L.
Sorry, I must have missed your question. Let me give some more details. I'm most interested in increasing my power at longer efforts (5-30 minutes). I am not so concerned about my sprint power, which is pretty good even if I don't train it, at least on a flat. I do a lot of intervals in that range (4-20 minutes) as well as some shorter ones (1 minute at the shortest).
My feeling is that I gain the most muscle weight from the shorter duration intervals, where "shorter" means less than 5 minutes. I realize that 5 minutes is still a pretty long time from the standpoint of endurance, but that's my impression. I think I may even gain muscle weight from something like 12 minute hill intervals. The 2x20s don't seem to build my weight as much. For the other ones it's a tradeoff because I gain both power and weight, and my power/weight goes up. However, if there's anything I could do to keep my legs smaller and maintain the same power levels I'd really like to do it.
I was speculating that maybe it would help to do some long zone 2 rides? I don't really do much of that because 1) I don't have a lot of extra time to train and 2) I can't seem to hold myself back for a whole ride --- eventually I will find an excuse to go for it even if I originally planned not to.
Also, one more thing. Someone mentioned that weight gain is the difference between calories burned and calories consumed. Clearly that has to be correct. However, I'm pretty thin and I find that things aren't always so simple. If my body wants to gain muscle mass (due to heavy training) it's going to try hard to do it no matter what I eat. Even if I simultaneously cut back on calories somehow it manages to do more with less I find (possibly using less energy for other things?). On the other hand, if I stop training for a couple weeks then I start losing weight almost immediately even if I don't really adjust my diet (so my body is doing less with more). So it's not really that simple. I probably could starve myself a bit more than I do but I don't think that's the real source of the weight difference.
