The purpose of this study is to investigate whether sport participation and driving has any effect on the differences between sexes in visual reaction time (RT). There were three groups (control, exercise, driver), and 20 males and 20 females in each group. The sport participation group was athletes from taekwondo were training at least for five years, minimum three days per week throughout the year. The driver group was males and females were working as representatives of companies and driving at least 20.000 km. annually for the last four years. Each participant was asked to read and sign informed consent and information form at the beginning of the study. Participants were measured three times for simple visual RT, simple visual RT with movement, two and three visual choices RTs for both hands. Descriptive statistics was performed for the four measures according to the groups and sexes. Group and sex differences were examined with MANOVA. The result indicated statistically significant interaction between sex and group for both hands in favor of males for most of the comparisons. Significant differences were also found between three groups and between two sexs for both hands. This study indicated that long term sport participation requiring visual information and driving extensively shorten visual reaction of the participants compared to their counterparts who were not acting in sport and driving.
