Power Balance is the original brand of hologram bracelets claimed by its manufacturers and vendors to "use holographic technology" to "resonate with and respond to the natural energy field of the body", and increase sporting ability.[1] Numerous independent studies of the device found it to be no more effective than the placebo effect for enhancing athletic performance, and the manufacturer was forced by the ACCC to retract any previous claims in 2010.

The product was originally promoted at trade shows in the beginning of 2006 utilizing applied kinesiology as its most effective sales tool. They then began selling the product in 2007 and had amassed countless celebrity endorsements many free and some paid[1] they had became a trend among high school, collegiate and professional sports in 2008-2012 although bands are regularly sighted on athletes today, those 5 years were the biggest boom for Power Balance. Leading one journalist to say that "a growing number of professional sportsmen and their attendants are starting to sound like New Age crystal healers."[2] Another journalist gave Power Balance the CNBC Sports Product of the Year in 2010.[3]

Power Balance Headquarters which was located in Laguna Niguel, California at the time, denied that they made any medical or scientific claims about their products,[5] but after an Australian Competition and Consumer Commission ruling, the Australian distributor of Power Balance was forced to recognize and retract any possible claims.[6] The company had been the focus of significant criticism, particularly for false advertising. It has been described as "like the tooth fairy"[4] and a "very successful marketing scam".[5] Although Dylan Evans, a lecturer in behavioral science at [https://www.ucc.ie/en/medical/ Cork University's School of Medicine] and author of [https://www.goodreads.com/book/show/141782.Placebo Placebo] stated "I was really impressed by the marketing. They have managed to get away without deceiving anyone in the sense of an overt lie. There are no claims on the packaging itself."They don't make any reference at all to any health outcomes. They leave that as an inference that most people will draw"[6]

By the end of 2011 the company was reported to be on the edge of going out of business after allegedly having to settle a $57m lawsuit, in the course of which company executives acknowledged that their past claims to improve strength and balance were not backed by science.[7] It filed for Chapter 11 bankruptcy due to a multitude of lawsuits, but the brand has since been transferred to a new company, Power Balance Technologies and is still selling Power Balance bands and other items today. www.powerbalance.com

Power Balance seems to have added to there product line as well using other more widely accepted sales tools for selling their products, Titanium[8] and Ion producing powder in some of their products. Although they do not make any claims on the company's website they still seem to sell the original bands as well.

Efficacy

In 2011, researchers from RMIT's School of Health Sciences reported the results of an independent, randomized and controlled trial with double blind design. They found no difference in balance between people using a holographic wristband and those wearing a placebo.[9]

On October 28, 2010 Olympic champion gymnast Dominique Dawes, working for Yahoo Weekend News and Independent Investigations Group (IIG), tested Power Balance bracelets for their claim that they improve balance, flexibility and strength. According to IIG investigator Dave Richards "There was one 'legitimate' Power Balance bracelet, and 3 'sham' bracelets that had the hologram removed from them. The experiment was double-blinded, all bracelets were wrapped with tape so no one present knew which bracelet was real and which were fakes. Neither the participants nor the people recording the scores knew which bracelet was 'real' until after all participants had completed their runs and their scores were recorded." The results indicated that there was no benefit for those that had a real holographic bracelet compared to those who had a placebo.[10][11][12]

In December 2009, an informal double-blind test was performed on the Australian television program Today Tonight, led by Richard Saunders from the Australian Skeptics. The results showed strong evidence that any effect of the holograms is too small to measure against the placebo effect.[13]

A study at the University of Wisconsin tested the effects of Power Balance bracelets on a group of NCAA athletes. One set of the athletes received the Power Balance bracelet, while the other received a placebo bracelet. The athletes were subjected to tests of flexibility, balance, and strength, after which, the athletes switched bracelets and performed the tests again. The study found that the Power Balance bracelet had no effect, compared to the placebo, on the performance of the athletes.[14]

A group of students skeptical of the claims conducted a test which showed "no significant difference between the real wristband and the fake".[15] Researchers commissioned by the BBC also found that the bands were placebos,[16] A 2012 Skeptical Inquirer study showed that in a double-blind test of performance on an obstacle course, sixteen volunteers showed a difference in performance no greater than chance.[17]

Criticisms

Many experts are of the opinion that the Power Balance bracelet is nothing more than a placebo. Victor Thompson, a sports psychologist based in London, is quoted by the Daily Mail as saying: "I'm not aware of any research that supports the technology behind these bands". Greg Whyte, professor of applied sport and exercise science, Liverpool John Moores University observed that "For generations there have been devices that claim to mediate the body's flow of energy, from acupuncture to copper wristbands and, latterly, magnets ... In most instances, the 'proof' is based on anecdotal evidence."[19]

The Center for Inquiry noted Power Balance's use of pseudoscientific applied kinesiology tests, which it described as "problematic and full of flaws". The illustrative videos on the company's website were considered vague and unclear, and the Center noted that "most people's flexibility seems to improve from their first stretch to their second stretch regardless of whether they are wearing the bracelet".[20]

In the Skeptical Inquirer in 2010, Harriet A. Hall wrote that she would believe anyone who claimed that a Power Balance product made them feel better, or that their performance was improved, but would not be convinced that "the improvement has anything to do with bioresonating frequencies in the holograms—or even with the cards themselves. It's like the tooth fairy. Tell me money appears under your pillow, and I will believe you. But that won't convince me that the tooth fairy did it." [21]

Australian consumer advocate group CHOICE recognized Power Balance in their 2010 Shonky Awards. The Shonky Awards are intended to "name and shame the shonkiest rip-offs and scams."[22] The Sydney Morning Herald concluded the Power Balance bracelets “did little else than empty purchasers’ wallets”.[23]

In November 2012, Dallas Mavericks owner Mark Cuban criticized an endorsement deal between the NBA and Power Balance. When a similar product was pitched on the ABC reality series Shark Tank, which features Cuban as one of the "sharks", he dismissed the product, stating "No, I'm allergic to scams. Seriously, this is not new. It's been disproven. What you saw is the placebo effect. There's athletes that wear it. It's a joke. It's a scam. It's not real."[24]

A study by Verdan et al. (2012) examined the effects of the Power Balance band on static balance, hamstring flexibility, and arm strength in adults. The study involved 10 male and 14 female subjects. A counterbalance, double-blind, placebo, controlled within-subject design was used. Each of the subjects participated in 3 treatment sessions, consisting of Power Balance, placebo band, and no band. This study found that there were no statistically significant differences in strength, flexibility, or balance with regard to the treatments used. Therefore, these results suggest that the Power Balance bands did not have an effect on strength, flexibility, or balance.[25] This study is important in disproving the claims made by Power Balance since it controls for the placebo effect and indicates that any perceived benefit from using the Power Balance is due to the placebo effect.

Legal issues

In November 2010, the Australian distributors of "Power Balance" were ordered by the Therapeutic Goods Administration Complaints Resolution Panel to drop "false and misleading" claims that the wearers would experience "up to a 500% increase in strength, power and flexibility", and ordered the claims removed from the company's website and a retraction posted within two weeks.[26] The Junta de Andalucia fined the Marbella-based subsidiary a sum of €15,000 for false advertising; consumer organization Facua are appealing to the Health Department for an increased fine as they consider this insufficient.[27]

Also in November 2010 Power Balance filed suit against Microsoft for infringement of trade dress in respect of the Xbox Kinect, after the company announced a range of promotional wristbands.[28][29]

In December 2010, the Australian Competition and Consumer Commission (ACCC) obtained from Power Balance Australia Pty. Ltd. an undertaking to take a number of actions in relation to correcting their misleading advertising,[30][31] including:

  1. publishing, at its own expense, corrective advertisements&91;32&93;
  2. ceasing to claim that the products&91;33&93;
    • will improve the user's balance, strength and flexibility; or
    • are "designed to work with the body's natural energy field";
    • nor, in conjunction with the Products, make claims that "Power Balance is Performance Technology" or use the phrase "Performance Technology"
  3. ceasing to manufacture or import products containing the words "Performance Technology"&91;34&93;
  4. blacking out the words "Performance Technology" on its packaging&91;35&93;
  5. replacing its promotional and marketing material&91;36&93;
  6. offering full refunds, plus postage&91;37&93;

Power Balance Australia chief executive Tom O'Dowd admitted that "we'd made claims in the start that said that our product improved strength, balance and flexibility, and we didn't have the scientific peer reviewed double blind testing or the level of proof that we needed to substantiate those claims".[38] ACCC chairman Graeme Samuel stated "It's a crock frankly. And we're very disappointed that so many people have paid hundreds of thousands if not millions of dollars to buy these Power Bands."

Power Balance Australia was required by the ACCC to run a series of advertisements in Australian media containing the following text and to unconditionally refund those they mislead:[39][40]

"In our advertising we stated that Power Balance wristbands improved your strength, balance and flexibility. We admit that there is no credible scientific evidence that supports our claims and therefore we engaged in misleading conduct in breach of s52 of the Trade Practices Act 1974. If you feel you have been misled by our promotions, we wish to unreservedly apologise and offer a full refund."[41][42]

In December 2010 Italy's Antitrust Authority fined Power Balance 300,000 euros (and another company 50,000 euros) for not having scientific proof of the claims made.[43]

In September 2010, the Dutch Advertising Code Commission (RCC)[44] made the following decision in the case where FIR-TEX Ltd,[45] the plaintiff, had put Surf Unlimited Trading BV, distributor of power-balance in the Netherlands, on trial with the following complaint:

"Advertiser claims on its website that the use of the Power Balance Bracelet improves balance, strength and agility. These allegations are not backed with any single (scientific) evidence. The plaintiff believes that this method of advertising is in conflict with the Dutch Advertising Code (NRC) as the link between wearing the bracelet and the health of the wearer has not been determined in any way."

The verdict of the Commission was as follows:

The Commission considers the advertisement in opposition of the provisions of Article 7[46] NRC. It recommends advertiser not to advertise in such a way anymore.

In January 2011, a suit was filed in the United States against the company for fraud, false advertising, unfair competition and unjust enrichment.[47] Power Balance agreed in September 2011 to settle the class action lawsuit. The settlement terms entitled Power Balance purchasers to a full $30 refund plus $5 shipping. A hearing to finalize the agreement was canceled after Power Balance filed for Chapter 11 protection.[48]

In November 2011, Power Balance filed for bankruptcy after suffering a net loss of more than $9 million that year.[49]

In 2012 the company announced it was trading under new ownership as Power Balance Technologies Inc.[50]
