It is interesting to think about the stretch shortening cycle in relation to energy build-up, and how these relate in a bigger way to plyometric training.

[@jakegellatlyperformance]

I think it’s really cool to see how athletes who are elite in utilizing the stretch shortening cycle are able to be extremely strong and explosive without actually carrying that much contractile muscle tissue

[@devynpryor8228]

I'd heard of eccentric and concentric contractions, but never learned about the amortization phase before.

[@rozalynnlarson8835]

The term amortization phase is new to me. It was interesting to learn about how the length of this phase typically indicates an athlete level of strength

[@xmysteriousx3548]

awesome lecture once again

[@DrJacobGoodin]

Thanks again! I appreciate the feedback.

[@thelmasepulveda4481]

It was interesting to learn about the stretch-shortening cycle and the three phases of this. It is a bit confusing since it's a new concept but the table really helped me understand it.

[@MrSriphat07]

Thank you Professor, this is very helpful.

[@DrJacobGoodin]

You are very welcome

[@braedenmoore3743]

I had never heard of the amortization phase but it was interesting to me how when comparing athletes of the same bodyweight, the stronger athlete will have a shorter amortization phase.

[@melanieweirich8482]

I've heard plyometrics mentioned in the gym space in the past but never really understood what it meant. It's a bit confusing still but I think along with the next few videos I'll be able to understand it a bit more.

[@sarahcox-barden]

I thought the stretch shortening cycle was interesting! Seeing how it relates to our testing for sports was a helpful application

[@clairemasterson6031]

I never knew the "pause" had an actual name or was considered a phase itself until this chapter!

[@chayanvats4366]

What would be the effect of a longer eccentric phase on the energy stored via series elastic components?

[@kylesands9693]

Does series elastic component or parallel elastic component contribute more to force production?

[@brysonhashimoto2878]

It was very interesting how if 2 people with the same body mass were to perform a vertical jump. The one who can squat more in comparison to their body mass will probably jump higher because they are able to utilize the stretch shortening cycle better.

[@nandisaputra3282]

Hallo, Dr Jacob. I have confussion about terminology desciption. Can you explain to me about simple analogy of kinetic and mechanic difference? Thank you Sir ...

[@caleighgarcia7792]

I did not know that the amortization phase was a thing. I think it makes sense that if someone is weaker or is working at higher intensities, why this phase would be longer.

[@joshcombs123]

I like trying to connect concepts from plyometric training into the plyometric aspects of baseball

[@khalidalbadr1329]

Thank you again Dr.jacob it is very informative lecture. I have a remark on the amortization phase , the figure shows the whole sole of the foot on the ground,while in the explanation state that this phase must be kept short..landing on the sole delay the time. In depth jumps the touch is very minimal. How can we combine these matters ? Regards ..

[@alextruban5818]

Hey Professor. I have been watching your videos in preparation for the CSCS and they have been very helpful. Is there a way to download the powerpoint slides you use to use as a study tool?

[@DrJacobGoodin]

Thanks Alex! So glad they've been helpful to you. Unfortunately I can't make the slides available because they are modified from the publisher for teaching use, but you are welcome to screenshot them.

[@charmenatchison854]

I now understand why my amortization phase is so slow since my surgeries. And I know what to doabout it.

[@VirAquinoPLNU]

im curious with what it actually looks like with the first contact since the image wasn't correct

[@jupshaw]

The SSC could be considered one of the most important factors in sport when looking at RFD and how "twitchy" an athlete can be.
