No need...

Taken from the CGM thread :-

High intensity training also powerfully affects the central governor, re-setting it so that it allows increasingly higher power outputs before being tripped. One of the reasons that high intensity training causes immediate performance improvements, improvements that have been shown to occur in the absence of physiological changes unlike rising in the Free Fatty Zone(i.e. no changes in lactate production, mitochondrial density, heart size, capillary density, muscle fiber size, etc), is from the re-setting of the central governor at a higher level. High intensity training helps re-set the central governor so that it allows a greater mass of muscle fiber to be activated at one time, resulting in a higher total power output.

For physiological changes riding the in the Bi STF/Free Fatty Zone is the right way...Downside to training in this zone the response is slow. For someone like Ryder Hesjedal of Sliptream Sports who has been coached by Juerg Feldman in the past has spent many years riding in his FFA zone since he was a junior. His Lactate Balance point is around 170BPM where his body is able to produce and clear lactate from the working musscles. Riding the majority of all these years under his balance point he's trained his body so it's using mainly fats for a fuel source. So once he's above 170BPM he's starting to tap into his glycogen stores. Also the other benefit he's not been burn out from high intenisity training. Ryder & Geoff Kabush (also coached by Juerg) are the only 2 juniors from the Canadian squad of their time who are still competing. Reason Juerg thinks they are still competing unlike the other juniors is because their program was geared to long term development, around 90% in the FFA zone training and the remaning 10% high intensity.

One thing I would argue with the article is using percentages there's no guarantee that 78-80% is the same zone for everyone. We are not machines but a physiological system.
