DOI: Other researchers suspect that the same may be true of more contemporary performance jewelry.

So placebos can offer benefits with absolutely no risk. Kaptchuk TJ, et al. Placebos without deception: a randomized controlled trial in irritable bowel syndrome. Not even close. 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.

Wearable sensors and devices continue to get smarter and more complex. 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. Seshadri DR, et al.

Especially if said hat collects numerical data about your on-fleekness, and your friends can make more educated suggestions about which kicks to wear with it. Admittedly, we may be some way off this technology. Power Balance and other low-tech performance-enhancing accessories might work, but only if you count that tricky placebo effect. A better bet may be trying one of the emerging smart accessories. You can use this data to alter your technique or activity level.

The Effect of Negative Ions. He could tell I was immediately skeptical, so he swooped in on my friend instead. The man asked him to stand on one foot with his arms outstretched. And with that, he easily sent my friend stumbling.
Later on that weekend, I started noticing lots of people wearing these bracelets, and others like them. And one of the most popular brands, Power Balance powerbalance. And people have been buying them indeed. Power Balance reportedly sold three million units in the past three years. Each subject completed two trials of four tests: trunk flexibility, balance, strength and vertical jump. The first three tests mimic the tests used on the Power Balance Web site www.
The vertical jump test was added to gauge lower-body power. The tests were presented in the same order for all subjects, without a warm-up, and subjects were required to not have done any exercise prior to testing on that day. The order of bracelets worn was completely randomized and double-blinded so that neither the subjects nor the examiners knew which bracelet was being worn for which trial.
Half of the subjects wore the Power Balance bracelet for their first trial while the other half wore the placebo bracelet for the first trial. The amount of trunk rotation was measured in degrees using a calibrated grid. Balance: Subjects were instructed to stand with feet together and arms extended straight out to the sides, and lift the right foot approximately 15 centimeters off the ground.
Once the subject was in position, the examiner pushed straight down on his or her right arm with a Lafayette Manual Muscle Tester MMT—a device that measures the amount of force exerted by the examiner until the subject lost his or her balance or broke form. As the examiner exerted force straight down, the subject tried to resist.
The amount of force required to cause the subject to either move his or her feet or break form was recorded. Vertical Jump: Subjects were asked to jump as high as possible, touching the highest vane they could reach on the Vertec Vertical Jump Tester. Jump height was measured in centimeters. After the numbers were crunched, researchers found there was no significant difference in flexibility, balance, strength or vertical-jump height between the Power Balance and placebo trials Table 1.
Trunk flexibility was 9. Since no warm-up was given, this improvement in flexibility was attributed to the subjects being warmed-up for their second trial. For the balance test, it took 16 percent more force to throw the subjects off balance on the second trial. And for the strength test, 7 percent more force was required to cause a break in form on the second trial.
After the numbers were crunched, researchers found there was no significant difference in flexibility, balance, strength or vertical-jump height between the Power Balance and placebo trials. During the vertical jump test, subjects jumped nearly 2 centimeters higher on their second trial.
