2 小时 41 分钟There's a much more recent study that took again older adults and randomized them across three different groups.
One was like a low intensity group.
Another group basically did kind of zone two type work on a treadmill three times a week.
And the third group did a high intensity interval training intervention, which was the Norwegian four by four protocol.
So four minutes, 85 to 95% of maximum heart rate.
They had a three minute rest in their protocol.
They did that four times over.
That's three times a week.
Three times a week for six months.
That's pretty intense.
What they showed was that that high-intensity interval training group,
they improved their fitness just as well as the Zone 2 group, interestingly,
but they had much better improvements in hippocampal function and maintenance of hippocampal structural and MRI scan.
And they maintained that benefit for five years after the six-month intervention.
So they worked really hard for six months, but that benefit was maintained for a really long period of time.
