Abstract

Objective:To investigate the efficacy of neuromuscular electrical stimulation on the abdominal region in women with simple abdominal obesity in order to offer experimental clues for lowering the health hazard of abdomen obesity.

Method:Thirty women with simple abdominal obesity, 50±5.88 years old, volunteered to participate in the experiment. The participants were randomly divided into training group and control group, each 15 subjects. The training group was given neuromuscular electrical stimulating training 30min per day on the rectus-abdominis muscles around umbilicus: with frequency 30Hz, pulse width 300 μs, on and off ratio 1∶3, intensity 10—20mA. Both groups participant in workshops for body weight control once a week.

Result:The women after 12 week electrical stimulating training showed lower BMI,WC, and HC than those in pre-training(P<0.001) and no significant difference was found in BW and WHR of them as comparing with pre-training(P>0.05). In the control group the BW, BMI, WC, and HC did not show significant change during experimental period(P>0.05). Compared with control group, in experiment group BW, BMI, WC,and HC decreased significantly(P<0.05). The women in training group had thinner thickness of visceral fat and greater thickness of rectus-abdominis muscle measured by ultrasonography than those in control group after 12 week intervention(P<0.05).

Conclusion: Twelve week training with neuromuscular electrical stimulation on the rectus-abdominis muscle is a potent visceral fat lossing method for the women suffered from simple ventral obesity. It′s effect is better than only education for weight control.
