This study may be of interest to you and your networks: http://www.eurekalert.org/pub_releases/2013-07/uog-cpi072413.php Cognitive performance of adolescent girls who walk to school is better than that of girls who travel by bus or car. Moreover, cognitive performance is also better in girls who take more than 15 minutes than in those who live closer and have a shorter walk to school. The authors analyzed a sample of 1700 boys and girls aged between 13 and 18 years (808 boys and 892 girls) in five Spanish cities (Granada, Madrid, Murcia, Santander and Zaragoza). Cognitive performance was measured by applying the Spanish version of an educational ability test. Participants completed this standardized test that measures intelligence and the individual's basic ability for learning. The test assesses command of language, speed in performing mathematical operations, and reasoning. In adolescence, the plasticity of the brain is greatest. The researchers affirm that, during adolescence, "the plasticity of the brain is greater than at any other time of life, which makes it the opportune period to stimulate cognitive function". However, paradoxically, adolescence is the time of life that sees the greatest decline in physical activity, and this is greater in girls. Therefore, the authors of the study think that "inactive adolescents could be missing out on a very important stimulus to improve their learning and cognitive performance".
