I'm not sure about this one, however, nor have I heard anything about it. I know many athletes will ice their muscles after games or practice, but this is something they do to decrease swelling of the joints.
What I do know is that any time your body is brought in a cold environment, blood flow will decrease as your HR will slow, and your blood vessels will constrict. To my way of thinking, this lack of blood to the muscles will decrease the amount of nutrients needed for recovery and growth.
any other thoughts, anyone?? I'd love to be told that I'm wrong.
