I think so.

Why is everybody then still doing the cold water immersion after exercise?

I think it came from sports where you basically hurt the muscle, where there's massive inflammation, where there's blunt force trauma on the muscle, that actually you basically support the muscle in recovery, not the reconditioning, but basically minimize the damage

And then people started using it for other sports as well.

But I think for resistance training or for endurance training, you shouldn't be using it, at least not acutely after the exercise session.

I think it would be less.

So...

But the other question is then for your other benefits, whatever they are, of course, there's also a lot of discussions on that.

Do you need to do that 15 minutes?

Is it better to do it the other day?

At least the first few hours I think are essential for the muscle.

I would stay away from the cold there.

Is it okay to do it in the evening or the next day?

I would favor that as opposed to the other one.

I think we would have found exactly the same thing if we had done endurance training.

So this was resistance training.

I think if we had done endurance training, you would also have less of your amino acids that you ingest go to the muscle.

I mean, a lot less of all this kind of work has been done after endurance training, but it seems to follow all the same principles.

It's just the different sets of proteins that are being expressed to a greater or lesser extent after endurance versus resistance exercise.

But they're also responsive to nutrition, and so they should also be responsive to blood flow to the muscle.
