Compression tights bring benefits for long-distance runners, but many claims made for the sports apparel do not hold true. Researchers at Ohio State University's Wexner Medical Center recently found that the tights neither reduce muscle fatigue nor make runners go farther or faster. They greatly reduce muscle vibration, but this does not translate into an impact on the level of muscle fatigue as compared to running without tights. Test subjects ran on a treadmill for 30 minutes at 80 percent of their maximum speed on two different days, once with compression tights and once without them. Researchers tracked each runner's body position during their sessions and their leg strength and jump height before and after each run. However, while there may be no measurable benefits, researchers said nothing suggested it is bad to wear compression tights. The study also said that if runners gain a psychological benefit from the tights, then this is reason enough to continue to wear them.
