That's kind of what I was guessing. But is that how it works?
Being a cyclist and weightlifter, I'm often wondering... Can I build more of both? Can I build the strength of both? Or to some extent, is it an either/or proposition?
I imagine you have similar thoughts relative to being a rower and weightlifter...
My understanding is that the transition isn't permanent.
The way I handle it is that when I row during weightlifting season, I do a lot of interval work (below the glycolytic level), which is type IIx (like weightlifting), and lots of LISS (type I). This keeps my aerobic base decent and my "burst ability" intact.
But my 2K times drop way off because I can't extend the opening and finishing sprints into the 90+ second range without hitting the glyco wall and forcing adaptation (type IIx flipping to type IIa) that I don't want.
Then when weightlifting season is over, I go through a "Hell Week" (old football term) for 2 weeks to start pushing the envelope on sprint duration.
If I've kept my aerobic base intact, by about week 4 my conditioning is where it needs to be and 2K times are getting closer to race times.
Rowing is probably a bit easier to mix with weightlifting than cycling because the races are very intense, but much shorter duration than cycling.
