Orange Fish said:See, that's a big part of what spurred my questions. You hear Bob and Phil throw that word around like it's going out of style, and I've heard top coaches say that Tempo riding is SO important (which I believe), but if it's so important, it seems as though the definition of it is a bit fuzzy.
When Bob & Phil are talking about Tempo I just assume they are using it to describe the pace of the race - kind of like how the tempo of classical music can increase or decrease - rather than a specific target or zone used for training/racing.
Quoted post said:I understand AC's %'s for power ranges in L3, and they make sense, but how about cadence? I haven't seen him prescribing a specific cadence, but have seen his article on low cadence work.
I've seen it at CTS where it's 75-80 rpm, but what about 80-85, 85-90, 90-95, 95-100, 100-110, 110+? If you keep the power in the same range, will you have the same adaptations - I say no. Why 75-80 over 100-110? Does the amount of improved glycogen storage from L3 riding occur more effectively (or faster) at 75-80 rather than 100-110 rpm? Does it have to do with speed of contraction, force production, muscle recruitment (all of which will be different at different cadences with all other variables remaining the same - right?).
Therein lies the $64,000 question. I know from personal experience (again, not very scientific) that when I go out for a 2+ hour ride I will use a much different cadence than I will for VO2 intervals. For VO2 intervals I find it better to rely on an increased cadence as well as higher gearing. Would a good coach have me do this? I don't know. But it does seem natural to do so.
I've read where CTS prescribes 75ish RPM's for the cadence on such rides but I don't recall the specifics as to why this is important.
Ric Stern has often stated that "one should train at a cadence where the rider produces the most power, provided it is between 80 to 100 RPM's". This seems to make the most sense because it takes into account the "specificity" of training - i.e. train at a cadence where you will be racing.
Is a slower Tempo ride better served by a lower cadence than say, a 25K Time Trial or something similar? I think the real secret then is to find if there is a logrithmic power curve where slower rides are more efficient with a lower cadence and faster rides are better served with a higher cadence. Simply plot the data and chart it.
That's one for people with much more expertise than I have for sure. :o
