But wait! When you factor in "after burn," couldn't weightlifting still be some miracle calorie-consumer? Sorry, Conan, but after-burn — technically called excess post-exercise oxygen consumption, or EPOC — does exist, but only to a small degree. As I've covered in an earlier column, the EPOC of interval training is insignificant. And the same holds true for weightlifting.
A quick scan of the research:
• In 1995, researchers at the University of Limburg in the Netherlands published a study in Medicine & Science in Sport & Exercise on 21 male subjects and determined that weight-training "has no effect" on RMR.
• In 1994, researchers at the Royal Veterinary and Agricultural University in Denmark compared 10 bodybuilders with 10 lean (you are so puny!) subjects. Published in the American Journal of Clinical Nutrition, the report found that intense weight-lifting did not result in any measurable EPOC.
• In 1992, researchers from the University of Texas at Austin compared intense weightlifting with intense aerobic exercise on 47 males and reported in the American Journal of Clinical Nutrition that "RMR did not significantly change after either training regimen."
