The purpose of the 10-wk. study was to assess the effect of “aerobics” on self-concepts of college women. 116 college women enrolled in aerobics classes and 177 in 7 nonphysical education classes were given the Tennessee Self-concept Scale in a pretest-posttest design. Using analysis of covariance, with the pretest score as a covariant, significant differences were noted in mean self-concepts between the control group and the aerobics group. The aerobics group scored higher on 7 of the 9 subscales and on the total positive or global self-concept score. No significant difference in mean scores was found for the self-criticism and moral-ethical subscales.
