Qudrant analysis : Cycling peaks

[VO2max]

I need some clarification regarding quadrant analysis.

  

Which power must I use. If I want to analize a racing file for instance.

 

You need to indicate at what power threshold you would like to create a analysis. Is threshold power the same as functional threshold power or is it the average power of the ride you did that you try and analise - or do you use the nominal power of that specific ride. The way I understand it, it should be your functional threshold power. Is that correct.?

<?:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Which cadence must I use. How would I know what my threshold cadence is that must be used or do you use some or other standard like 88 or 80 or which cadence must I use. The average cadence for that ride or not.?

Thanks

You use the Average power figure and the average cadence figure for the ride you want to run the analysis on.

So, if you had a 40 km TT at an AP of 245 and an average cadence of 88 then you would use those figures.

thanx Bikemax

Huh? I feel like the brains are being sucked out my ears just reading this!!

It's easy.  You see you can split up the samples from your power meter into 4 quadrants.  One for low torque/low cadence, one for low torque/high cadence, one for high torque/high cadence, and lastly one for high torque/low cadence.  Then plotting the scattergram and your mean maximal power curve......

 

MichH, are you still there????

Cycling Peaks doesn't have a scatterplot chart does it?

 

 

[MichH]

Sounds scatterbrained to me.

 

Actually I'm just kidding. I too am a propellor head when it comes to stats. I once stayed late on a Friday night because IT had just sent me new data off my base and I was looking at new ways to analyse it! Nerd!

No, but you can download the Excel spreadsheet from their website.

Cool, more to play with!

There is a section on it in the "Training and Racing with Power" book. Haven't read it yet ...

 

ps Bruce I lost track of the thread about your 60m TT - you do it??
