I&...Ah, ok so we nailed your VT1 and VT2 perfectly! I'm not sure what the discrepancy is? You indoor FTP is probably biased. Recall that FTP is a "max effort" test, and indoor effort can be different than outdoor - http://www.muscleoxygentraining.com/2018/07/trainer-vs-road-cycling-psychologic-and.html. Given the agreement of HRV to the gas exchange numbers, those are your true stats. Ignore "fixed zone" recommendations. You are doing fine (just have altered perceived effort indoors).BJRMDhttps://www.blogger.com/profile/03840322337577591292noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-1792907782204908332022-02-20T06:00:07.332-08:002022-02-20T06:00:07.332-08:00Thanks.

Just to add to the conversation, VT2 HR 171bpm, which I was getting closer to in the ramp test.<br />So I could I explain the discrepancy I see between VT1 HR and the fact that I reach those values only if I do long sweetspot sessions? From my understanding VT1 should be around 75% FTP according to Coggan's zone, or upper endurance, in most people.<br />Could my muscular efficiency be underdeveloped compared to my aerobic one?SMhttps://www.blogger.com/profile/17640812290150797458noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-52232508852626169922022-02-20T04:57:23.893-08:002022-02-20T04:57:23.893-08:00The ramp looks great from a technical standpoint. ...The ramp looks great from a technical standpoint. I uploaded the results to here - http://www.muscleoxygentraining.com/2021/04/quick-look-at-someones-ramp-data.html. The HRVT is close to what you got (160bpm). If you have the raw VO2 test, I would like to see that too. If you just have the results, what was the VT1 heart rate?BJRMDhttps://www.blogger.com/profile/03840322337577591292noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-50228197963415137642022-02-19T14:10:49.032-08:002022-02-19T14:10:49.032-08:00Yeah, I am using an H10, artifacts are 0% from the...Yeah, I am using an H10, artifacts are 0% from the start of the ramp rate. Forgot to mention that the HR value where DFA crosses 0.75 matches the one recorded in a lab during a VO2max test. Here is the link of the ramp test: https://file.io/qzH63OO7EtTL.

The main one being artifact or device. Do you know what the percent artifact is? Are you using a polar H10? If the artifact is below 3% and you are using an H10, why don't you leave a link to your fit file (or raw RRs) and I'll take a look.BJRMDhttps://www.blogger.com/profile/03840322337577591292noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-74429822859131167162022-02-19T09:43:53.321-08:002022-02-19T09:43:53.321-08:00Hi Bruce,

That means I never see my DFA1 crossing .75 when doing sessions like tempo or sweetspot, let alone endurance, being both power targets and HR values at those targets lower than the one I measured in the ramp test.<br />What could it mean? Shall I re-do the ramp test to be sure?<br />SMhttps://www.blogger.com/profile/17640812290150797458noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-52066732413756945332021-11-08T03:14:05.913-08:002021-11-08T03:14:05.913-08:00I don't think it's the drinking but that y...I don't think it's the drinking but that your cycling power temporarily drops.
