If you have any interest whatsoever in the role of science in evaluating the claims made by fitness products, you’ll be thrilled about this. The makers of Power Balance bracelets, which purport to “work with your body’s natural energy field” to improve your strength, flexibility and balance, have been compelled by an Australian tribunal to admit that they have “no credible scientific evidence” whatsoever to support their misleading advertising claims, and to offer a refund to unsatisfied customers. For full details, read Ross Tucker’s Science of Sport report here. (And Ross’s follow-up post, in response to those who ask why it matters whether the bracelets are placebos as long as they work, is also worth reading.)
