Myrtha Pools Says Tests Showed “Zero Hint” Of Current Problem In Rio

After SwimSwam contributor Barry Revzin published a statistical analysis suggesting there may have been a current in the Rio Olympic pool, the president of Myrtha pools passed along video footage of tests that show “zero hint” of a problem.

Revzin’s analysis is here; he compares splits heading each direction in the pool for all 8 lanes, finding a greater disparity in the 2016 Olympic numbers than those from the 2015 World Championships, 2015 U.S. Nationals and 2016 U.S. Olympic Trials.

We reached out to Myrtha, and president Trevor Tiffany provided video footage of tests done before and during the meet.

“All I can say is we tested the pool both before the event and after day 3 of the swimming with zero hint of a problem,” he said.

You can view the two tests here and here. Neither appears to show any movement of the test float.

Tiffany also said the analysis showing faster times for certain lanes could have an alternate explanation:

“The fact that certain swimmers swam faster one way than the other and that this differed depending on which side of the pool they swam can perhaps be explained simply by which side they breathe,” he said. “Normally they would be faster when facing their competitors and if this were the case, then their times would clearly be faster in different directions when comparing their swims in lanes 1 & 8.

“We welcome further serious research as we all want the same result. Fast swimming and fair competition.”

Ah, the Rowdy Gaines explanation….nice

Someone (not me because I’m too lazy) check the swimmers that had big differences in their splits and which sides they breathed to. Shouldn’t really be a crazy thing to investigate.

I mean they’re not wrong. I’m a sprinter, but on the rare occasion I swim distance, I’ll swim faster when I can see someone to race on the side I breathe

Barry Revzin
The breathing argument doesn’t really work for at least three reasons. In no particular order: First, it simply doesn’t explain the 50s. Everyone is going all out, people breathe sparingly if ever, there’s really not going to be an effect there. If the breathing explains the distance events, something else would have to explain the 50s. Secondly, the effect I see directionally, if it was caused by swimmers seeing their competitors and reacting to them, could only happen if everybody breathed to their left exclusively. Just briefly looking through videos, it seems like most people breathe either to their right or bilaterally. Thirdly, if swimmers reacted this way, the effect wouldn’t be localized to Rio – it would appear in… Read more »

What brand were the pools in the other meets?

Would be nice to see a comparison of the float’s locations in the videos overlayed with the suspected current/drift location. It’s possible that some lanes experienced a current, other did not. Isn’t that the point? Seems like showing a float in one lane is not substantial QC.

What about ledecky then? Was she faster when she was breathing to side where she could see zero of her competition?

No, she could definitely see them going the other way.
