Effects of Shockwave Therapy Versus Radiofrequency
Condition: Cardiovascular Risk Factor; Metabolic Disease; Photoaging
MeSH terms: Metabolic Diseases
Study type: Interventional

Summary: 
      The main objective of this study is to compare the effect of 6 sessions of shock wave therapy
      versus radiofrequency followed by a protocol of moderate aerobic exercise, in the reduction
      of adiposity and abdominal flaccidity, in females between 18 and 60 years old. As a secondary
      objective, it is intended to understand the mechanism of fat mobilization by these two
      therapies.
    

Detailed description: 
      With the increasing awareness of the population regarding the high rate of obesity and the
      number of deaths per year as a result of being overweight, treatments for reducing measures
      are increasingly sought.

      The evidence shows that the accumulation of fat located in the abdominal region is a risk
      factor for dyslipidemia and arterial hypertension, and a reduction in waist circumference can
      reduce the potential risk of cardiovascular disease.

      In addition to this concern, with the aging of the population and changes in body dimensions
      due to pregnancy or to a weight loss process, body flaccidity is also a growing cosmetic
      complaint, and the result is a less firm and pending skin.

      Physical exercise is a very important agent for combating excess weight, with special
      attention to aerobic physical exercise, which is able to decrease body fat tissue and
      increase the oxidation of fatty acids by 5 to 10 times more than in resting state. The
      evidence points out that the exercise prescription to decrease fat mass should focus on a
      high volume of training (30 to 60 minutes) with moderate intensity (40 to 60% of Heart Rate
      Reserve), performed regularly and mobilizing large muscle groups.

      In order to combat abdominal adiposity, as well as the flaccidity of the region,
      radiofrequency is presented as a possible complementary strategy.

      Radiofrequency is an electromagnetic wave that when applied to skin, generates oscillating
      magnetic fields that move electrically charged particles producing heat in the tissues. The
      amount of heat produced is dependent on resistance.

      Shock wave therapy consists of the application of high energy acoustic waves whose main
      characteristic is the production of a high pressure pulse induced in a short period of time.
      This will generate mechanical pressure waves in the tissues, promoting cavitation, with the
      formation of gas bubbles in the intervening fluids and an increase in local temperature.

      The main objective of this study is to compare the effect of 6 sessions of shock wave therapy
      versus radiofrequency followed by a protocol of moderate aerobic exercise, in the reduction
      of adiposity and abdominal flaccidity, in females between 18 and 60 years old. As a secondary
      objective, it is intended to understand the mechanism of fat mobilization by these two
      therapies.

Intervention type(s): Device; Device; Device
Intervention description(s): Radiofrequency protocol - The radiofrequency protocol was performed in dorsal decubitus, with the head elevated at 45 degrees. The application was in capacitive mode, with a 7cm electrode, always in movement. The duration of the application was established in 15 minutes, maintaining the local temperature between 40 to 42 celsius degrees 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 (5 minutes); body (30 minutes); and cooling (from 5 to 10 minutes). The entire protocol was monitored through the Polar® brand heart rate monitor and watch.; The shock wave device corresponds to the BTL-6000 X-Wave TM with a 20mm transmitter multifocal. The parameters used correspond to the pressure set between 2.8 and 3.5 bar, frequency 15 hertz and 3000 pulses per 10x15 cm area. It was used as a means contact gel for ultrasound, reference 033-051. In this procedure the participants found themselves in the supine position, with a pillow under the head and with the bending knees.
