I like how you pointed out that a person can over stride in certain situations while running. "Lengthen your stride!" was a very common thing yelled on tracks when I was in h.s.
It was interesting to learn how force affects stride length and overall frequency. I have had coaches who talk about this stuff but never realized how much of an impact these variable have on performance!
I found this video particularly fascinating as it introduced new scientific models related to sprinting that I wasn't familiar with before. For instance, it covered the spring-mass model and how an individual’s muscle configuration can influence their spring mechanics during sprints, ultimately impacting their overall speed.
This video was super helpful after reading through the material in the textbook. The book definitely covers a lot of material so it was nice to hear your explanations of topics, charts, and graphs discussed in the book.
I think its cool learning about stuff we've learned about in other classes in this class...in this video it was biomechanics. It is cool to be able to connect what you learn in different classes to each other.
I really enjoyed how clear each section of how speed and agility can be measured and broken down. It is important to note the differences and biomechanical focuses and needs between a track sprinter and a soccer player in terms of support and directions of force.
I found it extremely interesting how stride length and frequency interact to be a function of velocity. I figured that stride length would plateau at some point because realistically a person's legs are only a certain length, but had never thought about how the frequency of strides increases to increase velocity. I figured it was just a result of power output, so to understand how stride frequency is at play is very helpful.
I really enjoyed your explanation of the neurophysiological section because after reading the section there was some parts that I was confused on that this helped me to understand.
The spring mass model was such a helpful analogy! Also stride length and stride frequency was so fascinating.. and definetly got me thinking on runner height!
Great breakdown of the workings of the SSC i particularly liked the spring mass model as that has always helped me to visualize the muscles actions through various movements.
I found this lecture and topic to be very interesting and appreciated the spring-mass model and how muscles participate in spring-like actions when sprinting or moving at high speeds. The graph provided explained this model very clearly!
Love learning about how the SSC is so important in sport, looking past how much and athlete can squat or bench has certainly helped me create a better understanding of athletic performance.
I like how we used concepts from the previous chapter about the SCC and applied it to the topics talked about within this chapter. It helped me get another perspective on the SCC and how important this concept is.
I like how you pointed out that emphasizing these exercises can increase the neural drive while overloading the musculature of the hip and knee regions that are involved in the SCC.
This video was super interesting to me as it introduced new models behind the science of sprinting that I had not previously heard of. For example the spring-mass model and how a person's muscle configuration may affect their spring mechanisms while sprinting, thus affecting their overall speed.
Your videos are so important for me as I am planning to apply CSCS next yr after my graduation. M learning a lot by watching your videos. Thank you so much
So cool to think about how the science behind the SSC and proper stride length and stride frequency impact speed and have the power to achieve proper biomechanics. I'm interested to learn about how to individualize this since we are all different heights and have unique anatomical measurements.
As much as I hated my Physics courses, I know now why it is so important in Kinesiology. I'm glad that some of the things I learned can be applied to these topics of speed and agility.
I didn't realize how much of a factor stride length was initially and then stride frequency causes that next increase once the stride length plateaus. Thank you!
This channel is super valuable, thank you so much! I plan to apply for ETSU's sports performance PhD program this year, and I hope I can get in and help others just like you did!
I found the spring analogy for the Spring Mass Model very helpful in understanding the graphs and reading related to neurophysiological changes that can occur with speed training! Also thought learning more about how much your stride can impact the speed you go was very interesting!
That is cool how you get to read a chapter by your thesis mentor. And I never knew that much technique and biomechanics can go into sprinting since it only last for a few seconds.
It was interesting to see the relationship between an athlete's speed length as well as speed rate/frequency and I think the graphs really helped me understand the relationship and how this can change between trained and untrained individuals.
Not only the ability of an athlete's acceleration is important but braking forces as well as many injured themselves with poor agility and mechanics during change-of-direction
I found the stride length and stride-frequency graph really interesting and makes sense as to why athletes with longer legs run faster than athletes with shorter legs because they cover a lot more ground each stride. But it also looks easy for some sprinters because they are not really on the ground for a lot of time (i.e. Usain Bolt running a 9.58 second 100 m sprint without having a great start, but the strides carried him in front of everyone else after 50 m)
Something interesting this chapter pointed out was that power isn't really something that can be measured and that there are other measurable variables s&c professionals should use
I think the information about rate of force development is very important because athletes need to develop a lot of force in a very short amount of time. Training should reflect this by movements that will produce a lot of force in short periods of time such as olympic lifts.
Hello Dr Goodin, I recently got an project from my exercise science class to make a "program design for resistance training" which videos should I watch and what other resources would you advice. I'd really appreciate if you could help me. Thank you for uploading videos for exercise science everyone in my class uses your videos to prepare for tests and exams.
Hi sir. I m preparing for CSCS exam. Is it necessary to read and understand every single detail given in the text book for the exam?? or understand the topics you discussed in the videos are enough for the exam and i should focus more on these?? If you please guide me in this , it will be really helpful for me. Thank you 🙂
I like how you pointed out that a person can over stride in certain situations while running. "Lengthen your stride!" was a very common thing yelled on tracks when I was in h.s.
Super interesting breakdown on speed and agility! Never knew how much RFD plays a role in how quickly an athlete can accelerate and change direction
Enjoyed learning about the differences between stride length and stride frequency and how they tie in together
It was interesting to learn how force affects stride length and overall frequency. I have had coaches who talk about this stuff but never realized how much of an impact these variable have on performance!

The best refresher video I’ve seen since I was certified 12 years ago as an nsca cpt. Thank you Dr Goodin! Great video. Got me pumped!
Comparing the stretch-shorting cycle to a spring made it a lot easier to comprehend!
I appreciate the use of graphs - they definitely helped with understanding the material :)
This video was super helpful after reading through the material in the textbook. The book definitely covers a lot of material so it was nice to hear your explanations of topics, charts, and graphs discussed in the book.

Every time the SSC is mentioned I’m always amazed
Thank you for breaking down every phase that happens during a change in direction. The drawings helped!
The explanations alongside the graphs were super helpful!
The analogy of the muscles acting like a spring coiling and uncoiling is helpful!
I really enjoyed your explanation of the neurophysiological section because after reading the section there was some parts that I was confused on that this helped me to understand.
It was interesting to learn about this difference between impulse and rate of force development and what they show us about an athlete!
what seems to be so complex, you make seem so understandable and comprehensible!
The spring mass model was such a helpful analogy! Also stride length and stride frequency was so fascinating.. and definetly got me thinking on runner height!
Great breakdown of the workings of the SSC i particularly liked the spring mass model as that has always helped me to visualize the muscles actions through various movements.
it's nice to have a breakdown of measuring speed abilities because it empowers you with how to improve it.
There is so much that goes into becoming faster. Thanks for explaining!
The explanation of the graph helped me grasp the concept of the spring-mass model and how it is used in biomechanics
This video helped me understand that stride length as well as stride frequency are important in terms of speed.
thank you for including and explaining the graphs!

It is so important to have a strong trunk! Along with this, making sure to work on stride frequency/length.
I like how you pointed out that emphasizing these exercises can increase the neural drive while overloading the musculature of the hip and knee regions that are involved in the SCC.
This video was super interesting to me as it introduced new models behind the science of sprinting that I had not previously heard of. For example the spring-mass model and how a person's muscle configuration may affect their spring mechanisms while sprinting, thus affecting their overall speed.
The stretch-shortening cycle was really interesting to go over again here in the video as I didn’t fully understand the cycle beforehand
I liked your analogy of muscle being like a spring and how it coils and uncoils as a person is running.
Finally able to put my physics class to something I enjoy!
Your videos are so important for me as I am planning to apply CSCS next yr after my graduation. M learning a lot by watching your videos. Thank you so much
So cool to think about how the science behind the SSC and proper stride length and stride frequency impact speed and have the power to achieve proper biomechanics. I'm interested to learn about how to individualize this since we are all different heights and have unique anatomical measurements.
Very interesting to see how important both stride length and frequency are. I have definitely seen both ends of the spectrum.
This saved me. I have my exam coming up later today so thank you!
how’d it go??
I liked the slide where you broke down what is happening in the change of direction and how center of gravity comes into play
Thank You Sir. I am pursuing Msc. Sports Science .Your Playlists are so valuable to me
As much as I hated my Physics courses, I know now why it is so important in Kinesiology. I'm glad that some of the things I learned can be applied to these topics of speed and agility.
I found the visual of the spring-mass model helpful with how it shows the graph and the spring during each phase.
the srping mass model was super cool to me. It shows how intricate our bodys and muscles are made, to wear our muscles can act like springs
I didn't realize how much of a factor stride length was initially and then stride frequency causes that next increase once the stride length plateaus. Thank you!
It was interesting to learn about the RFD and how it can influence movement techniques with force along with impulse!
This channel is super valuable, thank you so much! I plan to apply for ETSU's sports performance PhD program this year, and I hope I can get in and help others just like you did!
Thank you Hanwen. Best of luck as you apply!

I really appreciated this video explaining the textbook in a more direct manner. The text was a bit more intimidating.
I really thought it was interesting to hear about RFD and how it affects speed an agility
It was interesting learning about the stretch shortening cycle. It is something I have always heard about, but I never actually knew what it was.
It was interesting to learn that RFD and proper biomechanics are the two main factors influencing sprint performance
I learned that along with having a strong core, it's important to have a strong trunk to reorientate the body when running in new directions.
it's interesting how stride length can help with speed but also how it plateaus at a certain point
An interesting concept that I found in this lecture is that a strong trunk can help with lateral movement when changing direction.
I thought it was a cool idea to think of running phases and muscle movements as a spring!
Looking at the graphs, the difference in the acceleration phase compared to the maximal velocity phase is interesting.
Not only the ability of an athlete's acceleration is important but braking forces as well as many injured themselves with poor agility and mechanics during change-of-direction
I found the stride length and stride-frequency graph really interesting and makes sense as to why athletes with longer legs run faster than athletes with shorter legs because they cover a lot more ground each stride.

Something interesting this chapter pointed out was that power isn't really something that can be measured and that there are other measurable variables s&c professionals should use
Running in slow motion is a great way to describe a person who is over striding when running!
I think the information about rate of force development is very important because athletes need to develop a lot of force in a very short amount of time. Training should reflect this by movements that will produce a lot of force in short periods of time such as olympic lifts.

Chapter 17 and 21. So far I have done videos on chapter 17. Chapter 21 will come later this summer
For some reason I never considered that the trunk would help with lateral movement
Hi sir.
I m preparing for CSCS exam. Is it necessary to read and understand every single detail given in the text book for the exam?? or understand the topics you discussed in the videos are enough for the exam and i should focus more on these??
If you please guide me in this , it will be really helpful for me.
Thank you 🙂
I thought the graphs for RFD were interesting because we want to to be vertical rather than exponential with a fast, high velocity movement.
I ddin't realize how many different speed and agility are from each other.
