HIIT is certainly more *stressful* in general. More cortisol during and after. But some people report a greater anti-stress effect after. Zone 2 will induce less cortisol overall vs. HIIT. Hard to say which is “better” because it may depend on what you enjoy doing.
Do you really think that the bodies of the participants cleared out the senescent cells that fast? I honestly highly doubt that. And why would the marker then rise again that steeply in 24 h? Are the cells back to being senescent again after a short period of normal function? Or have the participants "restocked" a fixed pool of senescent cells?
I rather think that this is a typical marker/outcome problem. Further, there are several functions to this protein (see for example here:
Is there any view of what is best for stress in general? HIT or zone 2 type exercise? Which removes cortisol better or is better for stress overall?
Great question.
