The purpose of this study was to examine the effects of step dance on physical self-perception of female and male university students and also to determine gender differences in the effects of step dance on physical self perception. 73 female and 65 wale university students aged between 18-27 years who look elective courses at the Physical Education and Sport Department voluntarily enrolled in this study. Participants were randomly assigned to experimental and control groups by maintaining balance for gender in each group. "Fox's Physical Self-Perception Profile (PSPP)" was administered to males and females in the experimental and control groups before and after 10-week step dance program. Participants in the experimental group attended step dance sessions of 50 min. per day, 3 days a week for 10 weeks with 60-80 % of their heart rate reserves while subjects in the control group did not participate in any regular physical activity. The results of 2 x 2 x 2 (Experimental/Control x Female/Male x Pre/Post test) MANOVA with repeated measures oil physical self-perception revealed that physical self-perception scores improved from pre-to post-test measurements and these improvements in the subscales of the Physical Self Perception Profile occurred depending on the types of treatment that participants received. Participants in the experimental group improved more than participants in the no-exercise control group but male and female participants did not develop differently on the physical self-perception throughout 10-week step dance program.
