What is it?
Quadrant Analysis: A means of analyzing powermeter data files to obtain additional insight into the neuromuscular demands of a race or training session.
Looking at how it relates to cyclocross was my focus.
First you have to look at what the four quadrants mean. (more can be found here if you want)
Q1: High Force and High Cadence- An example of this would be sprinting.
Q2: High Force and Low Cadence- An example would be steep hill repeats, big gear intervals and a lot of Mt. Biking and cyclocross resides in QII as well.
Q3: Low Force and Low Cadence- An example would be a recovery ride or just an easy ride around town.
Q4 Low Force and High Cadence- An example would be a Criterium or fast pedaling drills.
With the info telling me that Q2 is specific to cyclocross I went back and looked at some cross and mtb training days and races to put that to the test.
Nyes, Wells, and now Johnson spend allot of time on the MTB leading up to the cross season.
Here is the tall oak 6 hour team quandrant report.
36.9% of the time in Q2, seems like they are on to something?

Here we have Saturdays training session, 10 laps on the Dogfish Cross in Hermann race course.
54.9% Q2 - lots of high force low cadence work. Very specific to the demands of cross.

In June I did the Ballwin CX race. Q2 on that day was 52.6%

Now lets look at the MO State Road race, 20.8% Q2.
39.2% of the time was in Q4 ( Low Force and High Cadence)

So what does all that say? To me it says if you want to get better at cyclocross you need to spend a good portion of your time with High Force and Low Cadence workouts. And the quadrant analysis tool will validate your efforts.
Just under 6 days till cross starts!
