Objective: To investigate the effect of aerobics on the waist-hip ratio and body composition of 30-40-year-old women. Methods: The indexes of waist-hip ratio and body composition of 148 women aged 30-40 years who participated in aerobics exercise in five districts of Lanzhou City for more than one year were followed up and tested by self-control method. Results: Body fat before and after exercise were (29.5 ± 2.4)% and (20.2 ± 2.6)% respectively, and waist and hip ratio were 0.83 ± 0.03 and 0.78 ± 0.02, respectively. Aerobic exercise can increase the lean mass of women (P> 0.05), decrease the percentage of body fat (P <0.001) and lower the ratio of waist to hip (P <0.01). Conclusion: Long-term systematic adherence to aerobics exercises can effectively change body composition and improve body size. So as to effectively prevent cardiovascular and cerebrovascular diseases and improve health.
