Purpose:

To analyse the effects of six sessions of external shock wave therapy or radiofrequency combined with a physical exercise program on abdominal subcutaneous fat; which effects on lipid mobilization comparing to the effect of a physical exercise program alone. 

Methods:

36 women aged between 18 and 60 years were randomly allocated experimental group 1 (EG1), experimental group 2 (EG2) and control group (CG). EG1 received external shock wave treatment and EG2 received radiofrequency, both combined with physical exercise and the CG performed only physical exercise. The anthropometric and body composition measurements, mean temperature, adipose tissue thickness, lipid profile, glycerol and interleukin-6 levels were evaluated before and after intervention. The results were analysed using ANOVA and paired samples t-test with a significance level of 0,05. 36 women aged between 18 and 60 years were randomly allocated experimental group 1 (EG1), experimental group 2 (EG2) and control group (CG).

The results were analysed using ANOVA and paired samples t-test with a significance level of 0,05. 

Results:

A significative decrease in the experimental groups comparing to the CG was observed in the subcutaneous abdominal thickness and hip/waist ratio (p0,05). No significative changes were verified in the levels of lipolytic activity, lipid profile and interleukine-6.A significative decrease in the experimental groups comparing to the CG was observed in the subcutaneous abdominal thickness and hip/waist ratio (p0,05).

No significative changes were verified in the levels of lipolytic activity, lipid profile and interleukine-6.

Conclusion(s):

Six sessions of external shock wave treatment or radiofrequency combined with a physical exercise program proved to be more effective than a physical exercise program alone in reducing the subcutaneous adipose thickness and hip/waist ratio. The lipid mobilization was not shown through variations in lipid profile, lipolytic activity and interleukin-6 levels. 

Implications:

It was concluded that six sessions of ESWT or RF combined with an EAP had beneficial effects on decreasing SAT thickness and waist-to-hip ratio, important to the reduction of cardiovascular risk associated with waist-to-hip ratio.
