Ilya Shymanovich broke the world record in the men’s 100 breaststroke during the ISL’s fifth playoff match in Eindhoven for the second time in the span of a week, clocking a time of 55.28.

Shymanovich’s time lowers the previous world record of 55.32 he set seven days ago during Playoff Match 3.

When the 27-year-old set the previous record last week, he broke his 11-month-old mark of 55.34, set at the Belarusian SC Championships last December.

Split Comparison

Shymanovich was slightly slower on the front-half than he was last week, but closed over a tenth better in 29.43. On Day 1 of the match, he put up the second-fastest 100 breast relay split ever in 55.00, splitting 25.27/29.73.

2020 BLR Champs 2021 ISL Playoff Match 3 2021 ISL Playoff Match 5
25.88 25.77 25.85
29.46 (55.34) 29.55 (55.32) 29.43 (55.28)


The Belarusian now owns six of the 10-fastest swims ever, and has been sub-56 a total of 13 times.

All-Time Performances, Men’s 100 Breaststroke (SCM)

  1. Ilya Shymanovich (BLR), 55.28 – 2021 ISL Playoffs Match 5
  2. Ilya Shymanovich (BLR), 55.32 – 2021 ISL Playoffs Match 3
  3. Ilya Shymanovich (BLR), 55.34 – 2020 Belarusian Championships
  4. Adam Peaty (GBR), 55.41 – 2020 ISL Final
  5. Ilya Shymanovich (BLR), 55.45 – 2021 European Championships
  6. Adam Peaty (GBR) / Ilya Shymanovich (BLR), 55.49 – 2020 ISL Semi-Final 1/ 2020 ISL Final
  7. Cameron van der Burgh (RSA), 55.61 – 2009 FINA World Cup
  8. Ilya Shymanovich (BLR) / Nicolo Martinenghi (ITA), 55.63 – 2021 ISL Match 8 / 2021 European Championships

Cameron van der Burgh set the world record in the event at 55.61 in November 2009, and it stood for 11 years until Adam Peaty took it down last year in the ISL semi-finals. After no one broke the mark for 11 years, the record has now been lowered five different times over the span of one year.

World Record Progression, Men’s 100 Breaststroke (SCM)*

*Since January 1, 2000

Just like they did in yesterday’s 50 breast, Shymanovich and Energy Standard teammate Felipe Lima jackpotted the entire field in the event to score the maximum 37 points for the club.

Shymanovich is now a perfect six-for-six in the men’s 100 breast during the ISL season, cracking 56 seconds in five of those swims. He’s also won the 50 and 200 breast five times apiece.

Peaty would need to be in form and tapered to compete with him and even then would probably lose.

What is the fastest ever 100 BR relay split?

For short course? Peaty’s 54.84 from last ISL season.

I have not been paying attention, is that a dolphin kick on his stroke?

Reply to  Horninco

So a lot of people here will point to the narrow kick he takes on every stroke but really the only illegal part of his races that’s actually against the rules is his tendency to take a dolphin kick into the wall. From what I can tell he’s largely stopped doing that but his nickname from 2020 has stuck despite his never being disqualified. Which sucks because he wasn’t close to being the only offender but you don’t see guys like Morozov, Sacki or Martinenghi being defined by their questionable racing habits like Shymanovich has.

People still rip van der Burgh to shreds every time he’s mentioned.

Because he admitted he intentionally did it. Everyone else, including Katijima, says they didn’t do anything wrong/weren’t caught.

When Peatty gets down to business, he’s going to eat this guy up and spit him out (so to speak)… in gentler terms, Peatty will beat SHYMANOVICH IN ANY SOON-TO-COME HEAD-TO-HEAD COMPETITIONS…BANK ON IT…. (FAMOUS LAST WORDS)….HEHEH….

Race video?

Saw a clip of it on YouTube and he had a bit of a beard going. If he wasn’t shaved, he probably wasn’t full tapered either. I’d expect a 54 from him in the final, assuming ES makes it through.

Looks like Shymanovich is the Peaty of SC breaststroke. His pullouts and starts aren’t even that crazy–he carries his speed off the wall so well and gets up and stroking as effectively as possible. At this point, I don’t think Peaty can quite hang with him in the short pool, and I’d love to see what he could do in SCY (albeit completely pointless)…maybe 48-something?

Agree, though he’s very quick in and out of the wall on his turns. The only “point” of a SCY swim is to get the young Americans to realize what “fast” really is.

I mean, if it’s legal, which it is, more power to him for figuring out a way to be fastest ever, which he is in the event. Guarantee when we fast forward a few years, everyone of a similar body type will be doing exactly the same thing. Breast has probably gone through more technical innovations over the last 40 years than any stroke. Check out videos of every Olympics since ’72 and you’ll see how much it’s changed. Hannis has been doing it for years.

The thing is, if everyone does follow suit and this becomes the new breast, then all the breast records will get demolished very quickly, and history will likely show that Shymanovich wasn’t that good: he was just the first to game the system.

You can say the same thing about Chet “The Jet” Jastremski, Barrowman (his 200 breast record stood for 10 years), Catie Ball, a host of other technical innovators, and eventually Peaty (the gap has clearly narrowed). For a long time, the head couldn’t go under the surface of the water, no one was recovering with hands breaking the surface, and there was no dolphin kick, and when there was, it was simultaneous with the pulldown. The dolphin action is probably the least radical change in the history of radical changes in breastroke.

The world record holder isn’t that good? Do you ever hear yourself?

Reply to  FluidG

It’s because he’s using a technique that is, at best, flirting with the rules.

I think super suits are a good comparison. A bunch of people broke world records when super suits were first introduced. Is it because they were actually better than the old records, or because they were using soemthing that no one else had used yet? Almost every super suit world record was quickly broken again by someone else wearing a super suit.

So was the first person to break a WR wearing a super suit actually that amazing? Or was it just that they were the first to use something that technically wasn’t against the rules but clearly gave them a functional advantage?
