Actually Mitch it's not just an assertion, it's a fact. I also wouldn't just dismiss the CONI tests shine it was an extensively researched program backed by the Italian government. Also back in the early-90s there was a bunch of research done about breathing and wider bars here in the U.S. I remember the conclusion was that wider bars let you breath better, period. Wider bars did also create a larger front for the rider creating more wind drag. The main benefits come from better leverage and comfort for most riders.
The research was summarized in most of the cycling press at the time. Maybe someone on the list has the research handy and can post it for us. I'll ask the sports science guy at work and see if he remembers the study. I'll post again if I find out anything more.
I think in your specific case- and my case and pretty much every body on
this lists case- you're not riding to limits where a 5% loss in breathing
capacity would be very noticeable. Personally I like to switch it up and
ride all kinds of bikes with all kinds of bars. I can say that if I'm
zipping around town on my fixie I like narrow. If I'm on a long ride or
tour with hills I like wide bars.
