That study was specifically done with "trained athletes", for the rest of us, i.e. 99% of the population, the main effect of a 3 minutes long "all out effort" could just be an heart attack. Would they remain in zone 2 in this case...
You might need to re-phrase that. Or are you really implying that any of us non trained non athletes risk a heart attack if we go over zone two. None of my cardiologist say there is anything wrong with me staying in the upper zones for as long as I care to or am able to.
Might not be good training strategy. But it's not risking a heart attack for anyone that is otherwise healthy.
