Cold baths for sore muscles?

A serious-runner friend of mine told me that after his long runs he takes a 15-minute cold bath. He said that the bruised tissue is first shocked, naturally, and the blood leaves the area, and retreats to the core (which is why taking a nip of booze when you’re freezing outside is ultimately counter-productive).

He said his sports doctor told him that after the soak, the body goes into hyper-perfusion, and all sorts of good things happen (I can’t remember the particular mechanisms he mentioned).

Any explanations?

Post match/workout/training ice-baths are the preferred option for athletes in a wide range of disciplines - rugby, football, runners etc. While there has not been much clear research, if it was counter-productive I suspect professional sports teams (where performance/recovery is closely monitored) would notice and stop using it.

Think of the cold baths as full-body ice-packs; reducing inflammation caused by stress from workouts (or runs or competitions or whatever).

It’s certainly true that this is widely used, however there have been other things that people do that are done because that’s what everyone is doing, then sometimes the science catches up and they stop doing them. A good example would be static stretching, which “everyone does”, has been counter-indicated, and now is getting reversed again. Maybe.

FWIW:

Actually I don’t mind being a bit sore after having exercised. I know that “no pain no gain” is not in fact true but psychologically a wee bit of pain makes me feel like I must have worked hard enough and more self-satisfied. Any one else odd like that or is it just me?

I thought too that ice-packs are dandy after contusions, but they only work within 10 minutes or something after the bruise.

The Wiki entry (and some of its cites) presents a lot of evidence as to it’s maybe-yes maybe-no-ness. (There must be a better word for what I just used.)
