Electromyostimulation (EMS) exercise attracts and receives great attention with many studies showings that it has positive effects on body composition. However, the number of studies showing the effects of this exercise when combined with diet is limited. In this context, the aim of this study is to compare the effects of EMS exercise with diet program and EMS exercise without diet program. A total of 104 men and women with an average of age 33.4±0.62 years participated in the study voluntarily. The participants were randomly divided into two groups as dieting EMS group and non-dieting EMS group. Both groups were subjected to the EMS exercise consisting of exercises twice a week, 20 minutes/session a day, for 4 weeks. Body composition measurements of the participants were performed with the InBody 120 Professional Body analysis at the beginning and end of the study. The circumference measurements of the participants were recorded with a tape measure as (cm). In the intra-group change evaluation, significant differences were found between the pre-test and post-test in both groups (p< 0.05). When the comparisons between the groups were examined, it was determined that the dieting EMS group had better results in terms of waist and hip circumference than the non-dieting group. It can be said that EMS exercise with diet is more effective than EMS exercise without diet in terms of body composition.
