Allow me to point out a couple of things: 1. He's Romanian, not Italian so it's pronounced "Popovich" 2. Head position - It is not an "extreme version" of his breathing. When he is going at full speed, BOTH goggles come out of the water and that angle actually increases. Why do you think his head is at that angle on the breath? Because it is literally as you said; water is 800 times the resistance. He has half his body surfing over the water while maintaining a powerful kick which keeps his hips up ( he has incredibly flexible hips). It is entirely intentional. He is swimming higher in the water. 3. Rotation - you would be absolutely correct that the flatter position is slower if he wasn't actually getting a lot of his torso completely out of the water. 4. Race analysis - *46.86, not 49.86... EVERYONE will probably disagree with me on this but this is my hot take: gaining 25 lbs of muscle might actually hurt him. Yes, he will be more explosive. Yes, his start will improve. But the trade off: volume(he will be larger/wider causing a slight increase in drag) and buoyancy(increase in density = lower position in water, increasing drag further). He has great strength, but his lightness finesse, flexibility, and technique is what sets him apart. His ability to stay HIGHER in the water makes him so fast.
Every time I hear about fixing angles or body position that should look perfectly - hurt my ears a bit. Every correction having a price, it never just an improvement on a hight level. Changing angles, body positions, gaining weights. Who knows - maybe his head position helps him to relax more during the stroke. Putting more weight for David should be a mistake in my opinion. More power> more speed>more resistance. That’s why 95% of 50m sprinters drop their speed on the races.
@@djinjis it's not necessarily in long wingspan, almost everything is about technique, look for example Gustavo Borges, brazilian gorila, he has extraordinary wingspan of 221 cm, and he couldn't swim sub 48, as Alex Popov in one podcast said its more mental than physical. He maintains speed and efficiency better then anyone else when it matters most. The end of the race, when everyone is feeling the pain. It's not that he is accelerating. It's that everyone else has hit a wall. His wall is after the actual wall. Sprinting is not about being the fastest. It's about slowing down the least. Speed maintenance. For David, it's about efficient producrion of world class speed. His feel for the water at such speeds is the best in the world.
As an ex competitive swimmer, his technique is beautiful and virtually flawless. He has focused on efficiency and then added the power. His technique allows him to utilise his ridiculously high power to weight ratio. Simply a very clever freak of nature.
Former D1 swimmer and current coach here. He is efficient but he gallops. You can see in the footage how his bodyline changes a lot like pointed because he lifts his head to breathe. Pair this with an uneven pace on his arms and you get a gallop/bounce that just wastes your energy.
In the meantime we are witnessing the new world record holder, I think that we have to teach the other how to swimm like him. I have read a lot of articles and watched too many videos on correcting him. I don’t understand why? With this technique, he swam the best time ever!!! The lesson that I think that all of us have to learn from what happened with this record is that EVERYONE MUST FIND WHAT IS COMFORTABLE FOR THEM. So even if you say that you have to learn from him, than you are actually wrong. He has found the best way for himself. Your job is to find your best way that gives you the best result. Read, learn, ask, but in the end, you have to find the best way that adjust you and only you.
@George George If you think that the pronounced lope don’t make them different from each other than I think that you completely wrong. Swimming is a sport that is veryy, very much about details. Not that other sports are not, but in swimming there is no luck. Water, doesn’t forgive you even for the smallest mistake possible! There are waay waaayy to many things to take into consideration! My opinion is that to do what he did, you have to find the best of yourself for the reason that you in a way have said. They all do the same thing 🤷🏽♂️. In fact, it just looks like they do the same thing but not. If all of the swimmers you have mentioned do the same thing than why they don’t have the same times? The same trophies? The same achievements?
The tip about his hands entering the water at an angle is swimming gold!!! Tried that in today's workout, my pull felt about a foot longer... Great insight!!
Great video as always! now as I´m sure we will hear very often from David in the next 10 years or more, please note that the correct spelling of his name is with a mute "i" at the end. Kind of "popo which"! Go David!
Another great detailed breakdown Fares. To me Popovici seems to have a slight fly type motion in his stroke where his powerful leg kick combined with incredible hold of the water allows him to almost climb over the water for fractions of a second.
Interesting break down. However, you still need to become familiar with the Gallop style of freestyle, which is also called by some 'Hybrid' style of freestyle. Hybrid being a combination between shoulder driven and hip driven freestyle. I will continue to maintain that hips can not drive anything, but that is another matter.... Anyway, this gallop style seems to go back to at least Mark Spitz, though his version was very coarse. Matt Biondi did it far better, and the modern swimmers do it still better. It does involve that slight upper body twisting that you pointed out and a slight porpoising while swimming. Arms come over the top slightly higher so you can drive your catch/recover forward and down for a bit more acceleration. The cadence is not even, but a quick 1, 2, then a slight pause, then repeat. Even distance swimmers like Sun Yang use it. All of the men use it, and a few women like Katie Ledecky use it. The things he does that do not fit 'classic' freestyle are due to this method of freestyle, and they contribute to faster speeds.
It really is going to be interesting to see how we develops. He's still quite young and skinny, when he begins to pack on the muscle and become more explosive especially on his starts and turns we will be in for quite a treat!
Nice analysis. As a former swimmer I agree I appreciate your effort. One thing I didn't see which I would say I very important is how he keeps his hands under the water and moves them and specially his fingers.
I’m both a swimmer and a fan of human movement (in a nerd kind of way - hence my presence in this comment section). I encourage you to look up GOATA. I actually disagree with the idea that his spine going off line, is a bad thing. All elite movement amongst mammals begins with the spine as an engine. Fish literally ONLY use their center to flap side to side and thus move forwards. I actually think David is onto something here which others may have historically overlooked - hence his talent
Nothing new, but a good review of technique specifics that Popovici does near perfectly. And as long as specifics are the subject here: the hands are in the water IN FRONT of the shoulders not because "it's more efficient", but because placing them elsewhere creates a lateral vector in a sport where we want only head-to-foot vectors. The lateral vector will 1) use energy to create 2) not contribute to forward motion 3) need an equal and opposite vector to keep from moving laterally (more wasted energy).
I am so proud that I came also from this country. Unfortunately for me I was not so privileged to have in my town a Swimmingpool. Yes, no one. And even are more than 30 years ago from our dictator was go… are still today very much town without a swimming pool for people and children to learn to swim. Also for parents today are very expensive to bring the own children to the swimming pool. I think it ist very interesting to go to meet him and spoke with him about his hard work also with the trainer’s. I learn free style Fares very late in my life and also that you give in 2019 the opportunity to see your Myswimpro videos for free. You make a 👏🏻 Job thank you 🙏
Hey! Great video analysis, however, your interpretation on David's first 50m might be inaccurate - in one of interviews he explained he is not pushing first 50 so hard on purpose... And this is his secret to be so incredibly fast on second 50. He told he was working A LOT on his "easy speed" meaning he is able to save the energy for the second 50. While others try to keep the pace after a turn, David starts showing what he is really capable of. "Losing" a start and first 15m meters is not an accident, but acting on purpose. I am not saying he is a swimming god, however EVERY stroke, every move, every breath and speed is counted and solidly prepared before the race. I would even say that searching for improvements in his first 50m is pointless as this first 50m in fact is his key to blow on the second... :)
'Popovici started swimming at the age of 4, at a doctor's recommendation to correct early stage scoliosis.' Hence Professor Fares hit on the right thing sharp!
I can say you that the core is the part of the body that does all the work. If you finish the swimm and you dont feel tired in the core muscles, than something is wrong. You have to learn how to activate them and NOT focus on keeping them tight.
I do! An adjustment in his start and underwater would put him with the pack as he surfaces. Just that difference would take off at least a half second!
Please clarify about his rotation. In the past, you mentioned about 45 degrees. That looks like more than 45 degrees. A front view may help show his shoulder angle vs the body axis.
I wanna know what is different between early vertical form and front crawl style ? I know both might use high elbow right 😅 please correct me if i am wrong
Your second teaching error is in EVF. EVF does not occur when you are pointing it out, but rather EVF occurs when the biceps are parallel to the water surface and the fingers move ever so slightly downwards, not on purpose, but rather as a result of bending or more correctly "loading up" the entire arm, as this is what is termed "the catch", but nobody sees this because it happens in an instant.
At 7:13, the snaking comment: compare where his 2 shoulders are located when his left arm is at full extension forward. You said his head is snaked incorrectly to the side: WRONG COMMENT. The only way to move the left shoulder forward is to clear the head, this allows the left shoulder to move more forward: gaining speed. Then, when the arm is fully extended, then he weights up the left bicep & left forearm to perform the catch 12 inches ahead of your catch: this equals sooner power.
I observe his legs bending not straighten when he performed kicking .. he bent his knee and the gap between two legs spread seems wider than others but it doesn't bother his speed. How come? It wont affect his gliding as he bent his knee when kicking 😅
I have been trying to improve my freestyle technique for month and today I finally took a video of my swimming and that’s actually terrible 😞 but anyway I will try to do my best
i just curious about that you reveal their technique in swimming , would they feel offended 😂... somemore you visit them directly and make an interview with them. 😅. It is possible you can visit asian swimmer like Singapore one ,Japan one ,China one etc 😆
Rectangles (not squares) drawn at cca 6min do not represent any surface area producing drag or resistance (or any slowdown force inducing) area, really. They do not.
@@luigiturri7193 it's about pronouncing it, not spelling it, the I is silent. If he was Italian it would be like Luigi, but he is not, the I at the end sounds like an h, go listen to a recent interview, where he explains his own name pronunciation.
Absolutely wrong in your analysis. His head moves out of plane so that his left arm extends further forward by pushing his shoulder forward. This is why he is so fast! If his head is as you say, then his shoulder cannot move forward as it rotates about the spine. You are teaching wrong.
according to my calculations .. if I extrapolate the exponential graph of 100m freestyle records then in 6742AD the world record will stand a 5.89s for the 100m freestyle. (however the world will probably end considerabely before that time)

Hi Fares, a general question, please help. Do you relax your core/abdomen muscle or tight them during the strokes? thanks
i think you should not do it, because you gonna distract your self, and it's unnatural
I can say you that the core is the part of the body that does all the work. If you finish the swimm and you dont feel tired in the core muscles, than something is wrong. You have to learn how to activate them and NOT focus on keeping them tight.
im 17 rn , looking at this is mindblowing
Stiuca noastra romaneasca a invins rechinii mondiali❤
Love this analysis. I waited this for months! Do you think if he lead the first 15 m, is he able to keep up in the last 25 m?
I do! An adjustment in his start and underwater would put him with the pack as he surfaces. Just that difference would take off at least a half second!
Do you think his body is different from others? Does it matter to the way one swims?

What app do u use on iPad to make those drawings and edits?
David trains during the cold season in an open pool covered by a giant inflatable balloon. That is the best his country could do for him.
I observe his legs bending not straighten when he performed kicking .. he bent his knee and the gap between two legs spread seems wider than others but it doesn't bother his speed. How come? It wont affect his gliding as he bent his knee when kicking 😅
Your knees will bend naturally when you swim! The kick power isn't originating from his knees, but they are a result of his quick, snappy kick
I have been trying to improve my freestyle technique for month and today I finally took a video of my swimming and that’s actually terrible 😞 but anyway I will try to do my best

left-hand fingers are partly open: loses pulling surface right there...
It's actually recommended to have your fingers relaxed - by doing this, you create a membrane between your fingers and the water and increase the surface area of your pull :)
@@FaresKsebati right-hand fingers are closed: loses effective pulling surface right there! :D
hydrodynamically there is for sure a maximization of the effective drag at some intermediate interdigital separation - - i'd bet no more than a few millimeters - - of course as a function of realized arm speed... but this guy for sure is doing whatever.
