Okay, rolling is not strictly anaerobic, but it is not aerobic at all. It's far too unpredictable. It cannot be compared to long, steady, unchanging motion like running. Tell me I'm wrong there, go on.
You are wrong.
How is something not strictly anaerobic but not aerobic "at all" is there a third choice?
Aerobic capacity will lower the increase of lactate and allow for a faster recovery, its a combination of 2.
Again, if rolling was not "aerobic at all" you would be able to roll without breathing or your breathing patterns wouldn't change.
-The muscles work anaerobically, using anaerobic glycoglysis to make up for the lack of sufficient oxygen.
-Lactate is removed at a certain rate and metabolized back into the usable pyruvate by well oxygenated muscle cells.
What does it means?
It means that a high VO2 max can benefit the anaerobic lactic metabolism in 2 ways.
1.- The higher the VO2 max, the more oxygen present in the blood, there is a lower demand for the muscle to go into anaerobic metabolism.
2.- The higher the VO2 the more well oxygenated muscle cells with the ability to recycle lactate are present.
So in the end its directly related to rolling cardio, but its not the only thing that its relevant.
As people have mentioned before, the best way to train is
1.- Fartlek interval training
2.- Running at 100% for a set amount of time, in this case the duration of a match and resting the minimal amount between matches. This to increase AnT.
Pacing is bad when training for grappling, when you run for a set amount of time or distance like 1500, you should be outrighjt sprinting the moment you start and basically be dead when you finish, trying to be around 200+ heartbeat rate.
