Abstract
The effects of exercise on physical well-being have long been known. Recently investigations have examined whether exercise affects particular aspects of cognition but results are inconclusive, perhaps due to heterogeneous groups of athletes used. We studied two distinct groups of athletes (cross country runners and basketball players) as well as control non-athletes to examine possible effects of sport specific training, using the Flankers attentional task and measuring ERP components related to cognitive evaluation (P300) and motor preparation (LRP). We found no effects of sport specific training on the P300 or the LRP although athletic participation and fitness levels did indicate shorter and higher P300s as well as faster LRP and reaction times. We also found that athletic training yielded a smaller congruency effect on the Flankers task than for the sedentary control subjects.
