My 5min and FTP in the power profile are at about the same level. My 5s and 1min are untrained. typically don't do max 1min efforts so this might not indicate much, but even when I do I still remain in the untrained level for 5s and 1min. Does this indicate I'm a slow twitcher?john979 said:OK. One thing I have learned is that without objective data, accurate analysis is impossible. Do you have a power meter? If so, you can get an idea of your fiber composition from your power profile.
