    So amazing how we were created so specifically- the fact that muscles have different pennation of fibers to be able to perform different functions is so crazy! Such a small detail but makes a huge difference.

      I know! Awesome that each muscle has it's own specific function, and yet there is still so much variability between individuals

    This video allowed me to clearly understand the ways a muscle produces force through its motor units. Thank you!

    It is so interesting to learn about all of the components that go into strength. How our bodies were created truly amazes me.

  • @dimitricarrion6145
    @dimitricarrion6145 Před rokem

    I liked how you explained why our muscle fibers run in the pennate formation rather than just running down a straight line.

    I enjoyed learning about the strength-to-mass ratio. It made me think of how the UFC always has their "pound for pound" best fighter labeled, and usually it is a smaller fighter.

  • @julianasum8481
    @julianasum8481 Před 7 měsíci

    This video gave me better insight on how neural control and muscle cross sectional area can affect strength and power. Additionally, I enjoyed learning about the applications of strength and power on different types of athletes.

  • @macynunez4455
    @macynunez4455 Před 7 měsíci

    I have learned about pennation before but I never thought about how the muscle fibers don't necessarily directly align with the muscle's line of pull and because of that, it is able to exert a greater force of contraction! Such an interesting concept along with the strength-to-mass ratio!

  • @user-me5er1gr9h
    @user-me5er1gr9h Před 11 měsíci

    I liked the segment on muscle pennation and its uses. Also the breakdown of the strength to mass ratio and the example of the powerlifter vs the sprinter was interesting.

  • @celinegriffin3244
    @celinegriffin3244 Před rokem

    I like how you pointed out that smaller athletes have a higher strength ratio than larger athlete, with the example of the back squat where the smaller athlete doesn't have to produce more of a load because they are closer to the ground compared to someone who is taller and need to travel down further

  • @joshcombs123
    @joshcombs123 Před 11 měsíci

    The force output example was very interesting and helpful. A good strength base carries over into other movements, not just heavy, weight bearing activities.

  • @kylesands9693
    @kylesands9693 Před 11 měsíci

    It was really cool to learn about all the different muscle fiber arrangements! I had no idea, such a cool little detail.

  • @jamarmack9626
    @jamarmack9626 Před 2 lety

    It was really interesting to learn about the strength to mass ration because before learning this, I had never even thought about the weight someone is lifting relative to their own body mass.

  • @audreyoates3242
    @audreyoates3242 Před rokem

    It was interesting learning about the arrangement of muscle fibers. I've never learned in-depth about fibers before, great video!

  • @DevanneyBoyd
    @DevanneyBoyd Před 7 měsíci

    It is fascinating how many factors impact muscle strength and power; one of the most interesting is the strength-to-mass ratio.

  • @luciavaldez2601
    @luciavaldez2601 Před 7 měsíci

    The image of muscle arrangement really brought everything to light! I liked how there was not only images of how the muscle arrangement looks on its own, but also with examples of where that type of muscle arrangement can be found in the body.

  • @wyattcarlson7504
    @wyattcarlson7504 Před 7 měsíci

    The strength to mass ratio is always a super interesting topic. For example some athletes might have a smaller mass, but an overall higher strength to mass ratio.

  • @rozalynnlarson8835
    @rozalynnlarson8835 Před rokem +2

    I liked learning about the strength-to-mass ratio. I think it's really interesting that smaller athletes typically have a higher ratio than larger athletes.

  • @everoche3754
    @everoche3754 Před 11 měsíci

    This video is a combination of so many different classes I have taken throughout the years here! It is cool to see them all in one video and how intertwined each topic is with another.

  • @jasonpena3556

    Strength to max ratio was something very new and awesome to learn more about !

  • @joyshang5670
    @joyshang5670 Před rokem

    Wow! I never knew that people in the lower weight class have a higher strength to mass ratio. It was really interesting to learn and how their body structure helps them operate/perform.

  • @saeternj
    @saeternj Před 11 měsíci

    It makes sense why smaller weightlifters are so much more explosive than larger weightlifters. Thanks Dr. Goodin!

  • @jadenrea1109
    @jadenrea1109 Před 7 měsíci

    I think the different types of muscle arrangements are so interesting as they all serve such a specific role. The figure showing the different types of muscle arrangement and how each of them is associated with different parts of the body was great and very cool.

  • @madelinejewelnebril2871
    @madelinejewelnebril2871 Před 11 měsíci

    It was interesting to learn about the different muscle fiber arrangements and how they each allow for different contractile characteristics.

  • @evakoutelieris1633

    I found the arrangment of the muscle fibers very interesting!

  • @BrianaReynoso
    @BrianaReynoso Před 7 měsíci

    I found this to be very interesting! Strength to mass ratio was cool to learn because usually we would think the taller athlete would have a higher ratio.

  • @clairemasterson6031
    @clairemasterson6031 Před rokem

    The explanation of strength to mass ratio was very interesting to me and something I've never really thought about before. Like while watching the olympics last summer but perhaps in that example they make it look so easy, even though I know better.

  • @MatthewDuPrey325
    @MatthewDuPrey325 Před 7 měsíci

    I find the strength-to mass section to be very interesting because I know from high school that it isn't always the bigger guys who are able to be the strongest or able to jump the highest but the smaller guys can sometimes be just as strong if not stronger.

  • @emilywalker9462
    @emilywalker9462 Před 7 měsíci

    Reviewing the angle of pennation was super helpful! I always seem to forget this and this was a fantastic refresher!

  • @lucamarin8565
    @lucamarin8565 Před 7 měsíci

    I found the strength to mass section very interesting. I feel that we commonly assume that the more mass an athlete is the less likely they are to jump high yet in many scenarios the opposite can occur.

  • @Fitness_coreyt
    @Fitness_coreyt Před rokem

    Thank You so much Sir, I haven't applied for CSCS Course yet as I was checking My ability if I can do This or not but by providing and explaining such great Course for free is already motivational for Me.

  • @madelinehernandez8838
    @madelinehernandez8838 Před 11 měsíci

    Relearning muscle length while at rest, stretched, and contracted was a good reminder. These muscles are going to generate the greatest force at resting length.

  • @user-sd3sv7uq7f
    @user-sd3sv7uq7f Před 7 měsíci

    Learning about the body has always been an amazing thing for me! The number of different muscles like radiate, bipennate and inupennate makes an of how incredible the human body is !!

  • @moirabryson5042
    @moirabryson5042 Před 7 měsíci

    I didn't realize how important the strength to mass ratio was important when it came to sports events, but it does make sense that there must be a peak point to when it's the best and after that the the ratio would decrease due to the mass of the individual. Thank you!

  • @coreycollier973
    @coreycollier973 Před 3 lety

    It is interesting to learn how there is not a set guideline for a certain athlete's strength to mass ratio and that it can only really be found through trial and error.

  • @makennakaczmarczyk7563
    @makennakaczmarczyk7563 Před 11 měsíci

    I think it's interesting to learn how biomechanical factors are affected in human strength by the muscle length. Muscles can generate the greatest force at a resting length because of the number of potential crossbridges.

  • @alannabergherm8046
    @alannabergherm8046 Před rokem

    I found the sections about body size and the strength to mass ratio very interesting! I never even thought about how there could be such a thing as "too much muscle"!

  • @tianguyen3897
    @tianguyen3897 Před 2 lety

    I found it super interesting to learn about body size in the "strength to mass ratio" section! I would never have thought that given constant body proportions, a smaller athlete would have a higher strength-to-mass ratio than a larger athlete.

  • @ChynnaKifer
    @ChynnaKifer Před rokem

    It is crazy how strength to mass ratio plays a part in different sports! Thank you for the video!

  • @matthewwadley4348
    @matthewwadley4348 Před 11 měsíci

    The strength to mass ratio was pretty interesting as to how your own body mass increases more rapidly than muscle strength which in the long run makes a ton of sense.

  • @torilucht5871
    @torilucht5871 Před 11 měsíci

    The strength-to-mass ratio was a new concept to me but it makes so much sense! Often people think the bigger the person would be the strongest but in the case of body size the smaller athletes tend to have a better strength-to-mass ratio. This is an interesting concept!

  • @wyattsimms4472
    @wyattsimms4472 Před rokem

    I enjoyed learning about how the factors that effect performance in resistance training. I am excited that we are starting to get deeper into the resistance training programming side of things!

  • @jakegellatly8261
    @jakegellatly8261 Před 11 měsíci

  • @kennyvogan5673
    @kennyvogan5673 Před rokem

    There is a lot more stuff to take into consideration for an athlete and their strength that is above how much they can accelerate or move weight as a baseline. The strength to mass ratio makes a lot of sense, even more so from a gymnasts perspective to see why gymnastics mainly works for those that are short. Tall athletes can do the same stuff, but shorter gymnasts just have a greater strength/mass ratio.

  • @TRamos-pl6oo
    @TRamos-pl6oo Před 11 měsíci

    i thought the strength to mass was very beneficial to learn about. It also makes a lot more sense how when strength is higher and mass is lower, those people are able to reach the needed force much quicker

  • @cameransherwood5157
    @cameransherwood5157 Před rokem

    the strength to mass ratio is so unique to me. it makes sense why a smaller track athlete would tend to have a higher strength-to-mass ratio then a body builder though. I dont know why I always had the idea that "Weight moves weight" in my head so I would think that the heavier athlete would have the higher ratio which I now know is incorrect!

  • @caleighgarcia7792
    @caleighgarcia7792 Před rokem

    I think that the strength-to-mass ratio is very interesting. It now makes sense to me why some people who are super tall cannot lift as much because the weight has to move much further. This put that into perspective for me, thank you!

  • @aribhalla9820
    @aribhalla9820 Před 3 lety +1

    It was interesting to learn about how joint angles are related to muscle action/power.

  • @avajgallo
    @avajgallo Před rokem

    I always wondered why exactly those short sprinters were always so fast and why people thought I would be able to run fast with my "long legs" haha. Makes a lot of sense now.

  • @jackmalone5800
    @jackmalone5800 Před rokem

    The idea of indiscriminate hypertrophy was really interesting to me. Seems like it is all very goal specific using the example of a bodybuilder vs a sprinter with bodybuilders just wanting hypertrophy at all costs while a sprinter is only concerned with running faster and hypertrophy is a byproduct of that training.

  • @milandiklic1080
    @milandiklic1080 Před 11 měsíci

  • @emilydonahue8216
    @emilydonahue8216 Před 3 lety

    This was super interesting! There's so many factors that go into analyzing athlete's strength. The strength:mass ratio is so interesting, and makes so much sense!

  • @michaelrogowski62
    @michaelrogowski62 Před 3 lety +2

    It makes sense that you said that the smaller the athlete, in general, are stronger when it comes to strength to mass ratio. I thought of Naim Süleymanoğlu able to lift 3 times his body weight at 4ft 10in compared to Lasha Talakhadze at 6ft 6in not even able to lift twice his bodyweight.

  • @hannahb872
    @hannahb872 Před rokem

    The "strength to mass ratio" is one of the factors I found pretty interesting to know how it affects acceleration. Its fascinating to know how much it impacts the muscular power and strength in an athlete performance.

  • @davidhaynes3269

  • @thelmasepulveda4481
    @thelmasepulveda4481 Před rokem

  • @bojak76
    @bojak76 Před 4 lety +1

    The concept that smaller weightlifters can lift more (percentage in relation to body weight) versus a larger weightlifter is not a new concept to me, however the reasons why were unknown. I basically just assumed it was because of gravity. The explanation of strength-to-mass ratio clears everything up for me now. Finally!

  • @hayleesaurette1798
    @hayleesaurette1798 Před 2 lety

    This video helped me better understand that strength and mass have an interesting relationship, especially when it comes to each individual sport. I thought it was crazy that you mentioned a track and field athlete might have a better strength to mass ratio than a massive body builder because they strengthen only the muscles they use the most, rather than every muscle group.

    @Adam.gates_ Před 11 měsíci

    Muscle pennation is an intriguing topic. Will we go over training muscles by biasing certain fibers according to their pennation? I see a lot of fitness gurus talking about that, but Dr. Mike has strong opinions against it.

  • @jakegonzales1367

  • @emmasanchez5975
    @emmasanchez5975 Před 3 lety +1

    It's interesting how smaller weightlifters can lift more! I never knew that because I thought it would be harder on their bodies instead. I love the demonstration with the pencil it helped tie things together.

  • @evaozimec
    @evaozimec Před rokem

    Interesting to learn that shorter/smaller athletes have a higher strength to mass ratio because they don't have to produce as much work when lifting a load because it's traveling a shorter distance!

  • @cutetwinkie47

    It is very interesting that sprinters have a better strength to weight ratio than a body builder which makes a lot of sense due to the amount of power a sprinter must produce with less body weight than a body builder.

    Struggling with pennation and the velocities. It seems getting a solid understanding might involve my doing the calculations again and again. Some time require exercise, lol.

  • @iyappans5259
    @iyappans5259 Před 3 lety +1

    Hi sir, Strength to mass ratio little confusion sir, I understand Strength/Mass = Force/Mass = Acceleration, when Force increases acceleration will increase, mass increases acceleration will decrease. Your Example 70kg, 140kg I can’t understand please explain sir

  • @cjbuenviaje
    @cjbuenviaje Před rokem

    It is fascinating how smaller athletes can lift more due to their body weight. How can you make it so that taller people can lift as much weight or are they just naturally not able to lift as much muscle unless they train more?

  • @ameliabrock
    @ameliabrock Před 7 měsíci

    I wonder about the strength to mass ratio of professional ballerinas and bodybuilders. I really wish I could see how they compared considering the strength dance takes and the (unhealthy) emphasis on being as light as possible.

    Hi Dr Jacob
    i have specific question related to chapter 2 ( application of resistance training ) / the greatest muscle torque means the greatest muscle force , or not true ?
    During the biceps curl exercise , the biceps apply the greatest muscle torque at the position of 90 degree to control the weight, which means it plays the greatest muscle force , there's a confusion on the norms , thank you for reply and explanation .

  • @keonihughes4242

    What would be the best way to lengthen the hamstrings for a deeper squat? Or any other muscles, that when lengthened, allow for a deeper squat?

    • @DrJacobGoodin

      Dynamic mobility routines, also, deep pause squats and slow eccentric squats. Specifically for hamstrings, strict paused RDLs are great.
