Summary

The purpose of this study was to analyze microcurrent short term effects used with aerobic exercise on abdominal fat.

Detailed description

Nutritional patterns have been changed during twenty-first century with sugar and fat's high proportions that allied to sedentary lifestyle increased body fat. There is already a well establish relationship between total body fat excess, cardiometabolic diseases and increased mortality, knowing that abdominal fat (android pattern), different from body index, presents an additional influence to health risks. Women with their abdominal adipocytes (visceral fat) show an increased lipolytic activity that releases free fat acids to the systemic and portal circulation leading to a metabolic syndrome, increasing the risk of cardiovascular diseases. Aerobic exercise is a way to decrease fat as it stimulates lipolysis through an increase in catecholamine's level resulting from a sympathetic system nervous activity raise. The most used exercise for lipid elimination is the prolonged aerobic moderate exercise with a minimum of 30 minutes. Nevertheless aerobic exercise practice reduce globally lipidic sources and not locally . Electrolipolysis using microcurrent has been used in clinical practice as a technique to reduce abdominal fat. This technique can be applied transcutaneously or percutaneously seeming that the former is not so effective as skin can be an obstacle to the current effect on visceral and subcutaneous fat . Abdominal fat excess is associated with cardiometabolic diseases and can be prevented using microcurrent and aerobic exercise to stimulate lipolysis.

Conditions

• Obesity, Abdominal

Interventions

Type	Name	Description
DEVICE	Transcutaneous microcurrent	Microcurrent in the abdominal region with four transcutaneous electrodes in a parallel position, intensity below the sensitivity threshold and a maximum of 1 mA. Every 15 minutes changed from 25 Hz to 10 Hz.
DEVICE	Aerobic exercise	50 minutes of aerobic moderate-intensity exercise (45-55% of maximal oxygen consumption (VO2 max)) using Karvonen´s formula, performed on a cycloergometer. Were used Borg scale (12-13), Polar® heart monitors to control heart rate and K4b2 to analyze the quantity of oxygen (O2) consumption and carbon dioxide (CO2) produced during exercise.
