The results indicate that the Power Balance® bands did not have an effect on strength, flexibility, or balance. Balance was measured by the BIODEX System.Īfter all the measurements and tests were completed, this is what the study found: Strength and flexibility were measured using a MicroFit system (strength was measured via a bicep curl and flexibility via a sit-and-reach). Using separate bands, their legitimacy blinded from participants and researchers alike, prevented any researcher or participant bias and enabled researchers to make comparisons across the tests, i.e., if the “real” bracelets do not outperform the fake ones, the “real” bracelets do not work.įurthermore, the actual testing of these criteria were subjected to common methods that would suss out if there was any actual benefit to wearing these bracelets. Each of the subjects participated in three treatment sessions, consisting of Power Balance®, placebo band, and no band. This way there would be no confounding variables or subtle biases that could skew results. To settle this, the study used 24 subjects (10 males and 14 females) in a counterbalanced, double-blinded, placebo-controlled subject design. Many of these bracelets also claim to have research that supports them, however, it rarely if ever is controlled in a legitimately scientific way. So, if the claims are to be considered accurate, then empirically testing their own criteria should yield at least some benefit to users being tested. So what we would be looking for, and what is claimed by these products of all kinds, is an increase in balance, strength, and endurance (let’s throw flexibility in there for good measure). A recent study concluded that iRenew’s SFR technology may promote, balance, strength and endurance. IRenew bracelets are infused with Selective Frequency Resonance technology which makes them different from every other wristband on the market. Here’s an example taken from the iRenew website: The Claimsīefore we go on to the study, it will be useful to remind ourselves what the general claims of these balance bracelets are. However, we now have a brand new study appearing in the Journal of Strength and Conditioning Research that rigorously puts the claims of these balance bracelets to the test. That was all based upon knowledge of physics and the red flags of pseudoscience.
