VO2max Posted September 22, 2006 Share 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 Link to comment Share on other sites More sharing options...

bruce Posted September 28, 2006 Share 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???? Link to comment Share on other sites More sharing options...

MichH Posted September 28, 2006 Share 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! Link to comment Share on other sites More sharing options...
bruce Posted September 28, 2006 Share Cycling Peaks doesn't have a scatterplot chart does it? No, but you can download the Excel spreadsheet from their website. Link to comment Share on other sites More sharing options...
Windbreaker Posted September 29, 2006 Share 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?? Link to comment Share on other sites More sharing options...
