CVAT, Continuous Visual Attention Test; SEM, standard error of the mean; %OE, percentage of omission errors; %CE, percentage of commission errors; RT, reaction time; VRT, variability of reaction time. NS, p-value not significant; Min, minimum value; Max, Maximum value; Index = (T2 − T1/T1 + T2) ^∗ 100, where T1 = pre FIFA-Test performance and T2 = post FIFA-Test performance.
