Dathan Ritzenhein just announced that he’ll be running the New York City Marathon this November, joining a stacked field that already includes Haile Gebrselassie and Canadian hope Simon Bairu. One thing that jumped out at me from the press conference (as reported by Letsrun) was his coach Alberto Salazar’s assertion that Ritz’s injury problems are a thing of the past thanks to some high-tech analysis:
“Gordon Valiant – the head of biomechanics for Nike – did an evaluation of Dathan and was able to find some things that are unique to Dathan with the way he runs and strikes his foot. With that (study completed), we now have some modified inserts. I wouldn’t call them orthotics – just an insert into the shoe where he has an abnormal amount of force near his third metatarsal. It seems to have alleviated his symptoms completely and we’ve retested him in the lab and shown those forces have been lessened tremendously.”
For those who’ve been following the barefoot running debate, this should raise some flags. For years, critics of the big shoe companies have pointed out that measuring forces in a lab setting doesn’t necessarily equate to a change in injury rates. Australian minimalist advocate Craig Richards said as much in an article I wrote back in 2008:
“Shoe researchers and manufacturers will try and bamboozle you with the results of hundreds of biomechanical studies,” [Richards said]. While these studies tell you how your stride is affected by the shoe, “they cannot currently tell you what this means for either the injury risk or performance of the wearer.”
Fair point — though, as I pointed out last month, minimalists are suddenly more enthusiastic about biomechanical studies now that Dan Lieberman and others have provided them with some studies of their own.
Anyway, we now have a study (with n=1) in which the manipulation of biomechanical forces in the foot is hypothesized to solve a longstanding injury problem. The outcome measure: whether Ritz makes it to New York in one piece, with an uninterrupted build-up. Here’s hoping!
