Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Transcutaneous microcurrent

This group performed aerobic exercise just after microcurrent in the abdominal region with four transcutaneous electrodes in a parallel position, intensity below the sensitivity threshold and a maximum of 1 milliampere (mA). Every 20 minutes changed from 25 hertz (Hz) to 10 Hz

Group Type EXPERIMENTAL

Transcutaneous microcurrent

Intervention Type DEVICE

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.

Aerobic exercise

Intervention Type DEVICE

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.

Control group

Control group performed aerobic exercise just after microcurrent in the abdominal region with four transcutaneous electrodes in a parallel position, but microcurrent device was switched off.

Group Type PLACEBO_COMPARATOR

Aerobic exercise

Intervention Type DEVICE

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.
