The effects of whole-body electromyostimulation training with voluntary muscular contractions (WB-EMS),and whole-body electromyostimulation without voluntary muscular contractions (EMS) on total and regional fat mass were examined in sedentary female subjects. The subjects (N = 40) were divided two equal groups as the experimental group (EX),and the control group (CON). The EX group underwent WB-EMS training program during 8 weeks via the WB-EMS training device, while the CON group participated in the EMS program. The electrodes placed on 16 regions of whole body, and than80Hz stimulation frequency was used for all training sequences. The regional body composition analyzer was used for determination of total/regional fat percentage, fat mass, and lean mass of subjects. Differences between variables were assessed using paired samples t test. There were no significant changes between the pre-, and post-test in the total, and regional parameters of the CON (p > 0.05). After the WB-EMS training program, significant decreases were found in the body weight, body mass index, total fat percentage, total fat mass, and fat percentage/fat mass of all regions of the EX (p<0.05). Significance was not found in the total/regional lean mass parameters of the EX(p>0.05).According to the results, the WB-EMS training, which a technologic method in exercise science,improved the total, and regional fat mass of women.
