There were two problems with the University of Udine researchers’ lactate-based hypothesis. First, there is no evidence that running pace is strictly limited by blood lactate levels. In short races, for example, runners routinely achieve blood lactate levels that exceed the lactate threshold value. If such high lactate concentrations are “allowed” in short races, how could they impose an immovable ceiling on running pace in other circumstances? Second, there is no mechanism whereby blood lactate could regulate running pace even if it did cause muscle fatigue. If blood lactate did regulate running pace throughout exercise prior to fatigue, then each runner would run the same pace in every runthe pace corresponding to the “right” blood lactate level. What the University of Udine researchers were forgetting, and what almost all exercise physiologists forgot in all of their work until sometime after 2001, was the role of the brain in exercise regulation. It is the brain that tells the muscles how hard to workin this case, how fast to runduring all exercise situations. Therefore, the true explanation of the natural running pace phenomenon must be seated in the brain. This truth was suggested by another 2001 studythis one performed by researchers at Wayne State University in Wayne, Nebraska. 4 Eighteen men and women were asked to complete 20-minute workouts at their individual preferred intensity level in three separate modalities: treadmill running, stationary cycling, and stair stepping. The physiological variables were all over the place in the three workouts. On average, the subjects completed the cycling workout at a much higher percentage of VO2max than the treadmill and stair stepper workouts and completed the stair stepper workout at a much higher percentage of their maximal heart rate than the cycling and treadmill workouts. However, their ratings of perceived exertion were almost exactly the same in all three workouts. Clearly, then, natural running pace and preferred intensity in other forms of exercise are not totally determined by physiology but are instead selected by feel. And where does feeling happen? In the brain.WatchFit – Fun and curious burpees exercise benefits Bestcelebritystyle
