Study: Lactic acid is your *friend,* not your enemy

Scientists now dispute the notion that runners and other athletes have accepted for nearly a century—that lactic acid is a waste product of muscles overwhelmed by anaerobic energy demands. That theory was based on experiments in frog muscles done by Nobel laureate Otto Meyerhof in the 1920s. In contrast, recent studies suggest that the lactate produced by muscles actually helps fuel high-intensity training . George A. Brooks, PhD, professor of integrative biology at the University of California, Berkeley , is among those challenging Meyerhof’s findings. According to Brooks, lactic acid isn’t a waste by-product but a kind of fuel for our muscles. He suggests that our bodies make lactic acid and break it down into lactate, which is converted by the cell's mitochondria into an important source of energy. A 2004 study from California State University, Sacramento , confirmed th...
