    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

    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 in understanding the key concepts like rate of force development and emphasizing how their role enhances athletic performance and improves speed and agility. Great video!

    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 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.

    Enjoyed learning about the differences between stride length and stride frequency and how they tie in together

  • @thomaskinzler
    @thomaskinzler Місяць тому

    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.

    Comparing the stretch-shorting cycle to a spring made it a lot easier to comprehend!

    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 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 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.

    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!

    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!

  • @macynunez4455
    @macynunez4455 9 місяців тому

    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.

    it's interesting how stride length can help with speed but also how it plateaus at a certain point

  • @cjbuenviaje
    @cjbuenviaje Рік тому

    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)

    Looking at the graphs, the difference in the acceleration phase compared to the maximal velocity phase is interesting.

  • @brysonhashimoto2878
    @brysonhashimoto2878 Рік тому

    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.

    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.
