what do compression shorts do
by Melaina Juntti. Many athletes swear by expensive compression shorts, socks, tights, and other garments. These tight-fitting items are thought to hold muscles firmly in place and improve blood flow to the muscles, thereby boosting athletic performance. But according to a new study of elite male runners, none of that actually happens.
What to Wear/Bring: 1  Moisture wicking shorts. 2  Moisture Wicking Shirt (Do not wear cotton)It was about 60 degrees and overcast when we ran the Spartan Race, so I wore a long sleeve, black, Nike Dri Fit shirt. 3  Spandex Underwear/Compression Shorts.  Shoes you plan to donate after the 1  race. Gloves.
