Interesting article-"Quadrant Analysis" if you are willing to wade your way through it.
http://home.trainingpeaks.com/articles/cycling/quadrant-analysis.aspxFinally, it should be emphasized again that powermeters currently on the market
do not directly measure the force applied to the pedal
... the distinction between relatively low force and relatively high force pedaling is actually somewhat arbitrary,
since recruitment of fast twitch motor units really occurs in a graded, rather than a threshold, fashion.
In addition, muscle force and velocity, while important in determining fiber type utilization,
are not the only factors that determine recruitment patterns - for example,
as mentioned previously the duration of exercise also plays an important role,
and there are other factors as well
(e.g., the threshold for fast twitch motor unit recruitment is reduced during ballistic contractions).
Because of such considerations, "quadrant analysis" should be viewed as a general indicator of fiber type recruitment,
not as an absolute measurement.
what does "since recruitment of fast twitch motor units really occurs in a graded, rather than a threshold, fashion." mean?
