This study aims to verify the effect of dual sports as well as their practice environments on the determination of MI modality and vividness. 240 athletes practicing judo, karate and tennis; boys and girls aged 13 to 15 years, took part in this study. This sample was divided into two age groups: (age-group 1 and age-group 2). The “Movement Imagery Questionnaire - Revised second version” was used to assess the visual and kinesthetic motor imagery vividness. Three non-verbal neuropsychological tests were used, as inclusion criteria, to assess visuospatial memory and reasoning processes. Results show that judo develops kinesthetic motor imagery, tennis develops visual motor imagery; karate doesn’t show any difference between the two modalities. Subjects belonging to age-group 2 had greater MI vividness and boys are more imager than girls. Conclusion: MI modalities as well as its vividness are determined through the type and the environment of dual sports.
