Effect of an aerobic exercise session combined with abdominal radiofrequency on lipolytic activity in women: Randomized control trial

摘要

Abstract Background Abdominal adiposity is a cardiovascular risk factor; it is assumed that the combination of radiofrequency and physical exercise may decrease this excess of adipose tissue. Purpose To understand whether an aerobic physical exercise session associated with abdominal radiofrequency increases the level of lipolytic activity. Methodology The study analyzes the effect of a combined aerobic exercise session with radiofrequency. Participants were 30 healthy female volunteers, aged 18‐28?years, randomly assigned to an experimental group and placebo group. They were characterized by a sociodemographic questionnaire, the International Physical Activity Questionnaire and the Food Frequency Questionnaire. The groups performed an abdominal radiofrequency session followed by moderate aerobic exercise, assessing glycerol concentration and lipid profile values before and after the intervention. In the experimental group, a percentage of potency was used that allowed to maintain the temperature between 40o C and 42o C to the epidermis. In the placebo group, the power of the radiofrequency was 0 Watt. To compare results, Student's t test was used for a significance level of 0.05. Results There were no significant changes in glycerol concentrations between groups ( P ??0.05). There were no changes in the lipid profile of both groups after the intervention ( P ??0.05). Conclusion The association of exercise with radiofrequency did not present an increased effect on lipolytic activity when compared to the isolated exercise. The application of this technique is a safe intervention.
