How it works: The foot striking the ground sends vibration up the runner’s leg and causes muscles to shake. This is thought to damage muscles and add to post-exercise soreness. Compression apparel secures the muscles in place to prevent muscular breakdown.
Does it really happen?
Research conducted by Massey University in Auckland found that there was a reduction in delayed-onset muscle soreness 24 hours after exercise when wearing graduated compression stockings after a fast-paced 10K road run. Interestingly, this study found that soreness was reduced specifically in the compressed muscle region. Ninety-three percent of subjects who ran without compression socks experienced lower leg soreness a day after the run, but only 14 percent of the subjects who ran with the socks had similar soreness.
