Comparison of the effects of shock waves versus radiofrequency on abdominal lipolysis: A randomized clinical trial

High levels of abdominal adiposity mean higher risk of developing cardiovascular diseases. Aerobic exercise per si reduces the risk of developing this type of diseases. Radiofrequency and shockwave therapy showed to be effective in the reduction of localized abdominal fat. Randomized clinical trial, with 30 volunteers in fertile age with overweight and/or obese, randomly and equitably allocated in two experimental groups (1—shockwave therapy and 2—radiofrequency) and one control group. Aerobic physical exercise was prescribed to all groups. The values of anthropometric measurements were measured in two moments. The intervention protocol was performed in a clinic for six weeks, with one session per week. The ANOVA test, paired samples t test, Kruskal-Wallis test, and Wilcoxon test were used to compare the results, for a significance level of 0.05. Of 28 participants completed the study. There were significant differences in waist circumference reduction between the experimental group 1 and 2 when compared to the control group (p = 0.005 and p = 0.014, respectively). There was a statistically significant reduction in navel level circumference in experimental group 1 when compared to experimental group 2 (p = 0.024) and with the control group (p = 0.016). Both resources were effective in reducing abdominal measurements when compared to the control group. However, SWT was superior in reducing the navel level circumference.
