Testo: <blockquote data-quote="gioca63" data-source="post: 6880460" data-attributes="member: 15179"><h3>Andrew Coggan</h3>13 mar 2002, 17:18:00a <a href="mailto:wat...@topica.com">wat...@topica.com</a>I'm sure most people here remember the classification scheme Iproposed:<a href="http://www.topica.com/lists/wattage/read/message.html?sort=&mid=901936066&start=0" target="_blank">http://www.topica.com/lists/wattage/read/message.html?sort=&mid=901936066&start=0</a>When I formulated this, I based the "levels" on 40k TT power, since thelatter correlates highly with lactate threshold, 40k is a standard TTdistance, and one of the better uses for a power meter (IMO) is as apacing device in flattish TTs. A suprising (to me, anyway) number ofpeople, however, responded that they didn't know their 40k power, eitherbecause they hadn't done such a TT, or if they had, they didn't usetheir power meter. One simple solution to this issue is to just do a TTin training (y'all *do* do TTs in training, don't you? <g>). However, analternative would be to simply base the system on critical power, asdetermined using the method we've been discussing. In essence, this isreally the same thing, because critical power also correlates highlywith lactate threshold (and in fact, you can view critical power asbeing your "functional threshold power"), as well as with TT performance(e.g., Smith JC, Dangelmaier BS, Hill DW. Critical power is related tocycling time trial performance. Int J Sports Med 20:374-378, 1999). Theadvantage here is that it may be easier to work a few relatively shorttime-to-fatigue tests into one's training to track changes in criticalpower, vs. doing a full-blown TT. So, in case anybody finds thatapproach more appealing, here are the seven levels expressed as apercentage of critical power (as determined using bouts of 1 to 10 minduration):level 1, recovery: <48% of critical powerlevel 2, endurance: 49-65% of critical powerlevel 3, tempo or fartlek: 66-79% of critical powerlevel 4, threshold: 80-92% of critical powerlevel 5, aerobic power: 93-105% of critical powerlevel 6, anaerobic capacity: >105% of critical powerlevel 7, anaerobic power: N/aThe verbal descriptions and perceived exertion guidelines I gavepreviously would remain the same, but the heart rate ranges would needto be expressed as a percentage of heart rate at critical power (whichwill be closer to maximal heart rate than 40k heart rate). I won'tattempt to derive new heart rate guidelines, however, since there willbe some individual variability (again, see my initial post), and thewhole point is to have a power based scheme anyway.Note that this "translation" from 40k power to critical power is basedon the assumption that you can sustain 85-90% (mean 87.5%) of yourcritical power for a 40k. This assumption is based on somewhat limiteddata, so there is room for a little variation in the above percentages.However, it does make good sense, in that leve 5, aerobic power,overlaps 100% of critical power. This is what you would expect, sincecritical power as determined using bouts of 1-10 min duration is goingto close to, although somewhat lower than, power at VO2max.Anyway, I thought that some might find this alternatve formulationuseful...it is, though, essentially just another way of expressing thesame ideas (i.e., training by power with levels defined relative tolactate threshold).c era una volta coggan che faceva pure le percentuali con la critical power</blockquote>
