The peer-reviewed literature doesn't support the use of magnets. Period.
That said, I have seen an unpublished study looking at increases in strength when an individual lifted a pair of dumbells (10 seconds in an "iron cross" if I remember correctly), and then moved onto magnetic inner-soles and was able to lift a heavier set of dumbells.
"Yeah right," I thought.
At APTA conference, I actually tried doing just that on my own. I was in fact able to lift a significantly heavier load when standing barefoot over the magnets. I have no idea why. Was this a true effect? Did standing in a magnetic field (also an electric field) make my neurons somehow "more ready" to fire? If so, how did the field at my feet affect deltoid strength? OR . . . was it just Hawthorne effect (aka. Novelty Effect)?
We need to look into these effects, publish the results, and examine the neurophysiology before we start treating patients . . . and billing them . . . for this kind of stuff.
