Purpose This study aimed to examine the effects of abdominal ultrasound accompanied by complex exercise in shift work employees working in industry. Subjects and Methods Thirty shift work employees were randomly assigned to either a complex exercise group (control group) or a complex exercise and ultrasound treatment group (experimental group). The control group carried out complex exercise five times per week for 4 weeks, while the experimental group performed complex exercise twice per week and received deep ultrasound three times per week for 4 weeks. Results The results showed that there were no significant differences in body composition between the two groups. There were significant changes in weight, lean body mass, body fat mass, and body mass index in the control group; meanwhile, significant changes in weight and body fat mass were observed in the experimental group. There were no significant differences in blood lipids between the two groups. There was a significant decrease in high-density lipoprotein cholesterol (HDL-C) in the control group; furthermore, a significant decrease in total cholesterol was observed in the experimental group, along with significant increases in HDL-C and low-density lipoprotein cholesterol. Conclusion According to the results of this study concerning short-term obesity management programs, complex exercise was effective for improving of body composition and weight loss, while complex exercise combined with abdominal ultrasound had a good effect on blood lipids and secondary complication prevention.
