  • Is sumo deadlift cheating? (my thoughts on Jeff Nippard's video)
    Sumo deadlift is considered easier than the conventional deadlift. However, Jeff Nippard recently made a video where he attempted to explain through science that the sumo deadlift is not easier than the conventional. Jeff concluded that ''there is no sound evidence to support the idea that the conventional deadlift is harder than the sumo'''.
    Although he claimed to support most of his arguments with science I think he missed some basic points on this topic and I made this video with the intention of adding to the subject.
    This video is a science-based response to Jeff Nippard and a short presentation of some biomechanics rules on the sumo deadlift.

    Physics alone shouldn't be considered, you have to take into account biomechanics as well,
    lifting 100kg by 20cm conventional is easier than lifting 80kg by 20cm with one leg only, even though the amount of joules is smaller, we need to take into consideration the work done by the involved muscles. (Which is the tricky part)
    lifting

    • @YiannisChristoulas
      @YiannisChristoulas  ปีที่แล้ว +2

      Nothing really tricky here. We compare similar movements with both legs. The sumo uses more the quads which are bigger muscles. the strength of a muscle is determined mainly by its cross-sectional area. Thus the quads are the strongest muscles of the body. Sumo uses more quads and conventional more lower back. Physics and geometry are only some (not the only) parts of the equation I agree
      Nothing is a stand alone component. The same goes with weight. Weight (intensity) is one of the predominant training variables. However (with your way of thinking) if you compare lifting 80kg with squat is easier than 50kg bicep curls, thus weight is not so important too.

      Also, his argument is tautological if not a non-sequitur. Tautological in that, he says conventional gets you an extra 3 inches and the same weight for an extra 3 inches gets you more joules/kcal, but the only reason we're asking the question is because sumo is cheating and you would, presumably, be lifting more weight 3 fewer inches. In the 80s, Miller Lite (beer) used to run commercials where the two sides argued "tastes great' vs. 'less filling'... this is that argument. Whether 'more work' is 'more weight' vs. 'further distance'. This tautology is (not) cogent because the physics is a non-sequitur. The athlete's fitness or capability may depend on joules/kcal and physics, but the determination of a successful lift does not. Plates, bodyweight, and lockout are it, the height the weight lifted, assuming lockout, is irrelevant.

    I measured the approximate angle of the arms to the spine and got 47° for sumo and 65° for conventional. Taking the sine of both of these results in 20% less torque on the hips with sumo, treating the spine as a lever and the hips as a fulcrum.

    The work equation simply doesn't "work" in this circumstance because your leverages are different. So even though less work is done against gravitational forces that doesn't mean its actually easier to reach the locked out position and this is all because of the different leverages. Example imagine lifting a 100kg fridge up by a height of 1m with a just a rope. Now imagine you use a pulley or a lever to lift it 1.5m. Depending on the set up less force can actually be required despite to lift the fridge. This is just one reason why work done isn't a sound argument for it being easier.
    Think about narrow vs wide grip pull ups. A wide grip pull up is generally harder than a narrower grip because of the mechanics of the movement.

I gave a mechanical example of why work done doesn't accurately portray the difficult of a lift or how much force the person had to produce. The joints are not moving in a straight line there are levers at play. All work tell us is how much energy was transfered into gravitational potential energy not how difficult the lift was.

Open grip is a lot harder due to the different mechanics but one thing that is easier compared to the close grip is the less work needed. However this difference is not even close in making up for the difference that occurs through the mechanics on that particular example. See what I mean? The open row still has an easier work done that affect to a degree the exercise.
      In biomechanics when we compare two different movements (thus different mechanics, leverages) we include all the variables. Now whether this variable plays a big or a small role in another discussion.
      This video was only a demonstration that there is sound evidence to support this. Now if you don’t believe that these effects can make a difference, ask Jeff why he said on his video that in the same weight he has a smaller RPE on the sumo, thus feeling it easier.

      I remember well that point and it was interesting because it felt like admitting that sumo is indeed easier than the conventional. It looks like an argument from the other side of the debate. If you feel less intensity on the sumo and you need to increase the weight to feel the same with lower weight on the conventional, then this is pretty much it.Jeff just admitted that sumo is easier. So if for example at 100kg on the conventional your RPE is 8 and at 100kg sumo is 7 then the conventional is harder. If you have to lift 115 on the sumo to reach RPE 8 then your RPE will rise again on the conventional too. I wasn’t sure why he put that on his video. Nevertheless I wanted to respond with more “measurable aspects” of the problem which are not debatable.

      By widening your stance you bring your arms closer to the bar. This means less effort from the hips to get you in the right position.
      On another note, Imagine having plates that are special according to your height and bring the barbell close to your knees like a 160cm athlete already is with the standard plates. To replicate the same mechanics you need wider bar and lift from blocks.

If not it’s from a guy who recently passed away named Louie Simmons who founded westside barbell. He came up with a system that allowed you to max out 1-2 times weekly while also doing high volume which gets rid of the issue that comes with traditional strength hypertrophy blocks. It works because you change the variation of the lift you max on, since the different variations use our muscles different we avoid getting snapped up. By extension if some of those muscles are weak links then when you bring them up the main lift is gonna increase as well. Westside/conjugate developed a bad rep but a guy called Alpha Destiny who is most likely one of the few real naturals on the platform has been debunking the main critiques like needing more excessive specificity, not being able to do enough volume, whether or not using lots of variations even works. To your question about sumo I wouldn’t say it’s so much that sumo or a lot of these variations are the best at developing anything. More so to do with the fact the specific way it stimulates might be a weak link for you. Pretty much any exercise you could argue you don’t necessarily need to grow a muscle. You could never do benching and instead do weighted push ups and weighted dips. But that doesn’t mean including the bench in addition to those wouldn’t make you even jacked and strong.

    If your comparing 1 rep max strength than Energy/work (Joules) doesn't really matter, it's force you should be worried about.
    You miss a lift at your weakest spot, where the force of the bar and weight is now greater than the force your body can produce against the bar.
    The human body can produce maximal force for at least a couple seconds, making worrying about energy/work done or rather ROM a concern only for multiple rep comparisons where the extra work done in conventional will likely fatigue you faster than sumo.

      Thanks for your comment, my point here is that there IS ''sound evidence'' that sumo is easier in a way. About the starting position, that was my second point about but I didn’t want to expand and make the video longer. For every centimeter that your feet go to the side the knee comes closer to the ground, it’s like lifting from blocks. In addition, there is also a long-term effect to this. If with sumos you exert less work you can train more in every training session which will result in more sports-specific adaptations. 10 reps of conventional were 12 reps of sumo in terms of work, imagine how that accumulates overtime on a training cycle. In addition, most of the athletes (I agree) fail at starting position but not all. To be honest, I could make a video with a ''hundred'' mechanical reasons why sumo is easier at starting position, this was just a quick response to Jeff Nippards comment.

      At higher weight classes we see lifters often have closer squats to deadlifts. This is likely due to as humans get heavier they hold more mass in the torso including spinal erectors which allows for more torso rigidity. Something similar could be happening with deadlifts that smaller sumo lifters have weaker relative to weight spinal erectors compared to heavier lifters.
      Not to mention that as humans get bigger mobility goes down so it is unlikely that as many large lifters could take advantage of sumo.

      @@lawsonsippola2228 This conversation gets better and better and it’s clear that you have experience on the topic. However experience not based on relevant to the subject academic education can be extremely misleading, because these arguments are based only on the outcome. This is what happens with most of these TH-camrs.
      Regarding your first point: One, Do you really think that that bigger dudes know about this (geometry rule) or have ever thought about this? Honestly, did you ever hear that by someone else except me? Can you point out any article that talk about it in any fitness blog? Jeff Nippard lifts his entire life with sumo, he is a very well thought athlete and admitted that he hasn’t thought about this. Second, if a very large dude has been training his entire life on conventional, switching to sumo for a year just to make a record, wouldn’t be enough time to create similar adaptations. We would see everyone lift the same if they were the similar training years too on both styles.
      Regarding your second point: Even if we assume (with no actual evidence), that shorter athletes have less strength (spinal erectors) in general because they have less mass on the torso, this would mean that the mass of the torso plays a vital role. Then, the fact that shorter athletes lift in every repetition less mass on their torso would again play a vital role in counterbalancing their ‘’weakness’’. Shorter lifters lift much less than taller ones, and much of this ‘’less weight’’ is due to less mass on the torso. So even if they had proportionally less strength on the spinal erectors they would counterbalance it with less mass on the torso to lift. Of course these are all assumptions, geometry is geometry.
      Third point: Humans don’t get less mobile as they get bigger, it happens that I’ve read every paper on flexibility that exists. They just move less due to the increased weight and forces which results in a less active range of motion. If a shorter athlete moves less than they do, he will have the same result. Bigger athletes could increase their active range and do wide sumo easier.
      Bonus: One of the real issues is the point that the barbell starts in relation to the body of a shorter vs a taller athlete. If a shorter athlete starts with the barbell almost on his knees while a taller at the middle of his lower leg then wouldn’t that need mechanical alteration?

    People down in the comments talk so much about theories like going to the gym is a physics contest. Dudes, just get your asses up and try if for yourselves.
    - If I do deadlifts the regular way, I can do 5x6 reps, 200kg.
    - If I do deadlifts sumo, I can do 4 to 5x6 reps, 240kg (yes, that is 40 kilos more, no spelling error!).
    - If I do deadlifts sumo with weights resting on additional plates, I can do 4-5x6reps, 250kg.
    And all that despite sumo, according to the video, is not optimal for me since I'm 1,87m tall. So try it. You'll have the same results (maybe not the same weights, but surely the same weight DIFFERENCES), no matter what your calculus says.

    The amount of energy used while doing the work is the same! more distance just means that you gotta keep putting the same amount of energy (so the inertia doesnt go way) for couple more seconds! you also gotta take in count people's anatomy, some people cant get in a sumo stance with out pain, or mobility restrictions, and other people cant get in a conventional stance without pain or mobility restrictions! thats why you got people like Halfthor and Eddie who had said that they had tried sumo and it doesn't feel good for them, and there is people like "most sumo pullers" that had tried conventional but it doesn't feel good for them! I myself tried sumo for about 6 months, never was able to find a position where I felt my glutes firing, I did manage to sumo about 50 more pounds than what I use to in conventional, but once I swap back to conventional, I was rep[ my previous pr for 5, and added 30 more pounds to my sumo pr but in conventional!
    now I practice both, when I see I am stuck with one I switch to the other, and it has being working well for me, even when I feel some pain while doing sumo.

    These are some really interesting counter arguments, but i feel like some of jeffs main points were missed. I would be curious about how you feel in regards to his comparison of deadlifts and the bench press, specifically how people dont apply the same idea to bench pressing.
    In addition, I don't think jeffs argument is that sumo is easier, he openly ackoweldges this in his video. Jeffs argument is that sumo is easier for some people, while conventional is easier for others, and that everyone should do the lift they feel is best for them. I did however like your inclusion of physics as a mechanical engineer, myself!

      Your experience is interesting, and it highlights a key aspect of scientific research. Science aims to identify trends and patterns that apply generally, rather than focusing on individual cases. What works for one person might not work for another, and that's perfectly normal. For instance, in a study of 1000 people, a particular drug might effectively alleviate headaches for the majority, but it might not work for a smaller group, say 50 people. This doesn't negate the drug's overall effectiveness. Similarly, while you may perform better with conventional deadlifts, this doesn't invalidate the science-based reasoning about Sumo deadlifts. Science is all about understanding general patterns while acknowledging individual variations.
      In addition, it's important to consider personal training history and skill level. If you've trained more extensively in one style over the other, or if there's a disparity in your ability to perform each exercise optimally, that could also influence your personal experience.

    You are correct as far as you go but it's not the whole picture. "Cheating" is a concept that only applies to competition not "training" so there are some additional factors to consider. In training (sets of reps) the energy/work (in Joules) is relevant as are the, associated, depletion of glycogen and buildup of lactic acid - so sumo would allow for more reps before failure. Obviously if you want to do a certain amount of work in training you would need more sumo reps than conventional reps. HOWEVER, the force required to pull 100kg is always going to be 98.1 kN (on Earth) regardless of the range of motion. For a 1RM (competition) lift aerobic capacity, glycogen availability, & lactic acid buildup are all irrelevant - simply "can you apply the requisite force?" In a competition there is a long rest interval between efforts. But the big difference is that in sumo you use your quads a lot more and they are very strong (i.e. able to exert a high force). Also, in addition to the stance width, a shorter limbed lifter has mechanical advantage in the sumo style. In other words one is closer to using "leg press" muscles in sumo (I can currently leg-press about 3x my deadlift) which is advantageous. The bottom line is - in training, cheating is not an issue - in competition, the question is "is it within the rules?" - I don't think that sumo is in the same category as "lifting suits" etc., it is just a case of different athletes using techniques that suit their physiques. Understand your body and use the technique(s) that meet your training and/or completion objectives.

    • @YiannisChristoulas
      @YiannisChristoulas  ปีที่แล้ว +1

      A few things here
      1) This is not a video with the whole picture of why sumo is easier than the conventional, but only a response to the ''not sound evidence'' of another TH-camr. So my purpose of this video was to present reasons based on extremely sound evidence. I just presented the two most basic that can be found even in books like the Essentials.
      2) But of course, there are many more, and I completely agree with the quads that you mentioned, as I have explained over and over in the comments of this video. Still, there are many more reasons.
      3) As I said in the video we use the word ''cheating'' just to say it's easier. We don't actually suggest that someone is cheating somewhere.
      4) Work is not only relevant to glucogen depletion (+ PCr) and lactic acid build-up but it is tightly connected with the development of peak strength in the long run. Before I explain just a small note... lactic acid is an old term for what you wanted to explain, today it is well understood that the build-up of hydrogen ions causes the muscle to become more acidic, thus creating this feeling of burn and pain (you can find more here: Robergs, R. A., Ghiasvand, F., & Parker, D. (2004). Biochemistry of exercise-induced metabolic acidosis. American journal of physiology. Regulatory, integrative and comparative physiology).
      Now the main driving factor of muscle development and strength is volume (on the same intensities). If you can (by having lowe ''work'') accumulate more volume during a given period on the same weight with sumo, then you will of course develop more adaptations to maximal strength. And this difference is crazy. In just 12 sessions of 9 sets-10 reps the ''sumo lifter'' will accumulate 216 more reps on the same weight as a ''conventional lifter'' with the same amount of work. If that is not relevant to increasing rapidly strength and competing in a 1RM competition, I can't imagine what else would be. This is entirely based on work and energy expenditure.

    Yes I agree with the fact that you need less total work to perform sumo deadlift, but you don't take into account that more effort is required to the quads with sumo than with conventional, which means that if someone has weaker quads and a stronger lower back, sumo will still be harder than conventional, that's why it depends that much on the lifter.
    The math would be : let Wqs be the work performed by the quads to lift a certain weight in sumo deadlift, Wls the work performed by the lower back in sumo, Wqc by quads to lift the same weight in conventional and Wlc by lower back in conventional. We do have : Wqc + Wlc > Wqs + Wls. But we also have Wqs > Wqc (which necessarily implies Wlc > Wls of course). We can have a lifter that can lift Wlc and Wqc (making them able to pull conventional) but unable to lift Wqs (making them unable to pull sumo)

    • @YiannisChristoulas
      @YiannisChristoulas  ปีที่แล้ว +5

      Hi Nicolas! Thanks for your comment but unfortunately this is not the case. If this was true then close grip bench press wouldn’t be harder than wide grip. If someone had stronger triceps than pecs then the close grip bench would be easier right? So no one could argue that the one is harder than the other in any exercise, simply because some can be better at it. Same way Front squat wouldn’t be necessarily harder than back squat.
      In reality, some muscles are stronger than others for all humans. The strength of a muscle is determined mainly by its cross-sectional area. The biggest muscle in the human body is the quads. So, the strongest muscles of the human body are the quads. This is just another reason why sumo is easier. Sumo sifts the intensity to the stronger muscles of the body (quads).
      We make arguments based on the human nature. There will always be exceptions

    You are misrepresenting work done with peak power out put, over the rep do you need to do more work in conventional, of course you do. Does that mean that it allows you to have a higher peak output and therefore lift more weight? You’re comparing apples to oranges. It’s like arguing that one sprinting style is cheating and one isn’t cause one athlete is less tired at the end of the race, if the athlete that was more tired at the end of the race tried the other technique and cut a tenth of a second of his time is he now cheating because he used less energy?

    • @YiannisChristoulas
      @YiannisChristoulas  ปีที่แล้ว

      Work is definitely an aspect that should be considered in any type of activity, even 100m sprints, if you want to have an actual analysis of all the components that contribute to the movement. I Agree that other aspects (like the fact that sumo uses more the quads, quads are the biggest muscles, cross-sectional area of a muscle is the most important aspect to muscle strength, therefore using the quads more against using more the lower back would mean… 😊), are more appropriate to explain why the sumo is a lot easier than the conventional.
      However, this is not a video with a breakdown analysis of every reason that proves sumo is easier. It’s just a response to the line “no actual evidence”. So these are some pretty solid evidence, the rest of the debate is only for people that either don’t have an academic background in biomechanics or are sworn defenders of the sumo just because..
      However there are also long term effects that I’m sure anyone can understand. So Two questions for you:
      1) Wouldn’t less work allow me to accumulate higher training volume during a given training period?
      2) Isn’t volume the most crucial training variable to increase maximal strength? If it’s easier to do 10 reps of sumo than conventional, wouldn’t I be able to train more and increase faster my maximal strength?

      I think you need to rethink what you wrote here. The Rate of Perceived Exertion (RPE) is a way to rate how hard you feel an exercise. In his video Jeff clearly said that he has a lower RPE with sumo and for this reason he lifts more to have the same RPE with conventional. But this is exactly the point. If on the same weight you have different RPE then it means the one is easier that the other. That’s the whole point of the debate. I don’t know why he added that to his video because it’s exactly like saying that “yes sumo is easier indeed”. And of course you can’t say what he said… it’s like saying “close grip bench press isn’t harder than wide grip because I lift more repetitions on the close grip and make it equal” 🤦‍♂️ The whole debate is if you can lift the same weight easier with sumo than with conventional, didn’t Jeff admit that with what he said there?

    According to "basic physics" work done onto the barbell is different than work done by your body. You can model the human body as a kinematic chain consisting of several rotating joints. The work done by a rotating joint is equal to joint torque multiplied by joint's angular displacement. You calculate the work done by each joint during the entire motion. This is the work done by your body during the entire motion. I think you can also look at the calories burned in one rep as well.
    So yes, it is true that Work = Force * Distance, that does give the work done onto the barbell, but that is not equal to the work done by your body which is either sum of (joint torque * joint angle) or calories burned. If sumo deadlift is easier, then given the same weight as conventional deadlift, the same person's body would end up doing less work.
    Due to different individuals' biomechanics, they would most certainly have different joint torques / joint angles even if given same weight for the barbell. So overall, I think the argument "less force*distance in sumo" isn't relevant in determining whether sumo is easier or not.

      @YiannisChristoulas  ปีที่แล้ว

      People that are biased in favor of sumo always write comments with words like "your calculations" and "people have different joint torques/angles".
      First of let's start by repeating that these are not my calculations. This is the primary way that work is calculated by an entire scientific field devoted to analyzing the human body's movement. It's called the science of Biomechanics. You can open the Essentials, 4th edition, page 28 and see exactly what I presented here. So my first point here is that you are not arguing with me but more with the preferred way to calculate work in the science of Biomechanic. So first point is that these are not "my calculation."
      But let's see why they do that. Isn't it also true that our body moves in angles and not in a linear way? Yes, our bodies move in angles. But anyone who can answer the question that 1+1=2 can also understand that as long as work done onto the barbell increases, so does the angular work done by our bodies. So even if their not equal, and let's say 100kg onto the barbell are 400joules on the barbell and 300 joules for the body, I assume that you can understand that if you increase the joules needed onto the barbell, then you increase also the joules required by the body too.
      In general, it is almost impossible to measure the actual angular movement of the human body accurately. Even the best tech currently can only do it partially for many reasons. For this reason, and due to the direct relationship between work done onto the object and the work exerted by the body, measuring work with the method they propose (and I presented in this video) is 100% valid.
      It is meaningless to argue that work done is not the same between body and object when they have a linear correlation (one increases, the other increases too), and there is no accurate way to calculate the latter.
      The other big argument from sworn soldiers to defend sumo, is that every human has different angles and torques. Yes, of course, they have, but how do you know that between two athletes of the same height, these differences are adequate to produce meaningful changes? How can you possibly measure something like that when scientists can not accurately do it even in a lab? The answer is you can't. I highly doubt that the magnitude of these differences could have any meaningful effect on people of the same size.
      But even in that case, any angular system will work with less angular distances in less linear distance (overall distance). Isn't that obvious too? I think you are either blind by your biased or didn't though about this a all, and you just wrote a comment from the top of your head (that I now I've now spent 10 minutes answering).If sumo travels less distance, any type of angular system will work with less angular displacement within that distance in comparison to a larger distance.
      You are doing the same things that I tried to debunk in this video. You are making assumptions, and based on your assumptions, you infer conclusions. But if you don't, you can probably answer the following questions.
      1) Doesn't angular work exerted by our bodies increase as the work done onto the barbell increases?
      2) Doesn't the overall distance of the movement affect the angular displacement of an angular system moving within that distance?
      3) Do you have proof that the differences in the angles/torques between athletes of the same size are adequate to significantly affect the force applied on the barbell? Is it just an assumption that you like to believe?
      4) If the method I presented here is not correct. How do you think they calculate work done in sports? Can you show us examples, articles, or anything suggesting that there is another, better practice to do so?

      My background is robotics and I just happen to work out. I also personally prefer conventional deadlift but I'm not convinced it's more difficult than sumo.
      1) There is no generalized linear relationship between angular work by the joints of any kinematic chain (such as the human body) and the work done onto whatever the end effector is carrying (such as a barbell). There are specific conditions in which there is a linear relationship between work done on end effector and work done by the joints. If the joints are constrained to have the exact same angular displacements, and both the joint torques and end effector mass are increased by the same proportion. This condition is satisified if the exact same movement (same joints, same range of motion on each joint) is performed but weight is increased. This condition is not satisfied if different movements are involved, such as between sumo deadlift and conventional deadlift.
      2 ) There is no generalized linear relationship between angular displacements of joints of a kinematic chain and the trajectory of the end effector. For example, I can hold a dumbell and rotate my shoulder / elbow joints such that while my arm is moving, the dumbell is stationary. Overall, the relationship between joint angles / joint work and end effector displacement / end effector work is governed by forward / inverse kinematics, and not the trajectory of the end effector.
      3) This just math / forward kinematics. End effector force is a function of joint torques, joint angles, and kinematic chain configuration. You change the end effector force, by changing these 3 parameters, whether the kinematic chain is a robot manipulator or a human body. If you apply more torque at a joint, there will be more force at the end effector, and vice versa: if more force is applied at an end effector, the joints need to apply more torque to keep the end effector stationary. For example, when holding a dumbell in front you with your arm full extended, the dumbell is applying a force on the end effector (your hand), a heavier dumbell will apply a greater force. This also applies a torque to your shoulder joint. To keep the dumbell stationary, there must be no rotation on your shoulder joint so it must apply a torque as well. If there is no movement of the dumbell, the torque applied by your shoulder is equal (but opposite direction) to the torque it's receiving from holding the dumbell in that manner.
      4) The method you described calculates work done onto the barbell, if that's what you're looking for then it's correct, but it needs to make a distinction between that and work done by your body; the physics explaining work done by a kinematic chain are the same wether its a robot manipulator or a human body,. I don't know what they do to calculate work in sports because its not my area of expertise.
      Some other comments:
      "Yes, of course, they have, but how do you know that between two athletes of the same height, these differences are adequate to produce meaningful changes? How can you possibly measure something like that when scientists can not accurately do it even in a lab? The answer is you can't."
      > Then perhaps I don't think you can conclusively say which one is easier or harder based on these methods alone. In order to make a conclusive determination, other methods should be used in addition to calculation of work, such as but not limited to:
      - calories burned per complete rep at a given weight
      - impact on subsequent exercises after performing sumo or conventional deadlift
      - muscle activation measurements using electromyography (tho I'm not an expert and I'm not educated in the use / interpretation of data from this testing)
      "But even in that case, any angular system will work with less angular distances in less linear distance (overall distance). Isn't that obvious too? " and "If sumo travels less distance, any type of angular system will work with less angular displacement within that distance in comparison to a larger distance."
      > See my response to #1 and #2. Just because angular displacements in a kinematic chain are greater, doesn't always mean the end effector will have a longer path. It's actually not obvious. Forward and inverse kinematics often exhibit nonlinear behaviour and can at times be unintuitive.

      I don't think you understood my 3 first questions. On the fourth I understand that is not your field and you don't know. However, this is probably why you struggle with this.
      1) On my first question, I simply ask if, on similar movements increasing work on the object translates to increased work on the body. You got into extreme examples to present occasions where maybe there is not a direct relationship. But here we are talking about a very similar lifts. If I need 400 joules to lift the barbell and 500 joules were exerted from my body, then if I put 500 joules on the barbell, then I'll also have put more joules with my body. Isn't that proof that there is a direct relationship between these two? It doesn't get more simple than that.
      2) In question two, you try to convince prove again a point with completely different movements. So let me ask it this way, when will your body exert more joules if you lift 100kg or 150kg. The answer is on the second, as the work demanded lifting the barbell. Increase everything increases too. Sumo and conventional are not that different to suggest that the change in angle function can cover up a difference of that size.
      3)and on the third one, I didn't ask you how angle asymmetries affect the system. I asked you if you have evidence that these asymmetries/differences between athletes of the same size, can be adequate to provide meaningful changes.
      Most importantly. this video aimed in presenting some and all the factors that contribute in this equation. Did you notice that on the video? "Here I'll present some science-proven factors" not all. I never said that work done is the only component that contributes in this analysis. I only said that this is one scieence-based crystal clear component, in reaction to "no science-based" that Nippard said.
      In that sense, work demanded in sumo is much less than in conventional, period. Other factors might be favoring the one against the other, but i'd like to see the evidence on that.
      I usually don't respond to comments like this because they never end. No matter how I explain things, the other person will keep finding an extreme example or an exception of the exceptions to prove their point. In reality, I should probably have handed you a biomechanics book to study and then discussed this again with you after you finished it.

      @@YiannisChristoulas Human body is not a machine. What about static work? When lets say someone is in middle of deadlift and holds that position, according to your calculations that means the body is not working thus it will not consume energy. We know thats not true right? Human body works different than a machine.
      You can also lift the barbel up with your arms while doing the downwards deadlift movement so it will keep the barbel in a static position. Does that mean no work is done at that moment only because the barbel is in static position?
      Also he is true in different aspects and you should calm down because I am also a mechanical engineer and his understanding seems far superior than yours.

    idk. I always bashed on sumo because it looked stupid to me. But i actually can't do sumo as easily as conventional. I understand it's probably because I don't train sumo at all, but it feels terrible and I really don't like how it feels when I use it. (it almost feels unsafe).
    lot of people argued for sumo deadlift because it replicates how we should be lifting something off the floor. I've literally never seen anyone including me using sumo deadlift style to lift anything heavy off a floor.
    All in all, I think sumo deadlift is more like wide arm pull up. Wide arm pull up is harder short grip pull up just because it uses less muscles despite less distance moved. It's like bicep curling 45 lb is easier than wrist curling 45 lb despite wrist curling also has less ROM.

    This analysis misses out on a key aspect of lifting heavy weights: you don’t miss a rep because of the total exertion throughout the rep (total work, pointed out here), you miss a rep at the weakest point (between the point of maximal contraction and minimum velocity) when the muscle gives out. It doesn’t matter how much less energy you’re putting into lifting the weight if your muscles aren’t strong enough to produce the necessary contractions. That’s where more complex calculations like Nippard’s or Greg Nuckols’ come in.
    That said, I consider the two as separate exercises outside of competition settings where both are legal.

    • @YiannisChristoulas
      @YiannisChristoulas  ปีที่แล้ว +2

      I’ll try to explain this the best way I can, although if you found Nippard’s kindergarten ultra-biased calculations complex I’m not sure if you’ll understand this comment.
      1) First let’s say that things are that simple and work doesn’t matter for maximal strength tests. My second argument with the angles presents why there is a clear benefit in the mechanics of the sumo that can significantly effects maximal force. So you commented by saying that half of my arguments didn’t take under consideration maximal force and you ignored that the second one did. It’s like ignoring that lifting from blocks doesn’t make a difference.
      2) Now let’s get a bit more serious. Every single paper that has been done on strength development has proven that more volume results in more strength gains. If you can do on average 2 more reps with the sumo on a 10-rep set, for 20 sets per week, this equals to around 160 reps more volume per month. Isn’t that enough for the sumo lifter to develop much faster strength adaptations than the one that does conventional? Just think about it. With sumo you’ll probably do around 2000 more reps per year while spending the same amount of work. If you’re not a fitness professional I don’t expect you to have thought about this instead of just thinking what work does on a single lift. However I would expect Nuckol to include it in his “complex” calculations. For some reason he didn’t.
      3) Yes these are different movements but our job as fitness professionals is to compare, to understand and to know. If Wide grip pull downs are harder than close grip pull downs I won’t try to argue that they are not, by saying that these are just different movements.
      4) if you saw the intro of the video you probably saw that this is not an in-depth analysis of every reason sumo is easier than conventional. Is only a response to the “no sound evidence” that nippard claimed. So I just made this video to present two undeniable science facts that are easier on the sumo. Just that. In the future I might do one video to explain a lot more reasons why sumo is easier, IF Nippard has the guts or the scientific capacity to ever respond to this video and ask for more 😎

      lifting 100kg by 20cm conventional is easier than lifting 80kg by 20cm with one leg only, even though the amount of joules is smaller, we need to take into consideration the work done by the involved muscles. (Which is the tricky part)

    Wait, so if a shorter athlete lifts the same weight a shorter distance, they aren't taking advantage of their physiology but "cheating". But, regardless of the height lifted, if the taller lifter plants their feet at the exact same width as the shorter lifter its not fair because it's a mechanical disadvantage to them even though it's the exact same barbell, plates, and foot placement? Huh. The deadlift isn't a contest to lift to a specific height. The amount of joules may matter in the course of training and diet and nutrition, but when it comes to the lift itself a lockout is a lockout, the plates are the plates, and height doesn't matter.
