Cycling Fitness / Training Advice

S'wot I said.

Thanks, that's helpful. So it's basically analysing your Heart Rate response to your output, which is what i thought.

I wasn't planning on placing too much emphasis on it ajust good to know what it's based on. Is gonna be fucked up somewhat by the fact that, if it is looking at past rides and the current one, i've only just got the tool. Plus on turbo my Heart Rate is about 20% higher than outdoors on long intervals

@ttm
i think you need a snazzy watch thing to properly record it - don't think a garmin and HRM will do it

The recovery advisor seems to learn and get better after a while.

Initially I would get crazy suggested recovery times but most are now much more sensible (often <24hrs)

Sure.

anecdotal but a mate of mine got rid of his garmin for wahoo elemnt and he is well chuffed

If it's using HRV, which it should be as anything else would likely be little more than voodoo bullshit, it measure the tiny irregularity between each heart beat. Oddly enough, the more irregular the more recovered you are, the more regular the heart beat the more fatigued or stressed you are - see: http://www.myithlete.com/what-is-hrv/

I think it just looks at the session you've just done.
I do brick sessions. Often a second session results in the recovery time being less. Simply because that session had less volume/intensity. It isnt adding them up.

The thing with HRV is that you're supposed to measure it in the same position (say, sitting on your bed as soon as you wake up) and time every day. There's no point taking a reading straight after you've got off a turbo or after you've walked to work and had four coffees.

That's interesting. Suggests it is looking back at past data etc. Like a PMC i suppose - takes time to build up the past info

No it doesn't. It uses HRV measurement

"The Firstbeat method detects periods of stress, recovery, and physical activity from the HRV measurement."

"For the most reliable recovery analysis, sleep time is suggested"

"Quick recovery tests can be applied during awake time in cases when easily performable checks for recovery status are needed. The tests can be conducted routinely each morning,
before a training session or when preparing to a match. "

"Recovery assessments should always be started before hard training periods. "

Are we talking about the little pop up get on my 920xt when I save a workout?

Thats what I was banging on about at least.

OP was asking about 'Recovery Advisor'.

I dont have time to actually read what other People post. I have unqualified opinions to type......

I know. I spend my days CRUSHING THEM, CRUSHING THEM YOU HEAR!

FEEL THE CRUSH!

awkward boner

Ha!

I am a little skeptical about the VO2Max figures it produces though, it just told me I just set a new VO2Max of 66...

Yeh, I don't really understand how this is measured, and this is pretty unhelpful

My best (after two workouts) was 71, but the above page does say you need a few workouts for it to start being reliable

"The only direct way to actually measure maximal oxygen consumption is to use open-circuit spirometry in a laboratory."

"It is well known that there is a linear relationship between oxygen consumption and running speed. The oxygen cost of running increases when running speed increases. At identical submaximal speeds, an endurance athlete runs at a lower
percentage of his or her VO2max than an untrained person, although both maintain similar VO2 [6].
Technology (such as GPS sensors and foot pods in wrist devices or mobile phones) enables reliable measurement of running speed along with heart rate (HR). Therefore, these parameters can be monitored continuously and automatically during each workout. Because VO2max is a key variable to fitness training that needs to be easily measurable without additional protocols, an automatic VO2max estimation method applicable for any uncontrolled workout has been developed by Firstbeat.
The method is based on the well-known connection between heart rate and the speed of the activity (e.g. running, walking).

The following calculation steps are used for VO2max estimation:
1) The personal background info (at least age) is logged
2) The person starts to exercise with a device that measures heart rate and speed
3) The collected data is segmented to different heart rate ranges and the reliability of different data segments is calculated
4) The most reliable data segments are used for estimating the person's aerobic fitness level (VO2max) by utilizing either linear or nonlinear dependency between the person's
heart rate and speed data.

"VO2 Max estimator using the formula developed by James D. George in "VO2max estimation from a submaximal 1-mile track jog for fit college-age individuals." The equation was developed by having subjects run easy miles, which for the research was restricted to a minimum mile time of 8 minutes for males, and 9 minutes for females. The VO2 max estimate is calculated from a sustainable pace, and the associated heart rate. The calculated VO2 will be valid once your heart rate has stabilized at the pace you are running. This calculation will not be accurate during workouts such as tempo runs or intervals where effort is high or pace frequently changes. This data field is valid for RUNNING ONLY.

NOTE: This data field uses both gender and weight from the User Profile, the user profile must be accurate to receive valid results. The calculation also uses current speed and heart rate, so a heart rate monitor is required."

You love a copy and paste dont you!? Understand what vo2max is etc, just not really what the calculation is that an edge would do. I guess a HR and Power thing.

Al i really give a shit about though is - is my vo2 max better than LeMond's

If I read it, then I know how it works. If I copy/paste the text here, it means you know how it works and if I know it's on the forum and I want it again, I don't have to look for the PDF.

It's taking your HR and your pace and guessing what your Vo2max might be. That's it.

Your estimated VO2max is as meaningless as most of the other estimated values on the unit. Lemond's breakfast cereal has a higher VO2max than we do, but I'd crush him in a shot-drinking competition.

Excellent response
10/10

Any forum-recommended fans for turbo sessions? Not too bothered about noise volume.

I tried getting my missus to cheer me on but she got bored real quick so I've gone back to fan-less training outside.
