According to the latest study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital had revealed that regular exercise by young adults improves their IQ. In this study, 1.2 million men were enrolled who were both between 1950 and 1976. The physical test and IQ analysis was done for men who were enroll for this study. The results clearly indicates the link between increased physical fitness and IQ improvement which mainly includes logical thinking and verbal comprehension.
Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital said that being physically fit means to have good heart and lung capacity and that brain gets plenty of oxygen which may be the reason for clear link with fitness. Maria ?berg, researcher at the Sahlgrenska Academy added that youngsters who improve their physical fitness between the ages of 15 and 18 shows the considerable increase in their cognitive performance.
The link between physical fitness and mental performance has also previously been demonstrated in studies carried out on animals, children and old people. However, studies on young adults have been contradictory to all previous studies. It is possible that around the age of twenty brain may still change rapidly as a result of both cognitive and emotional development.
