Bethesda, Md. (Sept. 16, 2011)Researchers have long known that regular exercise increases the number of organelles called mitochondria in muscle cells. Since mitochondria are responsible for generating energy, this numerical boost is thought to underlie many of the positive physical effects of exercise, such as increased strength or endurance. Exercise also has a number of positive mental effects, such as relieving depression and improving memory. However, the mechanism behind these mental effects has been unclear. In a new study in mice, researchers at the University of South Carolina have discovered that regular exercise also increases mitochondrial numbers in brain cells, a potential cause for exercises beneficial mental effects.
Their article is entitled "Exercise Training Increases Mitochondrial Biogenesis in the Brain." It appears in the Articles in PresS section of the American Journal of Physiology Regulatory, Integrative, and Comparative Physiology, published by the American Physiological Society.
