Remember the quote:<BR/><BR/>"AMPK is activated by any stress that inhibits ATP production or increases ATP consumption. This includes <B>hypoxia, heat shock, exercise, and glucose deprivation</B>. AMPK is also activated by the hormones leptin and adiponectin. As its name suggests, AMP directly activates AMPK."<BR/><BR/>Here's my theory. Note I'm <I>really</I> generalizing here:<BR/><BR/>Your "speed" (ability to run at X pace at MP HR) probably was a result of the heat acclimatization (which I'm very familiar with - running a few 18 milers w/12 at Half Marathon pace in 85-90 degree weather last summer with no hydration/food intake before/during it - that run had tremendous effects, even though I was close to the point of collapse - by contrast, training in Boston in the winter is just plain awful on so many levels).<BR/><BR/>Your marathon "endurance" - as shown by the decreasing heartrate over the race (while maintaining speed!!!!) was a result of superhuman efficient fat oxidation/glycogen utilization from the depletion and ideal intake of carbs before/during the race.<BR/><BR/><BR/>Here's a quote from Benji Durden (relatively low mileage 2:09 runner) I note from time to time:<BR/><BR/>"All my runs (including the repeats but not the races) were in at least one set of sweats (I went so far as 2 sets of sweats sandwiched with 3 rainsuits were PO2 tanks). ... Heat training can also be considered strength training since you are hauling all those heavey wet sweats around as you run. (;-)<BR/>Additionally you can look at haet training as a way to get altitude effects at sea level. The oxygen uptake system is effected by the partial pressure (i.e altitude) and temperature. The lower the partial pressure or the higher the temperature, the less oxygen the cardivascular system carries. By adapting to the stress of higher body temperature, the body becomes more effective at oxygen uptake in a manner similar to the adaptation to altitude." (how Benji trained)<BR/><BR/>Even though I can't find anything "scientific" to back it up, I'm certain that running in heat *and* humidity really does simulate altitude.<BR/><BR/>If there was a place that was 70+ degrees, humid, and at altitude, that's probably the place to train (like the Rift Valley - hahah).Anonymousnoreply@blogger.com
