Magnet Use for Increased Performance Attracts Skepticism

Study indicates that magnetic therapy does not increase athletic performance

The National Strength and Conditioning Association (NSCA) recently published a study in its official scientific journal, The Journal of Strength and Conditioning Research (Vol.17, No. 2, page 299-302) that confirms magnetic therapy—in the form of shoe insoles—does not improve physical performance. The results show that those looking to enhance physical performance by reducing fatigue through the use of magnets should look elsewhere for a magic training bullet.

In an attempt to improve performance and function at the highest levels possible, many athletes employ various ergogenic aids (ways by which performance can be improved) into their training routines. These aids include mechanical, pharmacological, physiological, nutritional, and psychological practices. One of the newest mechanical aids is magnetic therapy, which allegedly helps athletes perform at their best by relieving pain and fatigue.

Although magnetic therapy has gained popularity in the last few years, very few scientific studies have been conducted to evaluate these claims. Researchers at the University of Central Arkansas investigated the effects of magnetic therapy on selected physical performances.

Fourteen male Division II soccer players volunteered to participate in the study. The subjects were put through a battery of four tests to evaluate athletic performance to include the vertical jump, 40-yard sprint, bench press, and soccer-specific fitness tests. Magnetic insoles were applied during practice and competition sessions for seven weeks.

The results of the study showed no significant improvement between the control group and the treatment group on pre- and post-testing scores, indicating no increase in athletic performance. In fact, both the vertical jump and forty-yard sprint test scores decreased.

This study does not support the claims of proponents that magnetic therapy reduces fatigue and enhances performance. In an attempt to find the competitive edge, athletes resort to using ergogenic aids that are supported with only anecdotal evidence. According to the National Strength and Conditioning Association, the best way to increase athletic performance and decrease injuries is through a proven strength and conditioning program under the supervision of a Certified Strength and Conditioning Specialist®.

Throughout its 25-year history, the National Strength and Conditioning Association has sought to educate its members and increase respect for the strength and conditioning profession. The NSCA fulfills this goal by providing a wide variety of resources such as: exceptional professional journals; cutting edge conferences; scholarship and grant opportunities; educational text and videos; and career services to its 26,000 members.
