Wow! That was a great article. And it looks to be a great website. Thanks.
It was also a long article which I'm sure everybody didn't get through so here's a summary.
Research suggests that exercising in cold weather:
1. Suppresses the immune system,
2. Raises blood pressure,
3. Causes higher rates of glycogen metabolism,
4. Causes higher rates of fat metabolism.
All to a greater extent than exercising in warmer weather.
After continued training in cold weather all of these effects are diminished. So someone just starting to run in cold weather would experience more of these effects than someone who has been doing it for some time.
Does any of that mean a cold trainer has an advantage over a warm trainer in a cold weather race? Maybe #'s 2 and 3 give him an advantage but I doubt #'s 1 and 4.
