Why would it work better than doing anerobic intervals on the bike?
Like I said earlier there is no proof it will. But I don't believe that bicyclists are some freaks of nature and are the only athletes lifting does not help. When I looked back at my past seasons power outputs I noticed a trend. I would normally start out with a really good 5 sec - 1 min power but a low 60 min power (comparisons made with watt/kg). Which made sense, I lifted all winter and my legs were strong but not really aerobicaly fit. I would then stop lifting and work mostly on the bike. I found my 60 min would go up and surpass the year before but my 5 sec - 1 min would slowly go down. Now I could have just been making mistakes and not working on the anaerobic enough but I found one year that just lifting 1-2days a week to maintain, my 5 sec - 1 min did not decrease and even went up but just barely and the 60 min went up as before.
I believe I can spend a much shorter time in the gym working on my anaerobic power and spend most of my time on the bike working on my aerobic power during the season. I feel I only have to do enough anaerobic work on the bike to (for the lack of a better word) train the muscle to use that power in efficient way while biking. I also use the bike to get my body used to recovering from a hard anaerobic burst something that can not be done in the gym. In other words I use the gym to gain the strength (mostly in the winter, maintain in season and or work on power) and the bike (you can gain strength there also just not as fast in my opinion) to teach my body how to use it.
Like I said this is what works for me. I would never recommend starting this during your main part of the season. I am of the opinion that if I can work on it all winter in my down time I can come out of my build stage later alot stronger and start my aerobic and anaerobic interval work on the bike at a higher level. But I am not an elite racer and never will be. So in that vein find what works for you, if you do not believe it will work it won't. It took me 5 years to find what I believe works for me.
Alex has a different opinion, and has some studies that he finds more credible them me. Whoever you believe it does not matter. There is no magic bullet, it will take years of loggin all your workouts to figure out what works for you and those years, is in my opinion why no good study has been accomplished yet to date.
