I have seen heat stroke in military training environments. Highly fit Marines in Quantico, VA for example. Maybe someone currently there can get you some data. I bet there are &gt;18 cases per year, unfortunately some including death. My experience is ALWAYS in hot/humid weather, with higher prevalence in May/June when personnel are not acclimated and there is a high heat period (+90d). Clammy skin and incoherence are highly reliable signals for first responders. But maybe this buttresses your argument that CHI marathon participants arent really experiencing heat strokeAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-753215493005715353.post-990757386951637822008-10-26T18:56:35.773+02:002008-10-26T18:56:35.773+02:00Hi Jen<BR/><BR/>Thanks. Without giving the whole heatstroke thing away, you'll find that heat has little to do with heatstroke! Even the table shows that heatstroke is not determined by the air temperature - there's no pattern, no "critical" air temperature at which heatstroke is more likely to occur - it's a problem of physiology, not environment.<BR/><BR/>The issue of whether the people are acclimatized or not is also a really interesting one. If they are NOT, then the chances of heatstroke developing (according to a classic theory that the person runs themselves into trouble) are DECREASED, because as you rightly say, the perceived effort is so much higher in the heat, and that will mean that an unadapted person is LESS likely to have the capacity to override their perceived effort and run themselves into trouble.<BR/><BR/>All of this is of course irrelevant, because people who do get heatstroke (real heatstroke, that is, not this 'pseudo-heatstroke' that everyone gets when it's slightly warm!) can't blame the environmental temperatures or humidity anyway!<BR/><BR/>Cheers<BR/>RossRoss Tucker and Jonathan Dugashttp://www.blogger.com/profile/08206700707221642727noreply@blogger.comtag:blogger.com,1999:blog-753215493005715353.post-80665963290806550752008-10-26T14:43:39.235+02:002008-10-26T14:43:39.235+02:00Great cartoon... it would be interesting to see if these documented cases of heat stroke involve athletes not acclimatized to the "heat" prior to the start of the event. The perceived effort is so much greater if you are training in cool conditions and suddenly racing in warmer conditions. Heat acclimation makes an enormous difference.Jenhttp://www.blogger.com/profile/09636190133893025494noreply@blogger.comtag:blogger.com,1999:blog-753215493005715353.post-87310837628962535912008-10-25T15:56:38.217+02:002008-10-25T15:56:38.217+02:00Looking forward to it!Trihardisthttp://www.blogger.com/profile/09959976526615399378noreply@blogger.com
