Fitness Study: Rubber Bands For Strength And Balance

Study Add comments

Last week I took part in a small study for an 8th grade friend of mine’s science project.

He timed how long I could:

  • Stand On One Leg
  • Stand On One Leg With My Ears Plugged
  • Stand On One Leg With My Eyes Closed

Now, I’d done a tough leg workout that morning, but my times were about 3 min, 3 min, and 1 min.  So obviously I rely on my eyes for a lot of my balance.

But, could wearing one of those fancy Power Balance bracelets (a rubber wristband with a “magic” hologram sticker) improve my scores?

According to a recent study… no.

Researchers at the University of Texas tested Power Balance bands on measures of strength, flexibility, and balance.

From the abstract: “The results indicate that the Power Balance® bands did not have an effect on strength, flexibility, or balance.”

Here’s the reference for my fellow science geeks:

In Australia, the makes of Power Balance had to admit that there is absolutely no support for their claims.  The bands continue to sell well elsewhere though.

If wearing a magic rubber band makes you feel better, do it.  Just know that any improvements come from your increased confidence, not from any “harmonious frequencies.”
