Being able to understand the differences between strength and power is valuable, especially if you are working with athletes in a specific field, with specific goals in mind. Seeing the difference in the videos shown was insightful.
Hi Zara! I agree with you, being able to differentiate between power and strength is valuable, especially when you are applying ti when working with athletes.
I agree with your insight! Especially working with athletes with specific goals, it is important to differentiate strength, power, acceleration, and work.
I agree that understanding the differences between the two is important. I appreciate how the professor explained the difference between the two. It helped me understand each of those terms better.
This was a super interesting video to watch. Usually understanding the difference between power and work is confusing, but having the definitions explained side by side was very helpful. Also the visuals are incredible, those guys spent years doing what they do and are experts in the sport.
Knowing the difference between strength and power was is super helpful especially when working with athletes who are trying to improve their overall performance.
This video was incredibly helpful in distinguishing between power and strength. For me, the height of the athlete performing the squat really helped clarify the concept of work. The videos provided great clarification and practical examples of strength versus power. Thank you!
I really appreciated your emphasis on distinguishing strength from power. I think it is so important that we use these terms appropriately and your examples definitely helped to demonstrate a clear vision of the differences!
I didn't know there was so many technical terms associated with biomechanics, but looking back at it, it totally makes sense due to how many vectors are being applied in the field. I appreciate the video as I have now a bigger understanding of the terminology!
Hey Siros! You are absolutely right! It's fascinating how the breakdown of technical terms can turn complex movements into measurable components that are much easier to understand. For me, gaining a deeper understanding of the terminology helps me understand how biomechanics is truly a mixture of science and athletic performance.
I thought that the examples given in the video were great! It applied these biomechanics and physics topics of work, power, and acceleration to real life examples that apply to our future professions.
The examples were super helpful! It helps me learn concepts better when presented with examples that I can think of applying to real life. It helps me remember the material better!
I appreciate how the three biomechanical concepts (strength, power, and work) were explained as influences for athletic performance and training designs. Knowing the differences of each concept allows training programs to be tailored to specific goals.
Thanks for explaining strength, power, and work in depth. It helped me to be able to see and hear these definitions. I think Rihanna must be a biomechanist, because I remember a few years ago she was excited to teach everyone about "work, work, work, work, work, work!"
This video helped me understand how different powerlifting and weightlifting are. I always saw people moving a lot of weight and assumed it was the same thing but I now realize they are performed completely differently and require very different training. I wonder how much a soccer player should focus on weightlifting or powerlifting to help with performance on the field. I assume that a soccer player should focus on weightlifting because soccer is an explosive sport but I would like to see some research on how much either of them help!
You bring up a good point. I was also thinking about how different sports and athletes should train differently based on their specific demands the sport requires. There are a lot of different factors that play into that decision I assume, an interesting discussion for sure!
This is a super interesting point. I played soccer for a long time and oftentimes only had weight training implemented in my training routine if it was in PT.
I totally get what you're saying about powerlifting and weightlifting being different. For us since we play soccer, weightlifting makes sense because it helps with quick, powerful movements. But powerlifting can also build strength that might help with things like sprinting and jumping. It would be cool to look into research to see which one is actually better for soccer players or how much of a balance with each will create the most beneficial outcome.
I found your question fascinating about when is the right time to use weightlifting or powerlifting- I would have to agree that soccer players most likely should focus on weightlifting rather than powerlifting because of the explosive demand.
Discussing the biomechanical definitions of strength and power provides a better understanding when describing an athlete as "strong," where time is essential to consider. The videos of the athletes were a valuable addition to understanding strength and power.
I like how you touched on the idea of work and provided the example of a taller athlete in comparison to a shorter one and how their anthropometrics affect the biomechanical leverages of the movement paths!
I really enjoyed the strength and conditioning section of this lecture with showing that strength and power both reflect the ability to exert force at a given velocity. I had been under the impression that strength was always slower and power was fast!
The distinguishing between strength and power is awesome. I see so many people in the industry that I have been trained by and trained with that use both strength and power incorrectly. This is a good explanation of the difference that can be directly translated down to the athlete in a way that will help them understand it as well, which is the main goal. Plus, using the work concept to chip your buddies for failing deadlift reps has a fun aspect to it.
I enjoy this video because it allows me to achieve a deeper understanding of biomechanical definitions of strength and power. It clarifies the difference which can be easily mixed up.
Learning that height plays a part in how much that individual may work when performing a back squat was intriguing. I appreciate the example of comparing a 7-foot individual to a 5-foot individual. It really helped me grasp the concept better.
I love this video!! It gave me a much clearer understanding of how strength, power, and work are all interconnected and yet still have their own concepts in biomechanics. I was also intrigued by discussing rotational work and torque. Breaking them down like this makes me see how they apply to explosive movements and highlights how physics governs performance at every level!
Being able to watch the videos and these insane examples of strength and power made this video more fun to watch. I think seeing such exaggerated examples helps show the clear difference and key points to look for.
It's fascinating to think about the differences between strength and power and how strength doesn't just imply force but also velocity. Power on the other hand asks us whether a person is strong when time is unlimited vs unlimited. Thanks for the insightful video.
I thought those were super cool specifics as well since that isn't always something people think of when looking at an athlete. Understanding this can aid in how we approach programming for specific athletes and movements.
That is what really stood out to me! I also enjoy his examples in terms of olympic weightlifting and how that sport has the highest power output demand. I am curious to see what other sports also require high demand.
Being "in the hole" for some time really is amazing. When doing pause reps, you lose momentum that would help you bring the weight back up. It is amazing how strong people are.
I appreciate the videos you included at the end to help describe the concepts of strength, power, and work. It made it easier for me to understand the content.
Similarly, I feel it's so easy to mix these definitions up or not fully understand what they mean and describe so this lecture has been quite helpful elaborating this.
This video was very insightful on essential concepts like strength, power, and work while diving into important variables such as displacement, velocity, acceleration, and torque. These concepts are fundamental for understanding how the body moves and generates force during exercise, especially in strength training. Nice video!
One concept that stood out to me was the distinction between strength and power, especially in how they are applied in training. Strength seems to be more about the ability to exert force against resistance, while power is about exerting that force quickly. It makes sense that power would be more relevant in sports performance where explosiveness is key, like in sprinting or weightlifting. Thank you!
This was very helpful in differentiating power and strength. Understanding what each definition is comprised of allowed me to have a better interpretation of the concepts. This is something I will be thinking more about when going over the different biomechanical aspects of various movements.
This was a great reminder of the difference between strength and power. I'm amazed at powerful athletes who can move weight or their body weight quickly
It's very common for people to get power and strength confused. I've been guilty of doing the same myself before being educated. Something you spoke about in class that really stuck with me when it comes to differentiating the two was your example with powerlifting. This example probably stuck in my head more because of my own interest in powerlifting. You said that powerlifting should actually be called strengthlifting, while olympic lifting should be referred to as powerlifting because these would more accurately fit the goals of each of these sports.
the explanations of power vs strength was very well done. It helped to categorize them in my mind better. I have never thought of it like that, strength being a more slow and controlled application of force and power being more high velocity force.
I think establishing the difference between power and strength is super important. It provides insight into what plays into different methods of training.
I found this video helpful in reviewing how to differentiate strength and power because it is important to use these appropriately when working with your athletes.
I really enjoyed this video and found it quite helpful with the breakdown of displacement, velocity, acceleration, and torque when it comes to strength training, as well as how they correlate with lifting.
I really enjoyed the example about the taller vs shorter individuals who are back squatting. Especially how the one with the longer legs/taller is doing more work than the one who is shorter thus less work. This is important to keep in mind, or interesting to more so, when looking at people's maxes since those weights would feel different based on their proportions.
As someone who is not typically a weightlifter, it was really helpful to see the definitions for acceleration, strength, power, and work in a more scientific and specific definition.
This is a great foundational video for building knowledge around the differences between strength, work, acceleration, and power. I definitely like the review of strength versus power because I used to not be able to define them properly, but now I feel confident in defining them and knowing the differences. It is still important to know work and acceleration because those will apply to power.
Dr. Goodin, the most interesting part of this video was the examples between powerlifting, Olympic lifting, and that if pure force and explosive energy with just body weight. truly amazing humans. Another point I thought was interesting was the misleading title of the powerlifting sport. What a fun fact that helps me remember the difference of strength and power
I appreciate how the videos provided detailed examples of lifting along with definitions. I also found the explanation of the difference between strength and power helpful, as it clarified how these concepts are often confused with one another.
I found the distinction between power and strength to be very helpful! The explanation on how power lifting is actually a strength movement vs Olympic lifting placed the terms into a more understandable perspective!
I really liked the connection of strength and power to velocity and work. Connecting a bit more of energy/work into the situation was more clarifying, as well as being able to understand the affect of velocity on the two.
It is really cool to understand how I can apply my physics degree in the context of strength and conditioning! It's interesting to visualize the effects of torque and work produced by levers in the human body.
I found this video helpful in learning what the key differences are between strength and power since I often view these terms as similar or the same. It was also crazy to see the guy in the example video lift so much weight and then pull off a backflip!
The difference between strength and power can be confusing but it was very helpful to listen to you point out the key differences with the examples of powerlifting, weightlifting, and plyometrics.
Thanks for the material, I'm currently in my senior year of college. I really appreciate the real-life example you showing. A lot of times teachers or professors just give Definitions and concepts without showing how we can apply this material to our life. Gained Subs and Like.
I like how lifting examples were thoroughly given throughout the videos with all the definitions. I also like the explanation of the difference between strength and power and I feel it can be commonly mistaken for each other.
I found this lecture very interesting as it was a nice refresher to remind myself the true definitions of work versus power versus strength. The videos of the different types of athletes were very helpful to see these concepts in real life application. Something that I could use further explanation on would be angular displacement, more visual examples of this would be helpful.
It took me a few times to drum into my head the difference between strength and power. I understand it, but it's easy to accidentally mix them up sometimes. Seeing the powerlifters helped!
This video really highlighted the differences between strength, power, and work which is really important when it comes to strength and resistance training as these concepts can help us improve our movement.
This video helped me to better understand strength and power, this is exceptionally helpful when working with athletes when we are trying to improve their performance!
Currently started to read the Book for my future CSCS test, hopefully in December, and your content has really helped. I will be watching your videos all the way until the test!
I'm taking biomechanics and this makes it easier to reenforce my understanding of this material. Gives me a deeper understanding of the body and its strength and movements
Strength, power, and work are all terms commonly used in place of one another. Thank you for explaining the three and how they are similar but very different.
This video gave me proper insight on how to use the terms "strength" vs "power." I learned that strength is the capacity to exert force at any given speed (but limited by time), while power is the time rate of doing work.
Clarence Kennedy is one of my all time favorite weightlifters and UA-camrs in the fitness space. His strength is unreal and if anything his parkour or "tricking" is even better.
I really enjoyed the fact that you added visuals, it really helped me absorb all of the information. I find it interesting that we use thesse terms interchangeably without knowing the real definitions.
Understanding power and work from a biomechanical perspective really places the importance of how it can be Incorportated into an effective training program specific towards the physical activity.
Quite a bit of emphasis on speed when it comes to power ... a lighter med ball can only be thrown further or slammed harder if the person can generate enough force. Or, a power lifter slowly deadlift 650 lbs is exerting the same amount of power as the Olympic weight lifter cleaning 325 from the floor two times as fast. The question becomes about whether to train faster with lighter weights or heavier and slower when it comes to developing athletic power, such as vertical jumping, because the power outputs are often the same. Great videos, just thinking about this often when it comes to how best to train our athletes.
Yeah that's a great question Dave. For me it becomes a process of sequencing and specificity. As competition nears, training should trend toward the specific power spectrum of the sport within its anthropometric strength. The shotputter can increase body mass in the offseason, scaling up CSA and overall muscle mass without worrying about bodyweight constraints, transitioning to pure strength work, then strength-speed, and finally speed-strength. A sprinter would follow a similar periodization (with different exercise selection), but forgo the period of unrestricted hypertrophy. A powerlifter may follow that trajectory but remain in the strength phase, using strength-speed oriented power work for technique work and/or to create undulation within a microcycle. That's all just off the top of my head, but it's fun to think through how sport demands and athlete needs influence these programming/periodization decisions
I did not realize that strength was only defined for a given velocity and power was for when it was in a short time frame with and explosive velocity. Thank you!
I like how you stressed that we should be using "strength" and "power" appropriately! I also enjoyed the visual component of the various weightlifters.
Power and strength were two words that I knew were associated with each other but never completely understood the difference. This video helped me to understand that although strength is used with low speeds and power with high speeds, they both have to do with exerting force at a given velocity.
It was great to hear insight into the intricate differences between power and strength and how one describes someone as "strong" or "powerful" in the correct way. I thought it was interesting how you described the biomechanics of a tall person compared to a short person squatting.
This video was very helpful in differentiating between power and strength. Personally the height of the athlete performing the squat was very helpful in grasping work, and the videos were nice clarification and application of strength vs power. Thank you!
Really like how you talked about how power and strength are connected but clarified that while strength is associated with low speed, while power is with high speeds.
The power and strength seen in the example video is crazy to me! Those individuals are insane athletes and it was cool to see. I appreciated the review on terms in this chapter and found then to be very helpful to give a better overview on what was happening in the video.
I never knew someone can lift that much! It is crazy to watch someone be able to do that. It shows how they have to do explosive movements which is really interesting to me,
like how you stressed that we should be using "strength" and "power" appropriately! and also appreciated the visual component of the various weightlifters.
The examples you showed were really helpful in understanding the different types of strength and power in different muscles when doing specific movements! This video helped me realize that I can't always use the two words interchangeably
The videos you showed of the weightlifters were so awesome to watch! I also like how you pointed out that we should be using both strength and power properly
Watching the examples at the end really put everything into perspective. Especially the video of Ray Williams seeing him "in the hole". It seemed that he was there for a while, but you mentioned that was a fast squat for power lifting... that's crazy.
I think it is such a great example when discussing the idea of strength versus power...if I were to think about my 1RM in a back squat and then adding a jump under that weight, I think I would embarrass myself at the gym!
I found it very interesting that both strength and power are both used to measure the production of force and watching the famous shot putters training technique was very impressive.
It's cool to see you get excited about those guys and in the last clip of Gunther, totally insane! Looks like he didn't break a sweat and tbh looked too easy for him loll
Thank you so much for distinguishing the differences between strength versus power! I thought it was really helpful when hearing the olympic weightlifer versus powerlifter example.
That was crazy how they are all so strong. But I think that Clarence won since that backflip was awesome. Also I like like how you included that there can be negative work in biomechanics and that this is just seen with eccentric muscle movements as the force is acting on the muscle. But the powerlifter that is crazy how he can lift all that and not get hurt.
This part of the chapter in the textbook was rather confusing to me, this video cleared up a lot of things. Strength is the ability to exert force when time is not a limiting factor, Power is the ability to exert force when time is limited. Got it!
THANK YOU SO MUCH, Dr. Goodin. I am so lost in these chapters and your videos are incredibly helpful. I love the practical examples and additonal videos you provide in your videos. Please keep them up. THANK YOU THANK YOU!!!
You're very welcome Megan! I appreciate you watching. The plan is to continue cover more chapters starting this Spring. Best of luck with your studying 💪
I think his videos are super helpful as well! Sometimes the readings can be a bit much to comprehend, but the videos do an excellent job of heping me conceptualize the concepts.
Being able to understand the differences between strength and power is valuable, especially if you are working with athletes in a specific field, with specific goals in mind. Seeing the difference in the videos shown was insightful.
I agree, further insight's into an athlete's force-velocity profile can also be interesting when trying to program to maximize their power production.
Hi Zara! I agree with you, being able to differentiate between power and strength is valuable, especially when you are applying ti when working with athletes.
I agree with your insight! Especially working with athletes with specific goals, it is important to differentiate strength, power, acceleration, and work.
I agree that understanding the differences between the two is important. I appreciate how the professor explained the difference between the two. It helped me understand each of those terms better.
This was a super interesting video to watch. Usually understanding the difference between power and work is confusing, but having the definitions explained side by side was very helpful. Also the visuals are incredible, those guys spent years doing what they do and are experts in the sport.
Hi Keegan, I totally agree! It's crazy to see that much strength and power in action!
I also have struggled with differentiating power and work, so it was nice seeing them side by side. Hopefully it sticks for us now!
The Werner Gunthor was insane!
Agreed!
I also really enjoyed hearing the comparison of work and power side by side, which helped make it much easier to understand and differentiate.
Knowing the difference between strength and power was is super helpful especially when working with athletes who are trying to improve their overall performance.
Its odd how its called Powerlifting yet the term Power fits better with Oly lifting
yes this is a very fundamental concept that we all need to know in this industry
@@cadentomlin2646 agreed!
This is so true because different athletes will require different types of workouts than others!
I agree, it's very important to know the difference between the two when trying to improve an athlete's performance!
This video was incredibly helpful in distinguishing between power and strength. For me, the height of the athlete performing the squat really helped clarify the concept of work. The videos provided great clarification and practical examples of strength versus power. Thank you!
Yes I totally agree! That squat example was so helpful!
same, it makes sense that taller frames make visualization easier since important data points/areas of interest are spread out over a greater area
I agree!
I agree, that the visual that was painted regarding the taller athlete vs the shorter athlete helped me understand the concept of work as well.
I’m glad you discussed negative work. It made me understand how eccentric forces work a lot better.
Same for me! Never referred to eccentric forces as "negative work," but after watching this video, it makes complete sense!
Same here! Negative work wasn't touched on much in my biomechanics class last year, so this concept was new but it made sense.
Same here, these videos are great.
I didn't even know negative work was a term in biomechanics!
I really appreciated your emphasis on distinguishing strength from power. I think it is so important that we use these terms appropriately and your examples definitely helped to demonstrate a clear vision of the differences!
I agree! As fitness professionals, I feel we should know how to speak the fitness "language"!
I agree with you! The examples he gave throughout the lecture helped me see the differences and understand them.
I completely agree with you! These definitions were super helpful in understanding the rest of the concepts
I didn't know there was so many technical terms associated with biomechanics, but looking back at it, it totally makes sense due to how many vectors are being applied in the field. I appreciate the video as I have now a bigger understanding of the terminology!
Hey Siros! You are absolutely right! It's fascinating how the breakdown of technical terms can turn complex movements into measurable components that are much easier to understand. For me, gaining a deeper understanding of the terminology helps me understand how biomechanics is truly a mixture of science and athletic performance.
I can relate, but once you dive into the technical terms, it helps me understand the concepts, and everything starts to make sense.
I agree with your insight on this lecture!
I thought that the examples given in the video were great! It applied these biomechanics and physics topics of work, power, and acceleration to real life examples that apply to our future professions.
I agree! Having this knowledge can personally help us develop new and effective training methods!
Totally agree. Having this terminology and examples really helps with getting a deeper understanding!
i agree, they were pretty easy to follow
The examples were super helpful! It helps me learn concepts better when presented with examples that I can think of applying to real life. It helps me remember the material better!
Adding real-life examples makes the information provided to us more relatable.
I often feel that people mistakenly interchange strength and power, but this video clarifies the differences between them. Thanks, Dr.Goodin
Yes, strength and power are often confused and I agree that this video helped me to separate the two concepts. Thanks!
I appreciate how the three biomechanical concepts (strength, power, and work) were explained as influences for athletic performance and training designs. Knowing the differences of each concept allows training programs to be tailored to specific goals.
This is so true! Knowing this will help make training programs better, and more specific to the athlete's needs.

A backflip after a clean and jerk is insane! The athleticism is crazy
and he had some serious air time with that backflip
Discussing the biomechanical definitions of strength and power provides a better understanding when describing an athlete as "strong," where time is essential to consider. The videos of the athletes were a valuable addition to understanding strength and power.
I agree Jamie, the vides of the athletes were very helpful in understanding what these concepts look like in real life.

I agree and honestly I still mix up strength and power.
your videos always have so many examples which really helps me visualize different concepts
I agree! The visuals are definitely a great help as someone who prefers them over just talking lectures.
I agree, it helps me so much more when I am trying to learn the content.
I am a visual learner too so I also find this super helpful.
Dr. Goodin is the reason I applied at PLNU due to how well he teaches and explains things so I totally agree!
The added video clips are a great touch
Learning that height plays a part in how much that individual may work when performing a back squat was intriguing. I appreciate the example of comparing a 7-foot individual to a 5-foot individual. It really helped me grasp the concept better.

Hi Abby, totally! The examples were really inspiring as well
I agree - Always have to add some fun into learning!
Same here! Examples are super insightful and helpful for me, and these make it even more engaging!
I loved having the videos to visualize strength vs. power. I felt like it was a really concrete way to seeing these concepts at an elite level.
Agreed, as a visual learner these were very helpful
Definitely agree with you!
It's fascinating to think about the differences between strength and power and how strength doesn't just imply force but also velocity. Power on the other hand asks us whether a person is strong when time is unlimited vs unlimited. Thanks for the insightful video.
I also think this is fascinating!
This little difference goes a long way and I think it is really good we clarified this early on in the course
I also found it fascinating that strength and power reflect the ability to exert force at a given velocity!
I thought those were super cool specifics as well since that isn't always something people think of when looking at an athlete. Understanding this can aid in how we approach programming for specific athletes and movements.
I totally agree!

Being "in the hole" for some time really is amazing. When doing pause reps, you lose momentum that would help you bring the weight back up. It is amazing how strong people are.
Spoken like someone who's spent time down there. I definitely respect people who grind through it on their hard sets.
It's so hard to get out of there sometimes.
I thought this was super cool to see as well!
I appreciate the videos you included at the end to help describe the concepts of strength, power, and work. It made it easier for me to understand the content.

I’d never heard of negative work before, and this explanation was very insightful!
it's interesting because we aren't really due to use negative work on many occasions, but understanding the concept can only help!
I appreciate how the videos provided detailed examples of lifting along with definitions. I also found the explanation of the difference between strength and power helpful, as it clarified how these concepts are often confused with one another.
I found the distinction between power and strength to be very helpful! The explanation on how power lifting is actually a strength movement vs Olympic lifting placed the terms into a more understandable perspective!
I really liked the connection of strength and power to velocity and work. Connecting a bit more of energy/work into the situation was more clarifying, as well as being able to understand the affect of velocity on the two.
It is really cool to understand how I can apply my physics degree in the context of strength and conditioning! It's interesting to visualize the effects of torque and work produced by levers in the human body.
I found this video helpful in learning what the key differences are between strength and power since I often view these terms as similar or the same. It was also crazy to see the guy in the example video lift so much weight and then pull off a backflip!
the visual aids in this video were awesome and definitely helped clarify some of my confusion regarding strength, power, and work
I also agree, I am a visual learner and they definitely helped me achieve a better understanding
Those videos of the squats and the guy jumping were great additions and cool to watch!
i totally agree! it blows my mind how strong these individuals are
The difference between strength and power can be confusing but it was very helpful to listen to you point out the key differences with the examples of powerlifting, weightlifting, and plyometrics.
Thanks for the material, I'm currently in my senior year of college. I really appreciate the real-life example you showing. A lot of times teachers or professors just give Definitions and concepts without showing how we can apply this material to our life. Gained Subs and Like.
I 100% agree. Words on a screen don't translate to the real world examples we will see in this field
I like how lifting examples were thoroughly given throughout the videos with all the definitions. I also like the explanation of the difference between strength and power and I feel it can be commonly mistaken for each other.
This certainly allowed me to understand the biomechanical differences between different athletes, thank you!
I love that you included Clarence in this video haha. It was great to hash out all the different meanings of strength, power, acceleration, etc.
I found this lecture very interesting as it was a nice refresher to remind myself the true definitions of work versus power versus strength. The videos of the different types of athletes were very helpful to see these concepts in real life application. Something that I could use further explanation on would be angular displacement, more visual examples of this would be helpful.
It took me a few times to drum into my head the difference between strength and power. I understand it, but it's easy to accidentally mix them up sometimes. Seeing the powerlifters helped!
I really liked how you talked about strength and power and then gave multiple examples.
This video really highlighted the differences between strength, power, and work which is really important when it comes to strength and resistance training as these concepts can help us improve our movement.
This video helped me to better understand strength and power, this is exceptionally helpful when working with athletes when we are trying to improve their performance!
I agree!
Currently started to read the Book for my future CSCS test, hopefully in December, and your content has really helped. I will be watching your videos all the way until the test!
I'm taking biomechanics and this makes it easier to reenforce my understanding of this material. Gives me a deeper understanding of the body and its strength and movements
Strength, power, and work are all terms commonly used in place of one another. Thank you for explaining the three and how they are similar but very different.
I wasn't aware of the differences between strength and power, but your examples helped me understand!
This video gave me proper insight on how to use the terms "strength" vs "power." I learned that strength is the capacity to exert force at any given speed (but limited by time), while power is the time rate of doing work.
Clarence Kennedy is one of my all time favorite weightlifters and UA-camrs in the fitness space. His strength is unreal and if anything his parkour or "tricking" is even better.
I really enjoyed the fact that you added visuals, it really helped me absorb all of the information. I find it interesting that we use thesse terms interchangeably without knowing the real definitions.
Understanding power and work from a biomechanical perspective really places the importance of how it can be Incorportated into an effective training program specific towards the physical activity.
Quite a bit of emphasis on speed when it comes to power ... a lighter med ball can only be thrown further or slammed harder if the person can generate enough force. Or, a power lifter slowly deadlift 650 lbs is exerting the same amount of power as the Olympic weight lifter cleaning 325 from the floor two times as fast. The question becomes about whether to train faster with lighter weights or heavier and slower when it comes to developing athletic power, such as vertical jumping, because the power outputs are often the same. Great videos, just thinking about this often when it comes to how best to train our athletes.
Yeah that's a great question Dave. For me it becomes a process of sequencing and specificity. As competition nears, training should trend toward the specific power spectrum of the sport within its anthropometric strength. The shotputter can increase body mass in the offseason, scaling up CSA and overall muscle mass without worrying about bodyweight constraints, transitioning to pure strength work, then strength-speed, and finally speed-strength. A sprinter would follow a similar periodization (with different exercise selection), but forgo the period of unrestricted hypertrophy. A powerlifter may follow that trajectory but remain in the strength phase, using strength-speed oriented power work for technique work and/or to create undulation within a microcycle. That's all just off the top of my head, but it's fun to think through how sport demands and athlete needs influence these programming/periodization decisions
The clarification between strength and power was helpful and fascinating when related to real-life examples.
I did not realize that strength was only defined for a given velocity and power was for when it was in a short time frame with and explosive velocity. Thank you!
This was a great review of some of the main biomechanical terminology and concepts, I had forgotten about.
I like how you stressed that we should be using "strength" and "power" appropriately! I also enjoyed the visual component of the various weightlifters.
Knowing the differences between strength and power is essential, and I agree going over this helped me as well.
Yes, this is super important! Even more so, though, it's done in a way that we can relay to athletes to help them.
Power and strength were two words that I knew were associated with each other but never completely understood the difference. This video helped me to understand that although strength is used with low speeds and power with high speeds, they both have to do with exerting force at a given velocity.
It was great to hear insight into the intricate differences between power and strength and how one describes someone as "strong" or "powerful" in the correct way. I thought it was interesting how you described the biomechanics of a tall person compared to a short person squatting.
This video was very helpful in differentiating between power and strength. Personally the height of the athlete performing the squat was very helpful in grasping work, and the videos were nice clarification and application of strength vs power. Thank you!
Really like how you talked about how power and strength are connected but clarified that while strength is associated with low speed, while power is with high speeds.
I agree! Often times, it can be confused for the other!
I love seeing actual videos in videos...can really help us understand the topic more!
Thank you for clarifying the difference for strength and power as well as providing examples for each. I enjoyed the videos at the end too!
The power and strength seen in the example video is crazy to me! Those individuals are insane athletes and it was cool to see. I appreciated the review on terms in this chapter and found then to be very helpful to give a better overview on what was happening in the video.
I really enjoyed the real life examples accompanied by the videos. Those guys are insanely strong
Seeing these concepts are a great refresher from ex phys
This video was super interesting I really liked how there were a bunch of different lifters included in the video!
I never knew someone can lift that much! It is crazy to watch someone be able to do that. It shows how they have to do explosive movements which is really interesting to me,
like how you stressed that we should be using "strength" and "power" appropriately! and also appreciated the visual component of the various weightlifters.
The examples you showed were really helpful in understanding the different types of strength and power in different muscles when doing specific movements! This video helped me realize that I can't always use the two words interchangeably
Thank you for clarifying the difference between strength and power, the videos were a helpful visual in seeing the differences.
I really liked how you included videos showcasing both strength and power. This was a great way for me to put a visual to the words and definitions!
The videos you showed of the weightlifters were so awesome to watch! I also like how you pointed out that we should be using both strength and power properly
These definitions and explanations are so helpful! Strength and power can definitely get confusing since they are so intertwined. Thank you!
I enjoyed learning how torque and angular displacement work together to create rotation.
I appreciated the clarification on the difference between strength and power. I feel like I always mix them up.
Watching the examples at the end really put everything into perspective. Especially the video of Ray Williams seeing him "in the hole". It seemed that he was there for a while, but you mentioned that was a fast squat for power lifting... that's crazy.
I think it is such a great example when discussing the idea of strength versus power...if I were to think about my 1RM in a back squat and then adding a jump under that weight, I think I would embarrass myself at the gym!
I found it very interesting that both strength and power are both used to measure the production of force and watching the famous shot putters training technique was very impressive.
It's cool to see you get excited about those guys and in the last clip of Gunther, totally insane! Looks like he didn't break a sweat and tbh looked too easy for him loll
Thank you so much for distinguishing the differences between strength versus power! I thought it was really helpful when hearing the olympic weightlifer versus powerlifter example.
That was crazy how they are all so strong. But I think that Clarence won since that backflip was awesome. Also I like like how you included that there can be negative work in biomechanics and that this is just seen with eccentric muscle movements as the force is acting on the muscle. But the powerlifter that is crazy how he can lift all that and not get hurt.
This part of the chapter in the textbook was rather confusing to me, this video cleared up a lot of things. Strength is the ability to exert force when time is not a limiting factor, Power is the ability to exert force when time is limited. Got it!
I had never heard of the term negative work before. That was super interesting.
Back in the 70's I used to do some negative sets. Not a fan.
Same, I agree its interesting to hear the terminology used.
THANK YOU SO MUCH, Dr. Goodin. I am so lost in these chapters and your videos are incredibly helpful. I love the practical examples and additonal videos you provide in your videos. Please keep them up. THANK YOU THANK YOU!!!
You're very welcome Megan! I appreciate you watching. The plan is to continue cover more chapters starting this Spring. Best of luck with your studying 💪
I think his videos are super helpful as well! Sometimes the readings can be a bit much to comprehend, but the videos do an excellent job of heping me conceptualize the concepts.
