Yeah.

I'll do it the best I can without getting like way too complicated on how the accelerometers measure physical activity.

So yes, not intensity, not based on heart rate in this study, which would be the common convention.

And maybe your wearables measure that using, you know, heart rate that wearables we have today, like your, you know, Apple watch.

So.

An accelerometer is literally a device that you wear on your wrist and it is measuring the direction of movement and the physical intensity of movement.

So if I move my wrist, say slowly, that might be light intensity activity.

If I move it more vigorously, that might be vigorous intensity.

So this accelerometer device is measuring the intensity of people's movements throughout the day.

direction of that intensity because it just has this physical accelerometer in it, which just measures the direction and the intensity of physical activity.

And so every 10 seconds throughout the day, it's measuring their intensity of physical activity.

And then based on a certain threshold of how intense their movement is, that would get bucketed into being a light intensity activity, a moderate intensity activity, or a vigorous intensity activity.

So every 10 seconds, this thing is measuring, you know, what type of activity you're doing.

It gets bucketed into one of those three intensities and then summed throughout the day and then throughout the week to say you did this much vigorous, this much moderate and this much light activity.

So it's a little bit difficult because most of the devices we have these days are not accelerometer based.

They're either heart rate based or they're actually using a GPS like most of these devices.

But I think that's the best way of describing it.

But the important thing there is that

This is how the intensity was measured in this study, not using, say, something like a heart rate.

It would, and that would be, I think even regardless of the,
