The Kayoko Show: Long-Term Consequences of Agonistic Interactions Between Lobsters, and the Osaka Women's Marathon

by Brett Larner

Back during my time at the Marine Biological Laboratory at Woods Hole, at the urging of Dr. David Bodznick I attended a lecture by the great Harvard University neurobiologist Dr. Edward Kravitz on social interaction and competitive behavior between lobsters, and its underlying biochemistry.  "Aggression is a nearly universal feature of the behavior of social animals," Dr. Kravitz said.  He explained how lobsters have a complex social hierarchy based on individual interactions, how when two lobsters meet for the first time they go through a ritualistic series of increasingly aggressive fight behaviors to establish a winner and a loser.  Once that dichotomy is established it doesn't change.  The winner remembers that it is a winner, the loser that it is a loser, they don't forget that relationship, and those roles affect their future chances of winning and losing against other lobsters.  "Memory of status lasts longer in losers of fights than in winners," Dr. Kravitz wrote in his groundbreaking 2004 paper Long-Term Consequences of Agonistic Interactions Between Socially Na├»ve Juvenile American Lobsters (Homarus americanus).

Dr. Kravitz went on to discuss how levels of the neurotransmitter serotonin appeared to be a key factor.  When lobsters won a fight, their serotonin levels increased.  When they lost, the levels decreased.  Experience caused a biochemical change that affected their future chances of being a winner or loser.  He found that by injecting the lobsters with serotonin you could artificially alter their abilities as a competitor.  When he introduced performance-enhancing levels of serotonin into a losing lobster and put it back into interaction with a winning lobster, the previous loser would aggressively attack the previous winner until it won or was killed.  The naturally superior lobster would exhibit signs of confusion at the unnatural aggression and competitiveness of the lobster it had previously easily beaten, and when it lost its serotonin levels would drop and it would become a loser.  Its own performance level artificially enhanced, the newly-crowned winner, naturally an inferior competitor, would experience a rise in its natural serotonin levels, effectively coming to believe that it was genuinely a winner.

Sunday's Osaka International Women's Marathon is the Kayoko show.  The Rio Olympics on the line.  Kayoko Fukushi (Team Wacoal), half marathon national record holder, Moscow World Championships marathon bronze medalist, the great hope for the future of Japanese women's marathoning who just can't seem to live up to that expectation.  Beaten down by Liliya Shobukhova at the 2011 Chicago Marathon in a Russian national record performance that was later revealed to be bullshit.  Coming back this year to Osaka as the 2013 winner, but having again been beaten down in that race by Ukranian Tetyana Gamera in the first of three-straight Gamera wins that were likewise revealed a few months ago to have all been bullshit.  Fukushi has never looked like she really believed herself to be a marathon winner.  How different would she be if she had actually won that fight against Gamera?  When you frontrun a race the entire way only to lose to someone who seemingly effortlessly blows by, the damage is done, you believe yourself a loser even if the other person is later revealed to have had their performance levels artificially enhanced. It's not easy to simply talk yourself past that even if you are not a lobster. "Changes in gene expression might underlie these changes in behavior, since it is unlikely that purely second-messenger-mediated mechanisms would last for days," wrote Dr. Kravitz.

So, with a spot on the Rio Olympic team up for grabs in Osaka this weekend, it's Fukushi's for the taking.  Sub-2:22:30 is the hoop to jump for selection.  There's nobody else her caliber in the field with the possible exception of 2014 World Half Marathon bronze medalist Sally Chepyego (Team Kyudenko).  Can a win in Osaka undo the changes caused by having been the superior athlete and still losing to a weaker athlete whose performance was artificially enhanced?  And what of the people who had responsibility for the artificially enhanced athlete(s)?  The Guardian has seemed to show signs of already wanting to rehabilitate Russian Andrey Baranov, agent to Gamera, Shobokhova and a seemingly infinite list of other banned athletes, for his role in revealing the Russian Federation and IAAF's shaking down of Shobukhova and other Russian athletes to conceal their drug use.  Whether you think Henry Hill was a hero or lowlife scum depends on your personal values, but this glosses over the fact that three-time Osaka winner Gamera was not Russian, and neither was Baranov-represented runner Aliaksandra Duliba of Belarus, suspended earlier today for biological passport violations just like Gamera and Shobukhova.  Whoever in Russia was ultimately behind its doping program may well have been influencing other former Soviet nations, but whatever the truth is it's clearly more complicated, and Baranov remains the link.

Gamera and other suspended Baranov athletes didn't come to Japan on their own either.  Osaka and other races continued to invite them, as recently as the end of last year.  In November one Japanese race official and IAAF-licensed athletes' representative with a long history of working with Baranov emailed a prominent formerly Japan-based athlete who has been vocal about the Russian and his crew, defending Baranov in an apparent effort to apply pressure on the athlete for speaking out.  Whether complicit or hopelessly naive, as the resignation of Economy Minister Akira Amari earlier today over a bribery scandal shows there are sketchy mofos in Japan just like anywhere else.  How much damage have they done in reinforcing the mindset among Japan's athletes that they can't compete against foreigners, that they are losers? 

Despite all that, let's hope for the best for Osaka.  A solid race by Fukushi with good competition, from the promising Risa Takenaka (Team Shiseido) and Yuko Watanabe (Team Edion), from the debuting Misaki Kato (Team Kyudenko) or her teammate Chepyego, or from one of the scad of university runners running the marathon for the first time.  A race that can undo some of the damage in time for Fukushi to face the bigger fish waiting in Rio.

Excellent commentary Brett! For what it's worth I will yell at Kayoko Fukushi "YOU ARE NOT A LOBSTER" as she sweeps past us half marathon runners! Really looking forward to seeing the women come in. Weather is looking prime for it too.

Respect to JNR for banging on about the Baranov connection for the past few years while so much of the the athletics press (and of course mainstream press) either ignored or didn't seem/want to join the dots.
Would love to see Fukushi run well and book a ticket to Rio - been a fan since she passed something like 15 runners as an 18 (?) year-old in Corporate Ekiden years and years ago.
On the Baranov front, I'd be curious to know when (yearwise) you first became aware of the bad smell around him, Brett. I looked at the bottom of the article to see if there was a JNR catalogue link for him to perhaps review your earlier articles. No specific "Baranov" link, but will be happy to testify in the future that you were definitely the first to identify "lobster" as a potential related issue...

Now THAT'S an interesting post!

THIS was a really really great read!

Scott, I will join you in chorus. Kayoko is no lobster. Watching her race at Moscow send chills up my back.

Brilliant piece of writing Brett. I wonder if Fukushi had any inkling of what you wrote before her race. From your account she sure took the bridle and ran with it. What a superb victory!

Japan's 2020 Tokyo Olympics Marathon Trials Are Here - MGC Race Viewing Guide

It’s almost here. Japan’s 2020 Tokyo Olympics marathon trials. The Marathon Grand Championships Race. All of Japan’s best marathoners. All in one place. All in one race. What the people have always wanted. The first national Olympic trials race to be recognized with Gold Label status by the IAAF. The only one that legitimately met the Gold Label requirements. It was the hardest marathon ever to qualify for. It should be the best marathon of 2019. It could be the most tedious. Maybe both.

If you’re in Japan you can watch the live broadcast of the men’s race on TBS at 8:50 and the women’s race on NHK starting twenty minutes later. If you’re not in Japan your options for being part of it are limited. There is an official live stream of the men's race via Paravi, a paid service with a 30-day free trial. It's not clear if it's available overseas and signup looks to be only in Japanese. NHK's TV broadcast is available in some areas outside Japan. It’s also live streaming b…

Nakamura and Maeda Win Japanese 2020 Olympic Marathon Trials

After an almost two-year qualification period that made it the most difficult marathon in history to get into, Japan's Marathon Grand Championship 2020 Tokyo Olympics marathon trials went off perfectly Sunday in warm and sunny conditions. Shogo Nakamura (Fujitsu), 4th in Berlin last year, and 2018 Fukuoka winner Yuma Hattori (Toyota) went 1-2 in a 3-way sprint finish against national record holder Suguru Osako (Nike Oregon Project) to score places on the Olympic team, with 2017 Hokkaido Marathon winner Honami Maeda (Tenmaya) taking the women's race and 2018 Hokkaido winner Ayuko Suzuki (Japan Post) holding off Rei Ohara (Tenmaya) to join Maeda on the Tokyo lineup.

It was a sign of the level of commitment that this generation brought, of what next summer's Olympics are going to be like, that both the women's and men's races went out at national record pace, but the two couldn't have been more different. In the women's race, 9 of the 10 starters went out fas…

Japan Announces Doha World Championships Team

Following the end of the qualification period for the 2019 Doha World Championships, the JAAF announced additions to the initial Japanese National Team roster released earlier in the summer. Along with the additions, the JAAF made public that Abdul Hakim Sani Brown (Univ. of Florida) will not run the 200 m in order to focus on the 100 m and relay, and that Kazuya Shiojiri (Fujitsu), the only Japanese man to have cleared the Doha standard, will not race due to an apparent injury following a fall last week in Zagreb. Final changes to the team roster, if any, are expected to be announced Sept. 17.
