    Extremely informative and helpful! @theraceclub The only thing I didn't really understand was why pigeon-toed feet generate more propulsion during the kick than having the feet pointed straight back. The video said that "if they're pointing inward, they're traversing the stream at right angles--they're gonna get more propulsion that way than if they're pointing straight back". I believe it, but I don't understand why right angles would generate more propulsion than the feet being straight back. (I'm a younger swim coach, 22, trying to learn as much as I can about efficiency in the sport to best coach my athletes. Just trying to learn!)

    • @theraceclub
      @theraceclub  4 роки тому +6

      Hi Max! Most don't understand this principal, but it has to do with the motion of the surface area of the top of the foot (on the dolphin down kick) relative to the slip stream of water moving behind the swimmer. If the foot moves with the stream, it generates less propulsion than if it moves perpendicular to the stream. You can test this in the water by kicking dolphin or freestyle with toes pointed straight back, then with the feet pigeon toed. You will feel more propulsion in the latter position.

    Keeping the toes together seems to create a bigger surface with which she propels herself vs letting water slip through. As we see with deep divers a mono fin requires less effort and better speed over two fins.

    This video has done more to improve my kicking than all the others I have watched combined, and I have watched a lot of them. The key things I took away from this was going pigeon toed and pronating my ankles. I always used to kick with my feet/toes pointed out straight behind me. For years, it took me about 57 seconds to get the length of the pool with flutter kick. I tole you I was bad. In the months since I have seen this, I am down to about 1:10 for a full lap in a 25 yard pool. There may be help for me yet... I did figure out how important the up kick was the first time I put on the stubby fins. Action/reaction.... I have been putting more effort into the up kick.

    돌핀킥은 뉘앙스 즉 작은 차이로 잘나가고 안나가고가 결정되는 수영에서 중요한 동작.
    1. 적당한 상체 바운스(가슴누르기). 3:27 지나치게 물결처럼 물타거나 경직되면 ㄴㄴ. 마커스는 지금 자기가하는 돌핀킥이 제일 에너지효율적으로도 속도 면으로도 베스트 킥임
    2. 발목 유연성 -> 추진력 6:05 발목유연성이좋으면 켈시처럼 자연스럽게 발끝이 안쪽을향하는데 그걸 pigoen toe라 함. . 발을 그저 뒤를 향하게 즉 1자로 하면 추진력이 덜하게 됨. 마커스 아직 유연성 더길러야함 인대스트레칭해라.
    3. 적당한 다리각도. 8:12 루카의 경우엔 80도정도로 꺾는데 그게 속도 줄이는 주범임. 60-70도가 좋을듯. 루카랑 마커스랑 속도비슷한데 에너지효율면은 마커스가 더나음

    Excelent video! Thanks for sharing! First variable of speed is the kick, I agree. What about aditional propulsion power of ondulation? A snake or an eel has no kick whatsoever. They move nevertheless surprisingly fast in water.

    • @theraceclub
      @theraceclub  2 роки тому

      Undulation helps in two respects. It enables the swimmer to press the tops of the feet downward through the vortices longer and farther, maximizing the propulsion from the down kick. Second, it enable the swimmer to generate more propulsion from the subsequent up kick. Snakes and Eels have much better drag coefficients than humans do.

    • @theraceclub

      The monofin changes everything. With large surface area kicking in both directions is important and to up kick the upper body and arms must move in the water. Even fins change the dynamics of the dolphin kick. That it is important to train a lot without fins.

    Keep viewing this one.... So, another question, this is all about the underwater off the wall kick. Are there any or much differences in flex angles at the knee when you are on top of the water? I would guess the flex angles might be less because your feet would come out of the water and you would be kicking air on both up stroke and down stroke....

    • @theraceclub
      @theraceclub  5 років тому

      We have found the angle of flexion in butterfly is usually similar to what is used on underwater dolphin kicking in streamline. Most of the time there is too much knee flexion. With flexible ankles 60 degrees seems to be about the right amount. While swimming on the surface, the foot must come out of the water on knee flexion or one cannot generate enough propulsion. Same with kicking on the surface. In lane 3 you can find a great video on what too much and too little knee flexion does to the kicking speed.

      @theraceclub  4 роки тому +1

      Dolphin kicking does require having good lumbar flexibility, but not as much as in breaststroke. Just try not to overbend the knees (60-70 degrees maximum) and flex your hip to about 20-30 degrees after the down kick. Ankle flexibility is key to fast dolphin kicking.

    Garry we always talk about streamline and sometimes to use word hyper streamline but I have seen swimmers like Joseph schooling and the Hungary swimmer cseh laszlo, they usually come to much above the water during breathing which should create drag but eventually they are amongst best swimmers of world..What makes them win going against the physics??

    • @theraceclub
      @theraceclub  5 років тому +7

      Thank you for your question, and for watching our content! When referring to hyper-streamline vs "normal" streamline we're referring to what the swimmer is doing off of the blocks and off of the turns. We want to see the chin tucked and the arms on top of the head in the hyper-streamline position, which we have tested and shown is less drag.
      When looking at the 100 fly from Rio where Joseph and Laszlo are competing, they do breath slightly higher than some others, but not to the extent where they are lifting so high they're increasing drag and going against physics. They both also do a phenomenal job of using the physics of the coupling motions by throwing their head and hands aggressively into the water timed perfectly with the second kick.
      They've found the sweet spot of getting as much power and propulsion as possible, while reducing drag as much as possible at the same time. There is always a trade-off, but it seems they do a great job with it. Thanks again, Coach Devin

    • @theraceclub
      @theraceclub  5 років тому +1

      I agree with Devin and will add that both have unusual butterfly techniques. Joseph's is unusual in that he uses a late breath technique, lowering frontal drag by keeping his head down longer. He does not elevate the shoulders as much as Lazlo, who uses a very vertical, high arm recovery and throws the head, shoulders and arms aggressively down to augment his second down kick. HIs first down kick is almost non-existent...so in effect he relies on a huge surge from his second down kick and gets it. Were it not for a horrible finish in Rio, Lazlo would have been standing alone on the silver medal podium.

    Why would you pull the feet apart on the back kick? It should be used for additional propulsion.

    • @theraceclub

      The upkick? You want to try to keep them together but it's harder to do than during the down kick... more important is the point of the toes.

  • @snowpants2212

    Marcus looks to have solid ankle flexibility and use pigeon-toeing to accentuate it. He also seems to be pointing his toes straight back on the upkick. What I'm seeing is a lack of shoulder flexibility, which is forcing his arms and upper torso to angle downward at the start of each kick. This takes his upper body out of alignment and forces his lower legs up outside of his body line. It also deprives him of a full upper-body counterbalance to his downkick. Compare Dressel, whose arms actually press up a bit to counterbalance and provide leverage during the downkick.

    • @theraceclub
      @theraceclub  Рік тому +1

      Good observations! Ideally, we want to see the hands move 6-8 inches but equally above and below the line of motion. Marcus doesn't get above the line of motion well enough at the end of the down kick. He doesn't peak very high but his troughs are also high which keeps his average speed up there. Mechanically very efficient.

    What is the body vortex?

    • @theraceclub
      @theraceclub  5 місяців тому

      The body vortex is the slipstream that forms behind the swimmer as it moves through the water. The feet generate propulsion by playing off of the two votices caused by the body moving forward and the legs and feet moving up and down.

    I think you want your toes pointed inward on the down kick and slightly outward on the up kick. This is what Dressel does. The gluts can’t fire when the toes are pointed in.

    • @theraceclub
      @theraceclub  3 роки тому +1

      The feet are more or less straight back on the up kick and inverted (pigeon toed) on the down kick to maximize propulsion.

    Oh, another domino cascade in my brain..... There is considerably more knee flex used in the dolphin kick, and probably the whip kick in breast stroke, than there is in freestyle. I would guess that back stroke flutter kick may have a bit more. I would guess the reason is that fly and breast stroke are more body wave/3 dimensional strokes, and the freestyle and back are more stream lined. I never considered getting out of the body vortex as being able to supply more thrust, but that seems obvious now. Get far enough beyond the vortex to generate more thrust, but keep it within a certain range so extra drag doesn't trump the extra thrust. Heel and calf are more stream lined than the thighs too... So, are velocimeter videos on the other kicks in the works????

    You state in your video that increasing knee bend angle is detrimental to speed. However, when you observe swimmers such as Phelps or Dressel, you will notice approximately a 90 degree knee bend in spite of their world-class ankle flexibility. Do you have any idea why this may be?

    • @theraceclub
      @theraceclub  2 місяці тому

      Actually, neither swimmer is or was near 90 degrees of knee bend on dolphin kick. The acceptable range is from 50 degrees to about 75 degrees. Beyond that, too much deceleration. Caeleb is around 70 degrees maximum and Phelps was closer to 60 degrees maximum knee bend.

  • @robohippy
    @robohippy 5 років тому

    I never thought about intentionally pronating my feet as I kick. Makes sense. My feet don't hyper extend when I point my toes on the down/forward kick like the Olympic caliber swimmers feet do. I have been trying work on my kick since it is the weakest part of my swim. By pronating, you get a better push angle on your oar blade/foot since the foot naturally slopes from high on big toe side to low on little toe side. Tried the pronating yesterday at work out and it took a few kicks per pool length at medium kicking power compared to kicks/length at full power. Now to see if I can learn to do it without thinking..... My preferred stroke is the over arm side stroke because no one else swims it at anything near competition level. 68 years old.....

      @@theraceclub Pronating my feet is becoming habit now. Never could do the old frog kick for breast stroke, or the newer whip kick that they now use. After getting one knee replaced the doctor told me not to do the breast stroke, which was fine since I couldn't do the kick before replacement. I have adopted the 70 degree flex angle for my scissor kick on my over arm side stroke. I was never sure how much bend I should use before drag was more than the added thrust I would get. I have turned the scissor kick into more of a whip kick too, keeping a more slim/hydrodynamic profile then the old school 90 degree open and scissor kick closed. I did show this video to a couple of coaches at my pool. Love the new gadgets to measure every thing... Side stroke rules, breast stroke drools..... Old school over arm side stroke, only record is 1:02.5 for 100 yards, set in 1895.....

      O I guess I should add that this pronation thing is some thing that every one knows about, but no one really teaches or explains it...

      To work on pronation you should do basic flexibility stretching every day. I either sit on my feet with my shin/top of the foot on the ground or lay on the ground on my back and put my feet under a chair or another object that flexes them downward. Bands can help too and even just rolling your ankles and moving your feet up and down will improve flexibility.

    • @theraceclub

  • @robohippy
    @robohippy 4 роки тому

    Well, a couple more comments.... With Kelsi, I am wondering why she has an advantage with her kick being more knock kneed and pigeon toed. I tend to think in aviation terms. There are 2 types of drag, parasitic, which is resistance/friction due to moving anything through the air, and induced drag, which is what you are calling the vortex here, or all those eddies left in the wake. The vortex, directly behind the body is fairly significant. There is another vortex that in aviation, I refer to as the slip stream, which here would be the water that flows along the sides of your body, and the eddies would be smaller than the main ones directly behind. So, her down kick is in the slip stream and the water is not as disturbed as the water directly behind.
    Another one I am trying to figure out with the dolphin kick. A lot of people drill by kicking laps on their back. When underwater, no matter if I am on my back, side, or front, my cadence and amplitude are pretty much the same unless I want to exaggerate. When on my back and doing the dolphin kick, no matter how much I try, I always am at a shallower amplitude and faster cadence. Is there any particular benefit to practicing while doing the dolphin kick on your back, or is it just for ease of breathing purposes so you don't have to use a snorkel?

    • @theraceclub
      @theraceclub  4 роки тому

      In water, there are 3 types of frontal drag and at elite swimmer's race speed (over 2 m/sec) they are all important. Pressure drag (what you refer to causing the vortices) accounts for about 50% of the total drag. The other 50 percent is divided between surface (wave) drag and friction. As swimmers, we need to be mindful of all three.
      Regarding dolphin kick, it is a complex subject. You are faster dolphin kicking on your back because the weaker down kick becomes much more powerful by kicking against the bigger vortex (and help from gravity) to generate more propulsion from the weak side. It is more compliant with the law of inertia (more efficient) on your back. Besides that, it is nice to be able to grab a breath whenever you want to without lifting your head up.

    • @robohippy
      @robohippy 4 роки тому

      @@theraceclub I had to ponder this one for a bit. At first I thought this was geared to the push off the wall or the start when the swimmer is under water. In theory, bpdy position, right side up, sideways, or up side down wouldn't make any difference because water pressure would be pretty much identical no matter which direction you are facing. I guess surface tension/making a bow wave,, when you are on top of the water would be an added drag element. Not sure about dolphin kick on my back being stronger, at least not for me, which is probably 90% mental and 10% in my head (Yogi Berra). I just can't seem to get the amplitude on my back that I get on my tummy...

    2. Agin at 7:18 he says the angle 80 degrees. It is clearly not 80 degrees.
    3. For the third time at 7:50 he says his knees are at 80-85 degrees. At this point idek maybe he is measuring the temperature of the water or something.
    4. At 8:23 he says to get his legs to 60-70 degrees. That would be pointing the same way as his head if we where drawing it the same way as we had in the past. I genuinely have no idea where they get these numbers.
    5. Turn subtitles on and watch 8:27 ???

      The angles we are referring to are from a straight line backward from the upper legs, not from the thighs to the lower legs. Just subtract our angles from 180 degrees and you will get the angle you are looking at. BTW, the reason we do this is so that the angle increases with increasing knee bend. That is less confusing to most people.
