Anti-oxidants are somewhat baffling. I have seen several studies show ALA improves insulin sensitivity in diabetics; and that anti-oxidants can improve muscle protein synthesis, particularly in elderly populations.
It may be the case of acute vs. chronic. As is the case with acidity - blunting chronic acidity by consuming certain foods appears to increase protein synthesis. But bluting the acidic response during/after exercise attenuates the release of growth factors.
So maybe the studies that show benefits are for those who have chronic oxidative stress - elderly, obese, diabetic - but perhaps one bout of oxidative stress daily, in healthy young pops as your study examined, is good?
Kind of the case of a good stresser, versus a bad stresser. And finding the line between the two.
Not sure, just throwing something out there.
