STUDY: Brains of healthy, active people > brains of healthy couch potatoes.

By Scott Douglas The brains of endurance-trained middle-aged people show evidence of greater plasticity and metabolic efficiency than the brains of healthy but sedentary middle-aged people, a difference that should lead to better brain function later in life, according to a study to be published in the journal Brain Topography . Researchers at the University of Texas in Austin compared the brains of 28 endurance-trained people ages 40-65 to those of 27 sedentary in the same age group. The endurance-trained people said they ran and/or cycled at least four days a week. The researchers measured concentrations of neural markers such as N-acetyl-aspartate, creatine and choline in the subjects, and also assessed their overall cognitive functioning. Although the researchers found no differences between the groups in mental functioning, they did find higher measures of the neural ...
