Cold Weather Nutrition
Today on PowerBar's website
in the Nutrition Resources section, I read some useful, easy-to-understand information about keeping fueled up in the winter months for peak performance. For example: "...a day on the slopes for skiers has been shown to reduce muscle glycogen stores by 50%. If you start your day low on fuel reserves, or you don’t actively replenish carbs, those limited fuel stores can run dry, causing your performance to plummet. Thus a rise in elevation boosts your metabolic rate. It simply takes more energy to perform the bodily basic functions at higher altitudes.

Also, I wasn't aware of how much the cold weather can affect one's hydration
. I certainly don't feel nearly as thirsty running in cold weather as I do when running in the park in the summer. This excerpt begins to explain it a little bit: "...one of the first things that may occur in response to relocating to a higher elevation is a reduction in the amount of water that circulates within your body. This altitude-induced diuresis, or elimination of body water through urination, is theorized to help concentrate red blood cells that carry oxygen in your blood. A reduction in body fluids can also occur from exposure to cold (cold-induced diuresis). If exposure to cold is sufficient, circulation to arms, legs and skin can be reduced to preserve body heat and protect the body core."
