This research was carried out to examine the effects of pilates and zumba exercises on sedentary women's psychological well-being and happiness levels. A total of 20 women voluntarily participated in the study. Participants were randomly divided into pilates group and zumba group. Both groups carried out branch-specific training of 60 minutes, 3 days a week, for a total of 6 weeks. Oxford Happiness Scale Short Form and Warwick-Edinburgh Mental Well-Being Scale were administered to the participants twice, at the beginning and end of 6 weeks. Statistical analyzes were performed using the SPSS-21 package program. Shapiro-Wilk test was used to determine the normality distribution of the data. Since the data showed normal distribution, the Independent-Sample T Test was used for in-group comparison, and the Paired-Sample T Test was used to determine the difference between groups. As a result of the study, when the pre-test averages of the Oxford Happiness Scale and the Warwick-Edinburgh Mental Well-Being Scale were compared before and after the exercise, no significant difference was found in the pre-tests of the pilates and zumba groups according to both scales (p>0.05). Significant differences were found in the posttests of zumba groups (p>0.05).

Finally, in our study, when the changes in the pre-test and post-test measurements of the Oxford Happiness Scale and Warwick-Edinburgh Mental Well-Being Scale averages of the pilates exercise group were examined after 6 weeks of exercise, as a result of the independent sample t-test, the Oxford Happiness Scale (eta squared=2,617) and Warwick- A significant difference with high effect values ​​was found compared to the mean of Edinburgh Mental Well-Being Scale (eta squared=1,623) (p<0.05). In the Zumba exercise group, when the changes in the pretest and posttest measurements of the Oxford Happiness Scale and Warwick-Edinburgh Mental Well-Being Scale mean after 6 weeks of exercise were examined, the independent sample t-test resulted in the Warwick-Edinburgh Mental Well-Being Scale mean (eta squared=0,859). A significant difference was found with high effect values ​​(p<0.05). In line with these findings, it was concluded that the effect of pilates training on psychological well-being and happiness levels was good in pilates and zumba groups.
