This study compared the differences in spatial relations, spatial ability, and reasoning ability between female swimmers and sedentary people. Fifty-eight participants (24 swimmers and 34 sedentary females) were recruited to complete the PMA E & R tests (Primary Mental Ability Test) and the DAT-SR test (Differential Aptitude Test). Findings indicated that swimmers scored higher in spatial relations, spatial ability, and reasoning ability. The practice of competitive swimming appears to have a positive relationship with the spatial relation, spatial ability and reasoning ability
