Dr. Jocelyn Wittstein

Now, there are people who cannot do impact because, again, I'm a orthopedic surgeon.

I have so many patients like, that's great.

I would love to do that.

And I get tons of messages from people saying,

that's ridiculous.

I can't do that.

You know, and I'm like, I'm sorry, I'm just trying to share information about what jumping can do.

But there are lots of modifications.

And so if you have terrible knee arthritis and every time you jump, your knee swells, that is not going to be a good option for you.

You can do heel drops.

You can do jumping on a rebounder, which doesn't do as much as land-based jumping.

You can do jumping in a pool.

Again, not as much as land-based jumping, but better than sedentary.

And so impact, that's a broad category.

What about vibratory plates?

Yes.

So those have mixed results.

If you look at

meta-analyses of these, you know, you're certainly going to see like half of studies that had no effect, half of them had some effect.

The most effective, I would say like formulation, if you're trying to think about using a vibratory plate, uses a 30 hertz speed.
