But what that trial did was they followed women.

I think most of them were on average when they enrolled them, like, 55.

And then they followed them for 16 years.

So now off to, like, age 70-ish.

This is really interesting.

I mean, they...

they had these supervised sessions, then independent sessions, and they carried this out all this time.

And then they followed their bone density over time, but they also followed, obviously, their fracture risk.

And so there are a lot of trials that really show you the impact of an exercise program on long-term fracture risk.

Because it takes a long time to measure.

Yes.

Again, I just feel like

Sometimes I feel like, why don't we have these trials in the United States?

Some of them are just not this good.

But in any case, what they found was over time that the women who participated in the exercise group as compared to the control group had approximately a 50% reduction in fracture risk.

But interestingly, near the end of the trial, you know, at first, the women who were doing the strength training, it included strength training and impact, and they kind of used periodizations.

It wasn't always intense.

Sometimes it was like less intense, but they did have periods of higher intensity.

And what they found was obviously a major reduction in fracture risk.

And earlier on, there were larger differences in bone density.
