Abstract des Autors
A number of studies document that physical exercise influences cognitive performance in a variety of ways. Some of these studies present the relationship between the workload of exercise and the activation level of the central nervous system as an inverted-U relationship. Among the factors that could be responsible for diverging results are the participants' individual fitness level and the athletic status. While athletes and non-athletes do not differ in general cognitive skills, athletes are better able to maintain these during physical exercise especially under high exercise intensities. Hence, we hypothesized that the inverted-U function applies for non-athletes but disappears in team sports experts. We compared athletes' and non-athletes' cognitive performance on a measure of attentional behavior under three different physical exercise intensities. Results showed an increase of non-athletes' attentional breadth right up to a certain level of maximal aerobic power before decreasing, as expected according to an inverted-U curve. In contrast, athletes' attentional breadth continued to increase with higher physical exercise intensities. We concluded that physical exercise influences participants' attentional behavior and that individual fitness acts as a moderator of this relationship. Verf.-Referat
