Maybe triathletes have a tendency to use more supplements, in general, and fish oil, in particular, than open water swimmers? Or maybe the population is a whole lot larger.
Skip Interesting theory. They checked for a bunch of different supplements and fish oil was the only one that emerged as problematic.
My (entirely unresearched) sense is that wetsuit use is much more common among triathletes. Maybe that could play a role too? :dunno:
Wet suits can, indeed, girdle the body in such a way as to potentially increase core blood pressure above and beyond what the water and cold already do. I also wondered if SIPE was more likely in fresh water or salt water, but it's rare enough that I don't think they had the data to know for sure.
Maybe it's that triathlete competitions are the msot populoar of "ultra..." sports (here by "ultra" I mean something significantly longer than a marathon.)
I wondered that, too, but it seems that most SIPE problems develop in the water, or very soon thereafter. I asked the lead researcher if the additional stress of biking and then running increased the likelihood, but he said it is induced by swimming. Interestingly, race horses have been known to develop pulmonary edema from running, but whether people can get it this way (i.e., with no swimming component) is controversial in the exercise physiology research world.
I suspect the main take away is don't take even the most "beneficial" of supplements in levels that would be virtually impossible to obtain through diet alone. I am not sure how many blue marlins Jeremy would need to eat a day to get the equivalent of 9 x 1200 mg capsules, but I daresay he'd weigh a bit more if he consumed his fish oil by eating actual fish as opposed to swallowing lozenges!
