That hat is signature but it also holds heat in, notice he perspires more than his opponent. Sweating causes dehydration and fatigue. Heat escapes through your head. GET RID OF THE HAT, STAY COOLER ANDY.
Pay close attention today. His dad wore the same hat. I've never seem him play without it. Correct me if im wrong. I dont mean signature as in a plain white hat but the fact that he always wears one while playing tournaments.
* Wear one layer less of clothing than you would wear if you were outside but not exercising. It's also better to wear several layers of clothing rather than one heavy layer. You can alwaysremove a layer if you get too warm.
* Use old mittens, gloves, or cotton socks to protect your hands.
* Wear a hat, since up to 40 percent of your body's heat is lost through your neck and head.
uh...is it really that big of a deal if he wears a hat? you would think if roddick knew he were hot/sweating too much he would take it off. btw, thanks for letting me know what I should wear on cold days.
