Compression Garments; Do They Improve performance?

While running in central park or training in the gym, I occasionally see people wearing compression garments, which have become popularized by many clothing brands (such as Under Armour).  Do compression garments enhance athletic performance when it comes to strength or endurance?  According to new research, maybe not! One article examined how 3 levels of upper thigh compression shorts effect performance on an explosive lower limb task, measured by a vertical jump test. Results indicate there was no significant difference in max/mean/median jump height in subjects who wore compression garments versus controls. The second article researched what effect lower limb compression sleeves had on highly trained runners in regards to running economy and mechanics. Again, results demonstrate lower limb compression sleeves had no significant effect on running economy (submaximal VO2) and mechanics (various phases of running cycle). If, wearing compression garments DURING endurance/strength tasks have no effect on athletic performance, how about wearing them before or after?  Click the links above for more information.
