In the past I have not been limited by my anaerobic power, I was limited by aerobic power. Greatly improved aerobic power and seeing good results after base and build, is it a good idea to do a 8 week block focused on anaerobic power, given that it has the potential to negatively impact my aerobic power which I think is more important for the race I do.
I have my first properly anaerobic session tonight, Striped+1. One of the benefits of this is raising my anaerobic capacity, the other result of this session is that my VLa Max is going to increase, given the very high intensity of the intervals and the long rest periods relative to the work, ensuring I am fully anaerobic for most of the intervals.
Here is my dilemma, my top end has never been a limiter for me, my 1 minute power has always been good. However, my 10 minute+ power has always been a limiter which is driven by FTP and aerobic power. After a winter of a ton of volume and high volume SSB, followed by high volume general build my FTP and muscular endurance is much improved and after a couple of early season races I am getting in moves and riding with guys I never would have been able to ride with last year, plus my top end still seems quite good despite not doing any specific work on it, i might not be quite as snappy as last year but I think at the moment, that is a good trade for the longer road races that I do.
So my question is can i raise my anaerobic power without increasing my VLa Max a lot, my general feeling on this is probably not since the two seem quite dependent on each other, but I don’t fully understand that relationship myself.
What I was planning to do to potentially stop a large increase of Vla Max was to add half an hour zone 2 to the end of these sessions when I am glycogen depleted, which should help. From other papers I have read, it seems that anaerobic gains mainly come in a 2-3 week period quite quickly. So I am also thinking for the first 4 weeks of specialty, instead of doing an anaerobic session on Tuesday and Thursday, just doing an anaerobic session on the Tuesday and doing a supra threshold or VO2 session on the Thursday, like pisgah+6, Matthes+3 or Dicks-1. And then only starting 2 anaerobic sessions a week in the second half of specialty. The weekends for me, are either long 2-4 hour road races or long endurance rides, generally 3+ hours, and I ride on both Saturday and Sunday.
Any thoughts appreciated, that is a lot of info and I have tried my best to include everything but I may have missed a couple of details. Potentially an interesting discussion to be had anyway.
