Compression shorts have been around for years. However, their use across all athletics has been increasing recently. This is, in part, due to companies such as Nike and Under Armour creating different types of these thin moisture-wicking materials. Now many athletes wear them because they are sponsored by a famous athlete, or they think it is cool to wear. However, the use of compression shorts is much more than just a fad.
Compression shorts serve multiple purposes for athletes, both male and female alike. For starters, they help to keep the leg muscles warm, due to the compression action they supply. This in turn, helps reduce the possibility for a number of muscular pathologies. They also reduce the friction and help to dissipate moisture. Friction plus moisture can lead to many skin pathologies such as Jock Itch, Chaffing, Folliculitis (inflammation of hair follicles), and fungal infections.
For men, wearing compression shorts helps to protect your manhood. Now I don't know a single man who wouldn't want to benefit in this aspect. Protection from Testicular Torsion and blunt trauma is high on my priorities list when competing in athletics. Superficially, they look great on women. Really accentuating their curves, herein lies another benefit for men.
Personally, I wear compression shorts underneath my regular shorts whenever I take part in anything that requires me to work up a sweat. Whether I'm going for a run, playing a pickup game of basketball, or lifting weights at the gym. So if you own a pair, you understand my affinity for compression shorts. If not, pick up a pair, what's the worst that could happen, you start to like them?
