The present study examined the effects of a mind-body intervention, often used to decrease symptoms of anxiety, on self-conceptual levels of university students. It was not known if, and to what extent, the combination of mindfulness meditation and group fitness influenced the self-esteem and self-regulation of undergraduate students who self-reported anxiety from the Southern California region. A quantitative quasi-experimental, pre-test post-test design was used to determine if there was a difference in both self-esteem and self-regulation between pre- and post-tests of students who received a mindfulness meditation intervention and participated in group fitness classes. The RSES and SSRQ self-reported scales were used to show differences in scores. The original plan of execution involved the comparison of three groups, which was reduced to one group for analysis, due to the researcher's inability to meet the sample size needed for analysis. The final sample (N = 8) determined that the minimum sample size was still not achieved for a one-way repeated measures ANOVA (n = 28), and a non-parametric analysis was conducted. The results of the sign test showed that while there was a median increase in scores over time, there was not statistically significant differences in scores pre- and post-intervention for both self-esteem (z = 1.51, p = 0.131) and self-regulation (z = 0, p = 1.00). Therefore, there was a failure to reject the null hypotheses. Although the results were not significant for the participants after exposure to the mind-body intervention, the strengths and weaknesses of this study can shed light on similar research practices to improve the mental health and academic success of undergraduate students.
