a The change in total time period between the two Stroop tests (Stroop 1 and Stroop 2) were plotted against the absolute time period for the Stroop 1 in individual trials. Open circles and small bars indicate their mean values ± SE. Dynamic exercise at 40 and 60 % of maximal voluntary exercise (EXmax) shortened the total time period for the Stroop test, whereas dynamic exercise at 20 % EXmax did not alter the time period (Table 2). The reduction in total time period between Stroop 1 and 2 tests, however, had no significant correlation with the total time period for the Stroop 1 in any exercise session. b Relative percent changes in total time period between the two Stroop tests before and after exercise at different intensities of 20, 40, and 60 % EXmax are compared. #Significant difference (P < 0.05) in the percent changes of total time period between different intensities of exercise
