It's running season and you've probably seen a few runners wearing compression tights.

Anyone who runs longs distances will tell you that every little thing can help you finish a little faster.

But are these runners getting the benefits they think they are? A new study puts scientific results behind the effects of compression tights.

The theory behind these compression tights is that they compress and reduce the amount of muscle vibration that occurs from running, which is what fatigues your muscles.

Researchers at Ohio State University put runners through two high intensity tests with and without the compression tights. They used motion caption technology and heart rate monitors to measure vibration and fatigue.

What they found was a little surprising. The tights did help compress the vibrations, but it didn't have any effect on the runner’s fatigue. They got just as tired at the same rate with or without the tights.
