The strongest links are for logical thinking and verbal prehension. But it is only fitness that plays a role in the results for the IQ test,and not strength. “Being fit means that you also have good heart and lung capacity and that your brain gets plenty of oxygen ,” says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. “This may be one of the reasons why we can see a clear link with fitness, but not with muscular strength . We are also seeing that there are growth factors that are important.”By analyzing data for twins, the researchers have been able to determine that it is primarily environmental factors and not genes that explain the link between fitness and higher IQ.“We have also shown that those youngsters who improve their physical fitness between the ages of 15 and 18 increase their cognitive performance,”says Maria Aberg, researcher at the Sahlgrenska Academy and physician at Aby health centre. “This being the case, physical education is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects.”The researchers have also pared the results from fitness tests during national service with the socioeconomic status of the men later in life.
