We all know how physical exercise benefits the body, strengthening muscles and improving stamina, but is it also good for the brain? A
new study out of University of South Carolina is showing some interesting results. The eight-week study compared the brains of mice that spent time exercising on a treadmill to another group of rodents that just laid around doing nothing. The active group showed a marked increase in newborn mitochondrial organelles in the brain tissue, a response similar to what happens in the cells of muscle tissue. Mitochondria are the tiny organelles found inside the nucleus of most eukaryotic cells that power many cellular processes. The brain tissue of the couch-potato group showed no change in cell make-up. The hope is, if the same mitochondrial biogensis takes place in the human brain during exercise, it could act as a safeguard against the development of Alzheimer's, Parkinson's or other human brain diseases.
