Introduction Abdominal fat is indirectly correlated with many of the adverse health effects of obesity.[1] Whole-body Electrical Muscle Stimulation (WB- EMS) is a popular training technology which offers an easy way to start an effective and safe workout.[2] Although researches have shown Result After 10 weeks of body weight training with WB-EMS, there is a significant difference in visceral fat between pre-test and post- test (P<0.001). Also, there was a significant difference between the pre-test and post-test in the abdominal circumference measurements after performing the exercise protocol (P<0.001). Therefore, the participants had a significant decrease in both the amount of visceral and the size of the abdominal circumference. In other words, WB-EMS exercises showed a 13% decrease in visceral fat and a 3% decrease in abdominal circumference in the subjects. Discussion & conclusion The WB-EMS have positive effects on reduction of visceral fat and abdominal circumference. Generally, WB-EMS can be performed without heavy resistance. bodyweight exercises are also without additional resistance. this combination of training methods probably can be beneficial for people who have joint injuries or are unable to use their muscle strength. This method also can be used for the people who face some physical limitations such as soft joints, weak muscles, etc. significant changes on body composition values as a result of EMS training [3]. Also bodyweight training (BWT) known as a beneficial exercise based on classic principles of physical education.[4] So the question arises, what effect will the combination of these two training models have on our body composition? Therefore the purpose of this study was to determine the effect of BWT trainings with WB-EMS on visceral fat and abdominal circumference in middle-aged men. Methods The statistical population of this study consisted of a group of middle- aged men [(N=12), mean [±SD] age, height, VF (Visceral fat) and AC (Abdominal circumference), 48±5.9 years, 174.6 ± 5.7 cm, 111.7±35.1 cm2 and 97.6±9.3 cm respectively]. The implemented protocol included 10 weeks of training, a total of 20 sessions, each lasted 20 minutes. Experienced trainers supervised all training sessions. subjects wore a special vest with integrated electrodes that was used to apply electrical stimulation to specific muscles by bipolar impulses at a frequency of 85 Hz and a pulse width of 350 microseconds. The training program includes: 5 minutes of general body warm-up, standing fly, squat, pullup, bending one knee in a standing position, side lateral raise, pair elbow flexion, pair elbow extension, standing abs and 5 minutes of light stretching exercises. 2 sets that include 8 repetitions with concentric and eccentric contractions, 2 and 4 seconds, respectively.[5] body composition analysis test, taken before and after the intervention. Research data were analysed with SPSS 26 software.
