The purpose of the present study was to evaluate the effects of one session of aerobic exercise associated with radiofrequency in lipolytic activity and lipid profile.
The adipose tissue is the main energetic reserve, being constituted by adipocytes, cells that accumulate lipids inside its cytoplasm, in the form of triglycerides. Fat deposition can occur both in the subcutaneous compartment and in the visceral compartment and is the result of a positive energy balance in which there is an imbalance between the amount of calories consumed and the amount of calories expended. Thus, an excess of energy storage occurs in the form of triglycerides in adipose tissue, which results from a sedentary lifestyle and a diet based on lipid rich nutrients. When fat deposition occurs in abdominal adipose tissue may favor the development of metabolic disorders. Recently the effectiveness of an innovative physiotherapeutic intervention - radiofrequency on adipose tissue has been studied. This therapeutic modality stimulates the lipolytic cascade, converting the triglycerides to fatty acids and glycerol. In this way, radiofrequency seems to aid in the reduction of adiposity. In addition, it assists in the reduction of the inflammatory process related to obesity, by reducing the pro-inflammatory cytokines. The aerobic exercise, due to its low-moderate intensity, enhances the stimulation of lipolysis, by decreasing plasma insulin concentration and elevating the level of catecholamines. In this way, it influences the lipid metabolism, seeming to improve the lipid profile, through the degradation of the triglycerides as energetic substrate. In addition, the regular practice of physical exercise seems to promote a decrease in the inflammation state due to metabolic changes, through the reduction of pro-inflammatory cytokines, namely interleukin-6 and, consequently, C-reactive protein. This study purpose understanding whether an aerobic exercise session associated with abdominal radiofrequency increases the level of lipolytic activity; To analyse the effect of four intervention sessions on abdominal adipose tissue

Radiofrequency protocol - The radiofrequency protocol was performed in dorsal decubitus, with the head elevated at 45º. The application was in capacitive mode, with a 5 cm electrode, always in movement. The duration of the application was established in 20 minutes, maintaining the local temperature between 40ºC to 42 ºC at the epidermis.

Aerobic exercise protocol - 40 minutes of aerobic moderate-intensity exercise (45-55% of reserve heart rate) using Karvonen´s formula, performed on a cycloergometer. The duration of the exercise was divided into three parts: warm-up (from 0 to 5 minutes); body (from 5 to 35 minutes); and cooling (from 35 to 40 minutes). The entire protocol was monitored through the Polar® brand heart rate monitor and watch.
