Is There a Trigger for Preferential Transition Speed?

At zero, five and ten degrees, at these a less steep inclines, bio energetic aren't serving as the trigger for preferred transition. There's some other variable that's likely more bio mechanical or narro muscular in nature, that's triggering the preferred transition speed. At 15 degrees, oxygen is ot a premium because that 15 degrees, you're kind of running out of oxygen to maintain that high exercise intensity. So i going to ev me, mebe ta snuffer of the wrigter to go in general bu bore gongto try it.
