In response to these hefty claims, the American Council on Exercise teamed up with the University of Wisconsin, La Crosse to put them to the test. In one trial the subjects wore a Power Balance bracelet, while in the other trial a "placebo" bracelet was worn.
Bracelet assignment was randomized and double-blind to ensure that neither the participants nor the researchers knew who was wearing which bracelet, when. Researchers found no significant difference between the placebo bracelet and the power balance bracelet on any of the tests.
The only finding was that all participants did better on the second trial for each of the tests, regardless of which bracelet they were wearing. The bottom line?
Researchers call the Power Balance bracelet and other performance jewelry a "complete scam. In fact, the Australian manufacturer of Power Balance bands was recently required by the Australian government to release a statement confirming the fact that their claims are not based on any scientific evidence. Generally, if a thing sounds too good to be true, it probably is. If you've already bought a bracelet, don't feel too bad—you're in good company. Power Balance alone sold approximately three million units last year.
Just wear it for fun and chock it up as a learning experience. Sign up for a race online. Effect of a negative ion holographic bracelet on maximal aerobic performance. Still, basic performance accessories continue to sell, as is obvious with the sheer number of items crowding the marketplace. Before you stick on your cynical hat, however, these bracelets may not be a shiny pile of faux-spiritual dinkum after all.
Negative ion bracelet—Good for health? So, you ran out to buy a Power Balance bracelet, and it turned out not to be the Green Lantern power ring you were expecting. Never fear! In one study of the early bracelets, researchers concluded that while the bands worked no better than the placebo, some wearers still might benefit from them because they simply have more self-belief while wearing it.

DOI: Other researchers suspect that the same may be true of more contemporary performance jewelry. While the technology behind the Power Balance and its kin might not work, they can create a placebo effect that puts you in the right headspace to outperform yourself.

With new technologies and an understandable long-standing skepticism about whether a bracelet can turn you into a winner, Power Balance and its peers seem to be getting less attention. Focus is shifting from energy-wear to smart gear. Silina Y, et al.

Some recent research gives them two enthusiastic thumbs up and a heart reaction for their ability to track and improve performance. Their findings suggested that when some athletes wear a sensor, they may reach the finish line more quickly and are less likely to face-plant while doing so. One of those athletes who testify about the bracelet's efficacy is the former NBA superstar and legend, Shaquille O'Neal. The former NBA player said that he heard about these wristbands when someone did a test on him with his teammates.
They won the game and ended it with a point lead. O'Neal also stated he felt something in his body while wearing the bracelet, so he never took it off whenever he played. When he did, his energy went back to normal. Thus, he has never removed it from his wrist since then.

The bands claim to help tune the wearer's electromagnetic frequency to the same level of universal frequency. Our whole presence, says the marketer, lies in the efficient transfer and balance of positive and negative ions.
