Champion 6046 New York, NY | Subject: RE: HUGE difference in FTP outdoors vs indoors KathyG - 2008-11-06 11:51 AM I'm guessing part of the difference Cat is that your VI on the Baker course is 1.1 which bumps up your NP compared to your VI that is closer to 1.0 which I'm guessing was more the case indoors test.
ok here is the whole indoor test: Power-Tap #1: and here is CBTT Duration: 29:39
so yes, VI is higher on CB, I think now that I have had all this great input and time to examine that it is a combination of indoors without adequate fans, after long day at work, and 3 days after the outdoor effort and not resting rather swimming and lifting the days before the indoor....
so will look ahead to when the next one is - the remainder of the OS I am doing indoor TTs.
meanwhile I am tempted to use my last VO2max/LT testing for my power numbers (FTP 170) as it is inbetween.....

Expert 1049 Burnaby, BC | Subject: RE: HUGE difference in FTP outdoors vs indoors I would tend to agree that it probably comes down to cooling indoors. I've watched even my own "easy" days drop 20W for the same RPE just because I forgot to open the patio door and turn on the fan. Closely followed by consistency. As you described, training load, rest, workload, motivation, environment, and duration were different between the two tests. It makes sense to just choose a date and change over to the method that most closely resembles the majority of your training locations. If you mainly train indoors, test indoors so the zones are applicable. If your familiar with design of experiments (DOE) it comes down to holding constant all the variables you can so you can use the results to make conclusions about the variables you can't hold constant. |

Master 2491 | Subject: RE: HUGE difference in FTP outdoors vs indoors In the winter, I usually still open the sliding glass door some when it's below freezing, just because it gets too steamy and sweaty otherwise. I'm wearing gloves and neoprene booties, but the rest of me would still overheat due to the lack of wind. |

Extreme Veteran 454 OKC | Subject: RE: HUGE difference in FTP outdoors vs indoors Can't remember the name of it, but Hunter Kemper's coach has a book out that talks about fatigue curves. Very interesting and to me seems like it holds a lot of potential for setting zones even more accurately and/or predicting performances. Much like the Monod model. Anyway, TriToy: I have the KK trainer with a conti hometrainer tire, and I make sure to follow the instructions on tightening the drum - my outdoors efforts are indistinguishable from my indoors (288 last indoor 20min test, 294 last outdoor). YMMV. Also, similar to what Rick was saying, I can always put forth a higher effort during a race, not even close. Especially for running in the fall, there's a 5k every weekend it seems. Just cut out your long run & tempo run, then go race. Doesn't have to be a big production with a taper and travel. Spring usually brings cycling club time trials - check with your local bike club. |

I think you are refering to the critical power model which uses short duration tests and it can help you predict your power curve at other durations rather accurately. |

Coach 10487 Boston, MA | Subject: RE: HUGE difference in FTP outdoors vs indoors Daremo - 2008-11-06 11:42 AM true dat!The athletes out there who employ coaches are usually looking to improve for racing and have some guidance. And while compromises will always have to be made, there is still no better baseline than race data (IMO). |

I think you are refering to the critical power model .... It's similar to the Monod (i.e. critical power) model. But Monod is a regression of work vs. time, whereas this is simply the decay rate between velocity (or power) and the doubling of distances, similar to the old runner's rule, except this is individualized (& easy to apply for swim/bike/run). The book btw is "Championship Triathlon Training". |
