Energy force bands are popular fashion, and sports, accessories. Manufacturers and marketers of the bands claim they improve balance and athletic performance. Sports superstars, such as NBA basketball player Shaquille O'Neal and Major League Soccer player David Beckham, wear them and say the bracelets help them perform better. Others say that they do nothing to improve performance.
Manufacturers of energy force bands — also called power balance bracelets — state that the world is tuned to an electromagnetic frequency. Energy Force USA, a marketer of the bracelets, says that the frequency is 7.3814 hertz. The bracelets claim to assist in tuning your electromagnetic frequency to that same universal frequency. "The totality of our existence," Energy Force USA says in its marketing material, "depends on the efficient exchange and balance of positive and negative electrical charges called ions."
The bracelet puts your body's electrical charges in better balance, according to one bracelet retailer who sells to golfers. Those electrical charges are called ions. The bracelets are said to produce negative ions to reduce the impact on the body of an onslaught of positive ions from computers, pollution, cell phones and other sources that put you out of balance in the first place.
There are multiple benefits that manufacturers claim the bracelets provide by putting you in better balance with the world's frequency. The bracelets improve physical balance and muscle power. They also claim to give you more range of motion. In addition, there are claims of mental benefits, including greater focus, more intense concentration and improved awareness.
Researchers in a study at the School of Health Science at the Royal Melbourne Institute of Technology found that energy force bands had "no effect on balance and stability." Researchers at the school further extrapolated results from the study on 42 subjects to examine claims about the bracelet's primary benefit, which is improving balance. Because balance didn't improve in the study, according to the chief investigator, Dr. Simon Brice, "the validity of other purported benefits seems highly unlikely."
