At the Experimental Biology 2008 scientific conference in San Diego, Dr. Chad C. Carroll working with Dr. Todd Trappe of the Human Performance Laboratory at Ball State University, Muncie, Indiana, reported some surprising results. Elderly men and women, taking Ibuprofen (as in Advil) and acetaminophen (as in Tylenol) had bigger gains in muscle building and strength, than elderly exercisers taking a placebo.
