We investigated whether riding a motorcycle in daily life has beneficial effects on the cognitive functions of healthy subjects. Twenty-two healthy right-handed men, who had a significant break from riding, participated in this study. They were randomly assigned to either the intervention or control group. The intervention group was asked to ride a motorcycle in their daily life for two months. The intervention group showed improvement of their visuospatial cognition compared with the control group. Results of this study indicate that riding a motorcycle in daily life could have beneficial effects in returning riders.
