About Rollerblading / inline skating training zones

Hello everybody,

I was wondering if any has any experience/studies with how rollerblading translates to running / trail running. The thing is that a couple of weeks ago a soleus injury that I have been dragging for some time reappeared, and taking advantage of the fact that I had some skates at home and that it is an exercise that does not exercise the soleus, I have started to do routes of 15-20km, as entertainment but also with the idea of incorporating it as cross training. I’ve been skating and some field hockey for several years, so my technique is adequate enough and the issue of falling is not a problem (although obviously a possibility).

My curiosity is how skating transfers to running, both in muscle groups and HR zones. Regarding the former, although the movement of skating is more lateral strength at the quad level and more fluid without the impact of running, both glute and quad are recruited, especially when we’re talking about high intensities or climbs. Secondly, the maxim of running at z2 by sensations comes to talk about “easy runs” as those where you can hold a conversation, which in my case is a bpm of about 155-160. The point is that in skating I can skate at high z3 or low z4 with no problem talking, and hold z5 for longer periods of time than I do in running. Obviously, even if the effort is sustained, relying on the inertia of the wheels makes the perceived effort significantly less, and especially less muscular. Does the “talking” criterion apply to all sports?

Just wondering if any of you have any ideas or insights on this topic.

Thanks,

Manuel

Not sure if this is an idea or an insight—probably an idea.
I train with inline, cycling, and a bit of running. For road sessions, I switch between cycling and inline based on weather and mood, translating cycling power targets to RPEs for inline. Running feels like a different game, maybe because I’m not great at it.
